Calculator outputs are estimates only. They do not confirm lender acceptance, product availability, rates, fees or suitability.

This page is written as a calculator companion: use it to choose sensible inputs, compare scenarios and understand the limits of an estimate.

What to check before relying on the estimate

Prepare contract details, day rate, renewal history and company accounts where relevant.
Avoid assuming all lenders will treat contractor income in the same way.
Use the estimate to frame a broker conversation, not as an approval decision.

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.
