I would start with something either turnkey or light value-add, so you can start forming your boots on the ground team with less pressure and risk.

My husband was just looking at his roast (light was on, didn’t touch the oven) and it shattered right in front of him, with me in the kitchen behind him.

For another vacant unit, we did some light renovation with new paint and new carpet.

It was 90k which included new sewer line, AC unit, flooring, paint, lights, kitchen sink and counters, bathroom.

You can use this to help offset expenses if something bad happens while you begin the process of taking back your house.There are certainly risks involved, but you seem to imply that this is likely the best deal that you will get so you need to weight the pros/cons and see if it is a good fit for you.The alternative is to ask if instead of doing the deal sub2, if the buyer is willing to buy the home on a wrap. 

Same for emails, voicemails and texts.It doesn't sound like you were represented by a buyer's agent and this is a perfect example of why a good Realtor is worth his weight in gold.
