A lease comp, or comparable, is a complete record of a lease transaction that has taken place.

Our comps contain information like tenant name, address, rent, square footage, landlord concessions, broker names, and more.

NYC: We have nearly 100% of the commercial office deals complete in Manhattan in the past year and over 50% of commercial deals completed in the past 10 years.

CompStak is only open to professionals in the commercial real estate community like brokers, appraisers and researchers.

We approve most requests in 24 hours. Please check your email spam filter. If you still haven't received an email, please contact us: info@compstak.com.

CompStak is only available to real estate professionals.

We know how important brokers and other real estate professionals are to get deals done, and our goal is to make their lives easier and help the market work more efficiently.

CompStak is free (for a basic membership). Commercial real estate brokers, appraisers and researchers are eligible for a free membership, and may simply provide the comps they have to find the comps they need.

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 sales@compstak.com.

Right now, no. Our top priority is building a comprehensive database for our members.

1. We use advanced machine learning to test the data we receive.
2. Every comp submitted is reviewed by a CompStak analyst.
3. We receive most comps several times. Every time we receive a comp is a new opportunity to validate the information received.
4. 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.

In these cases, the member that submitted that comp will lose points. After multiple offenses we will suspend the account.

If you want CompStak to come to your market, let us know: info@compstak.com.

• 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 12-20 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.

After you email your comps to comps@compstak.com, we quickly reply acknowledging the receipt of 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.

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.

If a member submits comps that are later updated by another member or a CompStak analyst they will lose points for those attributes.

Currently no. In the future we plan to offer reports which brokers can brand with company logos.

To see all the comps you own, simply click on "My Comps" at the top of the screen.

Absolutely. We understand that although you want to share information, you may prefer to do it privately, and this is why we won't tell anyone you're a CompStak member unless you want us to.

We won't even tell others in your company!

When we add your comps, other members will see your username – not your identifying information. That's why we recommend that you select a username that cannot be traced back to your real identity.

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.

Each member is required to have an individual account.

• Tenant Name
• Address
• Floor
• Space Type
• Transaction Size
• Transaction Date
• Starting Rent
• Escalations in $ or %

You receive extra point for every piece of information beyond these required fields.

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.

You will be provided with access to every comp you submit without having to use points to buy them.

Out of respect for our members privacy, we don't share their names or company names. We normally have representatives from most of the brokerage and appraisal firms in a given market.

Not necessarily! We will accept any lease comp, but please do not send anything you are not allowed to share.
