High Value Mortgages
“Bigger loans deserve a sharper approach.”
Borrowing a large amount is rarely just a bigger version of a normal mortgage. Lenders look closer, ask more questions and price things differently. We know which lenders are comfortable at your level.
Quick answer
A high value mortgage usually means borrowing around £1 million or more, though some lenders treat loans from £500,000 differently. Cases are underwritten by a person rather than a computer, which can open up higher income multiples, interest only and private banks. The main thing to know is that maximum loan to value often falls as the loan size rises.
How high value lending works
At this level an underwriter reviews your whole situation: salary, bonuses, share schemes, investments and future plans.
That opens up income multiples above 4.5 times, bonus income counted more generously, interest only or part and part repayment, and private banks that lend on wider wealth.
We compare mainstream lenders, specialist lenders and private banks side by side, then package the case so the underwriter has the answers before they ask.
Interest only and part and part
Interest only keeps payments down but needs a credible plan to repay, such as investments, pensions or sale of another property.
Part and part splits the loan so some is repaid and some is interest only, which many lenders prefer at this level.
Eligibility and what lenders assess
Who may qualify
High earners and those with significant assets buying or remortgaging £1 million or more.
Deposit and LTV
Often 15% to 25%, with lower LTVs for the largest loans.
Income and affordability
All income sources considered, including bonuses and dividends.
Credit history
Clean history expected by mainstream and private banks.
Property requirements
Unique or high value homes may need specialist valuations.
Common reasons for decline
Income that can’t be evidenced, or a repayment plan that doesn’t stack up.

Costs, risks and when it may not be suitable
Being upfront about this is part of doing it properly.
Costs to budget for
- Product and arrangement fees
- Valuation and legal costs
- Early repayment charges if you leave a deal early
- The total cost of borrowing over the full term, not just the initial rate
- A longer term lowers monthly payments but increases the total interest you pay
Risks to weigh up
- Private bank offers can depend on moving assets to them
- Interest only leaves the full balance to repay
- Your home may be repossessed if you do not keep up repayments on your mortgage
When it may not be suitable
- If your income is simple PAYE, a mainstream lender may be cheaper than a private bank
- If you can’t evidence a repayment strategy, interest only won’t be available
What you will need
The exact list depends on your lender, but this is what to start gathering.
