Does anyone has experience with purchasing self-storage facilities?

Easy access is key. If you're buying an existing storage facility, try to find one with room for further expansion.

I'm in the mobile storage business (i.e. pods). Never done a self storage deal but looked at a few. My biggest advice is look at it through a real estate investment lens as much as an operating co lens. Cap rates can be very low, especially for class A facilities, because there is institutional money going after these acquisitions. But if you can find a good deal or have a line on a good piece of property that can be developed, that can be a great way to make money. Whether you buy or build, my main advice is focus on maximizing the cash on cash returns while keeping the risk as low as possible. Feel free to DM if you want to talk more
