Is it possible to sell my house back to the bank.. im current on the payments and it has been on the market for about 4 months. I need help! Is this the same as giving the deed back?

What makes you think the bank wants to buy it? Banks are not in the business of owning real estate.

Do you own less that the martket value? Can you reduce your price?

Need more info to really help here.

It's highly unlikely that the bank wants your property back. They are in business to make money, not own property.

If your concern is that you will default on your mortgage, you should contact the bank and do a "work out". Since they don't want the property, they probably will lower the interest rate (yes, they can and will do that if they believe it is in their best interest) or change the terms of the loan.

They might do a "deed in leu of foreclosure" or "short sale" if that is appropriate. However, they probably will want a valid offer from a qualified buyer using a licensed real estate agent before they will do a "short sale", with you getting no cash out at closing.
There might be tax consequences if you have lived in the house less than 2 of the last 5 years and the house sells for more than what you purchased it for, even if it is a "short sale" or "deed in leu".

Where are you located and why do you wan to give it back to the bank?

The bank does not buy, if after you are several months behind in your payments, they may consider taking the deed back instead of doing a foreclosure but again they may not either.

They may accept a short sale where they take less money than is owed for the property but if you can't sell it for what is owed to the bank, why would the bank want it
