How do you get a mortgage over £500,000 or £1 million?

Large mortgages (over £500,000-£1 million) require specialist lenders or private banks who understand high-value properties and complex income. Unlike standard mortgages limited to 4-4.5x income, specialist lenders offer 5-6x income multiples for high earners and certain professions. They assess your total wealth, not just salary, and provide bespoke underwriting. You'll typically need a 20-25% deposit, excellent credit, and may need to demonstrate bonus income, investments, or multiple income streams to qualify.

What Are Large Mortgages?

Large mortgages (sometimes called jumbo mortgages) are home loans exceeding the limits of standard high street lenders—typically over £500,000-£1,000,000. They require specialist lenders who understand high-value properties, complex income structures, and high-net-worth individuals.

Unlike mainstream mortgages with standardised criteria and automated underwriting, large mortgages involve bespoke assessment of your total financial picture. Specialist lenders consider your overall wealth, not just salary, and can offer higher income multiples (5-6x instead of 4-4.5x) for high earners and certain professions.

Whether you're buying a premium property, need to borrow over £1 million, have complex income from multiple sources, or are purchasing a unique high-value property, we have access to private banks and specialist lenders who can help. We'll navigate the complexity to secure the right large mortgage for your circumstances.

Your home may be repossessed if you do not keep up repayments on your mortgage.

Large Mortgage Guide: Expert Tips

Essential knowledge for high-value property finance

How Much Can You Borrow?

Standard lenders typically offer 4-4.5x income, but specialist lenders go to 5-6x for high earners, certain professions (doctors, lawyers, accountants), or with significant assets. Some lenders consider total wealth, not just income. On a £150,000 salary, you might borrow £600,000-£900,000 depending on the lender. Joint applications multiply this. We know which lenders offer the highest multiples for your profession and circumstances.

Income Assessment for High Earners

High earners often have complex income—base salary, bonuses, dividends, investments, rental income, overseas income. Specialist lenders understand this complexity and assess your full financial picture, not just basic salary. They'll consider guaranteed bonuses, average bonuses over 2-3 years, and sustainable income streams. Company directors can use retained profits. We present your income in the best light to maximise borrowing.

Property Valuation Considerations

High-value and unique properties require specialist valuers who understand the premium market. Standard automated valuations don't work for properties over £1-2 million or unique/period properties. Lenders use RICS valuers experienced with premium properties. Location matters hugely—prime London postcodes valued differently than equivalent properties elsewhere. Be prepared for conservative valuations and have evidence of comparable sales ready.

Deposit Requirements

Large mortgages often require smaller LTV percentages. While you might get 90-95% LTV on a £200,000 property, expect 75-85% max on properties over £1 million. On a £2 million property, you'd typically need £300,000-£500,000 deposit (15-25%). However, the LTV requirement can mean lower interest rates. Some private banks offer better terms for clients with significant overall wealth even if the property LTV is high.

Private Banks vs High Street Lenders

High street lenders have maximum loan amounts (often £500,000-£1,000,000). For larger mortgages, private banks and specialist lenders step in. They offer bespoke service, flexible criteria, and consider overall wealth relationship. Interest rates may be higher, but they'll lend amounts and on properties mainstream lenders won't touch. They're also more flexible with income assessment and international clients.

Documentation Requirements

Large mortgage applications require comprehensive documentation: 2-3 years' tax returns, SA302s, accountant references, proof of deposits/assets, explanation of wealth sources, sometimes credit reports from multiple agencies. International income needs translation and verification. The more complex your finances, the more documentation required. Being organised and transparent speeds up the process significantly. Professional presentation of your financial position is crucial.
