County-Wide Gross Yield: What the 3.55% Hides

At a $753,837 median home price and $2,232/month median rent, Snohomish County posts a 3.55% gross yield on paper. That single number does less analytical work than it appears to. It blends transit-premium parcels near the new Lynnwood Link stations, affordability-tier land in Marysville and Lake Stevens with higher yield potential, and riverine properties carrying mandatory flood insurance that quietly strips 30–60 basis points from net returns.

The county-wide figure also tells you nothing about the tax load. At an effective rate of roughly 0.81% on assessed value, a property purchased at the $753,837 median carries an annual tax bill of about $6,100. That alone consumes 270 basis points of the 355-basis-point gross yield before debt service, insurance, management, or vacancy. Net cap rates on stabilized single-family rentals in this county are realistically landing in the 1.0%–1.8% range for properties acquired near median price. This is an appreciation market. Investors underwriting for cash flow on day one at these price levels are fighting the structure of the market.

The spread across sub-markets is where the real cap rate analysis lives.

Neighborhood and Sub-Market Breakdown

Bothell and Lynnwood (Southwest Corridor)

These two cities form the county's most competitive investment sub-market. Bothell's King County adjacency and proximity to the tech employment corridor sustains premium pricing and low vacancy, which is useful for exit liquidity but compresses entry yields below the already-thin county average. Lynnwood's Lynnwood City Center and Mountlake Terrace stations, which opened on August 30, 2024 as part of the Lynnwood Link Extension, have added a transit premium to walkable parcels. Renter pools here skew toward Seattle and Bellevue commuters, which supports rent floors but also means landlords compete with high-amenity newer product.

Gross yields in Bothell and Lynnwood are almost certainly below the 3.55% county median for single-family rentals, given above-median pricing and rents that have not risen proportionally. Net cap rates, after the ~$6,100 tax drag on a median-priced asset, are structurally thin. The investment thesis here is not income. It is basis near transit infrastructure and a King County price floor that limits downside.

The ADU angle is more interesting. Ordinance 25-014 (March 2025) now allows duplexes and attached single-family dwellings to carry ADUs in urban zones, and state law effective July 1, 2025 requires at least two ADUs to be permitted on urban single-family lots up to 1,000 sq ft each, with no added parking required. On a Lynnwood or Bothell parcel already at $750K, adding two ADUs at market rent could push blended gross yield toward 5.5%–6.0% if construction costs are managed, converting a thin yield into a workable return.

Everett (County Seat)

Everett presents a cleaner price-band framework for underwriting. The market segments clearly: homes under $750K move with high velocity and hold their seller-market dynamic, the $750K–$949K band clears if pricing is precise, and $950K and above sees slower absorption and more negotiating room.

For investors, the sub-$750K acquisition band in Everett offers a marginally better gross yield entry point than the county median because per-dollar pricing is lower while rents in the Everett market still benefit from the same Boeing and government employer base. The 2024 annual average covered wage of $79,964 county-wide, with manufacturing jobs at $117,339, underpins tenant capacity to pay $2,200+ monthly. Vacancy risk in this band is lower because velocity is highest: homes sell quickly, which is a proxy for renter demand absorption too.

Net cap rates in Everett still face the same ~$5,500–$6,100 tax headwind on median-priced assets. At a $700K acquisition, the tax bill runs roughly $5,670 at a 0.81% effective rate, which consumes about 270 basis points of a hypothetical 3.65%–3.75% gross yield. Net of taxes alone, you are at 0.95%–1.05% before any other operating expense.

Marysville and Lake Stevens (Northern Affordability Tier)

These markets offer the county's best gross yield potential because entry prices sit below the county median and new construction competition sets a rent ceiling that is still supported by a workforce tenant base. First-time buyers and families priced out of Bothell and Lynnwood have been absorbing inventory here.

Lower absolute price with a rent rate that does not decline proportionally to the price discount produces better gross yield math. An investor acquiring at $600K–$650K in this tier, with rents in the $2,000–$2,100 range, is looking at a gross yield closer to 3.85%–4.20%, a 30–65 basis point improvement over the county aggregate. The tax bill at $625K runs about $5,060 annually, consuming roughly 240 basis points. Net cap rates here, while still sub-2% before full expense loading, give investors slightly more room than the transit-premium southwest corridor.

The risk offset is real: Marysville and Lake Stevens carry greater price sensitivity to rate movements. If buyer purchasing power erodes further, these markets see faster price discovery downward than Bothell or Lynnwood. Rising new listing counts in June 2025 without proportional closings confirmed that absorption is being tested.

All net yield estimates are tax-drag only. Full expense loading (management, maintenance, vacancy, insurance) pulls realized cap rates lower.

Flood Insurance: A Non-Trivial Yield Adjuster

Redfin's climate model flags 16,349 Snohomish County properties as severe flood-risk assets, placing the county in the "extreme" designation. FEMA updated Digital Flood Insurance Rate Maps in June 2020, revising Zone AE boundaries along the Skykomish, Sultan, Snoqualmie, and Snohomish rivers.

For riverine acquisitions in particular, National Flood Insurance Program premiums or private flood coverage can run $1,500–$3,000 annually on a $700K–$800K property depending on elevation and zone designation. At $2,000 in flood premium on a $750K asset generating $26,784 gross annual rent, that is another 75 basis points stripped from gross yield before any other expense. Investors underwriting near river corridors without first pulling the post-2020 FIRM panel for the specific parcel are mispricing the deal.

Cap Rate Outlook

The direction of cap rates from here depends on two variables pulling in opposite directions: price and rent.

On price, the market is softening slightly. The median fell from $755,500 in April 2025 to $750,000 in April 2026, a modest compression. Inventory jumped 58% year-over-year by April 2026, giving buyers negotiating power for the first time in years. If this trend continues, acquisition prices drop and gross yields improve for new buyers.

On rent, the $2,232/month ZORI gives no year-over-year change figure in the available data. If rents hold while prices ease modestly, gross yields trend toward 3.65%–3.80% on new acquisitions over the next 12 months, and net cap rates follow proportionally upward.

The bigger medium-term factor is property taxes. The 2025 total levy was $1.851 billion, up 5.96% over 2024, driven by 11 voter-approved measures. The Assessor's 2024 appreciation average of 6.26% feeds directly into 2026 assessed values, meaning investors who close today should stress-test their NOI model against tax bills running 6%–8% higher within 18 months.

ADU buildouts remain the clearest path to yield improvement. Two ADUs on a single-family urban parcel with no parking requirements, enabled by the March 2025 ordinance and July 2025 state law, can move blended yields on a renovated Lynnwood or Everett lot from the low 3% range toward 5%+ on total invested capital. That is where patient investors are finding real return, not in stabilized single-family acquisitions at the current price-to-rent ratio of 28.1x.

The Everett Link Extension's six planned stations and LRC upzoning around Ash Way, Mariner, and SR 99 create land optionality in the 2030s, but the $34.5 billion Sound Transit system deficit introduces real timeline risk. Acquire near those future station areas for the density entitlement, not for a transit premium that may not materialize until the 2040s.
