It is starting to see some increased activity with a couple of larger companies building facilities in the area, and buyers priced out of Raleigh can still find a nice home at a reasonable price. 

The listing agent tells me that the price is non-negotiable due to it having been set by Medicaid (the owner is in an assisted living facility). 

I own one storage facility that is a dump (but it makes really good money) and I want to completely overhaul and modernize it but the prices don't make sense right now.

Quote from @Emma Hustis: I am talking to an off market seller of a 120(ish) storage unit facility in Bonner's Ferry, Idaho (near where I live). 

Mark,We have purchased MANY Self Storage Facilities with little to $0 Money down, with the seller Carrying back a mortgage (VTB).  

Self storage on the other hand has the supply risk where a new facility can go in down the street and pull your occupancy down while they lease up for the next year or two.

Easy Storage Solutions is built for smaller facilities, and I've heard of people hacking it to use for SFRs by making a unit to represent an SFR rental.

The key things to remember are these:  Self Storage is very local and the profit of an individual facility is, in my experience, almost always driven by the individual operator(s). 

You'd likely want to time this new payment structure with fair warning - say, January 1st, but since many facilities are month-to-month, I would roll this out in conjunction with any other improvements you might be making - Kiosks or apps for payment or the management software you'll be using to run the facility.
