Timeline

Calculations based on 2026/27 HMRC rates and ONS house price data (March 2026). Stamp Duty calculated using current SDLT/LBTT/LTT rates. Mortgage calculations assume a 25-year repayment mortgage. Mortgage borrowing limits are estimated at 4.5x salary — some lenders may offer up to 5x or 5.5x depending on your circumstances. Actual borrowing capacity depends on your credit score, outgoings, employment status, and individual lender criteria. All figures are estimates only and do not constitute financial advice. Always consult a qualified mortgage adviser before making property decisions.

Mortgage calculations are estimates only. Actual affordability depends on credit score, lender criteria, and individual circumstances. Stamp duty rates from April 2025. House prices are ONS averages and may not reflect current market conditions.
