I am a real estate agent in South Florida that specializes in short term rentals 😊 would be happy to set up a call with you and chat! 

While they are legal from a building department view point, if there are complaints from neighbors about you renting it long term, it could create issues with zoning.  

A year of rent sounds great on the surface but I'm wondering why they wouldn't just pursue a normal year long (long term) rental...maybe they've been bad renters or have bad credit or low income.

In addition if you can creatively solve some of the 3d printing short-comings (OP is creative director) you could be market leader.

I don't remember the exact term, but there is a category of insurance providers...

One I know is days on the market but I would like to know a strategy more in terms of the work needing to be done on the property.What is the typical rehab budget for a full gut versus a fixer-upper that needs some updating such as for the kitchen, bathroom, new carpet, roof, and/or driveway for example?

We have great long term residents in our POH rentals and do very well financially with them. 

They already agreed to the sale price and payment terms.

Efficient negotiations secured the property for $200,000 on favorable terms.
