When consulting on home purchases in Seattle, many people carefully calculate down payments and mortgage rates, but often overlook property taxes and maintenance costs, treating them as rough estimates. Looking at the actual numbers for King County reveals that the fixed costs are larger than expected.

The effective property tax rate in King County ranges from about 0.85% to 0.92%. Since the overall average in Washington state is around 0.84% to 0.98%, King County maintains a rate that is somewhat lower or similar to the state average. If we consider the median home price in Seattle to be about $860,000, the annual property tax would be approximately $7,700 to $7,800, calculated as $860,000 multiplied by 0.9%. Monthly, this amounts to around $640.

Home insurance premiums can vary significantly depending on how earthquake risk is factored in. Seattle is located near the Cascadia Subduction Zone, so whether or not to purchase earthquake insurance greatly affects the premium. Basic fire and liability insurance typically costs between $1,400 and $1,900 per year, and adding earthquake insurance often adds another $500 to $1,000 annually. If the home is older, it is essential to get an estimate for this.

Maintenance costs are generally estimated at 1% to 1.5% of the home price. For an $860,000 home, it is realistic to set aside about $8,600 to $12,900 annually for maintenance. Seattle has a significant number of homes built between the 1920s and 1960s, leading to more frequent issues with plumbing, electrical systems, and roofing compared to other areas.

When combined, the property tax of about $7,700, insurance of about $1,700, and maintenance costs of around $10,000 result in total annual holding costs of approximately $19,000. When broken down monthly, this amounts to about $1,600, which should be factored into the budget alongside mortgage principal and interest payments.

Compared to nearby areas, Bellevue has higher home prices, which can lead to a similar or slightly lower effective tax rate than Seattle due to the distribution of tax revenue. Pierce County (including Tacoma) generally has a higher effective tax rate than King County. It is worth noting that the choice of county can create differences in annual property taxes for the same budget.

For Korean households, it is helpful to know that Seattle's property taxes are reassessed every January, and if there are objections to the assessed value, a formal appeal can be submitted within the designated timeframe. Especially in recent years, as home prices in Seattle have risen significantly, it is common for assessed values to have increased as well, so checking for any overvaluation compared to actual market prices can lead to practical tax savings.
