Notes
- 4.5× income is the standard FCA/PRA cap. Lenders can lend 15% of new loans above 4.5×, so a small number stretch to 5–5.5× for high earners.
- LTV bands typically price at 60%, 75%, 80%, 85%, 90% and 95%. Crossing a band down can save 0.3–0.6% on the rate.
- Stress test: most lenders assume rate = product rate + 1% for affordability.
- This is an estimate. Speak to an FCA-authorised broker for a decision in principle.

Is a £50,000 mortgage affordable?
Lenders typically cap borrowing at 4.5 times household income, so a £50,000 mortgage usually needs an income around £11,111 plus a deposit on top.
- Check the payment at a rate 1–2 points higher than today's — that is your renewal risk.
- A larger deposit moves you into a cheaper loan to value band and cuts the monthly cost.
