Union City — the southern Alameda County BART-spine city wedged between Hayward and Fremont — is the East Bay's last meaningful price step before the $2M Mission San Jose / Warm Springs wall. The 2026 median sale price sits at $1,361,500, up 0.19% year-over-year (Houzeo Union City), with single-family homes averaging $1,460,900 and condos at $515,000. The Redfin median in early 2026 was $1.3M at $784/sqft (Redfin Union City). Homes pend in around 20 days, receive 4 offers on average, and the market is rated most competitive.
But the citywide $1.36M median masks a wide internal spread. Downtown Union City's median was $1.3M, up 16.5% YoY (Redfin Downtown Union City) — by far the strongest neighborhood growth trajectory. Decoto's average home price sits at $850K (East Bay PMC Union City Guide), Mission Hills and Seven Hills run the upper tier into the $1.6M–$1.9M+ band, and 94587 single-family stock holds the citywide weight.
This is the 2026 sellers' guide for Union City: the Decoto BART corridor, the Mission Hills family tier, the Seven Hills hillside view-home tier, the Alvarado historic core, the Mission Boulevard arterial price band, and the commission math at the $850K–$1.9M Union City price spread — where 5–6% traditional commission still costs sellers $43K–$114K out of equity.

Why Union City Is the East Bay's Last Sub-$1.5M Family Story
Drive south on I-880 from Oakland and the price gradient walks down predictably: Oakland Hills mid-$1M, San Leandro ($900K–$1.1M), Hayward ($1M–$1.2M), Union City ($1.36M average single-family), Fremont ($1.7M+), Mission San Jose ($2M+). Union City is the precise step where southern East Bay buyers can still get a single-family home with BART access without crossing the $1.5M threshold that Fremont's family neighborhoods now sit above. That gap — a $300K–$500K savings vs. comparable Fremont product 5 miles south — is the single biggest reason Union City is still pulling 4 offers per listing and a 20-day median DOM in 2026.
The transit anchor is unique on the East Bay BART spine: Union City BART station (Decoto) is one of the only BART stations south of Hayward where buyers can still close on a single-family home under $1M (entry-tier Decoto product). Add a 38-minute BART ride to downtown SF, a 25-minute drive to Tesla's Fremont plant, a 35-minute drive to Apple Park, and Union City is the East Bay's last meaningful intersection of BART access + sub-$1.5M family-home product.
The buyer pool reflects this: South Bay tech workers priced out of Fremont, Hayward move-up buyers, first-time East Bay buyers leveraging the FHA-eligible Decoto / condo tier, and a deep multigenerational Filipino-American and South Asian community (Union City Wikipedia).
The Union City Neighborhoods That Move the Pricing
Decoto — The $850K BART-Corridor Entry Tier
Decoto is the historic district built around the Union City BART station — older single-family stock from the 1940s–1960s, walkable to BART, and the most consequential commute neighborhood in the city. Average home price runs ~$850,000 (East Bay PMC Union City) — the only sub-$900K single-family corridor in Union City. Sale band: $700K–$1.0M. Buyer pool: BART commuters, first-time East Bay buyers, investors.
Downtown Union City — The $1.3M Growth-Tier Story
The Downtown core has been the strongest-growing neighborhood in the city — $1.3M median, up 16.5% YoY (Redfin Downtown Union City). Mid-century single-family product, walkable to civic services, and the most consistent multi-offer activity in the city. Sale band: $1.0M–$1.6M.
Mission Hills — The $1.3M–$1.6M Family Tier
Mission Hills sits in the eastern hillside zone of Union City, with Mission Hills Middle School as the school anchor and a deep network of cul-de-sac suburban streets. Sale band: $1.3M–$1.6M. Buyer pool: move-up families, James Logan High School priority shoppers, and South Bay tech commuters via 880.
Seven Hills — The Hillside View-Home Premium
Seven Hills runs the upper price tier, well-manicured suburban streets with hillside views toward the bay and Mission Peak. Sale band: $1.4M–$1.9M+. Buyer pool: established families, view-home shoppers, and Mission Peak / Garin Regional Park hike-from-home buyers.
Alvarado — The $1.1M–$1.4M Historic Core
Alvarado is the original Union City (pre-Decoto merger) — older character homes, walkable to historic Union City Boulevard, with newer infill product mixed in. Sale band: $1.1M–$1.4M. Buyer pool: character-home buyers, design-conscious move-up shoppers.
Mission Boulevard Corridor — The Arterial Mid-Tier
Mission Boulevard is the I-880 / 238 corridor strip with quick access to Hayward, Fremont, and the East Bay BART line. Sale band: $1.0M–$1.3M depending on lot and condition. Buyer pool: commuters, investors, and renters-turned-buyers.

Which Union City Listing Path Fits Your Situation?
You have a $700K–$1.0M Decoto BART-corridor home or a Union City condo. Charlie AI at $4,399 is the right tier. At $51,000 in 6% commission on an $850K Decoto home, the math is brutal — Charlie keeps $46,601 of your equity, drives the MLS / disclosure workflow, and a LOQOL CA agent stays the agent of record.
You have a $1.36M Downtown / Alvarado / Mission Boulevard single-family home. Charlie AI at $7,999 vs. $81,690 at 6% commission — $73,691 back in your pocket. With 20-day median DOM and 4 offers per listing, most Union City homes don't need full-service hand-holding. If the home is move-in ready, this is the cleanest tier.
You have a $1.46M Mission Hills family home or Seven Hills view home. White Glove at $22,000–$24,000 still saves $63K–$75K vs. 6% commission, and delivers the staging and managed showings the view-home buyer pool responds to. Professional photography is scheduled and coordinated alongside White Glove, billed separately.
You have a $1.9M Seven Hills upper-tier estate. At $114,000 in 6% commission, you have real budget for full White Glove ($28,000) — paint, staging, in-person showings, and a dedicated human agent (photography scheduled and coordinated alongside, billed separately). You still keep $86K vs. 6%.
