Why are you trying to "get out" of your real estate contract? Do you have to relocate? Are you in a situation where you cannot afford the payments anymore? Did the contract have a two year call meaning you have a balloon payment for the balance coming due? It's hard to say what your options are without more information.
As far as "getting out" of the contract and not "getting sued" I cannot and will not give legal advice. You may need to consult an attorney. If do make sure to contact one that specializes in real estate.
Is the holder of your note the person or persons you bought the home through or did they sell the note? I would suggest you contact the owner of the RE contract. If it's a situation of a two year call on the note explain that you can't get financing and see if they'll extend the term. If it's that you can no longer afford the payments see if you can negotiate new terms. If you do not have a call or balloon payment coming maybe you can sell the house. Is the RE contract assumable? If so can it be assumed with or without the note holder's permission? Maybe you could sell with a new buyer assuming the contract or you could sell on a wrap around contract? Your only option may be to sign the property back to them, again depending on why you want or need out.

The buyer and seller each agreed to specific terms and obligations that must be adhered to. The contract should spell out remedies if either party fails to meet the all of their obligations. Review the contract and hire an attorney so you may understand the possible consequences if you are unable or unwilling to continue meeting the terms of the agreement.
But check with your Realtor, agent or attorney (whomever you used to help you write and submit the contract), and they'll be able to fill you in on your options.
