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.
