Buying a home is one of the biggest financial commitments you’ll make. Before you start house hunting, the first question is: “How much can I borrow for a mortgage?” The answer depends on your income, deposit, credit history, and outgoings. In this guide, we’ll explain how lenders calculate borrowing power, what affects it, and how Everest Mortgages can help you maximise a responsible figure.
How do lenders calculate mortgage borrowing?
Most lenders start with income multiples and then run detailed affordability checks. Typical ranges are 4.0–4.5× annual income, sometimes 5–5.5× for certain professions or very strong profiles.
Example: Salary £40,000 × 4.5 = £180,000 potential borrowing.
But this is only a guideline. Lenders stress‑test against higher rates and examine outgoings to ensure repayments remain affordable.
Key factors affecting how much you can borrow
• Income: basic pay plus (depending on lender) overtime, bonus, commission, and self‑employed profits.
• Outgoings: loans, credit cards, car finance, childcare, student loans, and other mortgages.
• Credit history: strong credit can boost your options; missed payments or adverse credit can restrict borrowing.
• Deposit & LTV: larger deposits reduce risk for lenders and can improve available multiples.
• Product & borrower type: first‑time buyer, home mover, self‑employed, contractor, or BTL each have different rules.
Mortgage borrowing examples
• Single applicant: £35,000 income × 4.5 = ~£157,500.
• Couple: £30,000 + £25,000 = £55,000 × 4.5 = ~£247,500.
• High‑earner with bonus: £70,000 basic + £20,000 bonus. Depending on lender treatment of variable pay, borrowing could be 5–5.5×.
Tools to estimate borrowing power
Online calculators give quick estimates but rarely capture nuances (variable income, dependants, benefits, or complex credit). A broker can run lender‑specific calculators to provide a more accurate figure and identify lenders most generous for your profile.
Common mistakes
1) Ignoring debts and commitments. 2) Assuming all lenders treat bonuses/overtime the same. 3) Relying only on income multiples without stress‑testing. 4) Forgetting that childcare and dependants reduce affordability.
Why use a mortgage broker?
A whole‑of‑market broker like Everest Mortgages compares affordability models across lenders, knows who’s flexible with income types, and can present your case correctly. That can mean higher borrowing and smoother approval.
