I recently confirmed that the situation can vary greatly depending on the neighborhood in Providence, as illustrated by a calculation mistake made by a landlord I met. He rushed to sign a contract after seeing a property with a high cap rate, assuming that the cash flow would be equally high, but the actual amount deposited into his account each month was far from that figure.

The median rent across Providence is around $2,195 per month (as of May 2026). The property he looked at was in a neighborhood that was slightly above this median, and the purchase price was close to the average home value in Providence, which is $429,449 (Zillow, as of April 30, 2026). The total return calculated by dividing the annual rental income by the purchase price was about 6.1 percent, which is not a bad figure compared to other areas in Rhode Island.

To calculate the cap rate, you first need to subtract operating expenses. The average effective property tax rate in Rhode Island is around 1.32 percent (as of 2026), which is higher than the national average. For a home priced in the $430,000 range, the annual property tax alone would be nearly $5,700, and when you add insurance, maintenance costs, and vacancy losses, the net operating income decreases significantly. Using the 50 percent rule as a rough estimate, the cap rate could drop to around 3 percent. This is nearly half the total return of 6.1 percent he initially saw.

The problem arises next. This landlord mistakenly assumed that the 3 percent cap rate was the same as the cash-on-cash return and proceeded with the contract without reviewing the loan terms. Cash-on-cash return should be calculated based on the actual cash invested, which includes the down payment and closing costs, divided by the pre-tax cash flow. During periods of high interest rates, the principal and interest payments can be substantial, often resulting in a cash-on-cash return that is lower than the cap rate. If you compare neighborhoods within Providence where property tax rates vary slightly, this difference becomes even more pronounced.

Even after distinguishing between cap rate and cash-on-cash return, there are still important factors to consider. This includes the increase in asset value due to loan principal repayment, potential future appreciation, and tax benefits from depreciation, which contribute to the overall return. A lower cash-on-cash return compared to the cap rate does not necessarily mean that the property is a bad choice; it is essential to weigh the speed at which the loan principal accumulates against the potential for appreciation in specific neighborhoods in Providence for a complete assessment.

Among the cases I reviewed, there were instances within Providence where neighborhoods like the East Side and South Providence had significantly different rental levels and property tax assessments. If you have the same budget, it is particularly important in Providence to compare which neighborhoods are more favorable in terms of cap rate and which ones have greater potential for appreciation due to school districts.

Assuming a 20 percent down payment and an actual investment of around $90,000, recalculating the cash-on-cash return could yield results in the 2 percent range, which is lower than the 3 percent cap rate. If this difference had been identified in advance, the landlord could have taken the time to compare loan terms before rushing into the contract. The differences in property tax assessments by neighborhood, as well as the varying rates of rent increases, should also be considered when recalculating cash-on-cash return. This landlord's experience clearly illustrates the importance of not rushing to judgment based solely on the cap rate figure.

From the cases I reviewed, in cities like Providence where there are disparities in property taxes and rental levels by neighborhood, it is particularly important to develop the habit of sequentially examining total return, cap rate, and cash-on-cash return. Many Korean families pay close attention to specific neighborhoods for school district reasons, but school district boundaries change frequently, so I recommend checking the assigned school for the address along with GreatSchools ratings. Property tax and rental regulations can vary by town, so it is advisable to review the detailed terms with a professional before finalizing any contracts.
