The Costly Mistake Files — Volume I of the Home Value Archive

A house does not lose its value all at once. It loses it in decisions that felt smart at the time. The Costly Mistake Files is forty of them, room by room, with what each one cost to build and what a buyer deducts to undo it.

63 pages, 40 mistake files across 5 parts, with schematic diagrams drawn for this edition: why a television over the fireplace ends up nearly seven feet off the floor, what an oversized sectional does to the size a room appears to be, and why an uninsulated garage ceiling makes the bedroom above it the worst room in the house.

Inside: the living room trends buyers price against, the kitchen upgrades that recoup well under half, the backyard projects that cost you twice — pools, spas, courts, turf and the pergola with no permit under it — and the garage nobody planned. Plus what it costs to build against what comes back, and what buyers deduct to undo it.
