Most home value tools hide their math. Mine shows it.
The NE Seattle Valuator was built on one idea: if you cannot see where the number comes from, you cannot trust what it tells you to do.
So I built it around King County Assessor records. Every valuation in 98115, 98125, and 98155 traces back to a public parcel, a recorded sale, a documented land and improvement value. No proprietary score. No mystery adjustments. No signal you cannot verify with your own eyes.
Here is what that transparency actually buys you:
Confidence in the baseline. When the tool says your home lands in a range, you can walk the inputs yourself.
Cleaner conversations with your CPA, your attorney, your family. Everyone works from the same public record.
Faster pricing decisions. When you can see the math, you stop debating the model and start debating the strategy.
Fewer surprises at the appraisal stage, because the comps and adjustments were public from the start.
Data refreshes nightly at 2 AM, so what you see today reflects the most recent public information available for your block.
What transparency does not do is replace judgment. Assessor records will not tell you that the kitchen was renovated last winter, or that a corner lot on your block sold for a premium three weeks ago. That is the broker layer. The tool gives you the defensible starting point. The conversation is where the strategy gets built.
Assessor grounded. Nightly refresh. Broker verified.

Then let's talk about the number behind the number.
