Base your offer on what genuinely comparable homes recently sold for — not on a percentage of the asking price. The ask is the seller’s opening position, so “five percent under asking” just negotiates against a number the seller invented. Anchor to closed sales, adjust for how long the listing has sat and whether it has already been cut, and decide three numbers before you say anything out loud: where you open, where you’d like to land, and where you walk. That’s the whole discipline. The rest of this post is how to do each piece well.
Why isn’t “X% below asking” a good rule?
Because the asking price isn’t a measurement — it’s a move. Two identical houses on the same street can list $40,000 apart because two sellers had two different moods, two different agents, or two different levels of urgency. Offer “3% under asking” on both and you’ve made two completely different offers while following one rule. A percentage of an invented number is an invented number.
The ask does one job brilliantly: it anchors you. The moment you read it, every number you consider gets measured against it — $475,000 “feels like a deal” on a $500,000 listing whether or not the house is worth $450,000. We’ve written about that anchor and the numbers that orbit it in why an online estimate isn’t a home’s value. The fix isn’t to argue with the anchor. It’s to replace it.
What should you base your offer on instead?
Closed sales. The homes near this one, genuinely similar to it, that finished the negotiation and recorded a price. A closed sale is the one number in this process nobody is still negotiating — the seller wanted more, the buyer wanted less, and the recorded price is where reality landed.
Two cautions make the difference between evidence and noise:
- Sold, not listed. Nearby asking prices copy each other — one optimistic seller resets the street. Closed sales don’t copy; they settle.
- Genuinely comparable. Size, condition, lot, location, age. A bigger, newer house closing higher tells you nothing about this one. Adjust for the differences or drop the comp.
Three to six honest comparables put a floor and ceiling around a home’s value fast. And when they disagree sharply with the ask, you’ve learned the most important thing on the page — the home may be overpriced no matter what the estimate next to it says.
How do days on market and price cuts change your offer?
The comps tell you what the home is worth. The listing’s history tells you how the negotiation will feel. A home that listed this week, priced in line with the comps, gives you little room — the seller has no reason to move yet. The same home ninety days later, still unsold through a price cut, is a different negotiation entirely: the market has been voting no for three months, and the seller has watched it happen.
The comps price the house. The clock prices the seller.
Days on market, the count of price cuts, relistings, and the local sale-to-list ratio — how close to asking homes around here actually close — together tell you whether this market negotiates in inches or in strides. A long-sitting, once-cut listing justifies an opening offer the same house could never support in week one. We’ve unpacked that read in what a stale listing is really telling you.
Should you ever offer over asking?
Yes — when the closed sales support it. In a fast market, the ask can sit below what comparable homes are actually closing for, and “over asking” is just the honest price wearing a dramatic name. The evidence, not the drama, is what makes it fine.
The trap is competing on adrenaline. When five offers land in a weekend, the number that wins is set by the most emotional bidder in the room — and matching them means letting a stranger’s attachment set your price. Decide what the evidence supports, add what the home is genuinely worth to you, and let that be your ceiling. If someone pays more than that, they didn’t beat you. They just paid more than the house was worth to you — which is the one game you can’t lose by leaving.
What three numbers should you set before you offer?
Every negotiation you’ll ever be proud of was decided before it started. Set these three while you’re still calm:
- The opening. Low enough to leave room, defensible enough to be taken seriously — an opening the comps can argue for out loud.
- The target. Where the evidence says this deal should land. Not a hope; a number you could show your most skeptical friend.
- The walk-away. The price where this stops being a good decision — written down, so that crossing it feels like what it is.
The point of deciding early isn’t rigidity. It’s that once you’re attached to the house — and you will be — the pressure of the moment starts making offers on your behalf. Numbers set in advance are the only ones that stay yours.
Where ZETTLD fits
Everything above is work a buyer can do — and almost no buyer does, because the data is scattered and the seller’s side has no reason to hand it over organized. That’s the job we built Buyer’s Intel to do: an independent, buyer-funded read on what a specific home is worth, the comparable sales ranked by how honestly they compare, the listing’s full history, and an opening offer, target, and walk-away number built from that evidence — plus the script for the conversation where you use them.
We’re paid by you and no one else, so the number has no reason to lean toward the sale happening. That’s the entire point. An offer is a test of the price — and you can’t grade a test with the answer key the seller wrote.
