I plan on having my handy man build a closet in the larger of the 2 rooms to make my house a 4 bdr.I plan on acquiring 2-3 properties in the next year.

I offer portable ACs and do this regularly.

Will also take the air mattress off in the description and just leave it in the closet.

Are you talking soaking tub, dual vanity, separate water closet and walk in shower, and room for a bench to spare?  

The storage units in the basement will simply be small closets with locked doors for each unit.

Currently, the Half-bath has one sink and one toilet and is somewhat of a "closet" in size parameters.

My 2 cents...Up here any panel in a closet is a Code violation & must be moved.Our insurance carrier will cancel I we have fuses so we would need to update that sub-panel & the Al circuitry by default when its moved.

A huge master suite on the first floor with his & hers walk in closet a huge walk-in shower and garden tub.

Purchase price: $140,000 Cash invested: $60,000 Sale price: $365,000 Gutted center two bathrooms and closet areas, removed 12 feet of rock wall between kitchen and primary living room, and enclosed garage adding a laundry room, pantry, and HVAC duct.

FHA has a lot of safety requirements be met, for example, you can't have a closet pull chain light that doesn't have a globe cover and there must be no chipping paint inside or outside the home.
