If the purchase agreement stated that they would vacate by July 30th, then their failure to do so would be a breach of contract. They could potentially be liable for costs you suffer as a result of their breach. (hotel, food etc.) For a definitive answer and how things should proceed you should sit down with an attorney to review your circumstances in detail and advise you.
