Understanding cash flow is one of the most essential parts of being a successful real estate investor. After all, cash flow tells you whether your rental property is actually making money each month or actually costing you more than you realize. So, whether you’re analyzing a potential investment or evaluating an existing rental, knowing how to calculate cash flow is crucial. Today, we’ll review what cash flow is, what to include, and how to calculate your cash flow so you can make smarter investment decisions.
What Is Cash Flow in Real Estate?
In real estate, cash flow refers to the money left over after all rental income is collected and all operating expenses are paid. In simple terms, it’s the profit (or loss) your rental generates each month.
The goal for any investor is obviously positive cash flow, although it doesn’t always go that way. Positive cash flow means that your rental earns more than it costs to operate. On the other hand, negative cash flow means you’re paying out of pocket to keep the property running.
It’s important to know how much income you’re receiving and how much you’re spending on expenses so you can monitor your cash flow and avoid going negative. This is especially important in competitive markets like Austin, where working with experienced Austin, TX property management teams can help you stay on top of income, expenses, and your rental’s overall performance.
What to Include in Your Cash Flow Calculation
To accurately calculate cash flow, it’s crucial that you include all income and all expenses–not just the obvious ones like rental income or maintenance expenses. That said, here are some of the main points to consider for your calculation.
Rental Income
Monthly rent payments
Security deposits
Rental fees
Pet rent
Parking fees
Storage or garage rental fees
Operating Expenses
Mortgage payment
Property taxes
Insurance
Maintenance and repairs
Property management fees
HOA dues
Utilities (if owner paid)
Vacancy allowance
Long-term repairs like roofs or HVAC systems
The Formula for Calculating Rental Cash Flow
The formula for calculating cash flow is pretty straightforward. You just have to know your total monthly rental income and your total monthly expenses. Then, you subtract your expenses from your total income. Here’s how it looks.
Cash Flow = Total Monthly Rental Income - Total Monthly Expenses
Here’s a quick example of how it works:
Say you charge $2,400/month for your rental property.
Monthly Rental Income: $2,400
Now, let’s say you have the following monthly expenses for your rental:
Mortgage: $1,350
Taxes: $250
Insurance: $125
Property Management: $240
Utilities: $100
Monthly Rental Expenses: $2,065
Monthly Income $2,400 - Monthly Expenses $2,065 = Monthly Cash Flow $335
In this scenario, the property generates $335 in positive cash flow each month. Over a year, that equals $4,020 before taxes. This is great because the property is profitable, and anything above $100 to $200 per month per unit is considered a good monthly cash flow.
While it’s not always perfect, investors can use this basic calculation as a starting point, and then dig deeper by analyzing things like cash-on-cash return, cap rate, and long-term appreciation potential.
Common Mistakes Investors Make When Estimating Cash Flow
While cash flow is usually just an estimation, it’s crucial to have a general idea of how much your rental makes each month. That said, even the most experienced investor can miscalculate cash flow. All it takes is forgetting one important aspect, and your numbers are all off.
If you want to calculate cash flow correctly, here are some mistakes you’ll want to avoid.
Ignoring vacancy costs
Underestimating maintenance costs
Forgetting long-term expenses, like roof replacements, plumbing issues, or HVAC problems
Overestimating rent instead of using real market data
Cash flow estimates don’t have to be perfect, and it’s impossible to predict every expense. However, they should be realistic. That said, it’s important to take the time to account for things like vacancies, maintenance expenses, and long-term repairs, even if they’re not necessarily a priority. That way, you can avoid any unpleasant surprises and make better investment decisions.
How to Improve Cash Flow on Your Rental Property
If your cash flow isn’t where you want it to be, there are several ways to improve it. Some of the best ways to do so include the following.
Add Value to the Property - One of the best ways to increase your monthly cash flow is to add value to the property through upgrades and renovations. For instance, you may consider updating lighting fixtures, buying new appliances, or adding smart technology to your property so you can charge higher rates.
Raise Rent Prices Slightly - Rental rates typically increase over time as inflation grows. So, it’s essential to stay up-to-date with current market values so you don’t miss out on potential profits. That said, it’s also important to ensure rates are fair and aligned with comparable rentals in the area.
Work to Reduce Vacancies - Vacant properties are a property owner’s worst nightmare. After all, if there’s nobody paying to live there, that means you, as the owner, are paying all of the expenses. Without a solid process for finding and keeping qualified tenants, you could lose out on a ton of profits.
Reduce Operating Costs - Finally, another way you can increase cash flow is by reducing operating expenses. Luckily, there are a few ways you can do this. For instance, you can shop around to find the best prices for insurance, maintenance vendors, and property management services.
