Step 3: Work through a simple example

Imagine a property earns $2,400 per month. After setting aside $1,500 for the mortgage, $250 for taxes and insurance, $200 for maintenance, $100 for utilities, and $150 for vacancy, the estimated monthly cash flow is $200. Repeat the calculation for each property and review it monthly.

Step 4: Use cash flow to make decisions

Cash flow is more useful when you compare it over time. It helps you spot rising costs, plan repairs, evaluate rent changes, and decide whether a potential purchase fits your investment plan. Keep income and expenses organized so your numbers remain current.

A simple, consistent cash flow routine makes rental performance easier to understand. Track the numbers each month, keep a reserve for the unexpected, and use clear reports to make your next decision with confidence.

Rental property cash flow is the money left after you collect income and pay every operating and financing cost. It is one of the clearest measures of whether a rental is supporting your goals or quietly draining your budget.

The basic cash flow formula

Monthly cash flow = total rental income - total monthly expenses. Positive cash flow means income is higher than expenses. Negative cash flow means you need to cover the difference from other funds.

Step 1: Add up monthly income

Start with the rent you actually expect to receive, not only the advertised amount. Include parking, storage, pet fees, laundry income, or other recurring revenue. Then allow for vacancy and late-payment risk so your estimate stays realistic.

Step 2: List every monthly expense

Include mortgage principal and interest, property taxes, insurance, utilities, management fees, repairs, maintenance, and a reserve for large future costs. The more complete your list, the more useful the result.
