If the wiring is nonmetallic cable (romex - plastic looking outside layer of insulation) and has a ground wire (3rd wire, bare copper) it might be fine to keep.

you don't need off market land. most land is listed is fine. it's a buyer's market for land in most markets which means more than a 6 month supply. practice underwriting the deals and making offers, find deals they may do owner financing, etc on. 

Violators may be fined and also be required to repay all overpaid rental assistance.2. 

My seller would be fine just releasing the earnest money but without any consent to cancel the contract from buyer I’m not even sure where to go from here.

In majority of instances seller financing for the seller is a horrible idea and should only be an option when the home doesn’t get conventional financingMany will disagree with above which is fine - it’s similar to winning lottery and taking lump sum over payments.

If you learned from it, including learning that index funds are a better fit for you, then it was a fine purchase (and how I chose to look at my 2 poor RE investment purchases, I learned from them and they were part of the path to where I am today).  

You’re breaking even, which is fine if you’re playing the long game.

Set up a manager-managed LLC with you being the member, you should be fine with lots of wholesaling & flips.

Every year I sell properties for investors after they've been fined tens of thousands of dollars by their HOA for using the property as a STR against association rules.

Regardless, you should be fine with taking back possession.
