Buying an Investment Property in the Seattle Area? Here's What You Really Need to Know

If you're thinking about purchasing an investment property in the greater Seattle or Eastside area, there are a few key things you need to consider that go way beyond the usual “location, location, location” advice.

From statewide zoning changes to short-term rental restrictions and fluctuating property taxes, investing in our market requires local insight—and careful planning. Here are the most important factors I walk through with my investor clients when they're evaluating a property’s income potential.

1. Zoning + HB1110: ADU Potential Is a Game-Changer
Thanks to Washington’s House Bill 1110, many properties that were formerly limited to a single-family structure are now eligible for additional units—like a detached ADU or duplex—especially in urban growth areas. That opens the door to house-hacking or adding long-term rental income.

Local Angle: In cities like Kirkland, Redmond, and Issaquah, where land is already scarce, this added flexibility could significantly increase your equity and future rental income. But remember: building costs are high, and permitting processes vary city by city. Know what’s feasible before you factor it into your ROI.

2.Short-Term Rental Restrictions
If you're thinking about Airbnb or VRBO, check the city's stance first. Seattle, for instance, requires licenses and limits most hosts to just one or two properties. Many Eastside cities, like Bellevue and Sammamish, either restrict or heavily regulate short-term rentals—or have HOA rules that ban them outright.

Tip: If short-term rental income is part of your plan, make sure the property is in a jurisdiction that allows it—and that you’re comfortable navigating the licensing process.

3.Property Taxes + Levies
We have a patchwork of school levies, local bonds, and city-by-city assessments here. That means property taxes can vary significantly even within the same zip code. A property with great cash flow on paper might underperform once taxes are factored in.

Where to Look: King County’s tax estimator and your city’s budget documents. And remember—new levies or utility surcharges (hello, stormwater fees) can surprise even seasoned landlords.

4.Tenant Demographics + Rent Demand
In Bellevue, you’re likely attracting tech professionals. In North Bend or Snoqualmie, it might be young families or hybrid commuters. Know who your renter will be before buying—and make sure the property’s layout, condition, and amenities align.

For example: One-bedrooms near Microsoft or Google are gold. In contrast, a 3-bedroom home in a walkable Sammamish neighborhood with good schools might be ideal for longer-term tenants.

5.School Districts Still Matter—Even for Rentals
Whether you plan to rent or sell down the road, school districts like Lake Washington, Bellevue, and Issaquah drive demand. Parents often search rentals by school zone, and that demand typically supports higher rents and lower turnover.

Pro Tip: A home in a top-rated district may cost more upfront, but you’ll likely make it up in stronger appreciation and rental stability.

6.Local Crime + Community Vibe
Some areas are seeing a surge in property crime, especially near light rail stations or high-density developments. Others are investing heavily in neighborhood safety programs. It matters—tenants want to feel safe, and so do you.

Check: Local police blotters, community Facebook groups, and neighborhood associations. I often attend city council meetings so I can keep my clients informed about what’s changing.

7.Vacancy Rates + Renter Competition
The rental market in Seattle and the Eastside has cooled slightly compared to 2021, but demand remains strong for well-located properties. Pay attention to how long units are sitting vacant in the neighborhood you’re considering.

Hint: Tools like Rentometer or even Craigslist can give you a snapshot, but I can also pull local comps and provide a realistic rent estimate for any property you're considering.

8. Job Centers + Commute Time
Our market is driven by major employers like Amazon, Microsoft, Google, and Boeing. Proximity to these job centers—either via road or transit—can dramatically impact your vacancy rate and rent ceiling.

Example: Light rail access has boosted rental demand in areas like Shoreline and North Seattle. On the Eastside, quick I-90 access boosts the appeal of Snoqualmie and North Bend for hybrid workers.

9. HOA Rules + Condo Boards
Thinking of buying a condo or townhome to rent out? Always review the HOA docs. Some buildings restrict the number of rentals allowed, limit lease lengths, or require owner occupancy.

Local Example: Several Bellevue condo associations have recently implemented stricter rental caps post-pandemic. You don’t want to buy assuming you can rent, only to find yourself blocked by bylaws.

10. Environmental Risks + Insurance Costs
From hillside erosion in Issaquah to flood zones along Lake Sammamish, environmental factors can hit your insurance premiums hard. Be sure to pull a preliminary title report and work with a local insurance broker who understands our terrain.

Also: If you're buying a home built before 1980, check whether any retrofitting is required to meet seismic standards.
