How the math works
Occupied = units × uptake × (1 − vacancy). Monthly = occupied × rent.
40 × 85% × 95% = 32.3 × $65 = $2,100/mo = $25k/yr. At 5% = $500k value.
How to Use
- Enter storage units available.
- Enter monthly rent per unit.
- Enter uptake %.
- Enter vacancy %.
- Read annual storage income.
Frequently Asked Questions
Typical rents?
5x5 (25 SF): $30-50/mo. 5x10 (50 SF): $50-75. 10x10 (100 SF): $75-125. Suburban: lower. Urban: premium. Enclosed more than outdoor. Climate-controlled 20-30% premium.
Uptake?
Available when demand identified: 70-85% typical. Waitlist common in dense markets. 20-unit storage program on 200-unit property captures $8k-15k/mo NOI. Often oversubscribed.
Economics?
Cost per storage unit: minimal once built. $30/mo × 20 units × 85% uptake = $510/mo NOI. $6k/yr × 200-unit property = $30/unit NOI. Small but meaningful; low-effort amenity.
How often should I rerun this?
Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
