Features & Capabilities

Mortar is a real estate deal analyzer. Open any listing on Zillow, Redfin, Realtor.com, or Homes.com and Mortar reads the numbers off the page (price, taxes, rent estimates) and shows you whether the deal actually works.

It computes the numbers investors care about: cap rate, cash-on-cash return, monthly cash flow, and a plain BUY / INVESTIGATE / PASS verdict. Every figure shows its math, using localized property-tax and insurance rates so the result reflects the state the property is in, not a national average.

The free trial gives you three analyses, no account needed. You can adjust the assumptions behind every calculation (down payment, interest rate, loan term) and watch the verdict update live.

Note: on Firefox, Mortar currently runs as the free anonymous trial. Account features like saved deals, history, and higher limits are available on Chrome and Edge while full Firefox account support is in progress. The core analysis works the same on all browsers.

Is Mortar: Real Estate Deal Analyzer Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Mortar: Real Estate Deal Analyzer requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Mortar: Real Estate Deal Analyzer is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
