In this video, you'll learn about tax liens. A tax lien is a claim the government makes on a property when the owner fails to pay the property taxes. When a lien is issued, a tax lien certificate is created by the municipality that reflects the amount owed on the property, plus any interest or penalties due. Investors can purchase property tax liens from a municipality, allowing them to become the new lien owner and collect payments with interest from the property owner.
