Short answer：Mini-storage does not guarantee stable cash flow. Fire safety, permitted use, fitting out, management and actual occupancy can matter more than advertised rent per area.
Check safety and use first
FSD identifies fire and escape risks in certain storage layouts. Obtain qualified advice on cubicles, routes, windows, systems and exits alongside lease, planning and building matters. Existing operation does not establish full compliance.
Use lettable area and real occupancy
Circulation and services occupy space. Include vacancy, discounts, security, power, insurance and repairs and clarify responsibility for stored goods. Headline rent multiplied by total floor area is not net income.
Before deciding
- Check improvement notices
- Verify occupancy and collections
- Reserve for alterations and reinstatement
