Buying a Condo in Seattle: What You Need to Know Before You Sign

Buying a condo in Seattle involves the purchase price plus ongoing costs: HOA dues, property taxes assessed by King County, homeowner's insurance, and closing costs that typically include lender fees, title, and escrow. South Lake Union condos skew toward newer, amenity-rich buildings, which means HOA dues that reflect those amenities. Budget for all of it, not just the down payment.

The purchase price is only the starting line. King County assesses property taxes annually, and your assessed value can shift year to year — check the King County Assessor's database directly for any unit you're seriously considering. HOA dues vary widely by building age, amenities, and reserve fund health. A building with a thin reserve fund is a liability you'll inherit.

Closing costs in Washington State generally run between 2% and 5% of the purchase price, but your lender and escrow company will give you a Loan Estimate that spells out your specific figures. Verify those numbers with your agent and your lender together.

South Lake Union is one of Seattle's most walkable, transit-connected neighborhoods, and its condo inventory reflects that demand. Amazon's campus presence, proximity to Lake Union, and access to the South Lake Union Streetcar make it a consistent draw for tech professionals and urban buyers. Demand here holds up even when broader market conditions soften.

That said, 'good' depends on your situation. SLU high-rises deliver urban density — rooftop decks, concierge services, small floor plans at a premium price per square foot. If you want more space for the dollar, neighborhoods like Capitol Hill or First Hill offer alternatives worth comparing. But if walkability, transit access, and urban energy are your priorities, SLU delivers.

One practical note: research each building individually. Some SLU buildings are FHA-approved; others are not. That affects your financing options and your future buyer pool when you sell.

The process follows these steps: get pre-approved, identify target buildings, review HOA documents, make an offer, complete inspection and due diligence, then close through a title and escrow company. Washington is an escrow state — a neutral escrow officer handles the closing, not an attorney.

The HOA document review is where most buyers underestimate the time and attention required. In Washington State, sellers must provide the Public Offering Statement (for new buildings) or resale certificate, plus meeting minutes, financials, and reserve study. Read them. A reserve fund below the recommended threshold signals potential special assessments ahead.

Since the 2024 NAR settlement, buyer-agency compensation works differently than it did before. Buyers now negotiate compensation with their agent directly, in writing, before touring homes. Understand what you're agreeing to before you sign any representation agreement. Washington Department of Licensing (WA DOL) governs licensed real estate brokers in this state — your agent must be licensed and in good standing.

Prioritize four things: reserve fund health, litigation history, rental cap percentage, and the HOA's financial statements. A building in litigation — whether from construction defects or internal disputes — can freeze your financing and complicate resale.

Check the rental cap. Many Seattle condo buildings limit the percentage of units that can be rented out. If rentals exceed that cap, the building may lose conventional financing eligibility. That's a direct hit to your resale value and your buyer pool down the road.

Ask for the most recent reserve study. Older Seattle buildings — particularly those built during the 1990s condo boom — sometimes carry deferred maintenance that surfaces as special assessments. A current, professionally prepared reserve study tells you where the building stands and what's coming.

South Lake Union falls within Seattle Public Schools (SPS). Families researching schools should verify attendance boundaries directly through SPS, as boundaries shift and open enrollment options vary by year. Washington's Office of Superintendent of Public Instruction (OSPI) publishes school performance data at the state level — that's your most reliable starting point for objective comparisons.

For buyers with school-age children, I recommend cross-referencing OSPI data with the specific SPS school finder tool before making any neighborhood decision. Don't rely on third-party rating sites alone — they aggregate data with lags and methodology that varies.

Conventional loans, FHA loans, and jumbo loans are all available to Seattle condo buyers — but condo financing has building-level requirements that single-family purchases don't. Fannie Mae and Freddie Mac both maintain lists of approved condo projects. FHA has its own approved project list. If your target building isn't on the right list, your loan options narrow fast.

Warrantability matters. A condo building is 'warrantable' when it meets Fannie Mae/Freddie Mac guidelines — things like owner-occupancy ratios, no single entity owning too many units, and no pending litigation. A non-warrantable building forces you into portfolio loans, which typically carry higher rates and stricter terms. Confirm warrantability with your lender before you fall in love with a unit.

Interest rates move with broader economic conditions tracked by sources like FRED (Federal Reserve Economic Data). Get a rate lock strategy in writing from your lender so you're not caught off guard between offer and closing.
