You won't be able to sell it to yourself, and a bank won't lend to a new LLC  unless the owner signs as personally liable anyway. 

Depends on the documents you sign.

I was a week away from closing on a great place in Decatur city limits near downtown, but I couldn't get the HOA lady to communicate with us before we purchased, which was a bad sign and I walked.

Depends on the specific auction as well as the contract you sign once you win the bid - the terms vary based on the bank, the state you're in, the property, etc.

When the total number of jobs is 637,000, this is only a small drop in the bucket, but it is a positive sign that you would look for in a market.If you create a spreadsheet like the one above yourself, you can literally put in any data points that matter most to you and compare from there.  

Whether you can pick your own title company depends on the specific auction/bank/property/state you're in - make sure that you read the fine print and have the option to select your own instead of being stuck with the bank's choice.Title insurance covers you if the title company says "no problems with the title" and then it turns out something was missed down the line (e.g. an outstanding lien or something).

only allow to re-sign lease or move out?

If they can go to a car lot and walk in and sign their name and take that car over, it's going to move much quicker than it would selling your car in the front yard and them having to go find the money on their own.

Boarded up windows with the orange stickers are also a good sign.

My experience is they wont sign for certified mail.
