Problem statement
Many investors struggle with manual spreadsheets, scattered data, and listings that move faster than they can analyze.
Deals gone before you decide
By the time you've run the numbers, someone else has made the offer.
No signal, just noise
Zillow gives you price and photos. Not whether the deal actually works.
Solution · Process
Mortar gives you the answer,
not the inputs.
Skip the spreadsheet. Mortar reads the listing, pulls the numbers, estimates rent, and delivers a verdict the moment you click, so you can decide before the deal disappears.

haaris.africawala@gmail.comHow Mortar Works
When a listing shows Zillow's Rent Zestimate, Mortar uses that. When it doesn't, Mortar falls back to an AI estimate based on the property's size, location, and details. You can always edit the rent to your own number.
