Nicole a couple of notes, first you can not sell a home without a clear title, no buyer will be able to get a mortgage and cash buyers will not pay retail. Second a loan modification will not get rid of the liens. Lastly with a short sale, it is hard enough with a professional so doing it yourself would be next to impossible. you can hire a listing agent who is well experienced with short sales. the commission is deducted from the banks proceeds, you would be in a better position to be guided by a professional, not pay anymore and have a professional negotiator.
Please see my blog with tips and advice on how to sell your home through a short sale.
