A client reviewing rental properties in Kansas City, KS, mixed up the concepts of total income and cap rate that they saw on a real estate YouTube channel. They concluded that the cap rate was excellent based on the total income, which included appreciation and loan principal repayment. However, the cap rate only considers the net operating income for that year, excluding appreciation and principal repayment. While this could be advantageous for investment decisions, misunderstanding it could lead to overestimating immediate cash flow.

As of July 2026, the average rent in Kansas City, KS, is $1,225, with two-bedroom units averaging around $1,267. This is about 37 percent lower than the national median rent of $1,950. Looking at purchase prices, the median sale price as of July 2026 is $235,000, while the current median listing price is $249,000. When considering the entire state of Kansas, the median price rises to around $280,000, making Kansas City, KS, relatively lower.

Calculating based on a two-bedroom unit, the total return rate is 6.47 percent, derived from an annual rental income of $15,204 divided by the purchase price of $235,000. While this figure appears attractive, it does not account for operating expenses such as property taxes, insurance, management fees, maintenance costs, and vacancy losses. The effective property tax rate in Kansas ranges from 1.21 percent to 1.48 percent, which could ease the burden due to lower rents but also serves as a variable that can erode net income, necessitating a balanced view of both aspects.

Applying the 50 percent rule, if we estimate operating expenses at half of rental income, the NOI would be around $7,600 annually, resulting in a cap rate of approximately 3.23 percent when divided by the purchase price. This is about half of the total return rate of 6.47 percent, indicating that this cap rate assumes a cash purchase without financing. The excellent cap rate mentioned by the client was actually a mixed concept of total income that included appreciation and principal repayment, revealing why misunderstandings occurred when comparing the two figures.

If financing is utilized, the cash-on-cash return must also be considered. This metric calculates pre-tax cash flow relative to the actual cash invested, such as down payments and closing costs, and can be more favorable or unfavorable than the cap rate depending on the level of leverage used. If the interest burden is high, cash-on-cash may be lower than the cap rate, while effective use of leverage at lower rates could yield a cash-on-cash return higher than the cap rate.

When recalculating with a three-bedroom unit, the rent rises to $1,538, leading to an annual rental income of $18,456 and a total return rate of 7.85 percent. The variation in total return rates by unit size occurs because the rent increase relative to the purchase price is not consistent across unit sizes, which is worth checking when comparing listings.

Kansas City, KS, has a rental market where 48 percent of rentals fall between $1,001 and $1,500, indicating a relatively uniform rent price range. This is advantageous for expecting stable tenant demand, but it may also limit rent growth potential. Areas preferred by Korean families often have higher purchase prices, so it's advisable to check school ratings on GreatSchools or Niche, as school district boundaries frequently change, and verify the assigned school for the specific address before purchasing.

If moving from another state to Kansas, it's wise to factor in that property tax rates may feel higher than in the previous state. The total return rate, cap rate, and cash-on-cash return answer different questions, so it's beneficial to review all three in sequence rather than making a judgment based on just one.
