The bank listed for 299k ... A comparable property around the area is list at about 350k.
That's completely meaningless, as it's not even selling for the 299 it's listed for. What does it actually comp out at?
If this was a deal, it would have been snatched up. How long has it been on the market? It sounds overpriced to me.
Clearly less than 300k, minus the 30k in repairs, doesn't seem to be worth the 275 you bid just based on value.
Now looking at rents, $1200/unit = $2400 gross on 300k+ (with repairs) is a pretty poor ROI. When you consider those repairs will be cash (can't leverage it at low rates), the ROI looks even worse.
I wouldn't buy that as an investment property. Probably wouldn't pay more than about $185k in good shape, $150k as it is. That clearly isn't possible in some locations, but that's one reason I asked about the actual comps, above.
Since you're looking to live there, however, you'll have to evaluate it versus your other options. It may be better to get this place and have a poor ROI than rent. It may not.
How much do you want to be landlords?
Some things to think about.
