The place must meet the 3 S's: Safe, Sanitary, Structurally sound.

Otherwise you might as well accept an iou written on a napkin. 

Can even use a napkin.

Don't forget about consumables like paper towels, napkins and TP.Some things like sheets and pots and pans have to be replaced at certain intervals or when damaged.I charge a little more for the cleaning fee to offset some of these items.

#2Back-of-the-napkin math is great for investors who already know what they’re doing, but newer investors really need to master the numbers behind real estate.

A 70 unit facility most likely won't be able to support a on-site manager.We run our facilities remotely and utilize a local caretaker for on the ground tasks.When it comes to running numbers, my back of the napkin math looks like this:Projected gross income (I'm usually looking at a $/SF number between the 10x10 and 10x15 sized units of nearby competition)x 90% occupancy- 35% expenses= stabilized NOIObviously, this is a gross simplification, but is typically where I start.If you do get into storage, you'll find that it is a great business to be in. 

You won't have to worry about leaks, repair costs, floor damage or sanitary concerns.

This is liquid from a clean and sanitary source, such as faucets, toilet tanks, drinking fountains, etc.

Neither of which could be done safely of course.So, the municipality has no way of knowing whether a unit was returned to the landlord in a safe and sanitary and habitable condition, short of performing inspections after any change in occupants.
