A few percentage points on LTV, rate or tax can change what you pay by thousands of pounds. Running the numbers early helps you set a realistic budget and compare deals properly.

Tips for UK readers

• Stamp duty rules differ by nation: SDLT in England and Northern Ireland, LBTT in Scotland and LTT in Wales.
• Lenders price mortgages in LTV bands, so a slightly bigger deposit can unlock a noticeably lower rate.
• Always compare the total cost of a mortgage deal including fees, not just the headline rate.
• Most lenders let you overpay up to 10% of the balance each year without early repayment charges.
