What is Office Space Cost Comparison?
A lease vs buy analysis compares total costs of leasing versus purchasing office space over 5-15 years including maintenance, tax, and capital appreciation.
The Formula
Lease TCO = Annual Rent ร Years + Service Charges Buy TCO = Purchase + Maintenance โ Appreciation
Worked Example
A 2,000 sqft office: lease at $35/sqft/year or buy at $500,000 with 65% commercial mortgage.
- Lease 10-year: $70,000 ร 10 + $60,000 CAM/taxes = $760,000
- Buy 10-year: $500,000 + $175,000 interest + $100,000 maintenance = $775,000
- Property appreciation (3%/yr): $500,000 โ $672,000
- Buy net cost: $775,000 โ $172,000 gain = $603,000
๐ Buying saves $157,000 over 10 years through equity building, but requires $175,000 down payment and long-term commitment.
Why This Matters
Capital building
Monthly mortgage payments build equity worth $75,000-250,000 over a decade. Rent builds nothing.
Flexibility trade-off
Leasing allows relocation as the business grows. Buying locks capital and location for 10+ years.
Tax implications
Lease payments are fully deductible as business expenses. Ownership uses depreciation (including Section 179 and bonus depreciation) and capital gains rules differently.
Common Mistakes
โ Comparing rent to mortgage only
Ownership includes maintenance, insurance, and property taxes on top of mortgage. Compare total occupancy costs.
โ Ignoring flexibility needs
Fast-growing companies may outgrow premises in 2-3 years. A 10-year buy commitment becomes an anchor.
โ Not modeling scenarios
Property values can decline. Model flat and declining scenarios alongside growth to understand downside risk.
