Sagging floor

[Allen Grant]

I am trying to crunch numbers on my first deal. A fix and flip using a hard money lender. Its a HUD home for 25K. Its a 1300 square foot 2 story built in 1930. When pulling comps, I am estimating the ARV around 60-70K. The home already has newer vinyl siding, newer windows, and a new roof. It has a nice attached two car garage. My biggest holdbacks are that the entire middle of the house (floor) is sagging. Not a lot, but its noticeable. I will also have to replace the furnace/water heater. It also only has one bath that will need completely remodeled. The loan will cost me 3,200 for a six month hold (if I happen to be stuck with it that long). Any input is greatly appreciated as again, this is will be my first deal. Thanks in advance!
