How a self-storage lease-up is financed
A new facility produces almost no revenue for a year and full operating costs from month one. The interest reserve is the whole deal.

How is a self-storage facility financed during lease-up?
With a construction or bridge loan that includes a funded interest reserve sized to cover the gap between opening and stabilisation, then a refinance into permanent debt once occupancy and net operating income are proven. On a 5,200,000 loan at an illustrative 9 per cent interest only, a facility filling from 12 per cent to 88 per cent at 3.5 points a month runs a cumulative interest shortfall of about 542,000 over 24 months, which is the reserve you need. The two risks that break these deals are a slower lease-up than modelled and achieved rents below the assumption, and both compound because the reserve runs out while the gap is still open.
Self-storage has an unusual cost shape: nearly all the money is spent before anyone rents a unit, the operating cost is almost fixed regardless of occupancy, and revenue arrives one small monthly payment at a time over roughly two years. Lending against it means lending against a forecast of how fast strangers will fill a building.
Finance it with 5,200,000 at an illustrative 9 per cent, interest only: 468,000 a year, 39,000 a month. Stabilised coverage is 1.06 — thin, and a reason to question the loan size before anything else.
Now walk the lease-up, opening at 12 per cent occupancy and filling at 3.5 percentage points a month:
- Month 1: 12 per cent occupancy, revenue 9,384, net operating income negative 10,909, interest 39,000. Gap: 49,909.
- Month 6: 30 per cent, revenue 23,069, NOI 1,134. Gap: 37,866.
- Month 12: 51 per cent, revenue 39,491, NOI 15,585. Gap: 23,415.
- Month 18: 72 per cent, revenue 55,913, NOI 30,037. Gap: 8,963.
- Month 22: 86 per cent, revenue 66,861, NOI 39,671. The facility covers interest for the first time.
Cumulative shortfall across the period: about 542,286. That is the interest reserve, and a prudent sizing rounds it to 550,000 and adds a contingency.
What happens when the ramp is slower
Drop the fill rate from 3.5 points a month to 2.5. Stabilisation moves from 22 months to about 30, and the cumulative shortfall over 36 months rises to roughly 748,888. A reserve sized at 550,000 is exhausted somewhere around month 20, with the facility still 25 points short of stabilised and the sponsor writing cheques.
That single sensitivity is the deal. Everything else — the rate, the loan-to-cost, the exit — matters less than whether the ramp assumption holds.
Three things move it:
The structure, step by step
- Construction loan or bridge, typically interest-only, with a funded interest reserve and often a lease-up milestone schedule. Expect recourse, and expect a completion guarantee.
- Milestone tests. Many loans include occupancy or debt-yield tests at set dates. Missing one may trigger a cash sweep, a required paydown, or a springing guarantee rather than an outright default. Read what each test actually triggers.
- Stabilisation. Usually defined as a set occupancy held for a set number of consecutive months, or a debt yield threshold.
- Permanent refinance, sized on actual net operating income rather than projected, at whatever the market allows at that time. The refinance risk is the sponsor's, and a facility that stabilises into a higher rate environment may not support the take-out at the original loan amount.
- SBA-guaranteed options exist for owner-operated facilities and can suit smaller projects; eligibility, occupancy and use-of-proceeds rules are specific and worth confirming against current programme guidance at sba.gov.
The operating detail that affects the credit
What to present to a lender
- A unit mix schedule with square footage and street rate by unit type
- A month-by-month lease-up model showing occupancy, achieved rate and revenue separately
- A competitive survey: every facility within your trade area, their occupancy if obtainable, their street rates by unit type, and anything under construction or permitted
- A demographic and supply analysis — square feet per capita in the trade area is the standard measure and a lender will compute it whether or not you do
- Your interest reserve calculation, with a sensitivity at a slower fill rate
- Sponsor experience, which in this asset class carries real weight
What to ask for and what to refuse
Ask for the interest reserve to be sized on the slower ramp, not the base case, and ask what happens if it runs dry: does the sponsor fund, does the loan default, is there a springing recourse provision. Get that answer before closing.
Ask whether the milestone tests are measured on occupancy, on revenue, or on debt yield. Occupancy tests can be met with discounting that destroys the revenue the test was meant to protect.
Refuse a loan sized on stabilised value when the stabilised coverage is barely above 1.0, as in the example above. A facility that only just covers its interest at full occupancy has no room for the rate environment, the competitor or the wet year, and the equity behind it is the first thing to go.

Which funding products does this apply to?
Term Loan, Business Line of Credit, SBA Loan. Each has its own page listing the funders in this directory that offer it and what each one publishes about its terms.
Are the figures here quotes?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What a particular lender charges is on that lender's page, where it publishes it at all.
Who writes this?
The Find Me Funders research desk. Some drafting is AI-assisted, and every page that is says so at the top, including whether a person has checked its claims yet.
How do I know a figure here is right?
Where a page carries the green notice, its claims were checked against the sources listed at the end and a reviewer is named. Where it carries the amber one, nobody has verified it yet and you should confirm anything you plan to act on.
Are the examples real deals?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What any particular lender charges is on that lender's page, where it publishes it.
Why do you never say what a typical rate is?
Because we cannot source it. A market average assembled from lenders who do not publish prices is a guess with a decimal point on it. Where a lender publishes a figure, we show that figure and say where it came from.
Is this financial or legal advice?
No. It is general information about how these products work. Outcomes depend on your contract and your state, and a lawyer or accountant licensed where you are is the person to ask about your situation.
