Does CompStak give or sell comps to tenants?

Enterprise customers like real estate private equity funds, banks, asset managers, REITs and hedge funds can pay for access to our data. For more information, please contact email@example.com.
Can I buy individual comps?
Right now, no. Our top priority is building a comprehensive database for our members.
How do you ensure comp data quality?
- We use advanced machine learning to test the data we receive.
- Every comp submitted is reviewed by a CompStak analyst, and cross checked with CRE professionals like, the broker that completed the transaction, the landlord of the building where the transaction took place, or a CompStak member from the same firm that completed the deal.
- We receive each comp an average of 7 times. Every comp we receive is a new opportunity to validate the information received.
- All of our members have the opportunity to flag comps that appear incorrect, comment on the issues, and even suggest updates to every field in a comp.
What happens if a member intentionally contributes bad data?
In these cases, the member that submitted that comp will lose points. After multiple offenses we will suspend the account.
When are you coming to my market?
How do I earn points?
- Adding Comps – If you are the first member to submit a comp that is approved, you will receive full points for that comp. You earn 1 point for each attribute of a lease. Most comps are worth between 12-25 points. You are not limited to sending only your own deals, but please do not send anything you're not allowed to share.
- Updating Comps – If you see a comp on CompStak that has incorrect or missing information, you can suggest updates or additions to individual comp attributes.
- Earning Royalties – CompStak members receive a 20% royalty on every comp they contribute that is also approved.
How do I add comps?
To add comps, simply click “Add Comps” at the top of the page. From there you may choose to upload PDF or XLS documents with comps in them, copy and paste a single comp, or email your comps to firstname.lastname@example.org.
How will I know that you've received my comps?
After we receive your comps via the CompStak website or via email we quickly reply acknowledging the receipt of the comps. Processing your file(s) and crediting your account then takes us anywhere from several hours to a day. When the process is complete we send you a second email notifying you that your account was credited.
How do I spend points?
You can use points that you’ve earned to buy the comps you need. Each comp on CompStak is worth a number of points equal to the number of attributes available in the comp.
How do I lose points?
If a member submits comps that are later updated by another member or a CompStak analyst they will lose points for those attributes.
Can I create comp reports?
Currently, no. In the future we plan to offer reports, which brokers can brand with company logos.
How can I view the comps I have purchased or contributed?
To see all the comps you own, simply click on "My Comps" at the top of the screen.
Why should I choose a username that does not reveal my real identity?
When you add comps, other members will see your username – not your identifying information. We understand that although you want to share information, you may prefer to do it privately. CompStak does not share the names of our members unless you want us to.
I'm out of points. But I need a comp. What can I do?
Can you send us some comps? We will accept any lease comp you are allowed to share and credit your account with points. In case you're wondering, we do not sell points/comps. Our top priority is building a comprehensive database. If we allow members to buy comps it may discourage them from contributing.
I have 4 appraisers on my team. Can we each have an account?
Each member is required to have an individual account. We’re working on a new product for teams. If you’d like more info, please give us a call – 646.926.6707.
What information is required for a comp?
- Tenant Name
- Space Type
- Transaction Size
- Execution Date
- Starting Rent
- Escalations in $ or %
You will receive one point for each of these attributes as well as every comp attribute beyond these required fields.
How can I find the specific comps I need before buying?
You can filter search results and sort by many attributes such as transaction size, date, and space type. Once filtered and sorted, your list of comps will show the address, tenant name and transaction quarter. The rest of the comp information will only be visible after you purchase the comp.
Do I need to buy comps that I contribute?
You are automatically provided with access to every comp you submit without having to use points to buy those comps.
Which brokers, appraisers and companies use CompStak?
Out of respect for our members’ privacy, we don't share member names or company names. We normally have representatives from most of the brokerage and appraisal firms in each market we cover.
Do I have to send you only my own deals?
Not necessarily! We will accept any lease comp, but please do not send anything you are not allowed to share.
