I advised him not to be threatening or accusatory, just state the reasons they can’t stay there and ask for full refund.

Can you please advise me on what to do next or what constructive steps I can take to resolve this. 

There is SO MUCH advise that is thrown at us when we first get into real estate investing, it's hard to filter through it. 

I only advise people to get into short-term rentals IF you are going to make it your ONE THING and go all in on that...having to set up all the necessary systems is a HEAVY lift and not worth it without scale...I have done it and not at scale and it was not worth the hassle. 

Meaning, we can apply for relief and specifically monetary relief.By opening a claim using one of the links below you (and your tenants) can process a claim to get financial assistance.

You can see what the general advise is.

And if all checks out then it might be a viable deal from monetary stand point.

According to the data, Cape Coral is in for a wild ride and I advise bracing for impact.

The two most likely scenarios:1) They are driven by non-monetary factors (e.g., mission-driven: want to make the world a better place OR lifestyle: prefer the work of selling a program to the work of executing it) and they are willing to stomach any difference in income, OR 2) They are making more money selling the program to you than they are working it for themselves. 

You follow the sheepsass in front of you doing the exact same thing as they do, or you ask them for advise and willing to FRIGGIN BLINDLY accept said advise COMPLETELY ignoring logic.For Pete's sake people. seriously.What do you want your seller to think?
