 A flood of new units in Sunbelt states means you might have the most bargaining power there. Also, you'll find cheaper spaces in the suburbs and beyond. And the climate-controlled properties have higher rents than the properties that are kind of your more traditional drive-up self-storage units. Also, if you're currently in a unit, you can always threaten to move out and try to ask for a price cut there. Of course, another way you might be able to save is to just hoard a little less.
