What options have people used if say the existing tenants aren't fully moved out, or left it in a condition that needs repairs that the new tenants couldn't move in yet?  

We liquidated two, got all our initial investment back, and have three reperforming notes left with a relatively high UPB, on which we plan to collect the entire amount.

Sure seems like a ton of work, risk and frustration only to have to give 40ish% of your profit to taxes and split what's left with a realtor.

We are going to rent our current home which has $90,000 left on the note at 3.25 percent and in ten years will be paid off.  

With regard to your case, don't even consider withdrawing the case from State court UNTIL they have actually moved out and left it in a somewhat decent condition (good luck with that one).

Sorry I know this is long and I may even left some things out.

That sounds like awesome goals and its great that it aligns with your passions. 

Whatever is left over after depreciation recapture is what you have to play with.With respect to C), You can still do a 1031 exchange; you just cannot accept the note.  

My friend was left some property in the Bahamas. 

So they left their keys on the desk of the local lender.
