It may cost you more to dispute or sue the seller than to just take care of it on your own.  

The next letter I got was only from one neighbor (the leader of the pack...) and said I was in violation of deed restrictions since some guests appeared to be "unrelated individuals" and the deed restrictions demand single family use.

Hey everyone , real quick, i just came across a decent deal price wise (-175K from comp with garage) its a 3/2 duplex 1100 Sq Ft  but has no garage or car cover. thoughts on demand for something like that or challenges ill run into with that decision?

I don't know if that's because they were the buyer and I was the seller but hoping to provide an additional POV

Ask him to book directly through the booking website if they're interested in booking, or if you think there's a demand for this, you could post your listing on a medium term rental website like FurnishedFinder. 

. - there are QOZs and seller finance which can help as well. 

Hi Jessica, the best way I know to gauge demand is to use www.Furnished Finder.com/Stats.

I got over 100 responses in under 24hrs (see the screenshot) so the demand is real! 

I know it doesn't fully protect me for the lender calling the loan... but as far as recording goes, the seller would be the trustee so it would be his name recorded instead of mine.

Next do a search for Class A ($270,000 to $350,000+) and see how many fewer properties there are - those are in high demand or primary home owners don't want to sell since they probably have a below 4% interest rate.
