Risks of self storage investing
The risks of self storage investing: local oversupply, slow lease-up, rate sensitivity, execution risk, and illiquidity — and how each is underwritten.
No investment is risk-free. The mitigations below are what we actually do — none of them eliminates the underlying risk, and every offering document sets out its own risk factors, which you should read in full before subscribing. For how these risks weigh against the return potential, see the complete guide to self storage investing.
Local oversupply
Storage demand is local. A facility two miles away that opens six months before yours can reset the rate environment for an entire submarket regardless of what national occupancy statistics say. Oversupply is the risk that most often turns a good pro forma into a mediocre outcome.
How we underwrite it: submarket-level supply analysis including permitted and announced projects, not just what is built today; a preference for infill locations where land cost and entitlement timelines constrain new competition; and walking away from markets where the pipeline exceeds our read of absorption.
Slower-than-projected lease-up
A development or conversion produces no income until it opens, then climbs to stabilised occupancy over one to two years. Every month that curve runs behind plan costs carry on the debt and pushes distributions out.
How we underwrite it: lease-up assumptions benchmarked against our own completed facilities rather than broker projections, an interest reserve sized for a slower curve than we expect, and staged capital deployment so a delay does not force a financing decision at the worst moment.
Interest-rate and financing risk
Rates affect a deal twice: the cost of debt during the hold, and the capitalisation rate a buyer applies at exit. A structure that only works at yesterday's rate is a bet, not an investment.
How we underwrite it: exit assumptions held at or above today's entry cap rather than betting on compression, debt terms that avoid a forced refinance inside the hold period where possible, and stress-testing distributions at higher rates before we commit.
Execution and sponsor risk
Storage returns come from operating a business, not holding a bond. Rate management, expense control, construction oversight, and lease-up marketing all have to be done well. This risk sits with the sponsor, which makes sponsor selection the diligence that most affects your outcome.
What to ask for: completed facilities you can visit, actual results against original underwriting, a candid account of a deal that underperformed and why, and confirmation that the sponsor's own capital is invested alongside yours.
Illiquidity and concentration
A direct or syndicated position cannot be sold when you want it to be. There is no secondary market, and your capital is committed for the full three-to-five-year term. A single facility also means single-asset concentration.
How to manage it: size any one position to capital you will not need, and diversify across projects and strategies over time rather than in one commitment. If you need liquidity, a public storage REIT is the appropriate instrument.
Regulatory, insurance, and physical risk
Zoning and entitlement decisions can delay or block a project. Insurance cost has risen materially in some markets. Fire, flood, and storm damage are real, as is the occasional legal cost of tenant lien and auction processes.
How we underwrite it: entitlement contingencies in purchase agreements, current insurance quotes rather than historical figures in the pro forma, and property-level reserves.
Read these alongside the benefits and the target returns — the returns exist because the risks do.
Frequently asked questions
What is the single biggest risk in a self-storage deal?
Local oversupply, and the slow lease-up it causes. Storage demand is intensely local — a competing facility within a few miles can change a submarket's rate environment while national statistics look fine. That is why submarket supply analysis matters more than any asset-class-level statistic.
How do rising interest rates affect a self-storage investment?
In two places. Financing cost rises, which reduces cash available for distributions on a levered deal, and exit capitalisation rates tend to widen, which reduces the sale price for a given NOI. We underwrite an exit cap at or above the entry cap rather than assuming compression, and prefer debt structures that do not force a refinance at an unknown rate.
What happens if the sponsor fails to execute?
It is the risk least visible in a pro forma and the hardest to recover from. Mitigation is diligence: a track record of completed facilities, references, real disclosure of a deal that went badly, and an operating agreement with meaningful sponsor capital alongside yours.
