The short answer is no. The short sale will not be affected by owning a mobile home that you are using for a permanent residence. Factors that may affect the short sale would be the amount of liquid savings you have, etc. To ensure all your questions are answered correctly, I suggest contacting a real estate attorney. One that I recommend is Elizabeth Kayser at the Kayser Law firm 512-218-0301 or 866-995-4887 or 727-458-3203.
