Why TAG
Landlords know they will make more money dealing directly with you rather than a tenant broker. We will not let that happen.
We know the market and are experts at negotiating better terms during lease renewals. Let us secure you a new and improved deal.
Under Illinois law the licensee you work with is presumed to be your designated agent — unless a written agreement says otherwise, or they are only performing ministerial acts (225 ILCS 454/15-10). Putting your representation in writing is what makes that protection real. TAG will go to bat for your business.
Space types
The advantage

Our strong rapport with building agents means we can quickly deliver the best deal terms.
Our large deal flow helps us understand the current market and what owners are willing to provide their tenants.

We also got nine months free on a seven-year extension where the landlord was giving other tenants less than a month per year. According to the leasing agent, it was by far the most aggressive deal the current owners have completed in the building. I’m so grateful f…”
“I feel extremely confident in saying that for the ultimate space I chose, Bill and Diana secured me a fantastic deal. I will be paying a below market rate for the area, receiving 6 months of free rent on a 6 and a 1/2 year term, and on top of that I will be getting a beautiful turnkey space built out to my ideal specifications. Bill and Diana are a pleasure to work with and are extremely responsive and communicative. They made me feel as if I was their mos…”
