(Irvine, CA) — Las Vegas ended 2012 in the top 20 for foreclosure rates, despite major improvements.

A year-end survey by RealtyTrac shows one in every 32 Vegas homes had a foreclosure filing last year, down 57% from 2011. Sin City ranked 16th among major metro areas in 2012.

RealtyTrac names the Las Vegas Valley as one of the worst areas to buy a foreclosed home this year. Fewer foreclosures have resulted in tight inventory and relatively small discounts.
