Since you missed the deadline for doing so, I think you need to return the October rent to her.You have some preparation to do before you go to court.

If the appraiser does not meet the deadline, they don't get any more assignments.

Many even have wording to the effect that the existence of the alterations on the document has no change in the terms that were originally written there.The contract addendum might allow for inspections, with very short deadlines.

IF I get a hard money loan to get me & my wife started into the rental business and it's time to refinance to get a lower interest rate and pay off the hard money loan before the deadline.

The reo seller did not abide by any deadlines set forth in the purchase agreement and it went on for months before they could close so I backed out.  

I typically have a conversation with the buyer's agent at the preapproval stage where I explain to them that to make this deal work, they are going to have one week (deadline varies with normal closing time in your area, so maybe 3 weeks is reasonable in Indiana) from when we go into contract to find a tenant, get a lease signed specifying $X,000/mo in rent, security deposit made, with a move in date specified on the lease to be 2-4 weeks after our scheduled close of escrow, and the understanding that they can market the rental property to deliver this, in that timeframe, is the only way their buyer is getting legitimately preapproved for a $X50,000 purchase.

If they live there month to month, be aware of the dead line for notices.

If you are generous, you might provide a small carrot if they meet the move-out deadline. 7) If they are less than capable, I would hire a moving company and even rent a storage unit and hotel room if needed but the attorney is probably the way this would go.8) If they are capable but uncooperative for whatever reason, I might offer something up to half of my attorney budget to move.

They are not willing to lower price or extend the closing deadline. 

In a tax foreclosure, the auction has already happens and there is no specific deadline for the case.
