Official statistical benchmark + rule-based calculation · not a lending decision
Can we afford to buy in Lisburn and Castlereagh?
The area’s official average price and residents’ median pay first, then plain arithmetic for your household: deposit, loan, monthly repayment at a rate you choose, and the multiple of your gross income the loan would be. Lenders apply their own tests; none is modelled here.

£1,267 a month
Deposit £24,074 · loan £216,663 · 6.2 times gross household pay of £35,000
That is 53% of net household pay of £2,393 a month under the 2026/27 rules. The 5% rate is a placeholder you should replace with a real quote: no official average mortgage rate is loaded on this site. Repayment mortgage, fixed rate for the whole term, no fees, no stamp duty.
