Rate of default

What percentage of storage tenants would you estimate go into default? 

i think thats way too broad a question depending on where the unit is located and the local demographic. overall? i'd say 10-20% but im just throwing a guess

Less than 1%.

"According to the Washington-based Self Storage Association, business is booming. There are about 48,500 primary self-storage businesses nationwide and 1,435 in Ohio, the industry’s fourth-largest state. About 9 percent of Americans rent the units to park excess belongings or to hold items when they move, travel or downsize.

Tim Dietz of the storage association said less than 1 percent of units nationwide wind up at auction."

Yeah, that would have been my guess as well. The average storage facility has 300-400 units and on average, 3 units go to sale each auction.
