Most operators treat the first rate increase like a move-out trigger. So they delay it, shrink it, or skip it.
We pulled 74,000 leases across 68 operators on Cubby and followed every tenant from move-in through their first year. Being in the window after a first ECRI moved the monthly move-out rate by 0.18 points, against a baseline of 9.2%. Statistically, that's nothing.
The curve only bends when the increase gets big. Up to about 30%, retention looks like no increase at all. Past 50% it starts to erode. Past 100%, those tenants retain about 16 points worse than everyone else.
So the routine increase, with 30 days' notice, costs you essentially no extra move-outs. The aggressive one does.

We analyzed 74,000 leases across 68 self-storage operators. A first-year ECRI with proper notice barely dents retention — until the increase tops 50%.
