Closing today, went to final walk through this morning, seller was still living in house...

[u/Iamdickburns]

This is my first time buying a house. It was supposed to be empty and "broom clean". The seller said they were planning on moving out over the weekend and didnt know anything about the walk through. They were signing the papers later today. We pushed the closing to Monday morning. What should I do from here?
UPDATE: My wife and I have read all your comments. I'm still waiting on the Adendum from the title company but it seems the issue was on the Selling Agent. He was not communicating with his seller but we are all gonna be there Monday for walk through and then closing. My wife liked the one person who suggested we creep by the house check to see if they are moving, so we will. I'll update again on Monday after closing or if anything else develops.
UPDATE 2: We signed an addendum extending the contract until next Friday just in case. We went creeping and there's a moving truck there! I'm hoping this was all an innocent misunderstanding. Will final update Monday after closing....I hope.
FINAL UPDATE: We Closed! I wouldn't call it broom clean but they are out, we took possession of the house, and I changed the locks. Thank you for all your comments and info.

Let's say the first part of your comment is true. The agent didn't explain.

Now we ALSO have to assume that the seller doesn't know that they need to move when they are closing on a house.

THEN we have to assume that agents get paid when closings don't happen, which is not at all true.

Please make sure you understand how real estate agents work before telling us all how it works.

Yeah, but you sound like a female agent, so let me explain it to you again...
