Stresst: Mortgage Calculator

Stresst runs the property maths that usually lives in four browser tabs and a spreadsheet. Mortgage payments, buy-to-let yield, overpayments, remortgage and rate-switch break-even, stamp duty - calculated properly, in seconds, on your phone. Then the deeper investment tools: cash flow, ROI, cap rate, BRRRR, HMO, and what a flip actually nets once every real cost is counted. Built for property investors, landlords, and the brokers and agents who work alongside them. Stresst does not generate leads, sell your details, or route you to a broker or a lender. It is a calculator. That is the whole product. KNOW YOUR NUMBERS BEFORE YOU COMMIT Most deals get modelled in the version where everything holds - the rate, the tenant, the timeline. Stresst lets you check the other versions. What a rate rise does to the payment. What a void month does to the yield. How far rates would have to fall for a shorter fixed rate to have been worth taking. It shows you what would need to happen. It does not predict what will.

IMPORTANT Stresst is a calculator and planning tool. Results are indicative only and depend entirely on the figures you enter. It is not financial, tax, mortgage or investment advice, and it does not recommend products, lenders or rates. Tax and lending rules change - always confirm with a qualified professional before committing to anything.
