The short answer: Your mortgage is only part of owning a home in Honolulu. Zillow’s October 2026 analysis puts the hidden costs of homeownership at $16,566 a year nationally, on top of principal and interest. In Honolulu, the property tax piece is easy to calculate. Insurance and maintenance vary widely by home, so budget for them before you buy.

What homes cost on Oahu right now

October 2026 medians (Honolulu Board of REALTORS): single-family $1,150,000, a median of 15 days on market; condo $499,000, a median of 49 days. The monthly number on a $1,150,000 house and on a $499,000 condo are very different purchases. If you are comparing renting and buying, the worked comparison is in Renting vs. Buying on Oahu.

What Zillow found nationally

Zillow’s October 2026 analysis puts the yearly hidden costs of owning a home at $16,566. That is about $1,380 a month on top of the mortgage. The three buckets are maintenance at $11,171 a year, property taxes at $3,129 a year, and homeowners insurance at $2,266 a year. Those costs have climbed fast. Over the past five years, insurance premiums are up 54 percent, maintenance costs are up 32 percent, and property taxes are up 19 percent. These are national figures. The sections below use Honolulu numbers where they exist and say plainly where they do not.

The Honolulu property tax math

Honolulu property tax is one cost you can calculate exactly, with one important qualification: $3.50 per $1,000 of assessed value is the Residential-class rate for owner-occupied homes. Owner-occupied homes also get a $120,000 homeowner exemption, and the tax applies to the assessed value minus the exemption. Other classes are taxed at higher rates. For the fiscal year running July 1, 2026 to June 30, 2027, the City and County of Honolulu rates are: Residential $3.50; Residential A, first $1M / over $1M $4.00 / $11.40; Bed and Breakfast Home $6.50; Transient Vacation, first $800,000 / over $800,000 $9.00 / $11.50; Hotel and Resort $13.90. A Waikiki condotel taxed at the Transient Vacation or Hotel and Resort rate costs two to four times the Residential rate on the same assessed value. If you are budgeting a condotel, use its class rate, not $3.50. Three examples at the Residential-class rate: Assessed at $600,000: ($600,000 – $120,000) x $3.50 / $1,000 = $1,680 a year, about $140 a month. Assessed at $800,000: ($800,000 – $120,000) x $3.50 / $1,000 = $2,380 a year, about $198 a month. Assessed at $1,000,000: ($1,000,000 – $120,000) x $3.50 / $1,000 = $3,080 a year, about $257 a month. One caution: assessed value is set by the City and County of Honolulu, not by what you paid for the home. Check it before you estimate the tax.

Insurance in Honolulu

Insurance is the fastest rising cost in Zillow’s report, up 54 percent nationally in five years. In Honolulu, hurricane coverage and the age and condition of the roof affect the premium. I do not have a verified Honolulu average for homeowners insurance, so I will not guess at one. Here is the range instead. The Hawaii Department of Commerce and Consumer Affairs publishes sample premiums by insurer, and its December 2025 Oahu samples run from $393 a year to $3,175 a year depending on the insurer and the home. Same island, same kind of policy, very different prices. Get a real quote on the specific home before you finalize your budget. A quote takes a day and removes the biggest unknown in your monthly number. Hawaii insurance is usually a three-policy stack: a base homeowners policy (HO-3, usually with a hurricane exclusion), a separate hurricane policy, and a separate flood policy where the home needs it. The hurricane deductible is the number to watch. Deductibles commonly run 2 percent to 10 percent of the dwelling limit, and Fannie Mae caps the deductible at 5 percent for the loans it buys, so on a $1,000,000 home a 5 percent deductible is $50,000 out of pocket before insurance pays. A cheap policy with a 10 percent deductible can cost you the loan. Condo buyers have one more check: the building’s master policy. Legislative testimony in 2024 cited 375 to 390 Hawaii condo buildings as underinsured for hurricane coverage, and that status can decide whether a unit is financeable. Ask for the master policy summary and the deductible per unit before you offer.

Maintenance on an island

Maintenance is the largest hidden cost nationally at $11,171 a year. Honolulu adds its own factors. Salt air, heavy rain, and year-round warmth wear on roofs, paint, and lanais. Termites are a real cost here too. I do not have a verified Honolulu average for maintenance costs. Use the national figure as a starting point, then adjust for the age and condition of the home: a newer home costs less, an older roof costs more.

Condo fees: the number buyers miss

The monthly fee is part of the purchase price. The median advertised Oahu condo fee was $882 a month in February 2026 (UHERO Hawaii Housing Factbook 2026), and the average from Honolulu Board of REALTORS sales data was $1,051 a month. The Honolulu Board of REALTORS president has put it this way: a $600-a-month fee is roughly the difference between affording a $400,000 condo and a $500,000 one. The fee decides what you can buy. Listings also hide part of the cost in a second line. A unit at 1717 Ala Wai showed a $1,180.75 a month maintenance fee plus a $308.07 a month assessment, for a $1,488.82 total. The assessment is a loan installment for completed capital work, running to 2028. Always add the maintenance fee and the “other fee” together, and ask what the other fee is paying for and when it ends. Insurance can move the fee fast. Ke Kilohana, a Kakaako condo, saw its hurricane premium go from $51,555 in 2023 to $247,824 in 2024, then $148,086 in 2025, alongside a fee increase of more than 50 percent and an assessment of about $300 a month. That is one building, not an island average, but it shows why a buyer should read the last two years of a building’s budget, not just the current fee.

What this means for buyers

Add tax, insurance, maintenance, and the condo fee to the mortgage before you decide what you can afford. Ask for the assessed value, an insurance quote, and the building’s fee and assessment status before you offer. The monthly number that matters is the full number, not just principal and interest.

What this means for sellers

Buyers are doing this math. A home with a newer roof, clean inspection, and clear tax numbers sells easier than one with unknowns. If you are thinking of selling, knowing your numbers first puts you ahead. Condo sellers should have the HOA budget, the current fee, and any assessment status ready before the first showing.
