Key Takeaways
- Net Operating Income (NOI): Profit before mortgage (Gross Rental Income – Operating Expenses). Positive NOI shows a healthy property.
- Cap Rate: Return relative to property value (NOI ÷ Property Value × 100). Good for comparing properties.
- Cash Flow: Money left after all expenses (Rental Income – Operating Expenses – Mortgage). Positive cash flow ensures stability.
- Cash-on-Cash Return: Return on invested cash (Annual Cash Flow ÷ Total Cash Invested × 100). Higher is better.
- Occupancy/Vacancy Rates: Measure rented vs. empty units. High occupancy, low vacancy indicate strong demand.
- Operating Expense Ratio (OER): Expense efficiency (Operating Expenses ÷ Gross Rental Income × 100). Keep below 50%.
- Debt Service Coverage Ratio (DSCR): Income vs. debt payments (NOI ÷ Annual Debt Service). Above 1.2 is safe.
- Actionable Insight: Track these metrics to optimize returns and spot issues early. Consider professional management like TE Johnson & Sons for support.
Do you know how to tell if your rental property is truly performing well? Many landlords keep an eye on rent payments and maintenance issues, but that’s only part of the picture.
If you’re not tracking the right figures, you might miss early signs of financial trouble or overlook ways to increase your returns.
To help with this, TE Johnson & Sons put together this article explaining the most important real estate metrics every landlord should understand.
Key Real Estate Metrics Landlords Should Monitor
1. Net Operating Income (NOI)
Net Operating Income (NOI) is one of the most basic and essential metrics. It shows how much money your property earns after covering all regular operating expenses, excluding your mortgage.
Formula: NOI = Gross Rental Income – Operating Expenses
A positive NOI means the property is generating income before debt payments.
2. Capitalization Rate (Cap Rate)
Cap Rate helps you evaluate a property's profitability relative to its value. It’s commonly used to compare different properties or decide if a purchase price is reasonable. A higher cap rate often indicates a higher return, but possibly more risk.
Formula: Cap Rate = (NOI ÷ Property Value) × 100
Cap Rates vary by market and property type, so use it mainly to compare similar properties in the same area.
3. Cash Flow
Cash flow shows how much money is left after paying for all expenses, including the mortgage. This is the money that actually ends up in your bank account each month.
Formula: Cash Flow = Rental Income – (Operating Expenses + Mortgage Payments)

A positive cash flow means your property earns more than it costs to own. Negative cash flow can be a warning sign that changes are needed.
4. Cash-on-Cash Return
Cash-on-Cash return measures the return you’re getting on the actual cash you invested, such as your down payment and renovation costs.
Formula: Cash-on-Cash Return = (Annual Cash Flow ÷ Total Cash Invested) × 100
If you invested $50,000 and are earning $5,000 per year in cash flow, your return is 10%. Higher percentages usually mean better returns on your invested money.
5. Gross Rent Multiplier (GRM)
The GRM is a simple tool for evaluating whether a property’s price makes sense based on the rent it brings in. It doesn’t consider expenses, so it’s not a final decision tool, but it’s useful for screening properties.
Formula: GRM = Property Price ÷ Annual Gross Rent
Lower GRMs generally suggest a better deal, assuming similar operating costs. For example, a property costing $200,000 that generates $24,000 in rent has a GRM of 8.3.
6. Occupancy Rate
This metric shows how often your units are rented out. A high occupancy rate means fewer gaps in rental income. It’s especially important for multi-unit buildings.
Formula: Occupancy Rate = (Rented Units ÷ Total Units) × 100
If you have 10 units and 9 are rented, your occupancy rate is 90%. Consistently low occupancy may mean rent is too high, or the property needs improvements.
7. Vacancy Rate
This is the opposite of the occupancy rate and shows how often your units are empty and not earning money. It’s another sign of the health of your rental business.
Formula: Vacancy Rate = (Vacant Units ÷ Total Units) × 100
A vacancy rate that’s too high can mean problems attracting or keeping tenants. Aim to keep this as low as possible.
8. Operating Expense Ratio (OER)
This metric shows what portion of your rental income is going toward expenses. It helps measure how efficiently you’re operating.
Formula: OER = (Operating Expenses ÷ Gross Rental Income) × 100
If your OER is too high, it could mean costs are eating up too much of your income. Ideally, you want this number to be lower than 50%, depending on your market and property type.
9. Rent-to-Value Ratio (RTV)
RTV helps you estimate how much income a property generates relative to its market value. It’s helpful when comparing different investment opportunities.
Formula: RTV = (Monthly Rent ÷ Property Value) × 100
For example, if a property worth $200,000 rents for $1,800 a month, your RTV is 0.9%. Many investors look for properties with an RTV between 0.8% and 1.2%.
10. Break-Even Ratio
This metric shows how much of your income goes toward covering operating expenses and debt. It helps assess how much cushion you have before you start losing money.
Formula: Break-Even Ratio = (Operating Expenses + Debt Payments) ÷ Gross Income
A break-even ratio above 85% means most of your income is covering costs, leaving little room for unexpected expenses. Lower ratios are safer.
11. Return on Investment (ROI)
ROI measures your total return over time, including appreciation, income, and any gains from selling the property.
Formula: ROI = (Net Profit ÷ Total Investment) × 100
It gives you a long-term view of how well your investment performed, not just monthly cash flow.
12. Debt Service Coverage Ratio (DSCR)
This shows whether your income is enough to cover your debt payments. It’s a ratio lenders often look at when evaluating risk.
Formula: DSCR = NOI ÷ Annual Debt Service
A DSCR of 1.2 means you earn 20% more than your debt payments. Ratios below 1.0 mean you are not making enough income to cover your loan.
13. Tenant Estoppel Certificate
A tenant estoppel certificate is a legal document signed by a tenant to confirm the key terms of their lease, such as rent amount, security deposit, and lease duration, as of a specific date. It provides assurance to buyers, landlords, and lenders that the lease information is accurate, helping prevent future disputes or misunderstandings during a property sale or transfer.
