I have a contract to purchase a building. What if the seller refuses to close?
If you have done everything required of you in the sales contract, you can go to court and seek "specific performance" – a judge’s order requiring the seller to transfer the property to you.
As an alternative, you can sue for monetary damages. For example, if the contract has a purchase price of $500,000 and you can show its fair market value is $550,000, the judge may award you the $50,000 difference.
