While crunching numbers, I often receive inquiries about getting stuck on the property tax section for Hilo listings. Looking at the Hawaii County tax rate table, it can be confusing at first since the categories are divided into several parts. To put it simply, this means that the tax rate differs significantly depending on whether the property is for personal use or for rental.

Hawaii County applies a lower tax rate of $5.75 per $1,000 for owner-occupied properties, while investment properties for rent are taxed at a much higher rate of $11.10 per $1,000 (for properties valued under $2 million). When converted to an effective tax rate, owner-occupied properties are at 0.575%, while rental properties are at 1.11%, nearly double the difference. When calculating rental income in Hilo, this rental tax rate should be the basis.

According to RentCafe, the average rent in Hilo for 2026 is $1,779, and the recent median sale price according to Redfin is $555,000. Calculating the total yield from these numbers gives an annual rental income of $21,348 divided by the purchase price, resulting in a yield of 3.8%. In simpler terms, this means that the rental income accounts for 3.8% of the purchase price without deducting management fees and taxes, but when factoring in the rental property tax rate of 1.11%, the annual property tax alone amounts to $6,161 based on the $555,000 price.

When adding insurance (which is often higher in Hawaii due to volcanic and hurricane-related coverage), maintenance costs, HOA fees, and vacancy losses, operating expenses frequently exceed half of the rental income. The property tax of $6,161 already accounts for 29% of the annual rental income, so when adding insurance and management fees, it's easy to surpass the 50% rule. If we conservatively estimate operating expenses at 55% of rental income, the NOI would be about $9,600, and the cap rate would drop to around 1.7%.

Looking at the rental price trends in Hilo according to RentCafe, they are set at a level 31% lower than the overall average in Hawaii. Unlike tourist-centric Oahu or Maui, Hilo is known for having a higher proportion of long-term tenants, indicating that it may be a market more focused on long-term rental demand rather than short-term rentals.

If we assume a 20% down payment, the actual cash invested for a $555,000 property would be around $111,000 plus closing costs. If the pre-tax cash flow, factoring in loan interest and the previously calculated property tax of $6,161, is $1,500 annually, the cash-on-cash return would only be about 1.4%. In simpler terms, this suggests that Hilo is not a particularly attractive market based solely on pure cash flow, and a total return perspective that includes long-term appreciation or asset growth from loan principal repayment becomes more important.

Even under the 1% rule, 1% of $555,000 is $5,550, but the actual rent of $1,779 is only about one-third of that. The school district often considered by Korean families in Hilo is near Waiakea, but since school district boundaries frequently change, it's advisable to check the assigned school for the specific address before purchasing. If you are coming from another state, be sure to accurately reflect the significant difference in tax rates between owner-occupied and rental properties in your calculations.

In the long run, it's particularly important to assess the market not just from the perspective of rental income but from a total return standpoint. When considering asset growth from loan principal repayment, potential appreciation, and tax benefits from depreciation, there is room for actual investment performance to improve beyond the cap rate of 1.7%. However, risks from natural disasters like volcanic activity or hurricanes can affect not only insurance costs but also property values, so it's wise to carefully review the conditions of insurance coverage.

When reviewing properties, it's best to verify the owner-occupied and rental categories on the tax rate table by address to avoid confusion. Sometimes, the estimated property tax listed by agents or in property descriptions is based on owner-occupied rates, so it's necessary to develop the habit of recalculating based on the actual rental tax rate.
