Which of the following best describes a "lien" in real estate?

A lien in real estate is best described as a claim against a property for unpaid debts. When a property owner fails to pay certain obligations, such as taxes, mortgage payments, or loans, a lien can be placed on the property. This legal claim provides the creditor with the right to take possession of the property if the debt remains unpaid. It serves as a security interest, ensuring that the lender or holder of the lien can potentially recover their losses through the sale of the property. Liens are crucial in real estate transactions as they can affect ownership rights and marketability, and they must typically be resolved before the property can be sold or refinanced.

The other options do not accurately represent the definition of a lien. Insurance pertains to protecting against risks rather than claims on property. A tenant agreement relates to rental arrangements and does not involve claims for unpaid debts. Lastly, valuation methods focus on determining a property’s worth rather than establishing claims against it.
