Legal Question in Real Estate Law in Michigan

If the seller signed the purchase agreement that you presented, then you have a deal, and it's binding on the seller. If you signed an offer and that offer was never accepted, then you have nothing but the opportunity to make another offer on the property.

Sellers are not obligated to sell to anyone at any price, unless and until they sign a purchase agreement accepting a buyer's offer. Sellers may owe a broker commission if the broker brings a full price and terms offer, and the seller refuses to accept, and close the transaction.

If you hired an attorney, 9 months ago, and his position was that the seller was obligated to proceed with the sale, why didn't he file an action for specific performance?

I suspect that either the seller's acceptance did not mirror the buyer's offer, or there was a contingency, such as a condition precedent to the formation of a contract that was not met.

If in fact, you had a "meeting of the minds" and a fully executed purchase agreement contract, it is not too late to force the seller to comply with the terms of the contract. A real estate attorney can apply the law to the facts of your case with more specific information and a review of the relevant documents.
