See If Your Self Storage Site Is Worth the Investment.

A lot of documents are called feasibility studies. Some of them are twelve pages of census data with a pro forma template stapled to the back, and they will not hold up to a lender’s questions or yours. Here’s what actually should be included so you can make informed, confident decisions.

Demand should be measured locally.

National statistics about square feet per capita make for good conference slides and bad investment decisions. What matters is the trade area immediately around your site, which is a three- to five-mile ring in suburban markets, tighter in dense urban areas and considerably wider in rural ones. Within that ring, population, household income, renter percentage, household size and the age of the housing stock all shape how much storage the area will absorb, and household turnover matters most of all because storage demand is driven by people in motion. A useful study calculates demand for your specific ring and then compares it to the supply already inside it.

Competitors have to be measured, not assumed.

Occupancy and street rate tell you whether a market is tight or soft. Neither number is reliably available online. Facilities publish web rates that may not match what they quote at the counter, and nobody publishes occupancy at all, so getting a usable picture means calling, shopping and in some cases standing in the parking lot counting doors. The harder part is finding the supply that has not opened yet.

The unit mix has to match the renter.

Unit mix is where projects quietly lose money for years. The mix should come from what the local competition is actually renting and what they are struggling to fill, rather than from whatever the builder put up on the last job.

The financials have to survive underwriting.

A lender is not reading your self storage market study to be inspired by it. They are reading it to find the assumption that makes or breaks a deal, and they have seen enough storage deals to know where to look.

That means your rate growth has to be conservative enough that nobody has to argue about it, your expense ratio has to reflect what facilities in that market really spend and your development costs need to come from your builder rather than from a rule of thumb someone repeated at a conference.

The recommendation has to be an actual recommendation.

The most useful page in any study is the one where somebody who has done this before tells you what they think. Data that stops short of a conclusion just hands the hardest part of the job back to you.

What a study cannot do.

A study can’t promise you a return or predict a recession. Nor can a study rescue a site with no visibility, though it can tell you that’s a potential problem before you spend anything else to find out. A feasibility study replaces guessing with evidence, surfaces the risks early enough that you can still act on them and gives you something credible to put in front of a lender or a partner who is going to ask hard questions.
