The analyst on your shoulder
Real estate rewards the investor who can say no to ninety-nine listings quickly and yes to the right one with conviction. Mortar exists to make that screen instant: open a listing, and in the time it takes to read the address, see whether the deal is worth your time — scored against your buy box, with math you can trust.
What we believe
The math is deterministic, not a guess
Cap rate, cash-on-cash, cash flow and GRM are computed by fixed formulas from transparent assumptions — the same way every time. An AI never does the arithmetic. It only estimates rent and value when the listing doesn't publish its own, and we label it when it does.
Local accuracy beats national averages
A blanket 1.2% tax assumption makes deals in Texas, Florida and New Jersey look like winners that actually bleed every month. We use real per-state property tax and insurance so the verdict is right in the markets you actually buy in.
An analyst, not an advisor
Mortar hands you a fast, honest read so you can decide. It is not financial advice, not an appraisal, and not a recommendation. Every number is an estimate to verify before you make an offer — and we say so, plainly, everywhere.
We will never fabricate proof
No invented reviews, no fake testimonials, no inflated numbers to make a deal — or the product — look better than it is. If you see a quote on this site, a real person said it and gave us permission to share it.
How we make money — and what we do with your data
Mortar is funded the simple, honest way: by subscriptions. Five analyses a month are free, forever. Investors who make it part of their workflow pay for Pro or Operator. Payments are handled entirely by LemonSqueezy — your card details never touch our servers.
We do not sell your data, show ads, or track your browsing. The extension only runs on the Zillow listing page you choose to analyze. We are not affiliated with Zillow. The full details are in our privacy policy.
Who's behind it
Mortar is built by a small, independent team that got tired of copying listing prices into spreadsheets to answer one question: is this deal worth my time? We built the tool we wanted — fast, honest, and in-context on the listing — and we're shipping it in the open. Have a property the analyzer mis-read, or an idea for what it should do next?
