Faster than most people think. If you're paying $100 a month for a storage unit, that's $1,200 a year. A solid 10×12 shed purchased outright runs around $4,000 to $5,000. In three to four years, the shed has paid for itself, and from that point on, your storage is free for as long as the building stands.
Which, with Amish-built quality, is a very long time.
Even on rent-to-own, once you've finished your payments, you own it outright. Compare that to a storage unit where you could pay $100 a month for ten years and still own absolutely nothing.
