If you are in any type of a hurry I would stay away from short sales.
There are many factors in a short sale which determine how quickly the lenders make a decision.
*Has the seller provided all the requested documents to the Lender
*Does the seller have a legitimate hardship
*Is the property vacant
*Is the property owner occupied or an an investment home
* Who are the lenders
*What is the market value of the home
*Does the offer reflect market value
*How much is owned on each loan
*Who are the lenders
* Has the loan been sold
*Is the listing agent experienced
*Is it qualified for HAFA
So you see each house and each short sale will have a different combination of answers to the above and that will determine the response. With two loans if they are different lenders then expect 4 or more months.
