Holds
Zillow broadly agrees with the readable independent data.
An unbiased second opinion — with receipts.
We check your Zestimate against the field — Redfin, Homes.com, Realtor.com — and against ClearComp™, a municipality-clean comp value you won't find anywhere else. Then we tell you plainly: it holds, it runs high, or it runs low. No account, no email, nothing collected.
Built from a real investigation that uncovered a $220,000 Zestimate error on a single home — confirmed by Zillow support. See examples from real audits.
n. a small tool that tells you whether something is true.
v. to give someone the real, unspun number — to level with them.
"Zillow said one thing — but I'm gonna level with you."
"To get top dollar, you need a valuation that's on the level."
What the Free Audit Can Find
The free audit makes one of five plain-English calls on your Zestimate, then shows which evidence supported it.
Zillow broadly agrees with the readable independent data.
There are clues, but not enough directional evidence to make a strong call.
Some evidence points toward Zillow running low, but the chain is not complete.
Multiple signals suggest stale or suppressed data may be reinforcing itself.
Independent sources suggest Zillow may be running high instead of low.
These are not diagnosis categories. They are the inputs we use to decide whether the Zestimate holds, needs more evidence, reads low, is stuck low, or reads high.
The premium audit
Every premium audit reads your home against comparable sales, public AVMs, county records, and your Zestimate history — then names what it finds. Two of its tools, ClearComp™ and the CEDC, are Level's own. You won't find them anywhere else:
Premium term
Estimates lean on comparable sales — and some of those sales come from other towns with different markets. ClearComp™ shows your estimate with and without the out-of-town sales, so you can see exactly what they're doing to your number.
Premium term
Compounded Exponential Discrepancy Chain. Small data problems can stack — a wrong fact lowers the estimate, the low estimate anchors the next sale, the low sale drags the history. CEDC checks whether that chain is forming at your address.
Here are two examples.
Suburban Northern New Jersey example
Same-municipality comps came in well above the full comp pool, the neighbor gap was large, and the last sale price was anchoring the estimate low. The audit-supported value landed far above the Zestimate.
Border-town example
ClearComp found some cross-municipality comp drag, but the public AVM stack stayed close to Zillow. With full context, the Zestimate held up here — it reads true.
Zillow, in their own words
"The Zestimate relies heavily on recent transaction data. When a home sells, the algorithm anchors to that final sale price. If that sale price was indeed suppressed — whether by an older Zestimate, a lack of historical data, or other factors — the current Zestimate will reflect and reinforce that price point. It is a feedback loop."
— Zillow Support Agent, May 2026
We need the address to pull public records. You provide your Zestimate because Zillow won't let anyone check it automatically — not even us.
Feedback loops where low estimates cause low sales. Data errors where Zillow has the wrong facts about your home. Algorithm drops from model updates you were never told about. Cross-platform divergences that reveal when only Zillow sees a problem.
We tell you whether your Zestimate holds, reads low, or reads high. If it's off, you get a personalized playbook of exactly what to fix, where to fix it, and how much it typically moves the needle. That's how you level with the number.
Free. No account. No email. Just the truth about your Zestimate.
About
One website's estimate has quietly become the reference price for the American home. Buyers quote it, neighbors quote it, sellers negotiate against it — but the way it's calculated isn't visible, and when it's wrong, the people it affects have very little to push back with.
We built Level after seeing up close what a wrong number can cost someone. The idea is simple: give homeowners real context — independent estimates, public records, and ClearComp™, a comparable-sales value built only from your own municipality — so that when someone says "Zillow says…", you have something concrete to answer with.
We hope you find it useful. If you have comments or suggestions, we'd like to hear them — the form below reaches us.

CEDC Check — Compounded Exponential Discrepancy Chain
Small data problems can stack: a wrong fact lowers the estimate, the low estimate anchors the next sale price, and the low sale drags the estimate history down with it. CEDC checks whether that kind of chain is forming at your address. The score reflects how many links are present and how strongly they connect.
ClearComp™ Report
ClearComp™ takes the comparable sales used to estimate your home and removes the ones outside your municipality. If the estimate changes meaningfully without them, sales from other towns were moving your number. Every sale we used is in the table below.
Built from individual comparable sales, keeping only homes in your municipality.
of the comparable sales behind this estimate come from outside (). Correcting for same-municipality comps only, ClearComp™ puts the value at . A concrete, same-town number you can put next to any Zestimate.
The comp source returned no usable sales for this address, so the comparable-sales analysis could not run. The rest of the audit does not depend on it.
Built from same-municipality comps only.
| Address | City | Price | Dist. | Age | Match | |
|---|---|---|---|---|---|---|
Zillow doesn't publish which comparable sales drive a Zestimate — and comp pools routinely pull from neighboring municipalities; even our own comp source's pool did here. This table shows every sale behind ours — where it is, how recent it is, and how closely it matches your home — so you can judge the evidence yourself.

Summary
What you can do
These are the moves that can change what Zillow shows for your home. Some are confirmed by Zillow itself; others work on records and inputs Zillow says it reads. Each one was selected because of something this audit found at your address, and each carries a grade for the strength of the evidence behind it.
How to read the grades
Things that don't move the number
These circulate constantly as Zestimate advice. The evidence says they don't work — skip them and put the effort into the moves above.
The Zestimate is an estimate, not an appraisal. Nothing in this report is legal or financial advice.
A few details unlock extra diagnostic signals. Add any of them and re-run — still free.
