I am not a junk collector and I am not a storage facility.

Maybe tenants in larger buildings expect more noise or the necessity to share parking and facilities, etc.  

I've been a facilities Technician for 20 years and people throw full plates of food and coffee grounds, rice spaghetti and everything else down those things.

Yes, they are "rougher" on the facilities, but I'll take that over difficult to evict tenants. 

However, we were in the facility (dealing with a so called mice problem by them) a couple days prior and noticed that they had cigarette butts in their rooms in huge ash trays and all smoke detectors had been removed and obviously it smelled like smoke.  

Depending on demand I would look into a daycare facility with an educational twist.

You can but it take's WORK.I was a Regional Facilities Manager for years.

MAINTENANCE OF PREMISES.Landlord will maintain all electrical, plumbing, heating, and other facilities and appliances supplied by Landlord in reasonably good working order.Landlord will perform periodic inspections of the premises, no less than once a year, for the purpose of property maintenance and repair.Landlord will notify Tenant in advance of the inspection.

The growth rate for this real estate niche ( senior assisted living facilities) is double digits annually into 2030 by all accounts.

I spent $100,000 to buy a storage facility that grosses almost $10,000 a month.You're essentially betting on appreciation when the market is likely at or near it's peak, in a state that is losing businesses and a large number of upper-middle-class and wealthy people.
