Hey Caleb, I currently do BRRRR deals in Akron. Below are a few steps I would take:
1) On the % ARV question, Purchase price = (ARV*LTV Refi) -All Expenses (Rehab, holding cost, closing cost, etc). For LTV Refi, I typically use 75%. For you analysis, the actual loan amount with an ARV of $115k and LTV of 75% will be $86.25k. You will plug that into the refinance loan amount instead of the $115k. When you rerun the numbers, you purchase price is going to be lower than $65k.
2) A few notes from the pictures: Basement looks wet ($5-10k to fix), water heater looks older ($900), roof repair ($1200), cosmetic updates ($15-$20k). Assuming the bones of the property are good (Electrical, plumbing, HVAC).
3) Make an offer based on your BRRRR analysis contingent on inspection. During this inspection period, have a property inspection and get actual contractor quote.
4) Adjust offer price or move forward with existing contract.
Good Luck,
Blair
