We have since had renovation crews in to add 2br/1ba in the attic, which our anticipated appraisal after construction came back very favorable to the investment, due to it improving it's functionality and improving it's comparables zone.  

Much of it is from lenders trying to refi to terms that do not favor us but get them paid a few points for restructuring our debt.We are not doctors, lawyers, or any other professional that justifies this debt.

Glad to hear the deal worked out in your favor.

So if I state in the agreement that seller will pay up to 6% concessions, is there a way that I can structure it in an incremental fashion.

Some companies have favorable financing options. 

I would keep track and carry over my losses to a more favorable year that can offset a gain you have.  

Sorry for the shameless plug however I never returned the favor and perhaps this can help.

When you have a average joe six pack type of job, your debt to income ratios are not in favor or additional borrowing power. 

So if your owners were not in favor of your rental cap, someone could investigate how many votes were collected to pass that amendment and then argue that the judgement in this case supports retracting the amendment and putting it out for re-vote. 

It has been my experience when providing breaks for people it doesn't work in my favor.
