What to check before relying on the estimate

Consider pension income, retirement spending and long-term affordability.

When an adviser review may help

A mortgage adviser or broker partner can compare your circumstances with lender criteria and explain any fees before you decide whether to proceed. This website provides general information and calculator tools; it provides general information only and does not make regulated mortgage recommendations.

Keep the estimate realistic

Use current balances, evidenced income, realistic property values and cautious rate assumptions. If a result looks affordable only under one optimistic assumption, run a second scenario before making plans.
