Ask them after tomorrow (tax deadline) if he’s comfortable or familiar with your situation.

If you wait to get a court date until they fail to pay by the deadline you could miss the next court date because it is full and your tenant could get an extra month. 

I have a pending buy going on but the other side of the deal is not getting their paperwork done before deadlines.

Get quotes and compare.Account Closed said, demand for contractors is high in Austin and those are the prices that good contractors can get away with, especially for someone who's trying to hit a specific deadline. 

do i just wait for him to miss payment after the notice of 3 day to pay or quit and then begin the eviction process, i feel the only way this will happen is if i block all incoming deposits to my account before the deadline of day 7 so he has NO CHOICE but to contact my realtor to give him a check. however im not sure how legal this is.

Why would a person who is in pre-foreclosure with a deadline quickly approaching not be motivated to sell their house?

He actually meets deadlines, has competitive rates and will loan on as low as 64k.

I haven't done it yet, as we are working on other repairs and upgrades while I sorted out the drama with the previous rental manager, and right down to the wire, getting their deposit itemized and portion returned before my deadline was up.  

Short inspection deadline, large earnest money, and short closing deadlines are always in my contract.

If so, you need to make sure that you have at least 25% paid off before that deadline so that you can get a cash out refi.
