Ok guys need your help!

Sorry to hear about your situation.
I have always had a great relationship with my dad.
He either stops buy or calls everyday.

If you have been paying the taxes on the property, I assume the bill comes to you every year, just don't pay it next year, and wait until it goes up for a tax sale and buy it.
You would have to wait a year and a day to claim it, but then you would own it.
