I Build Tax-Refund Calculators for Property Purchases

I design and build tax-refund calculators specifically for property purchases — a tool that lets a visitor enter the price of the home and the amount of interest already paid on a mortgage, then instantly see how much tax they can claim back. This is not a generic loan calculator and not a mortgage-comparison widget that ranks banks; it is a focused instrument built around one question a buyer actually asks after closing a deal: how much money comes back from the state.

Working with law firms and realtor agencies, I know the calculation has to respect real limits — capped deduction bases, joint-ownership splits between spouses, separate treatment of principal price versus interest paid, and clear messaging when a user has exceeded the eligible amount. I build the logic in clean, well-commented code so your in-house team can adjust thresholds later without hunting through the whole project, and I hand over the exact formulas used so nothing behaves like a black box.

Every calculator I deliver is mobile-friendly, fast, and easy to drop into an existing page as a self-contained block matching your site's style. I also add clear result explanations next to the numbers, because a bare figure without context rarely turns a visitor into a client.

What's included:
— input fields for property price and interest paid, with validation
— instant calculation of the eligible refund amount
— responsive layout that fits your existing design
— source code and short documentation for your developer
