Enter the key numbers — the engine works out the most you can offer with SDLT, legals, refurb and contingency all in, while staying under your cash cap.
The Key Numbers
Everything recalculates live as you type.
End value = what the property will sell for on that street once it's done up — not what you pay for it. Back it with sold comps below.
Comparables — End Value Check
Add 3–5 recent sold comps. Median £/sqft × your sqft = evidence-backed end value.
Refurb Budget Builder
SPA master price list (2025/26). Set quantities, push the total into your refurb budget.
