One person looking for rental properties in Fort Worth calculated their return on investment using Excel, but they completely omitted the management fees that would be required if they hired a management company. To put it simply, they calculated their net income by subtracting only taxes and insurance from their rental income. This case highlights how the actual amount you take home can vary significantly depending on whether you manage the property yourself or hire a management company.

Looking at the rental market in Fort Worth, as of August 2026, the average rent is around $1,900 (steadily.com). At the same time, the average home value is $298,353, which has decreased by 2.0% over the past year (Zillow Home Value Index, as of July 31). Property taxes in Tarrant County have an effective tax rate of 1.77%, meaning that for a home valued at around $290,000, you would pay over $5,200 in taxes annually.

The total return on investment, calculated by dividing the annual rental income of $22,800 by the purchase price, is 7.64%. While this number seems decent at first glance, the issue lies in the fact that this calculation excludes management fees. Typically, if you hire a management company, you would need to pay a commission of about 8 to 12% of the rental income, which means that for a rental property with a monthly rent of $1,900, an additional $150 to $230 would be deducted each month for management fees.

If you apply the 50% rule and estimate total operating expenses to be about half of the rental income, the net operating income would be $11,400 annually, and the cap rate would drop to 3.82%. This includes property taxes, insurance, maintenance costs, management fees, and vacancy losses. When comparing the scenarios of managing the property yourself versus hiring a management company, the difference is that while you save on management fees, you invest more time and effort.

When you factor in the mortgage, the situation changes again. Assuming a 25% down payment and closing costs, the actual investment amount would be around $83,500, and if you borrow the rest at an interest rate in the 7% range, the annual repayment amount would exceed the net operating income, resulting in a negative cash-on-cash return. In simpler terms, in the current interest rate environment, it may be more advantageous for cash flow to make a larger down payment or look for properties priced below market value rather than taking out a loan at the purchase price.

Fort Worth has many neighborhoods with lower purchase prices compared to Dallas, so the total return on investment tends to be decent. However, the trend of increasing purchase prices in areas with good school districts is similar to other major cities. When looking at school districts preferred by Korean families, it's advisable to refer to ratings from GreatSchools or Niche, but keep in mind that school district boundaries change frequently, so it's best to verify the assigned school before making a purchase.

To summarize, when calculating rental income, it's best to follow three steps in order. First, look at the big picture with the total return on investment, then review the cap rate that includes property taxes, insurance, and management fees, and finally, check the cash-on-cash return that reflects the loan conditions to see the actual money left in hand. In markets like Fort Worth, where purchase prices are relatively low, the gap between these three numbers tends to be less pronounced than in Dallas or Plano, but the principle remains the same: omitting just the management fees can change the amount you take home each month.

It's also important to consider the total return perspective that includes mortgage principal repayment and appreciation. Even if the cash-on-cash return appears negative at first, as you pay down the principal each month and add appreciation, the situation could change in a few years. When deciding whether to manage the property yourself or hire a management company, it's wise to consider your available time and the distance from your residence.

Fort Worth is an area of interest for those starting their rental investment journey due to its lower entry prices compared to Dallas. However, if you overlook management fees or vacancies simply because the entry price is low, it could lead to a situation where the net operating income is lower than expected, as seen in this case. In simpler terms, the lower the purchase price, the greater the relative impact of each small cost item on the return on investment.
