Why is this house (4843 South Pt, Discovery Bay CA 94505 ) valued so low on a per sqft basis?Comparable homes in Discovery Bay, CA are valued in the $200-230 range; this home is at $151. It is only a few years old, but much larger than other homes in the neighborhood. Does the Zillow valuation algorithm reduce the per square foot value if the home is oversized relative to comparables? Is there really an "oversized discount" that we should be aware of as buyers or sellers?
