I believe though I can't find a link that you basically need:  egress window, heat, electric, closet, ceiling height minimum 7 feet but there can be places where beams take it down to 6'4". 

Short term is under a lot of heat with tons of taxes like mentioned earlier.

That includes water, sewer and in one case heat. 

The roof and A/C are covered also especially in the 100+ degree heat only a matter of time before they need replacing also. 

It keeps you cool in the heat, or warm when it's cold, it's very durable, it'll even out the tire pressures in your car and get you 15% more back on your taxes.

Im looking for a duplex for rental income here in miami fl.

Miami-based Brightline Trains is gambling $200 million it received in bonds from the Nevada State Board of Finance to help fund its planned 170-mile high-speed rail line between downtown Las Vegas and Victorville, which has a target completion date of 2023.

The rehab included all the HVAC systems (going from a leaky oil furnace to a heat pump and new ducts), insulation, LVP in most of the house, and fairly extensive work in one bathroom.

Keeping the roof patched, heat on, yard watered and mowed, etc. 

I can say with certainty that the market is over heated and as soon as the fed stops printing money, it will deflate like a balloon.
