Compare mortgage decisions

Change one variable at a time before comparing choices

Scenario Lab is designed to make the consequence of a changed input visible. Compare payment, interest, balance, and cash requirements against the same baseline rather than treating a single scenario as a recommendation.

Tradeoffs to weigh

A lower rate may require more upfront cost; a shorter term may reduce modeled interest but raise payment; and a larger down payment can lower borrowing while reducing liquid cash. The important tradeoff depends on the inputs you hold constant.

What the model assumes

Each scenario is a fixed-rate model using its selected country convention and entered costs. It does not evaluate credit, property valuation, lender pricing, taxes, legal costs, or eligibility.

Checks before relying on it

Name the real decision, keep comparable inputs aligned, and save the lender documents you use to replace estimates. Review the methodology and country convention before comparing scenarios across markets.
