There is something that people reviewing rental properties for the first time commonly overlook. They often make judgments based solely on the total return rate. If you are looking at your first property in Leonia, you should break down this calculation.

Let's start with the numbers. According to Zillow, the average home value in Leonia is $780,000 (as of 2026). Rental prices vary depending on the type of property. A single-family home rents for about $3,800 per month, while a condo goes for around $2,675. Calculating the total return rate based on single-family homes yields a figure in the 5.8% range. The total return rate is the annual rental income divided by the purchase price, so no costs are factored in.

When you compare single-family homes and condos side by side, the picture changes. Condos have a lower purchase price but come with HOA fees. Single-family homes have a higher purchase price but no HOA fees, meaning you must handle all maintenance yourself. This difference is directly reflected in the cap rate. The cap rate is the annual net operating income divided by the purchase price, and the net operating income is the total income minus property taxes, insurance, HOA fees, maintenance costs, and vacancy losses.

The effective property tax rate in Bergen County is around 1.69% (according to propertytaxrates.org). In areas like Leonia, where home values are high, the tax burden is significant. If you apply the 50% rule and estimate operating costs to be about half of the rental income, the cap rate for single-family homes can drop to the low 2% range. While condos may show a slightly higher cap rate due to their lower purchase price, including HOA fees often reduces that difference.

If you purchased with a mortgage, you also need to look at the cash-on-cash return. This is calculated by dividing the remaining cash flow after paying the loan principal and interest by the down payment and closing costs. Since this is your first property, you might want to keep the down payment percentage low, but that can increase your principal and interest burden, potentially lowering your cash-on-cash return.

For your first rental property, it's safer to shortlist candidates based on total return rates, compare them using cap rates, and then align the loan conditions with cash-on-cash returns. School district boundaries change frequently, so be sure to verify the assigned school for the address before purchasing.

Adding the concept of total income makes the picture even more complete. Total income includes not only the monthly cash flow but also capital gains, asset appreciation from loan principal repayment, and tax benefits from depreciation. In areas like Leonia, where purchase prices consistently rise, even if the cap rate appears low, considering the rate of asset appreciation can change your assessment.

Some people may start their rental investment journey in Leonia while coming from another state. If you carry over the property tax rates from your previous residence, you may encounter errors, so obtaining the actual tax rate and insurance estimates for Bergen County should be your first step with your initial property.

There's another aspect that's easy to overlook when comparing single-family homes and condos within the same budget: the type of tenants. Single-family homes often have families that tend to stay long-term, resulting in shorter vacancy periods, while condos typically have a higher turnover rate among tenants. This difference is reflected in the vacancy loss category, so when calculating net operating income, it's more accurate to apply different vacancy rates for each type rather than using the same rate for both. The more you analyze these details for your first property, the better it will help your investment decisions in the future. Instead of aiming for perfect calculations from the start, a more practical approach is to conservatively estimate vacancy rates and management fees to compare multiple properties on the same basis. In short, your first property is more about developing a habit of consistent verification than achieving perfect numbers. Even if the calculations feel unfamiliar, breaking them down step by step makes it easier than you might think.
