If the projections do not substantiate the purchase price, you may want to renegotiate to make it work better for you (making your money on the buy of course).Good luck! 

It sounds like it's time for renegotiation!

If the POS inspection has yet to be done, there's the opportunity to renegotiate with the seller if you are to assume the violations, especially if costly exterior violations like driveway or sidewalk. 

i asked the bank for a line of credit to change the and upgrade the exterior then I started working on the interiors as the tenants would move, then Hurricane Ida took the roof off 4 years ago completely rebuilt took the opportunity to renegotiate leases and increased cash flow What was the outcome?

Get the inspection report or do your own and then re-negotiate it if you don't feel comfortable based on the results.

Communication is in some sort of halt at the time as I told them I will not even discuss renegotiating any terms of the contract until they bring their payments to date, as I take that as bad faith.

If it is substantially larger that might be worth backing out over, but usually it's simply worth renegotiating. 

The 60-day close is likely a tactic to tie up your property, then renegotiate once you've lost valuable market time.

The lease agreement may include terms for renegotiating the lease usually at either set intervals or upon expiration.   

Im going to renegotiate with seller,  using the uninsured lot as the reason, because the heir issue is always a risk.
