The part of the pro forma that goes wrong
When a new self storage facility underperforms, the problem is rarely the building and rarely the market. It is almost always the lease-up assumption. The pro forma said 36 months to stabilization; the facility took 54. The pro forma said no concessions; the facility gave away a free month for two years. The pro forma assumed a street rate that the market never paid. Each of those misses is survivable on its own. Together, they turn a good project into one that runs out of cash before it reaches break-even.
This article covers how lease-up actually works, what drives its pace, what it costs to carry, and how to set targets that a lender and a partner can hold you to.
What lease-up is
Lease-up is the period from opening day to stabilization, when the facility is filling for the first time. Absorption is the pace of that filling, measured in units or rentable square feet per month, net of move-outs. Stabilization is the point at which occupancy reaches a steady state, typically in the high 80s to low 90s per cent physical, with rents at market and turnover at a normal level.
A new facility opens at zero occupancy with a full expense load: property tax, insurance, utilities, staffing or remote management, marketing and, above all, interest on the construction or acquisition debt. Every month until revenue covers those costs, the owner funds the difference from equity or an interest reserve. Lease-up is the period in which the facility consumes capital rather than producing it.
How long it takes
Across Canadian markets, a well-located facility of 40,000 to 80,000 rentable square feet typically absorbs 1,500 to 3,000 square feet per month net in a healthy under-supplied market, which puts stabilization 24 to 36 months from opening. Facilities in dense urban markets with strong visibility can fill faster. Facilities in markets that were already adequately supplied, or that opened in the same year as a competitor, commonly take 40 to 60 months.
Three things set the pace. The first is trade-area supply and demand, which is fixed by the time the facility opens and which the market article covers. If the three-kilometre radius already had four square feet of storage per person, no marketing budget changes the outcome. The second is the seasonality of demand: Canadian storage rents fastest from April through September and slowest from November through February, so a facility that opens in October spends its first winter absorbing almost nothing. The third is the operator’s execution: online rentals, an effective website, paid search, road signage, a phone that gets answered, and a rate strategy that fills the facility without giving it away.
What it costs
The cash required during lease-up has four parts.
Operating shortfall. Fixed costs run from day one. A 60,000 square foot facility in a secondary Canadian market carries $250,000 to $400,000 a year of operating expenses before debt service, and revenue in the first year covers a fraction of that.
Debt service. Construction and lease-up loans accrue interest on the drawn balance, and once the facility opens, the lender expects payments. An interest reserve, sized in the loan at closing, covers this for a set period, typically 12 to 24 months. If lease-up runs past the reserve, the owner funds the gap.
Marketing. A facility in lease-up spends three to five times as much per month on marketing as a stabilized one, most of it on paid search, aggregator listings and signage. Budget two to four per cent of stabilized revenue per year during lease-up, front-loaded.
Concessions. Move-in incentives reduce first-year revenue below what the rent roll suggests. A first-month-free promotion on a $180 unit that stays 14 months is an eight per cent discount on that tenant’s first year.
Add those up and a facility that cost $10 million to build can require $1 million to $1.5 million of additional capital to reach stabilization, or 10 to 15 per cent of the project cost. Lenders know this, which is why construction loans require an interest reserve and higher equity. Developers who forget it are the ones who end up selling a half-full facility to a buyer who understands lease-up better than they did.
Break-even occupancy
Break-even occupancy is the level at which revenue covers operating expenses and debt service. It is the single most useful number in a lease-up plan because it defines the finish line for the cash burn.
The arithmetic: a facility with $350,000 of annual operating expenses and $550,000 of annual debt service needs $900,000 of revenue to break even. If stabilized revenue at full market rents and 92 per cent occupancy is $1,200,000, the potential gross revenue at 100 per cent occupancy is about $1,300,000, and break-even is roughly 69 per cent occupancy. A facility absorbing 2,000 square feet a month on 60,000 rentable square feet reaches 69 per cent in about 21 months, which tells the owner how much cash to raise and when to expect it to stop.
Conservative lease-up plans set break-even below 70 per cent. Plans that require 80 per cent or more to break even have no margin for a slow winter, a competitor opening across the street or a rate environment that moves against the refinancing.
The rate question during lease-up
The instinct in lease-up is to fill the building as fast as possible with low rates. The problem is that every tenant who moves in at a discounted rate stays at that rate until the operator raises it, and raising rates on a large cohort of early tenants at once produces move-outs just as the facility is approaching stabilization.
The better practice, and the one professional operators use, is to open at or near market street rates, use short-term move-in incentives rather than permanently reduced rates, and start the annual rate increase program on early tenants at their first anniversary. Occupancy fills slightly slower, but the facility stabilizes with in-place rents near market, which is what the refinancing lender and any future buyer will value it on. Filling fast at low rates produces a full building that is worth less.
Lease-up and the lender
The construction lender sizes the loan on the projected stabilized NOI, discounts it for lease-up risk, and requires the interest reserve and equity described above. At stabilization, the owner refinances into a conventional term mortgage sized on actual NOI, which is the moment the development return is realized. If the facility stabilizes with in-place rents below market, that refinancing is smaller than planned and the developer’s equity stays trapped longer. Lease-up execution and the refinancing outcome are the same problem viewed from two ends.
What a first-time investor should take from this
Lease-up is the risk that development and conversion carry and acquisition does not. Plan for 30 to 36 months to stabilization in a good market and 48 or more in a competitive one. Budget 10 to 15 per cent of project cost as lease-up capital, separate from the construction budget. Know the break-even occupancy before breaking ground. And open at market rates with move-in incentives rather than filling the building with permanent discounts.
