Understanding What Is Cash Flow

In order to be a successful real estate investor, you must know some basic financial terms and concepts.

Cash flow is a crucial term in real estate, but what does it really mean? Simply put, cash flow is the money left over after covering all the expenses related to your rental property.

To calculate it, subtract costs like mortgage payments, property taxes, insurance, and maintenance from the rental income you receive.

If there’s money remaining, you have positive cash flow; if not, you’re dealing with negative cash flow. In essence, cash flow is a key metric for determining whether your investment is profitable or losing money.

Cash flow is vital because it directly reflects a property’s financial health. Positive cash flow indicates profitability, providing funds that can be reinvested or saved.

It also ensures you have a cushion for unexpected costs, such as repairs or vacancies, without compromising your financial stability.

For successful investors, consistent cash flow is the foundation of wealth-building and long-term financial security.

How to Calculate Cash Flow

The cash flow of a rental property is calculated by subtracting your total expenses from your gross income. Here’s exactly what this entails:

Step 1: Determining Your Gross Rental Income

To calculate your property’s gross rental income, start by adding up all the rental payments the unit generates over a month.

Include additional income sources such as parking fees, storage charges, pet fees, or laundry services.

Once you have the monthly total, multiply it by 12 to determine the annual gross rental income. This figure represents the total income your property produces in a year.

Step 2: Identifying Your Operating Expenses

The second step to calculating your rental property’s cash flow is to add up all of your expenses.

Start by listing all expenses required to operate the property. Common operating expenses include:

  • Property taxes
  • Insurance premiums
  • Maintenance and repair costs
  • Utilities (if you cover them)
  • Property management fees
  • HOA fees (if applicable)

Add up these costs to determine the total annual operating expenses. If your property is financed, you must also factor in the annual cost of mortgage payments (principal and interest).

This expense is critical to the calculation as it impacts your net profitability.

Step 3: Accounting for Miscellaneous Expenses

Sometimes unexpected expenses may come up, whether it’s an emergency repair or periods of vacancy.

You can estimate these potential expenses and set aside a percentage of income (usually 5%-10%) as a buffer.

Include other costs, such as legal fees, advertising, or accounting services for a more realistic result.

Step 4: Calculating Your Total Expenses

Add up your operating expenses, mortgage payments, and other miscellaneous expenses to determine your total annual expenses.

Step 5: Subtracting the Total Expenses from the Gross Income

The formula for calculating cash flow is very simple: Cash Flow = Gross Rental Income - Total Expenses.

By subtracting your total expenses from your gross rental income, you’ll determine your property’s cash flow.

This figure represents the annual net income your property generates. You can divide it by 12 to see how much cash flow your investment is generating on a monthly basis.

This will help you assess whether your investment is performing as you expected.

How to Improve the Cash Flow of Your Rental Property

Negative cash flow occurs when your expenses exceed rental income, straining your finances and reducing long-term profitability.

In severe cases, it could even force a sale or additional debt. If you're facing negative cash flow, here are 8 strategies to improve your rental property’s financial performance:

  • Set Competitive Rental Rates: Research the local market to ensure your rent is competitive and adjust it regularly to match trends.
  • Reduce Operating Expenses: Cut costs by negotiating insurance premiums, using energy-efficient appliances, or performing preventive maintenance.
  • Minimize Vacancy Periods: Market your property early and encourage lease renewals to avoid lost income from vacancies.
  • Screen Tenants Thoroughly: Choose reliable tenants who pay on time and care for the property, reducing late payments and damage.

  • Refinance Your Mortgage: If interest rates drop, refinancing can lower monthly payments, improving cash flow.
  • Offer Additional Services: Add paid amenities like laundry, parking, or furnished units to boost income.
  • Leverage Tax Benefits: Maximize deductions for property taxes, insurance, and depreciation to reduce costs.
  • Partner with a Property Manager: A skilled manager can improve rent collection, tenant retention, and vacancy rates, boosting your cash flow.
