Analyse any buy-to-let in seconds: yields, cashflow and the post-tax truth
A deal that looks good on gross yield can lose money after tax and a rate rise. The Buy-to-Let Deal Analyser stress-tests it before you offer.
Enter the price, refurb, mortgage and rent and the analyser returns gross and net yield, monthly cashflow, total cash in and cash-on-cash return — with stamp duty calculated automatically from the purchase price and the 5% additional-property surcharge.
Where it goes further than a spreadsheet is the stress test and the post-tax view: it shows what happens to your cashflow if interest rates jump, and it compares your post-tax return as a sole trader (under Section 24) versus in a Ltd Co, for both the 2026/27 and 2027/28 tax years.
That means you see the deal the way it will actually perform — not the flattering gross number that ignores tax, voids and rate risk.
Who it's for: anyone about to make an offer on a hold-and-let property who wants a one-page verdict they can trust.
