Many people find the term HOA unfamiliar. Simply put, it refers to the monthly fees that residents share to cover the costs of managing the building and community facilities. When considering new versus existing apartments in Bellevue, it's important to first look at the HOA fees. Newer buildings tend to have more amenities like pools, gyms, and lounges, which also means higher fees.

There are three main factors to consider. First is the rent itself, second is the composition of the management fees, and third is the maintenance risks associated with the building's age. Let's go through them in order.

According to data from 2026, the average rent for an apartment in Bellevue is $2,688. Studios average $2,150, one-bedroom units are $2,492, two-bedroom units are $3,109, and three-bedroom units are $4,235. Additionally, a survey by Kidder Mathews shows that as of the end of 2025, the vacancy rate for buildings with more than 50 units in East King County is 7.1%, while for smaller buildings with fewer than 50 units, it is 5.2%. This indicates that larger new developments tend to have higher vacancy rates, suggesting that recent supply has been concentrated in these areas.

In fact, the total number of units under construction in the Seattle area has decreased by 11% from a year ago, totaling 17,813 units, and new occupancy in the first quarter of 2026 has dropped by 59% from a year ago to just 1,760 units. In East King County, 2,677 units were completed in the last twelve months across ten buildings, with an average of over 260 units per project, which is noteworthy. Larger complexes tend to have more community facilities, leading to higher HOA fees.

To summarize, new constructions have higher management fees but offer the latest insulation and smart home features that can save on heating and cooling costs, along with builder warranties that cover structural and equipment issues. Existing homes may have lower management fees, but if they are over 20 or 30 years old, significant repairs like plumbing or roofing may be on the horizon.

Bellevue is part of King County, where the effective property tax rate is about 0.83%, and the average annual tax is approximately $7,114. Tax rates and assessment methods can vary by county, so families moving from other states should verify this information rather than estimate based on their previous residence.

Bellevue is also a region that has consistently been favored by Korean families due to its school district. While school district ratings can serve as a reference, boundaries change frequently, so it's advisable to confirm the assigned school for the specific address before signing a contract.

If families are considering purchasing rather than renting, they should pay particular attention to the HOA as it is a fixed monthly expense. When adding the mortgage payment to the HOA fees, the actual monthly burden may be higher than initially expected. Conversely, if the management fees include amenities like a pool, gym, and building security, it can reduce personal expenses, so it's wise to review the management fee statement to see what is included.

For families moving to Bellevue from another state, it's also helpful to know that Washington has no state income tax, but property tax and sales tax are relatively high. When budgeting, using the tax structure from their previous residence may not accurately reflect their actual burden, so it's best to compare total monthly expenses based on rent, management fees, and property taxes combined.

To recap the items to check: first, what facilities and services are included in the management fee statement; second, how many years the builder warranty lasts and what it covers; and third, whether the vacancy rate in East King County has increased in the past year. By addressing these three points in order, it becomes much easier to determine which option, new or existing, is more suitable for the current situation.

Investors looking for rental income should note that areas with a concentration of large new developments tend to have higher vacancy rates. When a large number of new units are released at once, there may be room for rent negotiations, but conversely, during periods of reduced supply, the scarcity of existing new units may increase their value, so calculations may vary depending on the timing.
