A short sale occurs when a homeowner sells their property for less than the amount owed on the mortgage, often due to financial hardship, and requires lender approval to proceed. The short sale process involves negotiations with the lender and may involve complex issues such as multiple liens on the property and the seller's financial qualifications. Effective handling of a short sale requires a knowledgeable real estate professional who understands the associated legal and financial implications, as well as the necessary documentation and pricing strategies.
