I'm really interested in long term rentals along with Air B&B/VRBO. 

I’m active duty Air Force here in San Antonio.

Mainly you're responsible for the sewer bill and to provide heat and hot water, but not things like air conditioning.If this was winter, I'd be concerned about pipes freezing if the relationship isn't going well, but a 10 year tenant probably won't let that happen.I don't really know about the downsides of not having a lease. 

I'm not familiar with vrbo and other sites- but you could at least set up your own dot com booking funnel/site & (legal- per air bnb -personally don't know?)

Are these related to the air conditioners, or do they control the electricity for the entire house? 

Compete with new constructions with upgraded as granite or Quartz counter tops, central air and heat,and in unit laundry.

I look at a recession more like a thunderstom that clenses the air.

Here is a good overview of Sarasota & Manatee, keep in mind North Port has no rental restrictions at all and the city of Sarasota is 1-week minimum, if you are Zoned RMF on the barrier islands STR use is allowed, lastly I would check out GulfPort by St.

;) i’m thinking maybe something about an hour drive from one of the big airports. would make it easier for me flying in and renting a car.. 

They do not add more for garage, basement extra storage, central air conditioning etc, which are market rent additives.
