Seller is trying to back out....Need help!

[Carrie Angyal]

We signed a contract with the seller's on 1/7/18 for a three family house.  Since then we've had the inspection and have been trying to agree on a final contract but have been getting the run around from the seller's realtor.  We have caught out the seller's realtor lying in many situations.  Apparently the two seller's are exes and there is a lot of tension between them and they can't agree to anything.  There are a number of items that need repair including major fire code violations.  We have done everything on our part, financing has been lined up for weeks but they just keep delaying and delaying.  Our closing date on the initial contract is 2/23.   Finally last Friday the seller's realtor said they want to terminate the contract because they can't come to an agreement.  He also mentioned that the boyfriend of one of the sellers now wants the house and they've discussed putting a tenant into the vacant unit so it sounds like they're trying to delay the transaction so the contract will run out.   We're out the inspection fee but furthermore, we want this house.  We're waiting to talk to our attorney tomorrow but does anyone have any advice?
