Real estate agents are unable to track property online as the information on listing websites was not updated, and buyers could not discover new houses. Subsequently, fewer buyers showed up for open houses, reducing competition for available houses and affecting their prices. Some realtors resorted to manual systems and old-school real estate marketing tactics like cold-calling buyers or passing flyers, while others started sharing property information on social media.

Rapattoni did not confirm if a ransom was paid.
