Two Nevada County parcels owned by the now-defunct Catlin Properties Inc. will be auctioned off tomorrow after the Sacramento-based company defaulted on its loans.

Catlin owes Guaranty Bank about $9.5 million on the properties, which include the 65-acre SouthHill Village development in Grass Valley and the former Indian Springs Vineyard.

A number of liens were issued against the company in 2009, and Catlin also defaulted on properties in Rancho Cordova and Novato.

Both properties go up for a trustee sale at 12:30 p.m. Friday on the steps of the Nevada County Courthouse at 201 Church St., in downtown Nevada City.
