FAQs
Can I buy credits?
We do not allow any Exchange members to purchase credits and not participate in our comp trading system. In our view, whenever we allow users to purchase credits, that is a concession that affects the foundation of our system and our ability to consistently populate our database. To find out how you can receive more credits, click here.
Can I search for specific property types?
Yes! You can specify property types under the Space Type filter. Select the overarching space type (office, industrial, retail, etc) and then select the checkbox to search within the property subtype. Apply the property subtypes where applicable. If you're unable to find exactly what you're looking for, write to us at help@compstak.com for more help!

How do you have my deal?

Deals are traded throughout the CRE community every day. We encourage you to share any deals, especially your own, as soon as possible to ensure you get the most credits possible.
How do you know submitters aren't giving you false information?
To ensure each comp in our database is the most accurate and complete transaction record available, CompStak utilizes machine learning, analyst review, and community regulation to verify our lease and sales information. Check out this article to read more in-depth about our process.
How does CompStak make money?
Working in tandem with CompStak Exchange, CompStak Enterprise is available on a subscription basis exclusively to qualified entities operating in the commercial real estate space. Companies including financial institutions, private equity funds, owner/operators, REITs, advisors, and more can pay to access CompStak’s data via platform access, custom APIs, and/or custom data feeds.
How long will it take for the credits to appear in my account after submitting comps?
Once a comp is entered into our system, our team will enter that into our processing queue as soon as possible. We strive to process all comps within a few days of submission but certain types of comps and formats do take longer to process. We will send you an email with your credit reward once your submission has finished processing.
If you'd like to check on the status of your submission, you can do so by clicking on your initials in the top right and then choosing Credits from the drop-down menu. There will be the status of all of your past submissions and the credits they have earned.

What to do if I think/know the info in this comp is wrong?
While CompStak's top priority is the quality and accuracy of our data, there are times when our data is incomplete or incorrect at the time of reporting.

Our state is a non-disclosure state, how does that impact the comps I can obtain access to?
In disclosure states, we seed our database with publicly recorded information in addition to our crowd-sourced comps. In non-disclosure states, our database will not be seeded with that publicly recorded data so the only data we have in those states is our crowd-sourced comp data. With that lack of public information, it emphasizes the need for a service like CompStak in the CRE community.
How do I refer a colleague to CompStak Exchange?
You can refer a colleague to earn bonus credits by going to the bottom of your Dashboard and selecting Refer Your Colleague. You will need to provide your colleague's contact information in order to get those credits, and you can refer an unlimited amount of users. Once your colleague has activated their account, the credits will be added to your account. For more information, click here.
What does sharing 1 comp get me?
In exchange for the comps you share, you will earn anywhere from 1-30 credits. Once they are added to your account, you can use those credits however you would like. That means unlocking just one comp or multiple comps - whatever is most helpful to you!
What if I need credits but don't have comps to share right now?
If you’re in a bind and need some credits, email help@compstak.com or call us at 646-926-6707, and we’ll be happy to help. We’re sure you’ll return the favor when you get a chance!
Where can I find my submissions?
