Whether you are buying or selling your home, be careful when posting personal / private information about your transaction on social media outlets, especially Facebook and Twitter. I can tell you first hand, most buyers and sellers search the internet in hopes of gaining an advantage in their transaction. Social media outlets are an easy place to find information.
Its important to keep in mind, you haven’t sold or bought your house until the transaction has closed. Most real estate contracts have contingencies for financing and inspections, and issues can, and do arise. For that reason, neither party is done negotiating until all contingencies have been met and the deal is closed. So guess what happens when a seller goes on Facebook and announces they sold their home and couldn’t believe the cheapskate they had to deal with? Do you think a buyer would and should remember that comment when they are negotiating the repairs / remedy for the inspection? Or, how about when a buyer announces they are excited about buying a new home, but stressed about moving since they just notified their landlord and have to move out by the end of the month. Even the most subtle comments can be used against you.
There certainly isn’t anything wrong with being excited buying a new home. However, I would strongly urge you and your family to wait quietly until AFTER your transaction has closed before you post anything on Facebook or Twitter.
