Borrowing £180,000 at 4x income supports a property of about £200,000 with a 10% deposit of £20,000. Lenders check the monthly payment against your spending too, not just the multiple — at about £1,000 a month the payment sits near a third of a typical £45,000 take-home, which is inside most affordability models.
Monthly payments on £180,000 over 25 years: £950 at 4%, £1,000 at 4.5%, £1,052 at 5%. A bigger deposit moves you to a lower LTV band and cheaper rates. The MoneyHelper mortgage calculator is the official independent tool for checking affordability on gov-backed guidance.
What lenders actually check on a £45,000 salary
On £45,000 the check that decides the outcome is the debt-to-income ratio, read in the round: committed debts against gross salary, with most lenders comfortable below roughly 35–40% and sharp-pencil about anything above. The income itself gets its quality review — guaranteed components count in full, bonuses and commission need the twelve-month pattern, and a recent promotion counts only from the payslips that prove it. Lenders at this level also read the bank statements for stability signals: steady saving toward a deposit strengthens the file; large unexplained transfers or revolving overdraft use weaken it. Qualified professionals (medicine, law, accountancy, teaching and similar) unlock profession-specific lending at some banks — higher multiples against the same salary, priced on career trajectory — and a £45,000 file with clean credit and documented earnings is exactly the profile those schemes were designed for.
£45,000: the professional band, read like a lender
£45,000 produces a band of £180,000–£202,500, and at this level the binding constraint is rarely the multiple — it is the affordability stress test. Lenders model rates several points above today’s and ask whether the payment still clears the budget after childcare, commuting and committed debts. The professional-band playbook follows from that: cut committed spending before applying, not after; keep the credit utilisation low on every card; and time the application away from big new commitments. Two structural advantages also arrive at this income — eligibility for professional/profession-specific lending where offered, and a debt-to-income position strong enough that most high-street lenders quote from the top of the band rather than the middle.
