RentScope Pro is the paid companion to the free RentScope calculator. It runs as a single self-contained HTML file — open it in any modern browser, offline, with no account and no server. Your inputs never leave your computer.
Where the free calculator shows pre-tax cash flow and returns, Pro adds the analysis investors use to compare real deals: after-tax cash flow, depreciation and recapture, capital-gains tax on exit, sensitivity tables and a full 30-year projection.
The store link is coming soon. In the meantime the free calculator is fully usable.

FAQ
Do I need Excel or Google Sheets?
No. RentScope Pro is a single self-contained HTML file that runs offline in any modern browser. There is nothing to install and no account to create.
Is my data uploaded?
No. Everything runs locally in your browser. Your inputs never leave your computer.
Does it handle short-term rentals?
The cash-flow and return math is the same for short- and long-term rentals — enter the revenue and expense assumptions that match your strategy.
Can I use it for commercial property?
It models single-property cash flow, financing and after-tax returns. Commercial deals often need additional assumptions (leases, tenant improvements, capex schedules) that are outside this model.
Do I get updates?
Yes. Free updates to the same download — re-download from your purchase receipt.
