Is deed-in lieu of foreclosure right for me, how can I proce

I moved to another state because the opportunites were better, I couldn't sell my house so I rented it. It has been 6 months and my tenant cannot pay the rent. I cannot pay both my rent and mortgage. I just put up my house for sale but I cannot pay this month's payment plus the market in Miami is horrible. At this point I just want to get rid of the problem. I am calling the bank next monday, should I bring up DLF? Is this for me? How long does a DLF stay in my credit history? Would this affect future employment opportunies, should I tell my employeer?
