Not found on the market does not mean off-market
A negative listing search is easy to overread. It says no matching listing was found in the checked source at the time of review. It says little by itself about whether an owner would sell.

What the label means
In DirtIQ, a parcel can be shown as 'Not found on the market' when a public-market check has a recorded date and source confidence. Without that support, its status should remain unknown or need a further MLS/HAR check.
The check covers the source and search method used. A listing can appear under another address, be delayed, exist in a licensed system not checked, or change after the review date.
What it does not mean
It does not mean the parcel is available, the owner is motivated, the property has no broker representation, or that unrestricted MLS data can be copied into a packet. A public page and a licensed listing feed also carry different rights.
The safest language keeps the source attached to the observation: 'Not found on the market in the checked public source as of [date].' Avoid describing a parcel as off-market without a separate, appropriate verification.
The next useful check
If market status would change the builder's decision, request a compliant MLS/HAR review or a broker-provided confirmation. Record who checked, when, and whether the result is shareable. Recheck it before relying on the status in a buyer-facing packet.
A missing public listing match is a lead for verification, not evidence of a seller opportunity.
