I live in florida and I am upside down in my mortgage cannot get refinanced because of my credit can I just walk away and what are the consquences?

You need to contact an attorney that is knowledgeable about loan modifications and workouts. There are many government programs that might provide some relief to your situation, and the way to start the process is to contact your current lender and see what programs they can offer to you. In the event that there are no programs that they can offer, you can try to "short sale" the property and through that process you might be able to negotiate no deficiency in the amounts owed to the lender. If you just walk away, and you do not negotiate a "deed in lieu of foreclosure" with the lender to eliminate any personal liability, the bank will start foreclosure proceedings against you and get a judgment against you personally. They will also be able to sell your property to satisfy their judgment and any deficiency between the amount of proceeds after sale and the amount of their loan (plus attorneys fees, etc.) will be a personal judgment against you that they can pursue against you. Many attorneys  can help you sort through these options. This is specific to Florida law and does not constitute legal advice as the facts presented are anonymous and incomplete.
