Mortgage intelligence

Stage 3 of 7

Choosing a mortgage

Compare the cost and flexibility of mortgage deals, including fixed periods, fees, monthly payment pressure, and follow-on rates.

What this stage means

This stage is about choosing between mortgage products once the property budget and upfront costs are broadly understood.

A mortgage with the lowest headline rate is not always the lowest-cost or best-fitting option once fees, term, fix length, flexibility, and future plans are included.

Key numbers to understand

  • Initial rate, fixed or tracker period, and the standard variable or follow-on rate after the deal ends.
  • Product fees, valuation fees, broker fees, cashback, and whether fees are paid upfront or added to the loan.
  • Monthly repayment during the deal, total paid during the comparison period, and balance remaining.
  • Overpayment allowance, early repayment charge period, and any portability rules.

Common mistakes

  • Choosing only by rate without comparing fees and remaining balance.
  • Adding fees to the loan without noticing the extra interest over time.
  • Ignoring whether the deal length matches likely life events, moving plans, or remortgage timing.

How to interpret the result

Compare both monthly affordability and total cost. A deal can be cheaper overall but still uncomfortable month to month.

If results are close, flexibility, ERC terms, fee payment method, and remortgage timing may matter more than a small cost difference.
