My title company flagged a federal tax lien on the seller that nobody knew about and it saved me from closing on encumbered property

The federal tax lien piece is worth slowing down on, because that $14,000 was a priority lien. The IRS has broad enforcement authority, and a lien filed against the original owner generally attaches to the property itself, which means a buyer who closes with it unsatisfied can find the government's interest surviving the transfer under certain conditions. The exact treatment depends on notice, the nature of the transfer, and whether the IRS was properly notified before close. Have a tax attorney confirm specifics in your jurisdiction if this comes up again, but the core risk you named is real.

The assumption doing the most work in your original deal was that the wholesaler's cheap online search was equivalent to a proper title examination. It was not. County indexes, federal lien registries, and state tax lien filings are separate searches, and automated tools vary widely in which of those they actually query. A proper title exam pulls from the grantor-grantee index, federal judgment and lien databases, and the public record as it actually stands at that county recorder. The cheap search hit none of that for the federal lien.

The risk you did not mention: the ten-day window worked because you had one. On tighter assignment deals where the original purchase agreement has a close date with little float, a late lien discovery can leave you scrambling to extend or forfeit earnest money while the payoff negotiation plays out. The lien being clearable from proceeds was the favorable outcome. Not every lien resolves that cleanly, especially if the original owner disputes the amount or the IRS needs time to issue a payoff figure.

The $1,140 you paid is worth keeping in frame as a reference point for any operator who is still treating title as a formality.

What close timeline did your assignment contract have, and did you have any extension rights built in when that flag came through?

Federal tax liens attach to property, not just to the person, so the $14,000 would have survived your deed.
