620 Darrell Road, Hillsborough has just closed escrow for $5,850,000. The English Country style Hillsborough home for sale offered 5,676 sq. ft. on approx. .54 acre. Just a year and a half ago, this price would be difficult to attain in the Carolands, especially on Darrell Road, which often gets assigned some discount for its close proximity to the freeway. With Hillsborough prices continuing to soar, the five millions price point has become much more mainstream. County records show the tear-down at 620 Darrell Road was purchased in September 2013 for $2,200,000. Judging by the exterior quality, the house was likely completed by the investor for around $2,000,000.
