What is the 1% rule for commercial property?

The 1% rule for commercial property is a general guideline some investors use to quickly evaluate whether a property could generate positive cash flow, although it’s much more common in residential real estate. For commercial properties, it works a bit differently due to higher costs, leases, and expenses. Here’s a breakdown:


Basic Idea

The 1% rule suggests that a commercial property’s monthly rental income should be at least 1% of its purchase price.

Formula: Monthly Rent≥1%×Purchase Price\text{Monthly Rent} \geq 1\% \times \text{Purchase Price}Monthly Rent≥1%×Purchase Price

Example:

  • Commercial building purchase price: $500,000
  • 1% of $500,000 = $5,000
  • Monthly rent should be at least $5,000 to meet the 1% rule

Why It’s Useful

  • Quick screening: Helps investors filter properties without detailed financial modeling.
  • Cash flow estimate: Provides a rough idea of whether rent could cover mortgage, taxes, and expenses.

Limitations

  • Commercial leases vary: Triple-net (NNN), gross, or modified leases affect actual cash flow.
  • Expenses are higher: Maintenance, property management, insurance, and vacancies can eat into the 1%.
  • Not a strict rule: Many successful investors ignore it and rely on more detailed metrics like cap rate, cash-on-cash return, and NOI (Net Operating Income).

Here’s a simple table showing how the 1% rule roughly applies to different types of commercial properties.

Keep in mind these are general guidelines—actual rents and expenses can vary widely.

Property TypePurchase Price Example1% Monthly Rent TargetNotes
Office Building$500,000$5,000Higher vacancy risk; consider long-term leases.
Retail Space$750,000$7,500Foot traffic and tenant type heavily influence rent.
Industrial/Warehouse$600,000$6,000Lower maintenance costs; often more stable tenants.
Multi-Family (Commercial Units)$1,000,000$10,000Easier to achieve 1% due to multiple units; watch management costs.

Key Points:

  • The 1% rule is just a quick screening tool, not a full financial analysis.
  • Always factor in vacancy rates, operating expenses, taxes, and financing costs.
  • For commercial property, metrics like cap rate and cash-on-cash return are usually more accurate.
