About Us



CompStak is a free resource for brokers, appraisers, and researchers to access thousands of office, industrial, and retail lease comps.  


What is CompStak?

CompStak is a comp trading platform that operates on a one for one model: if you give a lease comp, you can get a lease comp. CompStak makes information sharing and comp trading easy.

Thousands of brokers, appraisers, and researchers share the lease comps they have to get the lease comps they need.

It’s 100% free and 100% anonymous.

The Broker List members who sign up for CompStak receive 10 comps before having to submit their own data.

"The idea of crowd sourced comps is genius. We all need comps and it makes sense that if I contribute to the community I get to use the community. I am eager to have our 2 sites working together to solve this much needed gap in our industry! Thanks Compstak for doing this for the greater good of CRE."
"If you are in commercial real estate you know that comps are our lifeblood. We need to know our markets and CompStak offers a free platform that only requires your participation, but no cash! How cool is that? It is what technology can do today for all of us. It is called crowd sourcing and you need to contribute to the community to get back from the community. Super easy!"

With the platform put in please by COMPSTAK providing accurate information in exchange for accurate comps is great. I have spoken with the CEO of this company and he is great as well. Must use tool for CRE professionals."
