Including a portable crib and games goes a long way. 

And you need them to STAY, because turnover will kill you with no apologies here.My situation is entirely different from a tech guy living in a walk-in closet in Palo Alto, some dude who wants to hedge his tech stock picks with a turnkey property or two in Indianapolis. 

Looking for info on getting started in portable storage.

Purchase price: $729,000 Cash invested: $250,000 Sale price: $1,550,000 We performed the following renovations prior to selling the house:-Converted an open dining room into a 4th bedroom creating 2 closets and french doors-Renovated the kitchen and master bathroom including moving water lines and venting-Installed a beam creating an open archway-Covered the fireplace and installed custom cabinets in the living room-Built a patio with pavers and a pergola-Removed concrete patio and installed sod-Installed can lighting -Carpentry -Paint

I don’t know if the area is right or not, but I have heard of some investors doing glamping, portable tiny house, or renovated airstream for rental.

It wasn't a ton and then there was another corner of the wall in the closet that the mold started from the floor up the wall about 12 inches but only in the corner about two inches in width.

The first floor did not have a bathroom so we replaced an under the stairs closet as a powder room.

This is how we get units in NY/Chicago that resemble a broom closet.  

Added laundry closet in large dining area.

Cat urine smells can be a mold problem as well... so check closets, cabinets, etc.
