The location
Union City is in Alameda County, between Fremont and Hayward, with a BART station on the line to San Francisco and Oakland and commuter links across the Dumbarton and other bridges to Silicon Valley. The city is ethnically diverse, with Decoto and Alvarado as older districts, and Union Landing has shopping. Many residents commute to tech employers in Fremont, Newark and San Jose.
The area carries earthquake risk (the Hayward Fault runs through the East Bay), so inspections and insurance matter.
Costs and rules
Foreign nationals can buy freely, with larger down payments of 30-40% from specialist lenders. California property tax is about 1% of purchase price plus local levies, and Proposition 13 limits annual assessed-value increases. FIRPTA withholding of 15% may apply when a foreign owner sells. Read our US buying guide, US mortgage guide and US analysis.
Neighbouring East Bay cities
Fremont and Hayward are adjacent, Castro Valley and San Leandro are north, and Dublin and Pleasanton are inland. See US property for sale.
