Three paths into this business: Start Independent vs. Buy Existing vs. Franchise for Self-Storage & Boat/RV Storage Facility
Path 1 · Build from Scratch
Start Independent
$460,000–$1,770,000
Ongoing royalties: 0% ongoing franchise royalty
Time to breakeven: 12–24 months
Tradeoffs: 100% control over pricing, vendor selection, and territory with 0% ongoing royalties—preserving the full 55%–70% SDE margin target owner cash flow once ramped. Capital is concentrated upfront in Prefabricated Steel Storage Buildings, Roll-Up Doors & Climate Dividers ($220,000–$950,000) and Land/Facility Acquisition Down Payment (SBA 7a / 504 10%–20% Equity) or Site Work ($180,000–$650,000); Required compliance includes Industrial / Commercial Self-Storage Zoning & Stormwater Permit (12–24 months typical breakeven).
Timeline: 45–90 days closing (immediate Day-1 cash flow)
Tradeoffs: Immediate Day 1 revenue (typically $280,000–$1,200,000 for established operators) with trained staff, permits, and vendor accounts in place. Priced at 6.5x–9.5x SDE (Valued on Net Operating Income (NOI) cap rates (6.5%–8.5% cap rate) with real estate included), typically financed via SBA 7(a) with 10%–20% down. Priority due diligence: Audit physical occupancy vs. economic occupancy (actual collected rent vs. street rates).
Disclosed FDD median brand revenue: $705,680 (across 2 catalog brands)
Tradeoffs: This specialty retail segment is overwhelmingly independent; operators retain 100% of equity and avoid 5%–8% gross-sales royalties by combining local storage, manufacturing & industrial relationships, trade association playbooks, and direct supplier terms.

SBA 7(a) underwriting & payback takeaway:
At $750,000 revenue and 63% SDE margin ($472,500/yr pre-debt cash flow), buying an existing self-storage & boat/RV storage facility at 8.0× SDE ($3,780,000) generates −$47,755/yr from Day 1 (0.91× DSCR), giving an immediate $106,395 Year-1 cash-flow advantage over building from scratch during a 18-month ramp-up. Once ramped in Year 2+, building from scratch ($1,120,000 CapEx) nets $318,350/yr (3.07× DSCR).
Estimated independent opening budget: $460,000–$1,770,000 (Down payment + expansion/automation CapEx on a 15,000–45,000 NRSF facility (or ground-up metal building build)).

Established self-storage & boat/RV storage facility operators generate $280,000–$1,200,000 in annual gross revenue (Monthly unit rent + tenant protection plans, late fees, and outdoor RV/boat parking) with an owner cash flow of 55%–70% SDE margin (Unmanned/remote management models keep operating expense ratios at 28%–38% of gross revenue).

Operating self-storage & boat/RV storage facility resales typically trade at 6.5x–9.5x SDE (Valued on Net Operating Income (NOI) cap rates (6.5%–8.5% cap rate) with real estate included), translating to typical acquisition prices of 6.5x–9.5x SDE ($1,001,000–$7,980,000). Key buyer due-diligence priorities: Audit physical occupancy vs. economic occupancy (actual collected rent vs. street rates).

Most self-storage & boat/RV storage facility operators launch independently or acquire an existing local resale rather than franchising. Independent ownership ($460,000–$1,770,000 startup budget) avoids ongoing gross-revenue royalties and territorial restrictions while allowing full customization of services and pricing.
