Can you have outdoor cameras to see who enters/exits the premises. 

I work for a LTR PM company and have been getting about a call a day since November of STR owners wanting to go LTR, but many of the homes are too big for LTR or they don't want to get rid of the furniture.

It has many tenants such as full size gym, yoga studio, NEW full outdoor area for pickleball, ju-jitsu, and other recreational programs that renting (16 total units - currently 9 are occupied).

You basically need to assign a value to all of the personal property (furniture, appliances, TVs, kitchen supplies, etc) inside the STR and they'll send you a tax bill based on the total. 

These would esquire you to spend 5-10x more time on the rentals,  and what if they produce the same or less income after you go out and buy all the furniture and start paying all the utilities.

Fast internet (there's a reason it's called Gig City), great population growth, industry (Amazon, Volkswagon, Unum, Erlanger, TVA, BlueCross, etc), outdoor living, etc.

I would say go the owner occupant loan route to get into something for 3.5-5% down instead of 20-25% that you'd need with an investor loan, but those require you to live in the property for a year before you could rent it out.Airbnb could be appealing also since you'd already be furnishing the place for yourself, could just leave the furniture there after you'd move out.

Just decks or even NO yard at all, I wouldn't recommend that kind of design for you with a 3/2 your likely going to have family with kids.. they need outdoor space.Also did you verify the area has good internet?

Cleaning, restocking, rebuying broken furniture, hanging up new art, meeting with a general contractor, etc. your kids will be expecting the beach, and yet you will be hanging up wall art.
