The Ultimate Guide to Concession Data Available on CompStak

March 05 - 2021

How do you usually go about gathering information on concession data?

If you’re like most, you likely often call upon other brokers and appraisers in your network to figure it out. But in the ever changing landscape of the CRE industry, it takes a lot of time to collect enough data points to confidently navigate through all these varying concession trends.

Here’s how you can find accurate concession data more quickly and more easily with CompStak Exchange.


Types of concession data you can find on CompStak

With CompStak Exchange, you can access averages for free rent and TI allowance values, net effective rent, starting rates, and other comp details in any market, submarket, or a custom property set. You can also analyze market performance and a space’s potential by looking at concession averages.

To start, let’s take a look at an example of a comp with complete concession data:

Comp with complete concession data


Free Rent (Abated Rent)

The majority of our lease comps include the free rent provision. When you’re looking at comps on CompStak, it’s important to note that if the Free Rent value says “0m” this means that the deal did NOT include a free rent period. If we don’t know whether or not the deal included free rent, we leave this field BLANK.

TI/Work Allowance

Most of our lease comps also contain the terms of the Tenant Improvement Allowance agreement (sometimes referred to as TI, TIA, or TA). Just like with Free Rent concessions, we don’t display a value in the comp’s TI fields if we don’t have any firm information on a deal’s TI Allowance clause, and instead leave it BLANK. If our research shows that the tenant did NOT receive a Tenant Improvement Allowance as part of the deal, we will record it as: “$0

Concession Notes

This particular type of concession data is the most unique to CompStak. Concession Notes like the below are collected directly from our members (oftentimes, from someone directly party to the deal) and contain a level of detail that a simple numerical value can’t provide.

Delayed Commencement

At the end of 2020, the CompStak Data Science Team discovered an interesting trend. In 2020, the median number of days between lease execution and commencement dates for office space increased by a full month, to 126 days nationwide. This is more than one month longer than the average over the prior 5 years.

Landlords understand that if they don't sign the prospective tenant now, they may have to wait awhile for another opportunity to fill the space. Meanwhile, tenants realize that they won't have employees in the space any time soon, but they want to lock in the deal today. The best solution for both parties is to sign now and delay commencement. While the space may be vacant for an additional few months, this still benefits the landlord as the delayed commencement doesn’t decrease the net effective rent.

What if the comp you’re interested in doesn’t include concession terms?

You can still get the data you need by looking at other comps in the same building or in competitive buildings nearby. Most of these comps will have concession data, so you’ll still be able to make a fair assessment of current concession trends.
