Furnished it as my family were staying there.

This is my main question:The house needs 50-80K rehab and will need about 10K for furnishings thereafter— I need to get financing for this.

Beyond that you can also search google "Monthly Furnished Housing for Travel Nurses" which will give you valuable information.

Moab could also be a great place for a short term rental and you can use your savings to furnish one of the units.

I need to put two superintendents up in 2 furnished rentals. 

I found this tenant on furnish finder and reached out and responded to their housing request. 

If it is a smaller house they do a lighter stage rather than a full furnishing.

Have you looked into doing the furnished monthly rental thing? 

If you provide any furnishings or removable appliances you would insure those as Contents.  

However, like I mentioned above STR's can me much more work so, while it is nice to have that option to continue renting out bnb as STR, I typically turn that furnished BNB into a MTR (1-6 months) for traveling nurses and young professionals.
