How lenders see storage
Canadian lenders have come a long way on self storage. Fifteen years ago many treated it as a specialty asset with no tenants and no leases, priced it accordingly, and required personal guarantees on everything. Today the major banks, most credit unions and a range of private and institutional lenders have storage programs, and a stabilized facility with a clean rent roll is one of the easier commercial properties to finance. Lenders like the diversified tenant base, the low capital expenditure and the sector’s record through the last two downturns.
They still underwrite it carefully, and the way they do it shapes what a buyer can pay. This article covers how a storage loan is sized, the terms to expect, how construction and lease-up financing differ, and how to choose between lender types.
The two ratios that size the loan
A lender sizes a storage mortgage on two constraints and lends the lesser of the two.
Loan-to-value (LTV) is the mortgage divided by the appraised value. Canadian lenders typically go to 60 to 75 per cent LTV on a stabilized facility, with the higher end reserved for strong markets, experienced borrowers and larger, newer buildings. The appraisal, not the purchase price, sets the value, which is why a buyer paying above appraised value funds the gap with equity.
Debt service coverage ratio (DSCR) is NOI divided by annual mortgage payments. Lenders generally require 1.25 to 1.40 times coverage on a stabilized facility, meaning the facility must earn 25 to 40 per cent more than the payments. The NOI they use is their own underwritten figure, with the same normalization described in the valuation article: a management fee whether or not the owner self-manages, a capital reserve, current property tax and insurance, and often a vacancy allowance above the facility’s actual number.
In a higher-rate environment DSCR is usually the binding constraint. A facility with $650,000 of underwritten NOI and a 1.30 coverage requirement can support $500,000 of annual payments. At a 5.5 per cent rate on a 25-year amortization, that supports a loan of roughly $6.8 million. If the facility appraised at $10.5 million, the 70 per cent LTV limit would be $7.35 million, so DSCR governs and the buyer needs about $3.7 million of equity on a $10.5 million purchase, or 35 per cent.
Terms to expect
Conventional term financing on a stabilized Canadian storage facility in 2026 commonly looks like this: 60 to 75 per cent LTV, 1.25 to 1.40 DSCR, 20 to 25 year amortization, a one to five year term, and a rate set as a spread over the lender’s cost of funds or Government of Canada bond yields. Personal guarantees are usual for private borrowers on smaller loans and negotiable on larger, lower-leverage deals. Lenders want a current appraisal, an environmental assessment, a building condition report, the trailing twelve months, the rent roll and the borrower’s financial statements.
Storage is not eligible for CMHC mortgage insurance, which is for residential rental housing. That matters because the CMHC-insured financing that lets apartment investors borrow at 80 per cent or more with long amortizations at low spreads does not exist here. Storage leverage is conventional commercial leverage.
Construction and lease-up financing
Financing a development or a conversion is a different product. The construction lender advances funds in draws against completed work, verified by a cost consultant, and charges a higher rate, commonly prime plus a margin or a floating rate plus a spread, along with fees. Equity requirements are higher, typically 35 to 45 per cent of total project cost, and the lender wants the equity in first. The loan includes an interest reserve to cover payments during construction and the early months of lease-up, sized as described in the lease-up article.
The construction loan is sized on projected stabilized NOI, discounted for risk, and it comes due on a fixed date, usually two to three years after closing with extension options. The developer’s plan is to reach stabilization before that date and refinance into a conventional term mortgage on actual NOI. If lease-up runs long, the extensions get expensive and the lender’s patience becomes a real constraint. Construction lenders underwrite the borrower’s experience and financial strength as heavily as the project, and a first-time developer without a storage-experienced partner will find the terms reflect that.
Bank, credit union or private
Chartered banks offer the lowest rates and the most conservative underwriting. They prefer stabilized facilities, experienced borrowers, larger loans and strong markets, and they take longer to close. For a well-run facility in a major or secondary market with a borrower who has a track record, a bank is usually the cheapest money.
Credit unions have been the most active storage lenders in much of Western Canada and in many secondary markets. They are often more flexible on facility size, location and borrower profile, will look at lease-up and value-add situations a bank passes on, and make decisions locally. Rates are competitive, sometimes slightly above bank pricing, and relationship matters. Credit unions are also constrained by provincial regulation and their own balance sheets, so a large loan may exceed a single credit union’s limit and require a syndicate.
Private and alternative lenders, including mortgage investment corporations and specialty commercial lenders, price higher, often several hundred basis points above bank rates, with fees on top, and lend on shorter terms. They exist for situations conventional lenders decline: a facility in lease-up with no operating history, a borrower with a complicated financial picture, a conversion with an unusual building, or a fast closing that a bank cannot meet. Used deliberately as bridge financing with a clear path to conventional refinancing, they are a legitimate tool. Used because no one else would lend, they are a warning sign about the deal.
The Business Development Bank of Canada also lends on commercial real estate including storage, often with longer amortizations and more flexible terms for smaller owner-operators, at rates above the banks.
Refinancing and the maturity wall
Storage loans are short-term instruments on long-term assets. A five-year term means the owner refinances every five years at whatever rates prevail, and the past three years have shown what that can mean. Facilities financed in 2020 and 2021 at rates near three per cent have been renewing at five and six, and where the NOI did not grow enough to cover the higher payment, owners have faced equity injections, forced sales or lender workouts. The Refinancing Wall covers who has been exposed.
The lesson for a first-time borrower is to stress test the loan at refinancing, not just at closing. If the facility cannot cover payments at a rate two percentage points higher than today’s with the same NOI, the leverage is too high.
What a first-time investor should take from this
Expect to put 30 to 40 per cent equity into a stabilized acquisition and more into a development. Understand that DSCR, not LTV, usually sets the loan in the current rate environment, and that the lender’s NOI will be lower than the seller’s. Start with a credit union or a bank that has a storage program, and use private money only as a bridge with a defined exit. And underwrite the refinancing at the same time as the purchase.
The final article in the series covers the province-by-province rules: zoning and land use, lien rights and the sale of delinquent tenants’ goods, tenant insurance, property tax treatment and the role of the Canadian Self Storage Association.
