Let's first look at the case of a Korean investor who purchased a rental condo in Augusta. When crunching the numbers, they assumed that tenants would be fully occupied throughout the year, but in reality, the unit was vacant for two months while the tenant changed, significantly eating into the annual yield. In the past, it was thought that vacancy was not a major issue in markets like Augusta with low rental prices, but now we see through various cases that even a short vacancy can shake the entire yield calculation.

According to RentCafe, as of April 2026, the average rent in Augusta is $1,226 per month, while Zumper estimates it slightly higher at $1,300. The Zillow Home Value Index suggests that the average home value in Augusta is $188,454, which, when used to calculate total yield, results in an annual rental income of $14,712 divided by the purchase price, yielding about 7.8 percent. In markets like Augusta, where the purchase price is low, the total yield figure tends to be quite high.

The problem is that this figure does not take vacancies into account at all. According to Ownwell, the effective property tax rate in Richmond County is about 1.25 percent, meaning that for a $188,454 home, the property tax alone would be around $2,355 annually. When you add insurance, maintenance costs, and vacancy losses during tenant turnover, applying the 50 percent rule reduces the net operating income to about $7,356, which brings the cap rate down to approximately 3.9 percent. This is where the investor's calculations went wrong by underestimating the actual vacancy period.

If financing is involved, the calculations change again. If a down payment and closing costs of $40,000 are invested and the remaining pre-tax cash flow is $2,000 annually after paying the mortgage principal and interest, the cash-on-cash return would be 5 percent. The cash-on-cash return is higher than the cap rate due to the leverage effect, and this figure can decrease if interest rates rise.

• Total yield before accounting for vacancy = annual rental income ÷ purchase price x 100
• Cap rate including vacancy loss = annual NOI ÷ purchase price x 100
• Cash-on-cash return when financing = annual pre-tax cash flow ÷ actual cash invested x 100

According to the 1 percent rule, a home valued at $188,454 should rent for $1,884 per month, but the average rent in Augusta of $1,226 to $1,300 falls short of this benchmark. However, since the purchase price itself is low, the cap rate tends to be relatively favorable. The school district near Columbia County, which is of interest to Korean families, has a high rating on GreatSchools, indicating steady rental demand, but school district boundaries change frequently, so it is advisable to verify the assigned school for the address before signing a contract. If moving from another state, it is more realistic to conservatively estimate the vacancy period rather than feeling reassured by lower purchase prices and property tax burdens compared to the previous residence.

Augusta overlaps with the South Carolina area across the Savannah River, so many investors compare properties with those in the Aiken area across the river. Given the low purchase prices, many approach this as a cash flow investment, where the cash-on-cash return from monthly income constitutes a larger portion of total returns than capital appreciation. However, since the population growth is not as pronounced as in the Atlanta metro area, it is advisable to check the vacancy trends in the neighborhood to see if rental demand remains steady over the long term. When factoring in the increase in assets due to mortgage principal repayment, total returns will look slightly better than the cash-on-cash return figure.

In markets like Augusta, where the purchase price is low, it is easy to be misled by looking solely at the total yield. To get a clearer picture of actual cash flow, one must also consider the cap rate that accounts for vacancy rates and the cash-on-cash return that takes loan conditions into account.
