For example if you don't live close to a gas public utility you ll be looking at all electric appliances from what I understand they are cheap but expensive to maintenance.

I would seek out local realtors, property management companies, local newspaper and local real estate publications.

A simple example may be just owning two LLCs, one purchases the note, forecloses and sells it to the other LLC for basically the value on the note and there's no need to be sneaky about it either especially as a real estate broker I can list properties on the MLS all day long and make it a "public" sale. 

In some municipalities in my area, the sale of a property comes with a requirement to connect to public sewer.

Again, i'm not saying a group of people can't buy foreclosures by bidding at auction and, i'm not saying that they can't turn around and sell it right after, I'm saying that one needs to be careful as it relates to bidding at public auction.
