If you are selling your house you might want to take care about posting anything that might weaken your negotiating power. Avoid posting anything about being in a hurry to sell. Buyers will pick up on anything that sounds desperate and use it to their advantage.
It is best not to answer too many questions or post that the real reason you are selling is because you hate the house and the neighborhood. Keep everything positive.
Home buyers should take care about what they post on Facebook recognizing that the sellers may see it. They will check you out every way they can before accepting your offer.
There are plenty of scams on social media too and it is a great place for the crooks to collect information they can use for fraud.
Posting that your house is on the market with a link to more information about it is usually a good idea. If you are not being represented by a real estate agent you may receive many messages and comments from local agents.
Personally, I don’t crowd-source advice about anything on Facebook. My friends are wonderful but they are rarely the best source of advice about money, home repairs, or health care.
Remember real estate is local. Advice from friends who have bought or sold real estate in other states may not apply to your situation.
Please be careful out there.
