In Florida, there is no statutory provision governing non-renewal notice except for when the landlord requires the tenant to give notice of intent to vacate, in which case, the landlord has a reciprocal duty.

In Florida, I would be advising my client to deliver a notice to terminate the tenant with the biting dog based on a non-curable violation and to evict that tenant if they don't vacate in time.

My girlfriend and I are interested in buying into the upper Michigan STR markets (Traverse City, Charlevoix, Petoskey, Bay Harbor, etc), hoping we can take advantage of the hot vacation rental market up there in the summers and the popular ski slopes for the winters. 

AND try to find a market where you do not have to compete as much with 2nd home demand - a place where people go to vacation but is not top of mind for a rich guy's vacation home destination (ski town, lake house, etc.).If you are asking for the secret market that returns 20% cash on cash without any renovation or difficulty, that doesn't exist.

A totally managed vacation rental - think ski condo in a central managed destination. 

Typically, short term vacation rental management in our area of coastal Oregon can typically range from 20-35% of the gross revenue!?

The best find I ever had was a plastic kiddie pool with a built in slide in an old tool shed that was left behind so it definitely beats me.I know most people would advise reinvesting your findings or maybe splurging on something you've always wanted like a car, vacation, trip to space, or a pony.

We vacation there regularly:  Dauphin Island - 2017, Orange Beach - 2022, Gulf Shores - 2023, Fort Morgan - upcoming 2024.My guess is that Dauphin Island doesn't see the same appreciation as Gulf Shores, Orange Beach, and places eastward. 

Then purchase a vacation condo/cabin for trips and quality of life.

Vacations are to relax and de-stress.
