Before diving into investments, you need to fully understand what cash flow in real estate is all about. Cash flow is the net amount moving in and out of your real estate investment—obviously, an important number to keep track of. It gives a metric for how an investor will know the profitability of a property. Without understanding cash flow, you might have a property that is losing money rather than profiting. Let us take a closer look at what cash flow from real estate is, its importance, how to measure it, drivers, and tips to increase it.

What Is Cash Flow in Real Estate?

Cash flow in property investment simply refers to the difference between the money you take in and what you spend. Positive cash flow means your income exceeds your expenses, and negative cash flow indicates the opposite. 

It’s a very simple concept but fundamental to real estate investment practices. A positive cash flow will provide an investor with continuous income and financial stability to reinvest in more properties. Understanding cash flow from real estate will help you make informed buying, holding, and selling decisions regarding property.

Why Do Investors Care About Cash Flow From Real Estate?

Cash flow is the lifeblood of real estate investing. It will dictate whether the property will become a financial liability or an asset. Consistent cash flow can provide for mortgage, maintenance, and other expenses. This padding in your bank account will help safeguard against market downturns or other cost surprises. High cash flow properties will also appreciate over time and increase your overall portfolio. The objective of anyone diving into real estate investing is to get the highest return on their investments. 

How to Calculate Cash Flow in Real Estate

Any serious real estate investor must learn to calculate cash flow. The investor will use these equations to understand the property’s profitability and thus be able to make a decent investment decision accordingly. Beyond the cash flow formula, you can use other valuable calculations to enhance the analysis: the CAP rate and the 1% rule. Here are the formulas for the necessary calculations: 

Real Estate Cash Flow Formula

This formula helps determine the profitability of a property by calculating the net income after all expenses.

Cash Flow = Total Rental Income − Total Operating Expenses (Operating Expenses + Vacancy Costs + Repair Costs)

Example of positive cash flow: Imagine you own a rental property that generates $3,000 per month in rental income. Your monthly operating expenses, including mortgage payments, property taxes, insurance, maintenance, and management fees, total $2,000. 

Using the cash flow formula:

$3,000 − $2,000 = $1,000 (Cash Flow)

In this example, the property provides a positive cash flow of $1,000 monthly, indicating a profitable investment. 

Example of negative cash flow: Let’s take the example above with a property generating $3,000 per month in rental income, but now the monthly operating expenses are $4000 because this property has a higher property tax and additional maintenance that must be paid for monthly. 

Using the cash flow formula:

$3,000 − $4,000 = -$1,000 (Cash Flow)

This example showcases a negative cash flow that indicates this wouldn’t be a profitable investment. 

1% Rule Calculation

The 1% rule is a guideline for a quick and easy way to check that the rental income will more than likely pay off most expenses, indicating some possible positive cash flow. Keep in mind that it is an estimation. Here’s how to calculate it:

  • Determine the purchase price: Find out the total cost of the property, including any closing costs and necessary repairs or upgrades.
  • Calculate 1% of the purchase price: Multiply the purchase price by 1%.

Purchase Price × 1% (0.01) = Estimated Cash Flow

Example 1% rule calculation: Suppose you are considering buying a property for $200,000. To apply the 1% rule:

1% of Purchase Price = $200,000 × 0.01 = $2,000 (Estimated Cash Flow)

According to the 1% rule, the property should generate at least $2,000 monthly rental income to be considered a good investment. If the expected rental income meets or exceeds this amount, the property will likely provide positive cash flow, making it a potentially sound investment.

Cap Rate

Using the cap rate formula, also known as the capitalization rate, will be beneficial when comparing the potential return on investment among different properties. This calculation is more complicated and involves a few extra steps. 

Net Operating Income (NOI) / Purchase Price = Cap Rate 

Step 1: Determine net operating income (NOI): Calculate the annual rental income and subtract all operating expenses.

Total Rental Income − Total Operating Expenses = NOI

John owns a rental property that generates $3,000 monthly in rental income, totaling $36,000 annually. His annual operating expenses, which include mortgage payments, property taxes, insurance, and maintenance, amount to $1,000 per month, or $12,000 per year. Calculate his NOI below: 

$36,000 (Rental Income) − $12,000 (Operating Expenses) = $24,000 (NOI)

Step 2: Determine Purchase Price: Find out the total purchase price of the property. The total purchase price can include the property cost, closing costs, inspection fees, and necessary repairs or renovations.

$250,000 (Property Price) + $15,000 (Closing Costs) + $34,600 (Repairs/Renovations) + $400 (Inspection Cost) = $300,000 Purchase Price

Step 3: Calculate the Cap Rate using the above formula (NOI / Purchase Price = Cap Rate)

$24,000 (NOI) / $300,000 (Purchase Price) = 0.08 or 8% (Cap Rate)

In this example, the property has a cap rate of 8%. This percentage means the property generates an 8% return on investment based on its net operating income. A higher cap rate generally indicates a more profitable investment.  

What Factors Affect Cash Flow? 

Several factors may impact cash flow in real estate investing, so it will be important to understand the variables to maintain positive cash flow. Here are the critical elements that influence cash flow most:

  • Expenses: Large negative cash flow items include operating expenses like mortgage payments, property taxes, insurance, maintenance, utilities, and property management fees. Other current and nonrecurring expenses that impact your profitability might include major repairs or emergency maintenance.
  • Rental income: How much you can charge for rent depends on location, property condition, and market demand. High vacancy or high turnover rates lower rental income, hurting cash flow.
  • Rental vacancies: The more vacant a property is, the less rental income will be collected. Effective tenant retention strategies and rigorous screening processes will help minimize vacancies and keep cash flowing.
  • Market conditions: Economic conditions, interest rates, and local real estate markets drive rental rates and property values. Shifts in these can negatively or positively affect cash flow.
  • Property management: Good property management keeps rent collection, maintenance, and tenant relations in check to provide steady cash flow. Poor management increases vacancies and raises expenses, which will cut profit margins.

By keeping these factors in control, investors can have an inflow of cash to make real estate investing profitable and sustainable.
