Your voicemail doesn’t have to be monotonous or impersonal. What you need is something that is unique to you but works in a professional manner.
Aside from the fact that we can't substantiate a bit of this, of course, the one thing that seems fishy to me is that he's able to not only pick out that she hit him with a Bible (which, depending on his vantage point, I guess he could see - or at least think he sees), but he's able to say which version of the Bible it is. That's awfully odd to me.

Again, “sell to me”, “feel comfortable”. I want their subconscious to hear me say, speaking of which, I found a lot of sellers who reached out to us are just wondering when we're going to try and pull the wool over their eyes or whether the up to something scammy, so I like to just drop in indications that we understand that they're a little nervous about this and the whole transaction is going to be handled by a licensed attorney and a local title company, no kitchen table closings, so everything is being done above board.
