For homeowners to qualify for a short sale, they must fall into any or all of the following circumstances:

• Financial Hardship – There is a situation causing you to have trouble affording your mortgage.
• Monthly Income Shortfall – In other words: “You have more month than money.” A lender will want to see that you cannot afford, or soon will not be able to afford your mortgage.
• Insolvency – The lender will want to see that you do not have significant liquid assets that would allow you to pay down your mortgage.
