Tenant Rep Deal - Looking for thoughts and feedback.

My client and I have been in negotiations since Oct. on a space for his restaurant space. Originally, $40/psf base on 1,700sf space for 10 years. In the latest iteration the LL wants us to take on an additional 973sf so the remaining sf would be marketable for another.

I was able to get them to take 50% off the additional space in year one and then 25% in year 2. After alls said and done the total concession value (abatement,construction period,TI,discounted rent,etc) we are looking at almost 20% of base lease value. Which I think is pretty amazing for my client.

Do other brokers track and present this information to their clients? Mine was over the moon and has never had concessions presented like this.
