If I Earn £X, What House Price Can I Afford?

One of the first questions for any first-time buyer is how much home you can realistically afford. The answer often depends on whether you qualify for a standard mortgage or an income stretch product. 

The multiplier guide: standard vs stretch 

Most lenders use a multiplier of your annual income as a starting point. While 4.5x remains the high-street standard, many first-time buyers – particularly those with a 5% or 10% deposit – can now access 5.5x or even 6x their income through schemes like Nationwide’s Helping Hand or Lloyds’ FTB Boost. 

Here’s how those numbers look when you add a 10% deposit: 

*Note: 6x multiples typically require a minimum income (often £30,000 for individuals or £50,000 for joint applicants) and a clean credit history. Professional roles (solicitors, doctors, etc.) may access even higher multiples.

Beyond the multiplier: your true affordability 

Lenders don’t just look at your salary – they look at your free income. Your total budget may be adjusted downwards if you have high committed expenditure, such as: 

• Significant student loan or car finance repayments 

• High monthly childcare costs 

• Large outstanding credit card balances 

Lenders now use Open Banking to see your real-time spending habits. Showing a couple of months of sensible spending before you apply can actually improve your borrowing power.

Factor in the tax landscape 

Remember that your affordability also depends on the tax you’ll pay. In England, first-time buyer relief currently applies to properties up to £300,000. If you use a stretch budget to buy a home for £350,000, you’ll need to budget for Stamp Duty (SDLT) on the portion above £300,000. 

In Wales, Land Transaction Tax (LTT) applies instead. There’s no specific first-time buyer relief, but the 0% threshold for all residential buyers is currently £225,000.
