I bought a restaurant and already gave the seller $70,000 deposit 2 month ago. After he got the deposit, the seller wrote a contract, which specifies essential terms such as the deposit, quantity, subject matter, price, but both of us havenít sign yet. After I gave him the deposit, I began to run the restaurant, just a few days ago, he told me that the price he asked is too low, and he wanted to raise the price otherwise he will sell to somebody else, as I know of, he is selling the restaurant by the broker, Another buyer is under agreement with him now. What should I do? Please help!
