Caller asks if I want to sell my house, then quickly hangs up.  Caller ID shows Long Realty Co.

Received a call from 520-297-1005.  The woman said she's from Long Realty and wants to know if I want to sell my home.  I asked why would she call me, asking me such a question.  There was no response.  It was as if the line went dead.

Got a call from this number, we answered, there was a long pause, then the other end hung up. Googling the number turns up lots of links, some from Long Realty in Oro Valley, AZ, some from Sun City Vistoso, same place. The web pages all say this is their fax line, but there was no fax tone. Sun City Vistoso site says they are looking for houses to re-sell. Maybe an independent Long Realty affiliated agent; some kind of unsolicited call for sure.
