If I put in the post rehab income in, the planning amounts in the report generated with the BRRRR tool are artificially inflated. 

well, who stands to benefit from inflated appraisals?

The odds of the seller giving you a dollar for dollar reduction on every item that came up on your inspection report is slim and a lot of these things are issues they will claim you could plainly see during your initial property tour/walkthrough. 

Ensure that you aren’t inflating the ARV or underestimating repairs just to make the deal work.  3.  

Hi Charlie,If you intend to rent it to "Trendy's" who can afford to move elsewhere it would be smart to discuss (a lot of) noise and smell abatement with your architect.If you intend to rent it to the more shall we say, "Down and Out types" it would still be smart to discuss noise and smell abatement.Noise from frequent commercial trash pickup, odd hours deliveries, commercial bus service noise, as well as inter-unit from the commercial spaces and each other, etc....Good Luck!

Most areas in PA and other states are privatized, and therefore non-lienable.In your case, it's an 'odd' case, so I'm really not sure. 

As someone who has done hundreds of these deals, I must say I find it odd that the owner is demanding this. 

Check with DOT for any road widening that might take some of your land and reduce down the amount of parking spaces available.Make sure newly signed rent for that box building size is not inflated for the area where the seller in exchange for TI's is getting inflated rents to sell off to a buyer.

Even odds they will still be there next month and now you are two months short on rent. 

Also, a couple of what I feel are critical features are having the 'inflation rates' for income, expenses, and property values.
