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.

Specialist HNW lenders and private banks can assess complex income on its underlying substance. For example, a lender may take a multi-year average of bonus income, recognise vesting schedules for stock awards, or assess retained profits within a company the borrower controls, subject to the lender’s individual criteria.

Presenting complex income correctly is one of the most important parts of a high net worth mortgage application. Clear evidence, such as remuneration statements, partnership accounts, vesting schedules, and trust documentation, allows the lender to give full weight to the borrower’s true earnings.

Frequently asked questions

Can I get a high net worth mortgage with bonus, carried interest, or stock income?

Yes, specialist lenders and private banks can assess bonus income, carried interest, vested stock, dividends, and partnership profits. Lenders may average variable income over several years or recognise vesting schedules. Clear documentation of each income source is essential to achieving full recognition in the affordability assessment.

What is a high net worth mortgage?

A high net worth mortgage is a mortgage for borrowers with substantial income or assets, assessed on overall wealth rather than standard income multiples alone. High net worth (HNW) mortgages are commonly used for large loans, interest-only borrowing, and complex income, and are offered by specialist lenders and private banks.

Do private banks offer the best high net worth mortgages?

Private banks offer flexible, individually negotiated high net worth mortgages, but they are not always the most competitive option. Some require assets under management (AUM) as a lending condition, which affects true cost. Comparing private banks against mainstream large loan desks and specialist lenders is essential.

Can I get a high net worth mortgage through a company or trust?

Yes, high net worth mortgages can be arranged for limited companies, limited liability partnerships (LLPs), and trusts, subject to lender acceptance of the structure. Lenders typically require personal guarantees from beneficial owners, and offshore structures reduce the available lender pool, making whole-of-market advice important.

How long does a high net worth mortgage take to arrange?

Timescales vary with case complexity, lender type, and documentation. Straightforward large loans can progress on similar timescales to standard mortgages, while private bank lending, trust structures, or international borrowers can take longer due to enhanced due diligence. Early preparation of documents shortens the process.
