UK property analytics

Know what a deal is worth before you spend a Saturday driving to it.

PropertyDealSource appraises a UK property against twenty investment strategies and shows you the numbers, the assumptions behind them, the risks that could break them, and the tax you would actually pay. All on one screen.

Capabilities

What it does

Six things an appraisal has to answer before the number at the bottom means anything.

Twenty strategies, scored honestly

BTL, HMO, serviced accommodation, rent-to-rent, social housing, supported living, commercial conversion, land, auction and historic. Each scored for this property, with the reasoning shown, and the ones that do not apply marked not applicable rather than quietly omitted.

Red flags before you view

Knotweed, cladding, subsidence indicators, short lease, flying freehold, Article 4, mundic block, coastal erosion. Probabilistic flags carry a confidence level and a source, so you can tell a certainty from a suspicion.

Tax modelled, not hand-waved

SDLT, LBTT and LTT with the right band table for the right country. Section 24, corporation tax with marginal relief, CGT stacked on your income, and a personal-versus-company comparison reporting both retained and extracted profit.

Demand you can check

Rental demand built from multiple signals with the coverage ratio stated. Where the data is thin we say so, rather than presenting a confident-looking score built on a single source.

Deliverability, not just yield

A deal no lender will fund and no builder will price is not a deal. Mortgageability, refurbishment risk and contractor availability are scored alongside the return.

Stress tests as standard

Every projection shows what happens when rates rise, the refurbishment overruns, voids extend or the exit price slips. The scenario that breaks the deal is marked.

House rules

How we present numbers

Property is an industry with a long history of confident spreadsheets. These are the rules we hold ourselves to.

Ranges, not false precision
A modelled figure is presented as a range with its assumptions listed. A single confident number implies a certainty the underlying data cannot support.
The denominator is always stated
Yield on what — purchase price, total project cost, or cash invested? Three different numbers, three different arguments. We label which one you are looking at.
No guarantees, ever
We model outcomes. We do not promise them, and you will not find the words “assured” or “risk-free” anywhere on this platform.
