Or the sale didn't happen (BK, postponement, etc.)If it went back to the lender there is pretty much no chance to buy it until it they list it.

I guess my fear is ones we gave them a notice, they might postpone and delay the closing process, since they do not have an incentive to do their job fast and find a new tenant. 

But with the birth of my newborn I was trying to postpone that trip.    

We had to postpone their move-in by 2 weeks and told them why.

If this had been a Sheriff Sale the attorney handling the foreclosure would have done the research (had somebody do it) and if could not find the lien holder would have postponed the Sheriff Sale until the next month. 

I plan to call all the escrow offices until I find who is closing and let them know there is a 10k+ issue and hope they will postpone until they can get it all sorted out and by then I should have something filed.

Often, the lender will postpone the foreclosure date if a short sale is in process so it's very possible.

Postponed sales and cancellations tend to throw them off.

Based on what they are paying, I'm guessing they are buy and hold investors that are hoping for some appreciation in the long term.For every successful winning bid there are literlly dozens of hours involved for drive-bys, tracking of postponements and cancellations, due diligence research, etc.

The sale is actually postponed until lifted by court order, not cancelled.
