Here is a capture of the listing, which indicates "New this week:" with the new MLS number (878592)
And the old listing (MLS 857584):
From my experience as a former home owner, I recall this was not a legitimate practice. It is done because if a house sits on the market too long, people will not want to look at it because they will just assume there is something wrong with it. But if it is a "new" listing, then people may go and see it.
Here is the listing agent: Jay Weinberg
I'm emailing him for an explanation, stay tuned....
Here is his response:
"Hello Mr Teel,The reason is we didn’t get it relisted before it expired so it goes in as new simple as that."
A convenient excuse, if you ask me. The rest of his email was a pitch for using an agent - but why would I want an agent that does not stay on top of things?
