How Much Do You Need to Borrow to Open a Self Storage Facility?
A self-storage business loan typically runs $675,000 to $1,310,000, covering about 75% of the build-out cost. Revenue Map's self-storage presets model a default $1,050,000 loan at 7.5% over twenty years against a $1,400,000 build-out for a 300-unit drive-up facility, with monthly debt service near $8,460.
Self-storage lending is real-estate lending: the collateral is the land and the building, which is why loan-to-cost ratios of 75% are standard and terms stretch to twenty years. Revenue Map's presets model a $1,400,000 build-out for a standard 300-unit, 30,000-square-foot drive-up facility, financed with a $1,050,000 loan at 7.5% over 240 months. The owner contributes roughly $350,000 of equity on top, plus $500,000 of phase-one working capital to absorb the eighteen-month lease-up.
What makes storage lending different from other commercial loans is the lease-up curve. A new facility starts at 45% occupancy in Revenue Map's presets and takes eighteen months to approach stabilized occupancy near 88%. During that ramp the facility loses money by design, and the working capital exists to cover eighteen months of debt service, staff, utilities, insurance and marketing while the units fill.
Cost Breakdown
Self-storage loan sizing by facility format
| Item | Typical range | Notes | Source |
|---|---|---|---|
| Default loan (300-unit drive-up) | $1,050,000 at 7.5% over 20 years | Covers 75% of a $1,400,000 build-out for a 30,000 sq ft facility | Revenue Map model presets |
| Loan by format | $500,000 to $1,310,000 | Portable containers at $500,000 on $700,000 capex, climate-controlled at $1,310,000 on $1,750,000 capex | Revenue Map industry presets |
| Monthly debt service (default) | About $8,460 | Principal and interest on $1,050,000 at 7.5% over 240 months | Revenue Map model presets |
| Owner equity required | $175,000 to $440,000 | Covers the 25% equity gap between the loan and the build-out across formats | Revenue Map model presets |
| Build-out cost range | $700,000 to $1,750,000 | Portable container yard at the low end, climate-controlled facility at the top | Revenue Map industry presets |
| DSCR floor for lender approval | 1.25 or better | Real-estate-backed collateral, but the occupancy forecast during lease-up must hold | Revenue Map model templates |

What Moves the Number
Format sets both the loan and the lease-up profile
Revenue Map's industry presets show a portable container yard at $700,000 capex with a $500,000 loan and 220 units at $135 per month, versus a climate-controlled facility at $1,750,000 with a $1,310,000 loan and 260 units at $145 per month. A conversion facility, repurposing an existing building, sits at $1,100,000 capex with 400 units at $98 per month. Each format produces a different revenue shape against a different debt load.
The eighteen-month lease-up is what the equity absorbs
Revenue Map's presets model an eighteen-month ramp starting at 25% of phase-one demand. At 45% occupancy and $105 per unit per month, the facility generates roughly $14,200 of gross revenue against monthly obligations near $17,300 including the loan. The $500,000 phase-one investment exists to carry the business through those underwater months while units fill.
Occupancy drives everything after the build
At the default $105 monthly rate with 3% cost of goods, each occupied unit contributes roughly $102 per month of gross profit. Monthly fixed costs plus debt service total about $17,300, so break-even sits near 170 occupied units, which is 57% occupancy on a 300-unit facility. Getting from 45% to 88% is the entire financial story of the first three years.
Twenty-year amortization matches the asset life
The default $1,050,000 loan at 7.5% over twenty years carries about $8,460 per month. The same loan over ten years would be roughly $12,450, which would push break-even occupancy well above 70% and require far more working capital during the lease-up. Twenty years is standard for commercial real estate because the asset life exceeds the term.
