AUSTIN (Austin Business Journal) — The hottest housing market in the Austin-Round Rock metro area, during this year’s second quarter, is also a target of homebuilders — Elgin.
In the past 12 months, the average sale price for houses in Elgin’s 78621 ZIP code jumped about 57% from $339,590 in the second quarter last year to $532,419 in the second quarter of 2025.
That’s according to The Business Journals’ second-quarter analysis of the country’s hottest housing markets based on quarterly listing and sales data from financial services company Intercontinental Exchange. The rankings aren’t meant to highlight the most expensive or the most popular markets, although some of those are on the list. Instead, rankings spotlight ZIP codes where activity is surging, prices are dramatically rising or homes are selling at a faster pace.
