Last month, a client looking for rental properties in Fargo asked if a cap rate of 8 percent meant that the cash flow would be that much as well. After calculating two properties with similar conditions, it became clear that they were confusing cap rate with cash-on-cash return. In areas like Fargo, where the rent is relatively low compared to the purchase price, the difference between these two metrics can be significant, making it important to distinguish them from the start.

The average value of homes in Fargo is about $291,493 according to Zillow (as of 2026, with a 3.7 percent increase over the past year). The average rent is $1,125 per month according to Zumper (as of August 2026), and based on these two figures, the total return calculates to an annual rental income of $13,500 divided by the purchase price, resulting in about 4.65 percent. However, the issue does not end there.

The cap rate is recalculated based on net operating income, which subtracts operating expenses such as property taxes, insurance, management fees, and vacancy losses. The average effective property tax rate in North Dakota is about 0.99 percent (as of 2026), meaning that for a home valued around $290,000, the annual property tax would be approximately $2,871. When adding insurance, maintenance costs, and vacancy losses, applying the 50 percent rule, the net operating income would drop to around $6,750 per year. Dividing this by the purchase price gives a cap rate of about 2.3 percent, which is nearly half of the total return of 4.65 percent.

When factoring in cash-on-cash return with a mortgage, the story changes. If the actual cash invested, including down payment and closing costs, is around $60,000, the pre-tax cash flow remaining after paying the mortgage principal and interest must be divided by this $60,000. Using leverage can result in cash-on-cash returns that are either higher or lower than the cap rate. Since the direction depends on interest rates and loan-to-value ratios, relying on just one of these three metrics can easily lead to confusion, as seen with that client.

One often overlooked aspect when comparing returns is the concept of total return. While cap rate and cash-on-cash return only show the cash flow coming in each month, the actual investment performance must also account for appreciation, repayment of the loan principal, and tax benefits from depreciation to be fully revealed. Even in areas like Fargo, where the cap rate is low at around 2 percent, the gradual increase in assets due to some of the principal repayment each month, along with potential future appreciation, can change the overall picture. However, appreciation cannot be guaranteed as it varies based on local economic conditions and population trends.

When comparing Fargo with neighboring West Fargo, the differences become even clearer. Both areas have similar rental levels, but slight differences in purchase prices and property tax assessment methods mean that it's wise to evaluate which area offers a better cap rate for the same budget. While the overall rental demand in the Fargo-Moorhead metro area is generally stable, it's important to check the recent rental turnover rates for individual properties, especially during times of increased new supply, as vacancy rates may temporarily rise.

In the past, observing the Fargo rental market for just a few years made trends apparent, but recently, fluctuations in interest rates and construction costs have increased regional disparities. Therefore, it seems effective to first filter properties based on total return, then assess actual operational burdens through cap rate, and finally incorporate loan conditions with cash-on-cash return to make a final decision. Checking if the rent is around 1 percent of the purchase price, as a rule of thumb, can also be helpful.

If you are also looking into areas preferred by the Korean community, it is advisable to consider not only cash flow but also school district ratings. However, since school district boundaries frequently change, it's best to verify the assigned school for a given address through GreatSchools or state education department resources before making a purchase. Property tax rates and rental regulations can vary by county, so it's also wise to take this into account.
