What is an anchor comp?

The anchor comp is the single closed sale you'd point to first if asked to justify your offer: the recently sold home most similar to the one you're buying in location, size, and condition. Every other comp is used to check and adjust that anchor, not replace it.

How do I find comps on Zillow?

Search the neighborhood, then filter to homes sold in roughly the last 3 to 6 months with similar beds, baths, square footage, and lot size. Favor comps in the same school boundary or micro-neighborhood over ones further away, and set aside any sale that looks distressed, off-market, or otherwise non-representative.

How many comps should I look at?

Three to six recently sold comps is usually enough to see a range and identify one clear anchor. More than that adds noise unless the neighborhood is unusually inconsistent.

Can disclosure findings justify offering above the anchor comp's price?

Yes, if the disclosures and inspection show the home is in meaningfully better condition than the anchor comp, such as a newer roof, updated electrical, or no deferred maintenance where the anchor had some. The adjustment runs both directions.

Finding your offer price: comps, the anchor comp, and disclosures

List price is the seller's opening position, not a valuation. A defensible offer price comes from two separate inputs: what similar homes have actually sold for, and what condition this specific home is actually in. Here's how to combine them into one number.

Step 1: Build a comp set from recently sold homes

On Zillow (or a similar listing site), search the neighborhood and filter to homes sold, not currently listed, within roughly the last 3–6 months. Narrow further by:

Similar beds, baths, and square footage — within about 10–15%
Similar lot size and general style (single story vs. two story, similar age of construction)
Same neighborhood or school attendance boundary, since that alone can move price meaningfully

Set aside anything that looks like an outlier: an estate sale, a flip, an off-market or non-arm's-length transaction, or a listing with unusually long days on market followed by a steep cut. You're looking for ordinary, representative sales.

Step 2: Choose the anchor comp

Out of your comp set, the anchor comp is the one sale you'd point to first if someone asked you to justify your number — the closest match on location, size, and condition, weighted toward whichever sold most recently. If no single comp wins on all three, prioritize in this order:

Recency — markets move; a close match from 8 months ago is weaker evidence than a decent match from 6 weeks ago.
Location — same street or same micro-neighborhood beats a better size match three neighborhoods over.
Condition and size — use this to make small adjustments once recency and location are settled, not to override them.

Step 3: Adjust the anchor using what the disclosures found

The anchor comp's sale price reflects its condition, which you usually don't know precisely, against the subject home's condition, which you now know in detail from the inspection and disclosure documents. That gap is the adjustment.

If the disclosures turned up deferred maintenance the anchor comp likely didn't have (an aging roof, an unscoped sewer lateral, outdated electrical), subtract a reasonable estimate of that cost from the anchor's price, plus a margin if the estimate has a wide range. If the subject home is demonstrably better maintained than the anchor comp, the adjustment can run the other way.

Where the estimate itself comes from

This step only works if you have real cost estimates to plug in, not a gut feeling. A DisclosureDesk report's condition score and stack-ranked cost list are built for exactly this: a defensible number for "how much worse is this home's condition than a typical comp."

Step 4: Layer in current market context

Comps are backward-looking; they tell you what already happened. Check current activity for a forward-looking read:

Rising days on market or recent price cuts on similar active listings suggest there's room below list, and your anchor comp may be pricing in a market that's since softened.
Multiple offers or fast sales on similar homes suggest the opposite — your anchor comp may already be stale-low.

A worked example

Illustrative numbers, not a real property

Anchor comp: a similar home, two streets over, sold 7 weeks ago for $1,250,000, in good condition with a newer roof.

Subject home's disclosures show: original sewer lateral needing replacement (est. $14,000–$18,000) and a roof with roughly 3 years of remaining life (est. $16,000 to replace) — costs the anchor comp likely didn't carry.

Condition adjustment: roughly −$30,000 to −$35,000 off the anchor.

Market check: two similar active listings nearby have each taken one price cut in the last month — a signal to lean toward the lower end of that adjustment range, not the higher end.

DisclosureDesk reads your disclosure packet and returns a condition score and a stack-ranked list of costs, so the adjustment in step 3 is a real number, not a guess.
