£250,000 at a 5% deposit
A £250,000 home with a 5% deposit of £12,500 means borrowing £237,500 — 95% loan-to-value. At around 4.5× income that needs roughly £52,800 of household income; at 5×, about £47,500. Lenders assess affordability individually, so the multiple is a starting point rather than the answer. On a purchase at this price a first-time buyer in England or Northern Ireland would pay no stamp duty.
