No, to many issues and it only fits one guy.If I did STR's and wanted a hot tub (they are technical called a spa ), I'd pop about 5 grand (or so) for one (maybe on payments) that seats vs lays down about 7 seated guys.With a cover for it, and run the (probably 50 amp GFCI breaker, wiring and cutoff to it) (probably $1,500 or so electrician rates).It also needs a concrete slab under it of X inches thickness to hold the weight.Then build a small deck around half of it at rim height.The proper hot tubs hold about 400 to 500 gallons (or more) of water and that needs to be dumped about 4 times a year, with chemicals added to the existing water on a regular basis (pool service or self labor (not renters doing it).Typical they heat 24/7/365 and might cost $3 or $4 a day to keep hot (depends on your electric rates and the amount of insulation the unit has, as well as your outdoor temps..Austin will cost less then Alaska).

So technically, am I the general contractor?

Also, technically it is a 10% rule--you have to stay there a minimum of 14 days a year OR 10% of the total number of days rented.

The problem is this technically activates the 'due on sale' clause.

It is not easy to get it done so you would need to find a lender who will dig in, but it is technically possible from the FHA perspective.FHA handbook on commission income

Over the last year, I've had the privilege of working for dozens of property management companies and spoken with hundreds along the way about what's working at what isn't.While I know that some teams are short staffed and can't keep up with such a hot market, others are saying they can't seem to price their units effectively or need help with maintenance automation.

Technically my job isn't requiring me to move (I can be based out of anywhere), but moving to another city with better transportation would improve work efficiency. 

It is technically a pile of assembled building materials.

Technically, it wasn't on record as a 3 bedroom, but it had all the features of it.
