Decision workflow

Confirm effective date, residential status, linked transactions, relief, replacement of main residence, company/trust status, lease rules and refund eligibility with the relevant authority or adviser.

Documents to collect

Keep the latest contract, quote, statement, policy schedule, official threshold or disclosure that supports each input. Record its date, jurisdiction and whether the amount is before or after tax, fees, deductible, inflation or other adjustments.

Compare like with like

Hold the decision horizon and scope constant. Change one assumption at a time, retain the base and adverse scenarios, and explain why a result changes before treating it as useful.

When to stop and verify

Stop when policy language, tax status, legal eligibility, underwriting, a live rate, an official valuation or a professional judgment determines the outcome. Residential freehold/simple consideration scenarios only. It excludes mixed/non-residential property, leases, shared ownership, multiple dwellings, linked purchases, corporate special rules and relief calculations. Rules checked 2026-10-08.
