What is the planning probability?
LPA approval rate, recent appeal patterns, policy fit, design-officer signal.
/ 03
Which finance structure fits?
Senior debt, mezzanine, JV equity — matched to GDV and the developer's track record.
/ Who this is for
Built for the operators who actually have to decide.
Owner-managed UK property developers, self-build investors and small-scale landlords-going-into-development — running schemes of 1-50 units who carry the viability and planning risk personally.

/ FAQ · before you ask
What people ask before they use PropSnap.
01 Is the viability number lender-grade? +
Indicative. Final viability needs a chartered QS and an RICS Red Book valuation. PropSnap gets you to the right number to start the conversation.
02 Does it cover commercial-to-residential conversions? +
Yes — Permitted Development rights (Class MA, Class AA, Class O) are dedicated tracks.
03 Will it handle Section 106 and Community Infrastructure Levy? +
Yes — both are surfaced against the local authority's published rates.
04 Is the planning probability legally meaningful? +
No — only a planning officer's decision is. The probability is a screen based on LPA approval patterns, design-officer signals and policy fit.
