REO Occupied Duplex Help

[William Henze]

This property would be a total shot in the dark but has huge potential to be a great flip and also a decent cash flow property. Current asking price is $27K, however I'm sure that I could get it for less. I estimate the ARV to be in the $80K-$90K range. No pictures of the inside are available and no walkthroughs or inspections are permitted as it is occupied and being sold "as is". With no way to estimate the rehab costs, that's what makes this a shot in the dark, but I think I could be "all in" for around 60k IF there is no structural issues. Does anyone have experience in PA getting an occupant out? How expensive is that process and how long would it take? Thank you in advance for your opinions and advice!
