Other than for short term..... storage facilities are a joke! Too many people get one, fill it, then never ever use what's in it! They pay every month and by the time they wake up and realize they have wasted their money, they also realize the money they spent on useless rent could have replaced what's in the unit quite a few times over! When they pass away, the kids either throw everything in a dumpster or just let the storage facility break the lock and auction it off for lack of rent money.
I have known so many that have fallen into this trap! I have also given this speech to many - some listen, most don't!
What ever you don't use within a 6 month time frame - sell, give away or throw out! Save the senseless storage money and buy a few of the items you got rid of, if and when you ever need them. You more than likely won't if its in a storage facility!
AGAIN, short term is a different situation.
