Does a mechanic's lien stop a sale?

It clouds title and typically must be paid or released before a clean transfer, so it strongly discourages retail buyers and creates leverage for investors.

What's a notice of commencement?

A document recorded at the start of construction that establishes lien rights for those who work on the project. It is not itself a lien.

Is a mechanic's lien the same as a construction lien?

They are different names for the same concept — a contractor or supplier's claim for unpaid work or materials on a property.

Mechanic's & Construction Liens Explained

A mechanic's lien (also called a construction or materialman's lien) is a claim a contractor, subcontractor, or supplier files when they aren't paid for work or materials on a property. It clouds title and signals an owner who has run short on cash mid-project — a classic distress trigger.

How a mechanic's lien arises

After unpaid work, a contractor records a lien against the improved property, often after a preliminary notice or notice of commencement. The lien attaches to the real estate, not just the owner, so it follows the title until paid or released.

Why it signals distress

An owner facing contractor liens is usually mid-renovation and out of money — a half-finished flip, a stalled build, or a strained landlord. These owners are frequently willing to sell the project to recover what they can.

Finding construction-lien properties

DLRadar captures construction and mechanic's lien exposure (has_construction_lien, has_mechanic_lien) from clerk records and scores it with other distress signals to separate genuine motivation from routine filings.

Releasing or bonding around a lien

Before closing, get a written lien release or payoff from each claimant, and confirm there are no additional subcontractors still inside their filing window. In many states a buyer or owner can 'bond around' a contested mechanic's lien — posting a surety bond that transfers the claim off the title so the sale can proceed while the dispute is litigated. Always order a fresh title search near closing, since a late-filed lien can relate back to the project's commencement date and jump ahead of your position.
