Who called from 2105911837

Nothing but breathing for over a minute.

Called me and left a message of silence.  Then, called my wife and said they had people who wanted our house.

It was creepy, he told me that he had people who wanted to buy my house.  He knew my name, phone number and address.  Who the hell is this person???

Nothing creepy about it.  Tax records are public and on line as are phone numbers

I received a call from this number, which I answered. No one on the other end ever responded. A minute later, my husband received a call from the same number. No message left for us.
Wondering if someone was trying to figure out if we are at home, though they called our cell phones. Or, maybe they were trying to figure out if we were male or female.
