Hi Lisa, Vladimir is correct, the odds of your lender agreeing to a short sale in your situation is slim to none. IF they do by any stretch of the imagination agree to a short sale while your payments are current, they will be in no hurry to complete the process (you cause no current loss to the banks financial position), you may be looking at a very long and drawn out process...You may do better with a loan modification...FYI
But to answer your question, YES your credit will be negatively affected by a short sale.
Good luck to you - Yesterday, 16:57
