Why self-storage continues to be a growing real estate asset class
I have never rented a self-storage unit. I have stored things at my parents' places during certain periods of my life, such as when I moved to the US for grad school, but as a general rule, I never seem to conclude that I have too much stuff and that I should maybe rent some storage. However, I do on occasion fantasize about having a garage or large "man cave" where I could store an assortment of exotic snowboards, bicycles, and other life essentials. I mean, who doesn't, right?
In any event, I seem to be in the minority, because self-storage is a growing real estate asset class:
Investors have dramatically increased their allocation to self-storage over the last several years [in the US]. A rush into the asset class occurred from 2020 to 2022, when transaction volume hit $50 billion, far exceeding the $35 billion spent during the entire seven‑year period from 2013 to 2020, according to Cushman & Wakefield. Transaction volumes are now normalized but remain well above their pre‑pandemic baseline.
It proved to be the best-performing sector in the NCREIF Property Index from 2005 to 2022, with returns since 2010 nearly double that of the overall index.
So what's driving this? Some of the explanations include a frozen housing market, millennials who haven't yet bought a garage and are starved for room, and small-scale entrepreneurs who use it as cheap warehouse space. According to some reports, this latter use case accounts for nearly a third of total demand. And this makes sense to me. But generally, I have tended to apply an egocentric bias to this asset class. My mind discounts it because I don't personally use it.
