Security cameras inside a home?

Your instinct is right. Assume the cameras are recording audio and video, and act accordingly. It's legal for homeowners to have security cameras inside their home in most states, though audio recording laws vary by state. Some states require all parties to consent to audio recording, which means the seller technically needs your consent to record your conversations. In practice, most buyers don't push this issue during a showing. The practical approach is to keep your comments neutral while inside the home. Don't discuss your offer strategy, how much you love or hate the house, what you think it's worth, or any weaknesses you've noticed that you'd use in negotiations. Save all of that for after you leave the property. Anything you say inside the home could be relayed to the seller and used against you in negotiations. Walk through, take notes silently if you want, and discuss everything with your agent once you're in the car or back at their office. This isn't paranoia, it's just smart buying.

Depending on your state -- Sellers do not have to let agents or Buyers know if there are cameras inside or outside of the home. One of the first counseling items we tell Buyer clients is hold off chatting about the house until we are back in the car -- especially if they really like it. If the home Seller know the potential Buyer is very enthusiastic about the home -- it could affect their negotiation. Keep a poker face!

With technology advancing you never know if you are being watched or listened to in homes. It is a good idea to wait until you have left the home to discuss it with your Realtor!
