What Is a Multifamily Cap Rate?
A capitalization rate estimates annual net operating income, or NOI, as a percentage of a property’s value or purchase price.
Cap Rate = Net Operating Income ÷ Property Value
NOI is property income minus normal operating expenses. It does not include mortgage payments, income taxes, depreciation, or major capital projects.
The original BFPM article uses the same method: subtract operating expenses from income, then divide by the property’s cost. A cap rate calculator can make the math faster, but the result is only as reliable as the income and expense figures entered.
Cap Rate Calculation Examples
Example 1: Stabilized Apartment Building
Assume a property has:
- Purchase price: $5,000,000
- Annual gross income: $500,000
- Operating expenses: $225,000
- NOI: $275,000
The calculation is:
$275,000 ÷ $5,000,000 = 5.5%
This apartment cap rate shows the property’s annual unlevered return before financing and taxes.
Example 2: Value-Add Property
A $4,000,000 property currently produces $180,000 in NOI:
$180,000 ÷ $4,000,000 = 4.5%
After renovations, projected NOI may rise to $240,000:
$240,000 ÷ $4,000,000 = 6.0%
The second figure is a projected cap rate, not a guaranteed return. Investors must also budget for renovations, vacancy, construction delays, and local rent restrictions.
Current Multifamily Cap Rates by Market
Recent reports show how much location changes the answer to “What is a good cap rate for multifamily?”
- United States: Apartment transactions averaged 5.7% in 2025.
- Los Angeles: The average multifamily cap rate was 5.1% in Q1 2026.
- Orange County: The Q1 2026 average was 4.5%.
- San Diego: Average cap rates reached 5.0% in Q1 2026.
- Inland Empire: The average was 6.0% in Q2 2026.
These figures are market averages, not targets for every deal. Orange County’s lower cap rate reflects high pricing, limited supply, strong occupancy, and continued investor interest. The Inland Empire’s higher average may provide more income relative to price, but properties can carry different operating and neighborhood risks.
How Cap Rates Vary by Property Type
Class A Properties
Newer properties in strong locations often have lower cap rates. Buyers may accept a lower initial return because they expect stable occupancy, fewer repairs, and stronger long-term value.
Class B Properties
Class B communities often trade in the middle. They may provide a balance between current cash flow and opportunities for unit upgrades or operating improvements.
Class C Properties
Older buildings or properties in less stable areas often have higher cap rates. The added return may reflect deferred maintenance, collection problems, insurance costs, or heavier management needs.
Stabilized and value-add properties also require different calculations. CBRE defines stabilized cap rates using stabilized NOI. Value-add analysis considers expected income after improvements and the additional capital needed to complete them.
Factors That Affect Cap Rates
When determining whether a property offers a good cap rate multifamily investors should examine:
- Location and renter demand
- Property age and physical condition
- Current rents compared with market rents
- Vacancy and collection history
- Insurance, utilities, payroll, and repair costs
- Interest rates and available financing
- Rent control and tenant protection requirements
- Renovation and future capital needs
A higher multifamily cap rate can mean stronger income, but it may also signal greater risk. A lower rate may reflect a desirable location or stronger growth expectations, but it can also mean the buyer is paying a premium.
Cap Rate vs. ROI and Cash-on-Cash Return
These real estate investment metrics answer different questions.
Cap rate compares NOI with the property’s price and ignores financing.
Return on investment, or ROI, compares the total gain with the total amount invested. It may include cash flow, appreciation, sale proceeds, and renovation gains.
Cash-on-cash return compares annual pre-tax cash flow with the investor’s actual cash investment. Unlike cap rate, it includes the effect of loan payments.
For example, an investor puts $1,250,000 down on a $5,000,000 property. After operating expenses and debt payments, annual pre-tax cash flow is $100,000.
$100,000 ÷ $1,250,000 = 8% cash-on-cash return
A property can have a 5.5% cap rate and an 8% cash-on-cash return because financing changes the return earned on invested cash.
The Bottom Line
A good cap rate for multifamily property should match the building’s risk, location, condition, and investment plan. Market averages are helpful, but careful underwriting is more important than chasing one percentage.
