A retiree who recently sought advice mentioned wanting to reduce their electricity bill. Initially, it was thought to be due to heavy air conditioning use, but upon inspecting the home, it turned out there was no air conditioning at all. The real issue lay elsewhere. Hawaii's electricity rates are among the highest in the nation, ranging from 42 to 52 cents per kilowatt-hour. Based on the average household usage of 510 kilowatt-hours, the average monthly bill reaches $219. In this area, electricity rates are high due to a power generation structure that relies on imported fuel, regardless of air conditioning usage.

When deciding whether to maintain a single-family home or move to a condo, factors other than electricity costs play a more significant role. The maintenance fees for condos in Oahu, also referred to as AOAO fees, have a median of $526 per month, with some recent cases rising to $882. Recent surveys indicate that condo maintenance fees range from $500 to $1,200 per month. This factor offsets the illusion of lower condo purchase prices.

Looking at actual sale prices, the median price for single-family homes is around $1.1 million, while the median price for condos is approximately $529,000 (as of January 2026). The advantage of single-family homes is the larger space and yard, but there is the burden of handling roof or plumbing repairs on one's own, as there are no additional maintenance fees. Condos have a lighter purchase price, but the monthly maintenance fees can become a larger fixed cost than electricity bills.

Property taxes are relatively favorable. Honolulu's effective tax rate is 0.28%, which is on the lower side, and for a home valued at $873,000, the annual property tax is about $2,482. Seniors aged 65 and older are eligible for a home exemption known as the Kupuna Exemption, which provides deductions based on age: $90,000 for those aged 65-69 and $105,000 for those aged 70-74. Additionally, there is a further deduction of 20% of the property value, capped at $100,000.

Active senior communities, which require residents to be 55 or older, are also worth considering in Oahu. However, new 55+ communities are relatively rare compared to the mainland, so it is essential to carefully compare the maintenance fee structures and facility levels as listings become available.

If moving from the mainland to Oahu, one should not base their decision solely on the lower property tax rate. Home insurance premiums are often higher due to risks from hurricanes and volcanoes, and condos require additional HO-6 insurance to cover personal areas, separate from the building's overall insurance. If considering neighborhoods with good school districts, it is advisable to check the school ratings as well, and for investment properties aiming for rental income, it is crucial to verify that tourism regulations and short-term rental ordinances vary by area.

It is also worth noting that heating and cooling costs are not overly burdensome. Oahu has a relatively stable temperature year-round, and many households manage without air conditioning, with no heating costs incurred. However, the high electricity rates mean that even lighting and appliance usage can lead to bills significantly higher than the mainland average. For single-family homes with solar panels, electricity costs can be substantially reduced, but installing individual panels in condos is practically impossible, which should be considered when comparing the two types. The initial installation costs can be daunting, so it is wise to estimate actual savings and payback periods beforehand.

Ultimately, this retiree found themselves weighing the increased maintenance fees of moving to a condo against the repair costs of maintaining a single-family home. Which option is more advantageous depends on individual circumstances, so it is advisable to break down and compare fixed costs by category each month.
