Help Analyzing a Deal

[Christina Merlo]

I have a STR that I'm looking to buy out of state. It was listed for 100k I offered 75k he countered with no lower than 90, I offered 85 and he said 87.5k. my partner thinks if I stay firm at 85 he will accept but I'm afraid to lose the deal. Do I risk it for $2500 or just accept and sign. My rough calculations are negligible but he doesn't want me to leave money on the table. I'm not sure what to do.
Also, first time analyzing a STR, do these numbers look ok (the 15k rehab is rolled into the loan)
