Learn practical techniques to supercharge your productivity and get more done in less time

Want to break into self-storage investing? Start here. This guide cuts through the complexity of self-storage underwriting to deliver exactly what you need to know—no fluff, just actionable insights backed by real data.
Why Self-Storage Is Different (And Why It Matters)
Unlike traditional real estate, self-storage operates on month-to-month contracts with unique market dynamics. Key differentiators:
- Flexible lease terms that require constant market adjustments
- Demand driven by life events and population shifts
- Operating costs 30-35% lower than traditional real estate
- Recession-resistant income streams
- Predictable seasonal patterns you can leverage
Essential Metrics: What Actually Matters
1. Occupancy Analysis
Top-performing facilities maintain 85-95% occupancy, but raw numbers don't tell the whole story. Track these metrics:
- Economic vs. physical occupancy (they can differ by up to 15-20%)
- Move-in/move-out velocity
- Seasonal demand patterns
- Long-term tenant mix composition
2. Revenue Deep Dive
Your revenue analysis must cover:
- Street rates vs. actual collected rents
- Impact of promotional discounts
- Ancillary income opportunities
- Seasonal pricing adjustments
- Market rate positioning
3. True Expense Understanding
Know your actual costs:
- Property taxes: Expect potential reassessment risk
- Insurance: $0.25-$0.40 per square foot
- Marketing: $1,000-$3,000 monthly
- Staffing: On-site vs. automated solutions
- Maintenance: Regular requirements and reserves
Common Rookie Mistakes (And How to Avoid Them)
- Over-relying on Market Averages
- Solution: Analyze facility-specific performance metrics
- Action: Create custom performance benchmarks for your market
- Misunderstanding Expense Ratios
- Reality: Expect 30-35% of revenue for standard facilities
- Warning: Higher for older properties, lower for automated ones
- Ignoring Seasonality
- Fact: Summer occupancy can spike 15-20% above winter levels
- Action: Build seasonal adjustments into your revenue models
