Wiew FAQ: how the estimates, data and privacy actually work

01How does Wiew come up with an estimate?

Every Wiew estimate starts with the public record: what a property is, how big it is, and when it last changed hands. Wiew reads that record, then looks at recorded sales and public assessments on comparable homes nearby.

From those patterns it returns a value. Not one number, a range. We do not publish the exact recipe, but we do show you what went in and when it was measured. That is the part: you can always see the grain and the date behind a figure.

02What is a modeled band, and why not just one number?

A modeled band is a range Wiew believes the value most likely sits inside: a low end and a high end. It is deliberately not a single dollar figure.

Here is why. No model knows the exact price one buyer will pay for one home on one day. A lone number hides that uncertainty. A band shows it. The width is information too: a narrow band means plenty of similar, recent sales nearby; a wide band means the evidence is thin or old. Reading the width is half the skill.

03How current is the data behind an estimate?

It depends on the input, so Wiew dates each one rather than pretend they all arrived together. Recorded sales show up only after they are filed with public offices, which takes weeks or months. Public assessments move on a slower municipal cycle. Broader market signals shift more often.

An estimate blends those different clocks. Instead of burying that, Wiew stamps a date on the pieces, so you can see whether you are looking at a fresh read or an older one.

04Is my data private when I use Wiew?

Short answer: yes, and it is built into how search works. Wiew is address-first. You look up a place, not a person. Wiew does not run name-to-property searches, so it cannot be used to find where someone lives.

The things that are about you (the homes you save, your borrowing-power profile, your plans) stay tied to your account. Wiew treats them as private, not as a listing to broadcast or a record to sell. Property facts are public; your situation is not, and Wiew keeps that line.

05Where does Wiew work best?

Wiew is deepest in Massachusetts. That is where the property detail, sales history and local context are richest, so bands come back tighter and comparisons are stronger.

It works elsewhere too, but the grain varies by state, because public records vary by state. Some places publish rich and current data; others are thinner or slower to update. Rules and costs differ the same way.

When coverage is thin, the result is a wider band, and Wiew shows it as one. We would rather give you a wide, true range than a narrow, invented number.

06Why won't Wiew just tell me if a house is good or bad?

Because good and bad are not features of a house. They describe a match. The same home can be right for one person and wrong for the next, and no star rating can tell those two people apart.

What actually matters is fit: your money, your plans, your tolerance for risk. A price that stretches one buyer is comfortable for another. A layout that is wrong for a growing family is perfect for a couple who work from home.

A house isn't good or bad. It either fits your money, your plans and your risk, or it doesn't.

So Wiew does not hand out grades. It gives you sourced, dated facts and a read on how a specific place fits you, then lets you make the call.
