Industry Terminology & Glossary
Master 100+ self storage terms across 7 modules. Complete all quizzes and the Final Exam to earn your Course 2 completion certificate.
Property & Facility Terms
Physical features, facility classes, unit types and the vocabulary of the building itself
Climate-Controlled
Indoor units kept at 55โ85ยฐF with humidity control. Commands a 20โ40% rent premium over standard drive-up units. Key differentiator for Class A facilities.
Net Rentable Area (NRA)
The total LEASABLE square footage of a facility. Does NOT include hallways, offices, or common areas. The key metric for valuation and benchmarking.
Unit Mix
The distribution of unit sizes (e.g., 20% 5ร5s, 35% 10ร10s, 25% 10ร20s). A well-balanced mix is critical for maximizing revenue across different customer needs.
Deferred Maintenance
Repairs or upkeep that have been postponed. A major red flag in due diligence. Often used to justify a price reduction in acquisition negotiations.
Financial & Investment Terms
NOI, cap rates, IRR, cash-on-cash, proformas and every deal metric you need to master
NOI โ Net Operating Income
Gross Revenue โ Operating Expenses. Does NOT include mortgage payments. The single most important metric in commercial real estate and the foundation of all valuation.
Cap Rate โ Capitalization Rate
NOI รท Purchase Price. Represents the yield if you paid 100% cash. A 6.67% cap rate = $120K NOI รท $1.8M price. Higher cap = more yield or more risk.
IRR โ Internal Rate of Return
The average annual return over the entire hold period, accounting for all cash flows and the final sale price. The gold standard for comparing investment opportunities.
T-12 (Trailing 12 Months)
Actual financial performance over the past 12 months. The most reliable baseline for underwriting. Always request the T-12 operating statement before making any offer.

Formula: Cap Rate = NOI รท Purchase Price
$120,000 รท $1,800,000 = ?
Operational Terms
Occupancy metrics, revenue management, KPIs and the vocabulary of running a storage facility
Physical vs. Economic Occupancy
Physical = units rented รท total units. Economic = dollars collected รท potential revenue. A large gap between the two signals high delinquency โ the real performance problem.
Street Rate vs. Contract Rate
Street Rate = current advertised asking price. Contract Rate = what existing tenants pay. A large gap means in-place rents are below market โ a major value-add opportunity.
ECRI โ Existing Customer Rate Increase
The scheduled periodic rent increase sent to current tenants โ typically 3โ10% annually. The most reliable driver of NOI growth without adding a single new unit.
Ancillary Revenue
Income beyond rent โ tenant insurance commissions, locks, boxes, truck rentals, packing supplies. High-margin add-ons that improve NOI without needing additional rentable space.
Financing & Lending Terms
LTV, DSCR, debt service, capital stack structures and everything your lender expects you to know
LTV โ Loan-to-Value Ratio
Loan Amount รท Property Value. Lenders cap self storage LTV at 65โ75%. On a $1M property, max loan = $650Kโ$750K. The remaining 25โ35% is your equity injection.
DSCR โ Debt Service Coverage Ratio
NOI รท Annual Debt Payments. Must be 1.25+ for most lenders. A 1.0 DSCR = NOI barely covers the mortgage. Any revenue dip and you can't make payments.
Bridge Loan
Short-term (1โ3 year) financing for value-add or lease-up acquisitions. Higher interest rate, interest-only payments. Plan: improve NOI, then refinance to permanent financing once stabilized.
SBA 7(a) Loan
Government-backed with only 10โ15% down. Best option for first-time buyers acquiring facilities under $5M. Requires owner-operation of the business. Up to 25-year term.

Legal & Tenant Terms
Lien laws, rental agreements, default, delinquency, auctions, and protecting yourself as an operator
Self-Help Remedy
The legal right UNIQUE to self storage allowing operators to foreclose on and sell a tenant's stored property for non-payment โ without going to court. No other property type has this right.
Overlocking
Placing an additional operator lock on a delinquent tenant's unit to prevent access until the debt is paid. A key step in the lien process after the late notice is sent.
Cure Period
The window of time granted to a delinquent tenant to pay all outstanding rent and fees before the lien sale proceeds. Duration is set by state law โ typically 30โ60 days.
Surplus Proceeds
If a lien auction generates MORE money than the total unpaid rent and fees, the excess must be returned to the tenant or remitted to the state. Operators cannot keep the surplus.
Market & Acquisition Terms
Trade area, saturation, absorption, off-market, due diligence and deal sourcing vocabulary
Sq Ft Per Capita
Total rentable storage in a market รท population. National average: 6โ7 sq ft. Under 7โ8 = undersupplied opportunity. Over 10 = potentially oversaturated โ proceed with caution.
Off-Market Deal
A property for sale NOT listed on public platforms like LoopNet or Crexi. Found through direct mail, cold calls, broker relationships, and networks like NSSIC. Where the best deals happen.
LOI โ Letter of Intent
A non-binding document outlining the key terms of a proposed acquisition โ price, contingencies, due diligence period, and closing timeline. The starting point of every negotiated transaction.
Due Diligence Period
The investigation window after an LOI or purchase contract is signed. The buyer reviews financials, leases, physical condition, environmental reports, and legal history before committing.

Syndication & Ownership Terms
JV structures, LLCs, sponsors, limited partners, preferred returns, waterfalls & capital calls
Sponsor / GP vs. Limited Partner (LP)
The GP is the active party โ finds, acquires, operates, and exits the property. The LP is the passive investor who contributes capital, earns distributions, and has liability limited to their investment.
Preferred Return (Pref)
The minimum return LPs receive BEFORE the sponsor earns any profit share โ typically 6โ8% annually. It protects passive investors and ensures the GP is incentivized to perform above the hurdle.
Waterfall Distribution
The ordered structure of profit distribution: 1) Return all invested capital โ 2) Pay LP preferred return โ 3) Split remaining profits (e.g., 70% LP / 30% GP "promote"). This order is sacred.
PPM โ Private Placement Memorandum
A disclosure document required by the SEC for Reg D syndication offerings. Outlines the deal structure, risks, investor rights, and terms. A legal document โ you need an attorney to prepare it.
