Exploring the Costs of a £10 Million Mortgage
A £10,000,000 mortgage is a major financial undertaking that requires careful planning and a clear understanding of the costs involved. Whether you’re a high-net-worth individual, an investor, or simply researching mortgage options, this guide will provide insights into the key factors influencing your borrowing. At Kerr & Watson, we specialise in bespoke mortgage solutions, ensuring that you receive expert advice tailored to your financial needs.
Factors That Influence the Cost of a £10 Million Mortgage
Interest Rates
The interest rate on a mortgage significantly impacts monthly payments. Generally, lower interest rates reduce costs, but the rate you receive will depend on the lender, the mortgage type, and your financial profile. Some private banks may offer preferential rates for loans of £10 million or more. These mortgages are highly bespoke, making it essential to work with an adviser who can compare lenders and secure the most competitive deal.
Loan-to-Value (LTV) Ratio
Lenders determine mortgage terms based on the loan-to-value (LTV) ratio, which compares the loan amount to the property value. A higher deposit usually results in lower interest rates. For a £10 million mortgage, securing an LTV between 60% and 70% can provide more attractive terms, while an LTV of 85% or higher may come with additional costs or stricter requirements.
Mortgage Term
The repayment term affects both monthly affordability and the total cost of the loan. A longer term lowers monthly payments but increases the overall interest paid. Most lenders offer terms between 15 and 30 years, with a preference for full repayment by age 75. However, requirements vary, so it’s important to seek professional guidance.

Estimated Monthly Repayments
To illustrate how different interest rates and mortgage terms affect monthly payments, here are some examples:
Example 1: 25-Year Term at 4% Interest
- Monthly Payment: ~£52,780
- Total Repayment: £15,834,000
Example 2: 25-Year Term at 5% Interest
- Monthly Payment: ~£58,460
- Total Repayment: £17,538,000
Example 3: 30-Year Term at 4% Interest
- Monthly Payment: ~£47,740
- Total Repayment: £17,191,200
These calculations are based on capital and interest repayments. However, an interest-only mortgage can significantly lower monthly outgoings. For example, a £10 million mortgage at 4% interest on an interest-only basis would cost approximately £33,333 per month, compared to £52,780 with a repayment mortgage.

Deposit Requirements
The deposit required for a £10 million mortgage varies by lender, but here are some common scenarios:
- 10% Deposit (£1,000,000): Higher borrowing amount, leading to increased monthly repayments.
- 20% Deposit (£2,000,000): More favourable terms and lower monthly costs.
- 40% Deposit (£4,000,000): Access to the best rates and reduced overall borrowing costs.
Additional Costs and Fees
Arrangement Fees
Most lenders charge arrangement fees, either as a fixed amount (£10,000–£20,000) or as a percentage of the loan. A 1% arrangement fee on a £10 million mortgage would be £100,000.
Valuation and Legal Fees
Valuation costs typically range from £1,000 to £4,000, while legal fees vary depending on the complexity of the mortgage, generally between £2,000 and £5,000. Your mortgage adviser can help source quotes from surveyors and solicitors.
Income and Eligibility Requirements
Lenders require a strong financial profile for high-value mortgages. Typically, a household income of around £2,000,000 is expected, but affordability also depends on financial commitments such as school fees, existing debts, and lifestyle expenses.
For borrowers with complex income structures, additional documentation may be required, including:
- Bonus or commission earnings
- Foreign currency income
- Business or self-employed profits
- Dividends or investment income
- Trust fund distributions
A mortgage adviser can assess your finances and guide you through the necessary documentation to maximise your borrowing potential.
