Okay who held the gun to your head and told you to make an offer. why did you put an offer on this home? You seem to have made a complete blotch of this, you will lose any escrow you have put down on this home if you back out now. Did you you use a Realtor or did you use their Realtor/Listing Agent. If you used theirs you made a bad decision, it is the Seller's agents job to sell the home, they have no loyalty to you what so ever! Didn't you have an Inspection and time to perform this inspection, there was a time there you could have backed out if you found things wrong with the house. You have time to get financing if you said you were financing, so do something to botch your financing, if you can't get financing you can back out as outlined in the contract! But you can not cancel your Financing, It has to be refuse to be given!
