Buying a castle in the UK
Migration Program Details & Application
Program Overview
Purchase a castle in London, England
Project Description
I. Core Budgeting Understanding
Overview of price ranges for British castles:
• Average price of castles across the UK: currently around £2,217,394, requiring a down payment of around £333,000 (approximately 15%), with monthly payments exceeding £10,000.
• Castles and estates in and around London: scarce, starting at £2.5 million – over £7.5 million.
• Castle prices compared to the average London house price: The average price in London is only £530,000–£750,000, while castle prices are 3 to 10 times higher than ordinary houses.
II. The Real Market Form of London's "Castle"
Option 1: Apartments sold separately within a historic castle
Vanbrugh Castle, located next to Greenwich Park, is a prime example of a "castle residence" in London. Built in 1718, it is a Grade I listed building with a 2.5-acre shared garden and four independent apartments. A four-bedroom apartment was previously listed for £2,750,000 (approximately 3,139 sq ft/292 sq m) under a share-of-freehold arrangement. This property had been listed by multiple agencies for five years without selling, but a single agency handled the sale within seven weeks, demonstrating the continued market appeal of scarce castle assets through a reputable agent.
Type Two: Independent Units within Castles and Manors (Outskirts of London)
For example, Baron's Wing (7,000 square feet, 5 bedrooms) in Appleby Castle was sold for about £1.79 million, but the castle is located in Cumbria on the edge of the Lake District in England, a 4-5 hour drive from London, and is not strictly a "London" property.
Option 3: Alternative Solution – Historic Building Renovation Projects (A More Practical Choice)
• Demand for historic buildings in London (old schools, churches, warehouses, etc.) is expected to rise sharply from 2025 onwards. Searches for "buying new housing" have decreased by 641 TP3T, "newly developed properties" have decreased by 471 TP3T, while searches for historic buildings have surged by 601 TP3T.
• In the London market, only about 15.81 TP3T of listed properties are period properties. The Maida Vale area has the highest buyer activity for period properties (26.41 TP3T signed or in the process of being transacted), followed by Regent's Park (17.21 TP3T) and Holland Park (15.51 TP3T).
III. Market Dynamics in 2026
1. The era of buyer's bargaining power has arrived in the ultra-luxury home market. Prices in top communities like Knightsbridge and Belgravia are 29.51 TP3T lower than their peak, and Chelsea is 20.51 TP3T lower. Average prices for luxury homes in central London have essentially returned to levels seen 12 years ago, with the market-wide average discount exceeding 101 TP3T, the highest level in five years. Buyers are extremely discerning regarding quality, value, and long-term potential.
2. The UK market is recovering, and lending conditions have eased. The Bank of England's benchmark interest rate will fall to 3.751 TP3T by the end of 2025, and mortgage rates will fall to a near five-year low of approximately 41 TP3T–5.51 TP3T.
3. Overseas buyer activity remains active. The UK does not restrict foreign citizens from purchasing property; a visa or residency status is not required. However, purchasing property does not grant residency—the purchase itself is legally invalid for visa applications. A valid visa is required to actually move in.
4. Long-term supply-demand imbalance supports value. The supply of ultra-high-end properties has been in short supply for a long time; buyers who value historical heritage, space, and uniqueness keep the premium for the scarcity of manor and castle-type luxury homes high.

Eligibility & Requirements
Evaluate
I. Market Positioning and Price Range of British Castles
Reference price range for different property types in different zones
Apartments/historic residences within castles in prime London locations (Greenwich, Kensington, etc.) priced between £2.5 million and £7.5 million+.
High-end Home Counties (Surrey, Kent, Berkshire, etc.) 18th–19th century manors/castles: £1.5 million–£5 million
The average price of a castle across the UK is £2,217,394 (including castles requiring renovation).
Affordable alternatives to small, renovated castles in the English/Scottish/Wales countryside: £300,000–£800,000
Additional costs must also be considered, including renovation and management costs, as well as stamp duty surcharges for overseas buyers and budget for the maintenance of historic buildings.
II. Core Advantages
1. Zero buyer eligibility requirements. UK law fully permits foreigners to purchase any type of residential property throughout the country (England, Scotland, Wales, and Northern Ireland) without needing a visa or residency permit.
2. Mature legal protection system. The UK property registration system is transparent, and both Share of Freehold and Leasehold holders have clearly defined legal rights and responsibilities; buyer's lawyers handle legal research, contract review, and fund verification.
3. The "Historical Heritage Exemption" Policy for Inheritance Tax and Capital Gains Tax. Heritage buildings, estates, and works of art possessing "outstanding historical or architectural value" are eligible for a Conditional Exemption upon HMRC certification. The 100% exemption covers IHT and CGT, provided the owner commits to proper preservation and appropriate public access. These buildings are also eligible to establish heritage preservation trusts for further tax reductions. These heritage tax regimes are a significant financial boon for large-scale historical buildings like castles.
4. Stamp Duty Reduction and VAT Incentives. Residential renovations are eligible for a maximum VAT rate of 5% (standard rate is 20%); new residential buildings are eligible for 0% VAT; churches/places can apply for subsidies through the LPOW scheme, and renovations of historic buildings can have part of their tax burden covered through various schemes.
5. Rental and sales flexibility. Castles can be transformed into luxury vacation rentals, wedding venues, or corporate event spaces. Historic buildings serve as scarce resources in high-end target markets, generating strong cash flow.
6. The Window of Opportunity for the British Pound. In 2026, the British pound will offer attractive exchange rates against the US dollar and the Chinese yuan, allowing overseas buyers to acquire higher-value assets at lower costs.
III. Key Costs and Risk Exposures
1. The one-off, high expenditure of the Stamp Duty (SDLT). This is one of the most significant differences from the French system.
Tax rate calculation method applicable to buyer type
UK local buyers (owning only this property) are eligible for standard progressive tax rates of 0%–12%, with progressive rates in segments.
The additional tax rate for overseas buyers (non-residents) is 2%. Buyers who have been in the UK for less than 183 days in the 12 months prior to purchasing the property are considered "overseas buyers".“
For individuals with a second property: Basic tax rate + 5% applies regardless of whether the buyer is a foreign buyer.
Foreign buyer + second home cumulative base tax rate + 2% + 5% = 7% (highest tax rate scenario)
SDLT basic progressive tax rates: £0–£125,000 (0%), £125k–£250k (2%), £250k–£925k (5%), £925k–£1.5m (10%), and above £1.5m (12%).
For example, if a non-UK resident overseas buyer already owns a residential property and then purchases a £2.5 million London castle, they will be subject to a basic progressive tax (approximately £118,750) + a non-resident surcharge (2%) + a second home surcharge (5%), totaling approximately £293,750 in stamp duty (nearly £300,000), which is almost three times more stamp duty than a UK first-time homebuyer.
2. Annual Tax on Property Purchased Through a Company (ATED). If property is held through a company (this is typically considered by high-net-worth investors for tax planning or privacy protection):
Property value range for 2025/26 ATED tax amount
£500,000 – £1,000,000 £3,700
£1m – £2m £7,500
£2m – £5m £25,800
£5m – £10m £61,500
£10m – £20m £124,100
£20m and above £248,350
The ATED tax rate increases every April, leading to a continuous rise in long-term holding costs. Therefore, it is necessary to rigorously assess whether a corporate holding structure is worthwhile.
3. Annual holding and council tax and maintenance costs. Council tax is approximately £900–£3,000 per year (approximately 0.05%–0.4% of the current property price). Castle-style properties typically fall into the higher tier due to their size and land area. Annual routine maintenance costs for British castles (gardening, cleaning, minor repairs, etc.) are approximately £150,000 to £300,000. Heating costs (especially for castle-style properties in the rural areas outside London) are £40,000+ per year, and electricity costs are £60,000+. Major repairs to historic buildings, such as the roof alone, can easily exceed £2 million+, and the total investment may far exceed the budget.
4. Inheritance Tax (IHT) Exposure. The UK IHT exemption is £325,000 per person (2025/26). Amounts exceeding this are taxed at the 40% rate (property must be included in the total estate value). If charitable donations to the estate exceed 10% of the total estate value, the tax rate can be reduced from 40% to 36%. If the beneficiaries are not close relatives (spouse, children, grandchildren) or other family members, the tax rate will be significantly higher; it is advisable to consider setting up a trust or planning the gifting timeline in advance.
5. Loan approval is more difficult. The loan-to-value ratio for overseas buyers is generally 70%–80%, with a down payment of 30%–40%; LTV and income requirements are stricter than for UK residents, and mortgage loan approval processes are longer.
6. Urban planning and historic building protection constraints – this is the unique high barrier to entry for buying a castle in London. Any structural changes require approval from the local planning authorities, and for Grade I, Grade II*, and Grade II protected buildings, repairs, expansions, renovations, and even demolitions are strictly limited. These historic building protection requirements make it extremely easy to exceed budget and timelines.

Application Process & Advice
suggestion
I. Understanding the actual supply of "London Castle" and re-examining demand objectives
For the type of demand, we recommend selecting the expected budget.
Seeking a London castle experience: Apartments within castle grounds (such as those in Vanbrugh Castle) £2.5 million – £4 million
Looking for unique historic residences (not fixated on the word "castle") Grade II Historic buildings, old schools/churches/warehouses converted from £1 million – £3 million
Owning an entire castle but residing in a home county outside London (Surrey/Kent/Berkshire, etc.) priced between £1.5 million and £6 million.
Castles as pure investment and tax-saving tools; country estates (Northern England/Wales' outer suburbs) £300,000–£800,000 (but renovation costs are high).
Grade II, a first-time buyer of historic British buildings, has already renovated a historic mansion, eliminating the need for an immediate large-scale renovation costing £700,000–£1,500,000.
II. Complete team formation before launching the search.
Must-have characters:
• Experienced UK Conveyancing Solicitor: Handles contracts, government searches, and verification of the source of funds, which must be completed before the exchange of contracts.
• Chartered Surveyor: Level 3 Building Survey + Heritage specialist is essential for you.
• Independent Financial Adviser: Specializing in income tax, capital gains tax and inheritance tax structuring for non-UK residents, and assisting in choosing the best structure for personal or corporate property holdings.
Foreign Exchange Specialist: Locking in exchange rates is crucial. A fluctuation of 3% in the CNY/GBP exchange rate over an 8–12 week trading period could incur an additional cost of £75,000 for a £2.5 million property. A reliable FX platform can lock in the exchange rate before authorizing a loan, ensuring your budget remains under control.
III. Contact a loan advisor in advance
• Mortgage rates for overseas buyers will fall to their lowest point in four years in 2026 – approximately 3.951 TP3T–4.301 TP3T for owner-occupied residential properties and approximately 4.751 TP3T–5.501 TP3T for rental investments, with few restrictions.
• You still need to obtain a valid Mortgage Agreement in Principle in advance to ensure that the seller and other bidders will regard you as a serious buyer when you make an offer.
For mortgage loans on historic buildings, more lenders are requiring more comprehensive cost estimates for renovation and maintenance, and a Surveyor report must be obtained simultaneously to proceed with the review process.
IV. Advance Planning for Municipal Taxes and Inheritance Tax
A comprehensive strategy is needed to address both tax advantages and penalties associated with historic castle buildings.
• Utilize the Conditional Exemption: Verify with cultural heritage experts whether the castle meets HMRC's criteria for recognition—architectural and artistic value, whether it is open to the public, etc. This exemption applies to transfers to trusts, inheritances, and gifts during the lifetime, exempting from IHT and CGT, representing a rare and substantial reduction in estate tax globally.
• Place eligible castles into a Trust and establish a Maintenance Fund for their repair, with the Maintenance Fund enjoying favorable IHT treatment.
• If the castle does not qualify for Conditional Exemption, the seven-year rule applies, gradually reducing the total estate through annual gifts during the beneficiary's lifetime (up to £3,000 per beneficiary per year, plus no restrictions on small gifts).
V. Conduct a pragmatic assessment of annual cash flow and total costs
The core formula is: approximately 110% (purchase price + stamp duty + legal fees, etc.) that can be paid in a lump sum for the purchase price + a reserve of at least 20% of the castle's value for future renovation/repair + current annual income that can cover net operating expenses of £200,000–£300,000 per year.
These hard criteria are crucial for purchasing castles in and around London:
• Council tax (average £2,500/year), building insurance (expensive due to high maintenance costs), property management fees (for castle shared rights), and garden/land management fees are not negligible.
• Castle buildings have significantly higher insurance coverage than ordinary houses – repair costs far exceed reconstruction costs, making it essential to purchase "repair cost insurance".
• Periodic (usually every 5 years) structural inspection fees are charged separately.
VI. Conduct thorough due diligence before submitting a quote.
• Listing Status Significance: The listing level (Grade I, II*, II) directly affects the degree of freedom in renovation and the cost of construction approval. Grade I has the strictest restrictions, requiring the use of original materials and traditional techniques for repairs, resulting in staggering time and costs.
• Energy Efficiency and Maintenance Report: The old castle has low energy efficiency, and the EPC (Energy Performance Certificate) will affect future mortgages and rentals. It is recommended to obtain a Structure Survey in advance (RICS Level 3 recommended) to identify potential major problems with the roof, foundation, drainage, and stone structure. During negotiations, you can request the seller to reduce the price or provide repair subsidies based on this information.
• Easements and environmental considerations: Shared road rights, forestry restrictions, heritage protection zones, and flood risks have long-term impacts on castle value.
Purchase process of London castle
The UK property transaction process differs significantly from that in France: there is no statutory notary system; the buyer and seller each appoint their own lawyers or licensed conveyancers to handle the transaction; both parties can cancel their contracts before the exchange of contracts, but once the contracts are exchanged, they become legally locked, and cancellation will result in the loss of the entire deposit (usually 10%).
Phase 1: Preparation and Funding Arrangements (to be completed before commencement)
• Determine the source of funds and total budget (property price + stamp duty + legal fees + survey fees + renovation reserve ≥ 15% – 30% total property price).
• Obtain in-principle loan approval from Specialist International Mortgage Broker.
• Choose a Conveyancing Solicitor and Chartered Surveyor who are proficient in historic building transactions and familiar with overseas buyer processes.
• Open a UK bank account in advance (not mandatory but strongly recommended) for automatic deductions of council tax and property fees upon completion.
Phase Two: Finding Properties and Making Offers
• Look for castle-like properties through high-end agencies such as Strutt & Parker, Knight Frank, and Savills.
Given the scarcity of castle-level assets in London, setting up dynamic reminders for "Castle" and "Listed Building" on general platforms like Rightmove and Zoopla is the only risk of missing out on speed.
• All offers are not legally binding—until the Exchange of Contracts.
Phase Three: Engaging a Lawyer and Conducting Due Diligence
• Provide the solicitor with proof of identity and source of funds (passport, proof of address, bank statements, and a statement of the source of wealth, which must be certified by a local lawyer or notary public) to avoid delays due to anti-money laundering reviews. All non-English documents must be accompanied by an approved English translation and a notarized copy of the original.
• The seller's lawyer provides a draft contract and title documents.
The buyer's solicitor shall conduct the following checks:
• Historical property rights tracing and registration integrity
• Local government planning and environmental protection (especially for buildings listed as protected sites)
Waterway/drainage rights and easements
• Whether there are unregistered rights or government-mandated purchase orders, etc.
This process is expected to take 4–12 weeks, longer than a standard residential transaction due to the complexity of historical documentation for castle-type properties.
Phase Four: Final Inspection and Contract Review
• Please have a Chartered Surveyor complete the Level 3 Building Survey. If special structural or historical building inspections are required, additional heritage building conservation experts should be assigned to participate.
• The lawyer issues a report on the title, pointing out all risks and proposing modifications.
Overseas buyers need to closely monitor exchange rate fluctuations during this period and control costs by locking in exchange rates with FX brokers in advance.
Phase 5: Contract Exchange – The Most Important Node
• Once all buyer conditions are met, the lawyers for both parties exchange contracts by telephone (each party signs an identical contract and mails/emails it to the other).
• The buyer pays a deposit of 5%–10% (usually 10% for castle-type transactions, negotiable for high-value transactions) to the seller's lawyer's client account.
Once the contracts are exchanged, neither the buyer nor the seller may withdraw—only then is the transaction truly locked in. All upfront payments and investigation costs are non-refundable.
Phase 6: Contract Exchange to Completion – 1–4 weeks
• The buyer will transfer the remaining balance (the remaining purchase price and stamp duty to be paid in installments) to the seller's lawyer's account via bank transfer.
• The seller shall deliver the vacant house and keys on the agreed completion date.
Legally speaking, ownership of the asset has been formally transferred to the buyer.
Phase 7: Registration upon completion
• The buyer's solicitor shall pay the Stamp Duty Land Tax on their behalf (which must be completed within 14 days of completion; late payment will incur penalties).
• After the transaction is completed, the solicitor submits the title transfer documents to HM Land Registry to officially register the ownership in the buyer's name.
• The key documents involved in the entire transaction (the "certificate of registration" for the property rights) will be issued by the Land Registry within a few weeks (or longer for castle cases due to their complexity).
Overall process timeline
Key risks and estimated timeframes for each stage
Budget + Team + Loan Pre-approval 4-8 weeks Foreign Exchange Market Volatility
SouFun+ quotes 2–6 weeks or longer. Castle properties are scarce.
Legal investigation (search + inspection + contract drafting) 4–12 weeks; restrictions on historic titles or protected buildings exceeding expectations.
Final negotiations + contract exchange (1-2 weeks). After contract exchange, there is full risk; neither party can withdraw.
Exchange to completion: 1–4 weeks; seller moves out.
Registration + handover takes 1–3 months (after completion). Land registration is slow.
The total time from the initial offer to the final acquisition of ownership typically ranges from 4–6 months (simple castle apartments) to 12 months (large castle estates).

A reliable FX platform can lock in the exchange rate before authorizing a loan, ensuring your budget remains under control.
III. Contact a loan advisor in advance
• Mortgage rates for overseas buyers will fall to their lowest point in four years in 2026 – approximately 3.951 TP3T–4.301 TP3T for owner-occupied residential properties and approximately 4.751 TP3T–5.501 TP3T for rental investments, with few restrictions.
• You still need to obtain a valid Mortgage Agreement in Principle in advance to ensure that the seller and other bidders will regard you as a serious buyer when you make an offer.

IV. Advance Planning for Municipal Taxes and Inheritance Tax
A comprehensive strategy is needed to address both tax advantages and penalties associated with historic castle buildings.
• Utilize the Conditional Exemption: Verify with cultural heritage experts whether the castle meets HMRC's criteria for recognition—architectural and artistic value, whether it is open to the public, etc. This exemption applies to transfers to trusts, inheritances, and gifts during the lifetime, exempting from IHT and CGT, representing a rare and substantial reduction in estate tax globally.
• Place eligible castles into a Trust and establish a Maintenance Fund for their repair, with the Maintenance Fund enjoying favorable IHT treatment.
• If the castle does not qualify for Conditional Exemption, the seven-year rule applies, gradually reducing the total estate through annual gifts during the beneficiary's lifetime (up to £3,000 per beneficiary per year, plus no restrictions on small gifts).
V. Conduct a pragmatic assessment of annual cash flow and total costs
The core formula is: approximately 110% (purchase price + stamp duty + legal fees, etc.) that can be paid in a lump sum for the purchase price + a reserve of at least 20% of the castle's value for future renovation/repair + current annual income that can cover net operating expenses of £200,000–£300,000 per year.
These hard criteria are crucial for purchasing castles in and around London:
• Council tax (average £2,500/year), building insurance (expensive due to high maintenance costs), property management fees (for castle shared rights), and garden/land management fees are not negligible.
• Castle buildings have significantly higher insurance coverage than ordinary houses – repair costs far exceed reconstruction costs, making it essential to purchase "repair cost insurance".
• Periodic (usually every 5 years) structural inspection fees are charged separately.
VI. Conduct thorough due diligence before submitting a quote.
• Listing Status Significance: The listing level (Grade I, II*, II) directly affects the degree of freedom in renovation and the cost of construction approval. Grade I has the strictest restrictions, requiring the use of original materials and traditional techniques for repairs, resulting in staggering time and costs.
• Energy Efficiency and Maintenance Report: The old castle has low energy efficiency, and the EPC (Energy Performance Certificate) will affect future mortgages and rentals. It is recommended to obtain a Structure Survey in advance (RICS Level 3 recommended) to identify potential major problems with the roof, foundation, drainage, and stone structure. During negotiations, you can request the seller to reduce the price or provide repair subsidies based on this information.
• Easements and environmental considerations: Shared road rights, forestry restrictions, heritage protection zones, and flood risks have long-term impacts on castle value.
Purchase process of London castle
The UK property transaction process differs significantly from that in France: there is no statutory notary system; the buyer and seller each appoint their own lawyers or licensed conveyancers to handle the transaction; both parties can cancel their contracts before the exchange of contracts, but once the contracts are exchanged, they become legally locked, and cancellation will result in the loss of the entire deposit (usually 10%).
Phase 1: Preparation and Funding Arrangements (to be completed before commencement)
• Determine the source of funds and total budget (property price + stamp duty + legal fees + survey fees + renovation reserve ≥ 15% – 30% total property price).
• Obtain in-principle loan approval from Specialist International Mortgage Broker.
• Choose a Conveyancing Solicitor and Chartered Surveyor who are proficient in historic building transactions and familiar with overseas buyer processes.
• Open a UK bank account in advance (not mandatory but strongly recommended) for automatic deductions of council tax and property fees upon completion.
Phase Two: Finding Properties and Making Offers
• Look for castle-like properties through high-end agencies such as Strutt & Parker, Knight Frank, and Savills.
Given the scarcity of castle-level assets in London, setting up dynamic reminders for "Castle" and "Listed Building" on general platforms like Rightmove and Zoopla is the only risk of missing out on speed.
• All offers are not legally binding—until the Exchange of Contracts.
Phase Three: Engaging a Lawyer and Conducting Due Diligence
• Provide the solicitor with proof of identity and source of funds (passport, proof of address, bank statements, and a statement of the source of wealth, which must be certified by a local lawyer or notary public) to avoid delays due to anti-money laundering reviews. All non-English documents must be accompanied by an approved English translation and a notarized copy of the original.
• The seller's lawyer provides a draft contract and title documents.
The buyer's solicitor shall conduct the following checks:
• Historical property rights tracing and registration integrity
• Local government planning and environmental protection (especially for buildings listed as protected sites)
Waterway/drainage rights and easements
• Whether there are unregistered rights or government-mandated purchase orders, etc.
This process is expected to take 4–12 weeks, longer than a standard residential transaction due to the complexity of historical documentation for castle-type properties.
Phase Four: Final Inspection and Contract Review
• Please have a Chartered Surveyor complete the Level 3 Building Survey. If special structural or historical building inspections are required, additional heritage building conservation experts should be assigned to participate.
• The lawyer issues a report on the title, pointing out all risks and proposing modifications.
Overseas buyers need to closely monitor exchange rate fluctuations during this period and control costs by locking in exchange rates with FX brokers in advance.
Phase 5: Contract Exchange – The Most Important Node
• Once all buyer conditions are met, the lawyers for both parties exchange contracts by telephone (each party signs an identical contract and mails/emails it to the other).
• The buyer pays a deposit of 5%–10% (usually 10% for castle-type transactions, negotiable for high-value transactions) to the seller's lawyer's client account.
Once the contracts are exchanged, neither the buyer nor the seller may withdraw—only then is the transaction truly locked in. All upfront payments and investigation costs are non-refundable.
Phase 6: Contract Exchange to Completion – 1–4 weeks
• The buyer will transfer the remaining balance (the remaining purchase price and stamp duty to be paid in installments) to the seller's lawyer's account via bank transfer.
• The seller shall deliver the vacant house and keys on the agreed completion date.
Legally speaking, ownership of the asset has been formally transferred to the buyer.
Phase 7: Registration upon completion
• The buyer's solicitor shall pay the Stamp Duty Land Tax on their behalf (which must be completed within 14 days of completion; late payment will incur penalties).
• After the transaction is completed, the solicitor submits the title transfer documents to HM Land Registry to officially register the ownership in the buyer's name.
• The key documents involved in the entire transaction (the "certificate of registration" for the property rights) will be issued by the Land Registry within a few weeks (or longer for castle cases due to their complexity).
Overall process timeline
Key risks and estimated timeframes for each stage
Budget + Team + Loan Pre-approval 4-8 weeks Foreign Exchange Market Volatility
SouFun+ quotes 2–6 weeks or longer. Castle properties are scarce.
Legal investigation (search + inspection + contract drafting) 4–12 weeks; restrictions on historic titles or protected buildings exceeding expectations.
Final negotiations + contract exchange (1-2 weeks). After contract exchange, there is full risk; neither party can withdraw.
Exchange to completion: 1–4 weeks; seller moves out.
Registration + handover takes 1–3 months (after completion). Land registration is slow.
The total time from the initial offer to the final acquisition of ownership typically ranges from 4–6 months (simple castle apartments) to 12 months (large castle estates).
