Land contract, failure to notify

I done a land contract with a real estate agent and I have a huge Problem. we purchased the house and all payments are made. We have made substantial updates on the property. Now that were ready to finance I found out that this property is not able to have a loan because the city I live in will be buying the house to put in a freeway off ramp. I called the DOT and he assured me that this property will be purchased by the state by June 2011 which is when I am supposed to be re financed by. What am I supposed to do? I have filed a report with the Association of Realtor s but they cant give ( legal ) advice. I cant afford the huge retainer a lawyer wants. She NEVER mentioned that the house was gonna be UN fanciable, is that failure to notify. or breach of contract. I have kids and im scared and don't know what to do. please help me. I really need help
