County-Wide Gross Yield: The Number You Should Not Trust

Pierce County's aggregate gross yield sits at 4.11%, derived from a $1,962 median monthly rent against a $573,349 median home price. That number is accurate at the county level and nearly useless for deal underwriting. It blends Fox Island at $1,200,000 median listing price with Elbe at $389,950, JBLM-adjacent workforce rentals in Lakewood and Spanaway with Tacoma's Hilltop gentrification play, and transit-proximate urban product with rural exurban lots. The 4.11% county-wide figure is a weighted average of radically different sub-markets. The spread across those sub-markets is where investment decisions actually live.

What the aggregate does tell you: Pierce County is a hybrid market. Gross yields below the 5–6% cash-flow threshold mean Day 1 cash flow is not the thesis here. Appreciation driven by King County affordability spillover, JBLM's persistent off-base demand, and population growth is doing more work than rent. Investors who buy at $573,349 expecting immediate positive cash flow from a single unit without value-add are starting with a structural deficit.

Property Tax Drag on Net Yield

Before running sub-market comparisons, account for Washington's property tax. Pierce County's 2025 rates range from $5.05 to $6.70 per $1,000 of assessed value depending on taxing district.

On a representative $573,349 acquisition:

• At $5.05/1,000: annual property tax of about $2,895, or $241/month
• At $6.70/1,000: annual property tax of about $3,841, or $320/month

Against $1,962 gross monthly rent, property tax alone consumes 12–16% of gross rent before any other operating expense. That pulls net operating yield down to roughly 3.4–3.7% before vacancy, management, maintenance, and insurance, assuming the county-level rent figure. Net cap rates in Pierce County on stabilized single-family product are likely printing in the low-to-mid 3% range at median price, occasionally touching 4% in lower-priced submarkets with JBLM tenant profiles.

Washington's 1% statutory cap on annual property tax revenue growth provides a real cost-control advantage. Even as the most recent county-wide revaluation pushed assessed values up about 6%, individual tax bills cannot compound at that same rate over time without voter approval. For a 7–10 year hold, that cap matters for expense underwriting.

Sub-Market Breakdown

JBLM Corridor: Lakewood, University Place, Spanaway

This is Pierce County's most reliable gross-yield pocket. JBLM employs roughly 70% of its service members off-base, creating federally subsidized Basic Allowance for Housing demand concentrated in these submarkets. BAH recipients are effectively pre-qualified tenants with a federal pay guarantor.

Sub-median acquisition prices in Lakewood and Spanaway, both well below the $573,349 county median, improve gross yields relative to the aggregate. A property acquired at $430,000–$470,000 with rents tracking close to the $1,962 county median pushes gross yield to roughly 5.0–5.5%, at or near the cash-flow threshold before expenses.

The 212 new on-base family units under construction at JBLM's Meriwether Landing, with early 2026 delivery targets, represent a modest headwind. New on-base supply incrementally reduces the off-base demand pool. The scale is small relative to the total off-base population, but investors with heavy JBLM tenant concentration should watch on-base housing pipeline.

Tacoma Hilltop

Hilltop operates at a different risk profile. The Hilltop T Line light rail extension opened in September 2023, and the Tacoma Housing Authority's $120 million Housing Hilltop project added more than 230 affordable units in 2024 with backing from Amazon's Housing Equity Fund and Chase Bank.

Market-rate investors face a specific compression dynamic here: transit access and institutional capital are driving land and acquisition prices upward faster than market-rate rents, since affordable units compete directly for the workforce renter pool and suppress achievable market rents. Gross yields on market-rate acquisitions near the Hilltop T Line likely trail the county aggregate as early gentrification pricing gets priced in before rents fully follow. The play is appreciation and density optionality, not current income. Underwrite a longer hold.

Fox Island

At a $1,200,000 median listing price, Fox Island yields are thin by definition. Against $1,962 county median rent, which almost certainly understates achievable rents on a $1.2M property, the implied gross yield is below 2%. Property tax at $6.70/1,000 on a $1.2M assessed value is about $8,040 annually. This is not an income-generating investment at current rents and prices. Fox Island is a primary residence or long-duration appreciation hold.

Elbe and Affordable Exurban Submarkets

At $389,950 median, Elbe and comparable entry-point submarkets produce the county's best gross yields if rent rates are achievable. A $390,000 acquisition at $1,962/month rent implies a gross yield of about 6.0%, the first number in Pierce County that clears the cash-flow threshold before expenses. At a $5.05/1,000 tax rate, property tax runs about $1,969 annually, a fraction of gross rent. The caveat: Pierce Transit's service coverage in exurban submarkets is thin, and a renter pool dependent on car access narrows demand. If the November 2026 ballot measure passes and Pierce Transit expands service 40%, that catchment dynamic improves.

Sub-Market Comparison Table

Yield Compression vs. Decompression

Pierce County's home prices are nearly flat year-over-year, down 0.13% through mid-2026, while the median listing in March 2025 was $558,807, up about 4% from the prior year. Homes averaged 43 days on market in late 2025 versus 34 days the prior year. Prices are decelerating and buyers are gaining negotiating room.

If rents hold at $1,962 while prices drift flat to slightly down, gross yields improve marginally. This is gentle cap rate decompression. The county's 5.2% unemployment rate, above both the Washington state average of 4.8% and the national rate of 4.1%, is the main constraint on rent growth. Softer hiring conditions limit the wage growth that normally pulls rents up. Investors should not model rent growth much above inflation in the near term.

Flood and Insurance Adjustment to Net Yield

Properties near the Nisqually River corridor and Puget Sound shorelines carry a flood insurance exposure that does not show up in FIRM maps alone. Pierce County's flood code extends a 150-foot buffer beyond mapped FEMA AE/VE zones, and a new Nisqually River FEMA flood study, expected to finalize in 2024, is expanding the Special Flood Hazard Area beyond the prior 1996 extent.

Mandatory flood insurance on a federally backed loan for a property mapped into a new AE zone can run $1,500–$3,000 annually for a single-family residence, pulling another 75–150 basis points off net yield on a $400,000–$500,000 acquisition. Run flood zone verification and get insurance quotes before closing on any acquisition near the Nisqually corridor or Puget Sound shoreline. Do not rely on the current FIRM without checking whether the updated study has been adopted in the target area.

ADU Yield Uplift: The Value-Add Case

Washington HB 1337, effective July 23, 2025, allows two ADUs per single-family lot with no owner-occupancy requirement, impact fees capped at 50% of primary-residence fees, and a minimum allowable ADU size of 1,000 square feet. Pierce County is developing a pre-approved ADU design program to reduce permitting friction.

On a $573,349 acquisition generating 4.11% gross yield on the main unit, a second ADU renting at $1,400–$1,600 per month adds roughly 3.0–3.3% in additional gross yield on the original acquisition price. A third unit permitted under HB 1337 pushes the blended gross yield above 7% before expenses on the right property. This is the clearest path to cash-flow positive yields in Pierce County without moving into smaller, exurban submarkets.

Cap Rate Outlook

Pierce County gross yields are likely to drift in a narrow range over the next 12–24 months. Prices are flat; rents face a ceiling from a 5.2% unemployment rate. Real cap rate expansion would require either a price correction or a rent acceleration, and neither is the base case given JBLM's structural demand floor, the King County spillover pool, and a population approaching 942,000.

The two factors with outsized influence on sub-market cap rates are the Sound Transit ST3 decision and the November 2026 Pierce Transit ballot measure. If the Tacoma Dome light rail terminus is cut back to Fife, properties underwritten on a transit premium near planned stations face a direct pricing correction. If Pierce Transit's 40% service expansion passes, suburban and exurban sub-markets gain rental demand from a wider car-free renter pool.

ADU policy is the most actionable lever for investors already in the market or entering at scale. HB 1337 converts a 4.11% gross yield county into a potential 6–7% blended yield market for investors willing to execute value-add construction.
