Why it matters
Hardware is the highest ratio of signal to cost anywhere in a home. It costs almost nothing and it dates a house instantly. Polished brass knobs and hinges say 1990 as loudly as a calendar. Mismatched pulls across one kitchen say the doors were changed and the hardware was reused, or that two people renovated this room a decade apart. That is why it is such a useful tell in a flip. Hardware is the last thing a renovator buys and the first thing they economise on, because a buyer scrolling photos on a phone genuinely does not see it. So when everything else in the room is new and the hinges are still brass, that is a budget speaking, and it tells you to look harder at the things that cost real money and photograph poorly: the panel, the ducts, the roof. For you as a buyer, though, this is good news, and it is worth saying plainly: this is the friendliest item in any Casaroo report. It is cheap, it is fast, it is entirely reversible, and changing the pulls in a kitchen is an afternoon with a screwdriver that makes the room feel years younger. If a house is dated only in its hardware, it is not a dated house. It is a cheap fix wearing a disguise.
How to spot it
Polished brass or gold-tone knobs, hinges and pulls; hinges that do not match the knobs; different pull styles on upper and lower cabinets; towel bars and toilet-roll holders in a finish that matches nothing else in the bathroom; and the giveaway, a brand-new faucet beside brand-old hinges.
What it costs
Handles, knobs and pulls run tens of dollars each at retail, and hinges less. There is no meaningful contractor rate to publish here because most people do it themselves, and that is the honest answer rather than a manufactured range.
What to do
Monitor, and relax about it. Do not let hardware change your offer. Do let it change what you go looking for elsewhere.
Education and triage, not a home inspection. Casaroo names the hardware tier it can see, because it is a reliable clue about the rest of the renovation. It is not, by itself, a problem, and we will never tell you it is.
