We need an additional $60k to bring the home up to "Vacation Rental level", i.e. swimming pool, furnishing, landscaping, decorating.

The entire downtown is full of artists, galleries, and pleasing-to-the-eye decorations everywhere.

Maybe enclose it and decorate around it.  

I enjoy decorating and fixing things. 

I install decorative concrete flooring for investors in the Phoenix area.

l do have a clause:  PREMISES MODIFICATION:There is to be no painting, decorating, gluing, wall papering, placing of hoods in the ceiling, carpeting, outside additions, buildings or modifications, or any other material changes made to the leased Premises without the permission of the LESSOR.

For a multi ductless system, you will most likely pay twice as much as a traditional central HVAC system.Have you considered adding decorative soffits to your ceilings that the ductwork could run through?

I usually get my floors from floor and decor.

Floor & Decor has a good selection of cheap tile and my handyman does a great installation.
