Obviously, removing the body is going be one of the first things to get done.  

I feel like regular units would decrease my cash flow. 

Any body have luck with Facebook?

Even in a regular market the market can change dramatically (for or against you) in the 60+ days it takes you to list and sell a property.Assessing risk-reward ratios, to each his own.  

I recommend speaking with a lender who works with local investors regularly.

Any appliance connected to a two prong outlet would be floating and create a serious shock hazard since the only path to ground would be through the body of anybody touching that appliance.

You can also get way better deals from regular seller on Craigslist or OfferUp/Facebook...But a shop with warranty is little less risky if you aren't personally inspecting the unit.

No body likes when they are asked for money.

So my advice is to make sure you factor those costs in and make sure you allocate at least 10-15% of your cashflow each month for maintenance and keep up with it.There is a local meetup the first Wednesday of each month that has about 100 regular attendees. 

Many regular agents would not know how to handle this without asking their broker..I assume you contacted the seller after the listing expired, correct?
