UK Property Deal Finder — ROI, Cashflow & Payback on Every Listing

Most property scrapers hand you listings. This one hands you deals — every property already scored for ROI, monthly cashflow, payback period and the better strategy (buy-to-let vs serviced accommodation), ranked best-first.

Set your filters, hit Run, get a spreadsheet of what's actually worth viewing.

What makes a "deal"

Each row is a public listing — Rightmove, ImmobilienScout24, or a live UK auction lot — run through standard investor maths (75% LTV, interest-only, purchase and operating costs) against real local rent comps for that postcode.

Field	What it tells you
roiPct	Annual cash-on-cash return on the money you put in
cashflowMonthly	What lands in your account each month after mortgage and costs
paybackMonths	How long until your cash comes back out
cashInvested	Deposit + fees (+ furnishing for serviced accommodation)
strategy	btl (long let) or r2sa (short let) — whichever returns more
rentConfidence	Whether the rent behind that ROI is from real comps or an estimate
condition	AI read of the listing photos: refurbished / cosmetic / project
listingSource	portal or auction (with auction house + auction date)
url	Straight to the listing

Why the extra fields matter

rentConfidence — an ROI is only as good as the rent behind it. confident means the median of 8+ real rental listings at the same outcode and bedroom count. directional means 3+ real comps. estimate is a fallback and can flatter the numbers. Filter to comps-backed when the figures need to hold up.

condition — a vision pass over the listing photos separates let-ready stock from cosmetic refreshes from full projects, so a refurb hunter can shortlist in one query. It is deliberately not a refurb-cost estimate: damp, wiring and roofs don't show up in photographs.

Auction lots — auction stock is where a lot of the return lives, and it's priced off a guide. A guide is a marketing bracket, not a price; lots routinely sell well above it. Treat any auction ROI as a ceiling, never an expectation. Guide-priced lots are flagged as such, and implausible ones are filtered out of the default feed.

Honest limits

• Rents are modelled per outcode (and per bedroom count where comps allow), not per individual property.
• Scoring is as-is: no refurb uplift, no refinance. A BRRR deal's real return comes from work this model can't see.
• Auction guides are brackets, not prices.
• Figures are indicative estimates for shortlisting, not financial advice. Verify anything before you buy it.

Coverage

UK (Rightmove + live auction lots) and Germany (ImmobilienScout24), across ~1,700 postcode areas, refreshed on a schedule — auction stock daily, since lots expire fast.
