We forward a lot of the text communication from agents back to the client, so if it's said in a way that it's possible to figure out, then it can be figured out. For most seller agents, if they will send you that one text that says there's other offers, and that's a lie, and they don't respond to other inquiries about it... is there a way to tell that this is a lie? I'm not sure this is possible even for the best buyer agent
