When Zillow's Zestimate fits
- A homeowner wants an estimate before talking to anyone: Zillow says it launched the Zestimate for consumers.
- You want to know what number your seller has probably already seen before you sit down.
- You work in one of the 12 states we don't cover yet, such as Texas or Utah.
When Property Scan fits
- Your seller already has an online number, and the night before the listing appointment you want recorded sales, with every adjustment shown, to talk it through.
- You need something to hand the seller: a PDF with your name and brokerage on it, built from recorded sales.
- A rural or acreage home with few sales nearby, where you want to see each comp and swap any comp you disagree with.
Using both
Let the Zestimate be the number your seller starts from, and use a propertyscan.ai report to show the recorded sales and adjustments behind the price you recommend.
