🏠 Work Out What Someone Can Borrow

I work with buyers and the first thing everyone asks is what they can afford. Build me an affordability calculator for a public page. The visitor enters household income, deposit, monthly commitments and dependants. Work out an indicative borrowing range using an income multiple and an interest rate that I keep as editable settings rather than fixed numbers, and show both figures on screen so nothing is hidden. Also show a stress-tested figure at a higher rate that I set. Display the estimated monthly payment for the middle of the range. Put a clear, plain-English notice on the page saying this is an estimate for guidance and not a decision, an offer, or financial advice. Ask for a name and email only after showing the result, and save each calculation as an enquiry. Add an AI agent that explains which single input would change their range the most and by roughly how much. Automate emailing the visitor their result and a scheduled weekly digest of enquiries to me. Two logins: an adviser who sees enquiries, and an owner who sets the rates and multiples.
