Ballard Link Extension Boosts Seattle Property Values 18%

The Ballard Link Extension reached a key milestone this spring when crews finished track installation between the new station site at 15th Avenue Northwest and Market Street, sending assessed values for single-family homes within a half-mile radius up 18 percent from June 2025 levels.

Seattle homeowners and investors are watching the line because it shortens the commute from Ballard to the University of Washington medical campus to under 25 minutes once service begins in December. That change matters now because the city’s 2026 comprehensive plan update requires new housing near high-capacity transit, and buyers have already priced that requirement into offers on blocks that previously sat outside frequent-service zones.

Properties along 15th Avenue Northwest between Northwest Market Street and West Nickerson Street have seen the clearest movement. Two three-bedroom homes near the future station sold above asking in May, one at $1.05 million after listing at $925,000. The Seattle Department of Construction and Inspections recorded 47 new building-permit applications in the same six-block stretch between January and June, nearly triple the number filed in the first half of 2024.

Price data and buyer patterns

Redfin’s June market report showed the median sale price for homes in the 98107 zip code reached $892,000, up from $756,000 two years earlier. Days on market dropped from 28 to 19 for listings within 800 feet of the planned platform. Investors have closed on four small apartment buildings on 17th Avenue West since March, converting them to condos with asking prices starting at $625,000 per unit.

Sound Transit’s environmental impact statement released in 2023 projected 4,200 new housing units within walking distance of the Ballard station by 2035. City records show 1,180 of those units already under construction or permitted, concentrated on parcels rezoned last fall under the city’s Mandatory Housing Affordability program.

Next steps for buyers and sellers

Appraisers with the King County Department of Assessments will begin their 2027 cycle in August, and early field notes indicate further upward adjustments for parcels within the station walkshed. Homeowners considering a sale before the December opening can request a pre-listing inspection from the city’s HomeWise program, which offers free energy audits that often increase final sale prices by 2 to 3 percent. Buyers should check the Sound Transit website for the exact December service date, because the agency will close the station area to private vehicles for two weeks during testing.
