Development Appraisal

Pro feature — free during beta

Model acquisition, build, finance, and sale assumptions to assess development viability.

Assumptions

SDLT uses 2025/26 residential bands plus the 3% additional property surcharge.
Finance uses simple bridging interest against the borrowed purchase amount based on monthly rate, term, and LTV.
Viability compares gross profit margin to your target: at/above target is viable, within 5 percentage points below is marginal, lower than that is unviable.
Outputs are indicative planning figures and not formal tax, legal, lending, or investment advice.
