House hacking - home needing repairs, seller not willing to do all of them

[Jesus Bravo]

Hey all,

Im new to the forum but exited to join and gain/share value from experiences. 

Im currently under contract for my 2nd house hacking property. The inspections were completed and turns out that a good amount of the work done in the house by the seller to flip the property was done poorly. If the major defects (bad window installment, clogged piping, pool transformer) are fixed, I could deal with the rest of defects and fix them myslef (bad valves in bathroom, placement of air handler, undersized water heater). Point being, to me it still seems like a good deal to close on this property as I could cashflow about 800-1000 bucks per months so if I was left to repair those things (assuming 12-15k in rework) ROI would be about a year or so. What are people's thoughts?
