Don't miss this deadline or you'll be stuck with the current rent amount.

In college I had a professor who would put deadlines on projects in a very short time window (twenty page paper due in two days).

If I have no deadline, I am useless. 

And if you miss the deadline by one day - you will be taxed and penalized on the entire amount.Look into other possibilities, I think using HELOC would be much safer. 

Don't delay because the deadline for net year may be at hand.

A 1031 has 180 day period which has several deadlines.

I'm assuming this could take some time and become complicated which might make us miss the deadline to file for the overage?

1) You already lost some rent with her, had to evict her, and had to pay to fix the apartment. 2) You gave her a deadline and she missed it. 3) If you are the nice lady who takes your time to track her down and return all her belongings to her at your cost, she isn't going to learn any lesson.

If the owner does not pay the taxes by the deadline we are considering paying the back taxes and taking ownership of the own.
