That extra lot size is the reason people buy in Montgomery Place over a comparable house on a standard city lot, and public assessment data does not weight it the way an in-person walk-through does. Two houses with identical square footage can carry meaningfully different values once the lot itself is accounted for.
Age of the house works the other direction. A character home from that original build era usually needs a documented list of updates to support top-of-range pricing, since a buyer's home inspection will surface original mechanical systems fast.
Lot size adds value only when a valuation actually accounts for it. Get your hand-reviewed valuation from Joel Dyck.
