Leasing Extra Space: Generating Income from Your Commercial Property

Maximizing Your Commercial Property's Potential

When you purchase a commercial property for your business, you may end up with more space than you currently need. Rather than letting that space sit empty, leasing it out can generate valuable income to offset your ownership costs.

Understanding Lease Structures

Triple Net (NNN) Leases

What it means: The tenant pays base rent plus all operating expenses:

Property taxes
Insurance
Maintenance and repairs
Common area maintenance (CAM)

Advantages for property owners:

Predictable income with minimal expense responsibility
Tenant handles most property costs
Easier property management
Typically longer lease terms

Disadvantages:

Lower base rent compared to gross leases
Tenant must be creditworthy to handle expenses
Complex lease agreements

Gross Leases

What it means: The owner pays all operating expenses; tenant pays a fixed rent.

Advantages for property owners:

Control over property maintenance and appearance
Can charge higher rent

Disadvantages:

Expenses may rise faster than rent

Modified Gross Leases

What it means: A hybrid where expenses are shared between owner and tenant.

Flexibility in structuring the deal
Can allocate expenses fairly
Market-friendly for many tenants
