Questions

FAQ

Quick answers about comps, data sources, and reports

What is a comp in commercial real estate?

A comp (short for comparable) is a recent sale or lease of a property similar to yours. Brokers, lenders, and appraisers use comps to estimate what a property is worth or what rent it can command.

How much does a comp report cost?

Nothing. Reports are free and there is no subscription. We only ask for your contact details when you export a report, so we can follow up about your property and market.

Where does the data come from?

Every search runs live against public listings, property records, and brokerage announcements, and every comp is labeled by source: Verified (submitted by a local broker and reviewed by our team), Public record, Listing, News, or Estimate, so you always know how much weight to give it.

Can I find out what my building is worth?

Yes. Enter your address and property type. We pull the building's square footage from public records automatically (you can override it), and every report opens with an estimated value range based on recent comparable sales. Add NOI for an income-approach cross-check. It's an automated estimate, not an appraisal. For a real opinion of value we'll connect you with a licensed local broker, free.

What property types are covered?

Industrial, office, retail, multifamily, land, and residential. Industrial reports also include building specs such as clear height and dock doors.

How accurate are the reports?

Comps are a starting point, not an appraisal. The data comes from public sources and can contain errors, so verify anything important before relying on it. For a true opinion of value, talk to a licensed local broker. Reach out and we can connect you with one.
