Getting started
Windows may show a SmartScreen warning because this independent build is not code-signed. Only continue if you downloaded it from this page.
Starter example data is included. New listings are stored in a local SQLite database under your Windows user profile, so each user on the computer has an independent workspace.
%LOCALAPPDATA%\RentSeer\rentseer.db
Bring your own RentCast API key to retrieve fresh listing data. Use it for the current session or save it in Windows Credential Manager. RentSeer does not include a shared developer key.
RentCast usage limits and charges remain your responsibility.
RentSeer is an analysis tool, not financial advice. Verify listing data and assumptions independently before making an investment decision.
