Most investors spend 30–45 minutes in a spreadsheet before they can assess a single deal. DealFlow does it instantly — yield, SDLT, cash flow and an AI verdict, all in one place.
Built by a RICS Registered Valuer. The metrics are right.

Save deals, compare them side by side, and get an AI plain-English verdict on each one.
No spreadsheet. No £500/month software. No guesswork.
Gross yield, net yield, and net initial yield (NIY) — the metric professional valuers actually use — all calculated instantly. Adjust void allowance, management fees, maintenance and mortgage rate with live sliders.
Buy-to-let surcharge, first-time buyer relief, commercial rates, VAT on fees — every variation of Stamp Duty Land Tax handled automatically and broken down band by band.

A plain-English verdict grounded in your actual numbers — not generic advice. Covers deal quality, cash flow position, and the single biggest risk or opportunity. What a valuer would tell you over coffee.
