High-earning professionals and business owners rarely have income that fits a standard payslip. Bonuses, restricted stock units, carried interest, dividends and rental income can all be part of the picture, but how they are treated varies widely between lenders.
The Bank of England held Bank Rate at 3.75% at its September 2026 meeting, by a 6–3 vote with three members preferring a rise to 4%, and the next decision is due on 5 November 2026. With CPI inflation at 3.1% in the 12 months to August, borrowers should not assume rates will fall soon.
Why complex income is assessed differently
High street lenders often cap how much variable income they will count, sometimes using only a portion of bonus or a short average. Private banks and specialist lenders usually take a more holistic view, looking at overall wealth, assets under management and history of earnings, not only the latest payslip.
Common income types and how they are viewed
- Bonuses: typically assessed over two to three years of history; some lenders count 100% of a consistent bonus, others a fraction.
- RSUs and share awards: may be counted when vested and evidenced by statements, but unvested awards are treated cautiously.
- Dividends and director’s income: assessed from company accounts, tax calculations (SA302s) and retained profit, as covered in our guide to mortgages for the self-employed and company directors.
- Investment and rental income: usually accepted with evidence of continuity and tax paid.
Asset-based lending
Where income is irregular, some private banks lend against assets, pledging an investment portfolio or holding deposits with the bank. This can allow larger loans or interest-only structures, but it exposes assets to market movements and margin calls. Our overview of private bank high-net-worth mortgage lending explains these structures.
Presenting your case
- Gather three years of tax returns, accounts and bonus statements.
- Prepare a statement of assets and liabilities.
- Explain any one-off or declining income openly.
- Choose a lender based on how it treats your specific income, not just headline rate.
Regulation and affordability
Residential mortgages remain regulated, so lenders must still assess affordability, even for wealthy borrowers. Interest-only borrowing requires a credible repayment strategy. With Bank Rate unchanged at 3.75% and the Bank’s committee split, stress-tested payments remain an important constraint on how much can be borrowed.
Tax treatment of bonuses, share awards and structures is complex; speak to a qualified tax adviser or accountant. Our residential mortgage hub collects related guidance, and our Putney office works with many professional clients in south-west London.
Frequently asked questions
Can unvested shares count as income?
Generally not. Lenders may count vested shares that have actually been sold or paid, but treat unvested awards as uncertain, so evidence matters.
Do private banks always lend more?
Not always. They may be more flexible on income structure, but typically want a wider relationship, such as deposits or investments, and their pricing reflects that.
Is interest-only available for high earners?
Yes, but lenders require a credible repayment strategy and sufficient assets, such as a portfolio or a defined sale of the property. Strategies are reviewed periodically.
How long should I allow for a complex case?
Allow extra time for document gathering, accountants’ letters and valuations on higher-value properties. Early engagement with a broker helps avoid delay.
