## Large mortgage loans

A large mortgage loan is a mortgage that exceeds the maximum loan size offered by most mainstream lenders, typically requiring a specialist large loan team or a private bank. Large mortgages are assessed with greater flexibility than standard residential loans, because the borrower’s wider wealth, liquidity, and asset base can be taken into account alongside income.

## Private bank mortgages

Private banks are a core source of high net worth mortgage lending in the United Kingdom, particularly for large mortgage loans, complex income, and internationally connected borrowers. Private bank mortgages are individually underwritten, and terms are negotiated case by case rather than drawn from a fixed product range.

## Expat and foreign national high net worth mortgages

High net worth mortgages are available to British expats and foreign nationals purchasing or refinancing UK property, subject to lender criteria on residency, visa status, and source of funds. International HNW cases are typically served by private banks and specialist lenders with international underwriting capability.

## Working with a high net worth mortgage broker

## Interest-only high net worth mortgages

Interest-only borrowing is widely available to high net worth borrowers, because lenders can rely on credible repayment strategies such as investment portfolios, sale of other assets, business sale proceeds, or future liquidity events. An interest-only high net worth mortgage keeps monthly payments lower and preserves capital for investment elsewhere.

## High net worth mortgages for complex income

Many high net worth borrowers have income that does not fit standard affordability models, such as substantial discretionary bonuses, partnership profit shares, carried interest, vested and unvested stock awards, dividends from personal companies, or income drawn from trusts.

## High net worth mortgages through companies and trusts

High net worth borrowers frequently hold or purchase property through limited companies, limited liability partnerships (LLPs), or trust structures, whether for privacy, succession planning, or tax reasons agreed with their professional advisers.
