Forest Knolls is widely considered a desirable neighborhood, but this three-bed townhome has been searching for a buyer since last September. It's lowered its price from $975,000 to $900,000, but its scary orange carpeting may be scaring potential homeowners away.

This Saint Francis Wood home is on a park-like half-acre lot. However, it's gone unsold since it first listed back in November for $6.85 million, possibly in part because of the blood-red color of the kitchen and touches such as electric blue carpeting. It's now asking $6.5 million.
