Living in South Union

South Union is a transitional Renton neighborhood where a -18.8% YoY price shift has brought the median to $661,000, offering renewed value in a corridor undergoing gradual reinvestment. At $365/sqft and 31 median days on market, the pace is moderate and the pricing presents opportunity for buyers who've been priced out of tighter Renton pockets. The area benefits from proximity to Renton's employment and transit infrastructure.

South Union sits within easy reach of Renton's downtown amenities, including the Renton Transit Center, local parks, and Rainier Avenue dining. The neighborhood has seen incremental investment in recent years and offers a more urban lifestyle than outlying Renton areas. The current price softness makes it a compelling value play for buyers watching the market.
