Hey everyone — I built Propty.uk because I was tired of running property deals through messy spreadsheets that broke every time SDLT rates changed. I'm a UK property investor and I kept hitting the same problem: every calculator online was either too basic (just gross yield), too generic (US-focused), or locked behind a paywall before you could even see if it worked. So I built what I actually needed — a full suite of tools that reflect how UK property deals actually work. Mortgage stress testing at real lender criteria, SDLT with the 5% surcharge, Section 24 tax impact, HMO room-by-room yields, renovation specs with cost estimates, cashflow projections over 30 years and loads more. There are 17 tools in total and most are completely free — no signup, no credit card, just open it and run your numbers. I'd love to hear what you think — especially if you're a UK landlord or investor. What tools are missing? What would make this more useful?
