Zestimate, Redfin Estimate, and asking price: interpret the gap
Separate arithmetic from valuation when an asking price differs from an automated estimate.
Quick answer
An asking-price gap is a comparison between two numbers, not proof that either number is correct. Check the estimate's timing, property facts, and available comparable sales, then review condition separately. Use the calculator to expose your assumptions and cash outlay. A local market ratio cannot turn an automated estimate into an individual appraisal.
Understand what the comparison establishes
The CFPB distinguishes a computer-generated valuation model from other valuation approaches. Zillow describes the Zestimate as an estimate rather than an appraisal and explains that available property information affects it. Avoid assuming an AVM never sees condition information or that every difference is a model error.
Write down the source and retrieval date of the estimate you entered. Check the underlying property facts and what you know about recent comparable sales. Do not freeze changing accuracy statistics into a verdict about this home.

Do not count condition twice
The estimate-gap tool keeps your estimate unchanged. It compares asking price and, optionally, asking price plus a repair budget against that estimate. This is cash-outlay arithmetic, not a new appraised value. If an estimate already reflects condition, subtracting the same repairs from it again can repeat the assumption.
Use the market page to examine the selected place, reporting period, and home type. Historical aggregate observations are context; they are not comparable-sale adjustments for the subject property.
- Which facts differ between the listing and the estimate record?
- What condition assumption does your own comparison use?
- Is the market observation the exact location and property type?

Illustrative example
| Comparison | Calculation | Result |
|---|---|---|
| Asking price minus entered estimate | $1,050,000 − $1,000,000 | $50,000 |
| Gap as percent of estimate | $50,000 ÷ $1,000,000 | 5% |
| Asking plus selected repair cash budget | $1,050,000 + $30,000 | $1,080,000 |
| Outlay gap from unchanged estimate | $80,000 ÷ $1,000,000 | 8%; not a corrected AVM |
