Also, let’s say they are late with the rent every month until the lease expires, but they pay.  

This is probably the most up to date information you can get, you can get the data cleaned, formatted and skiptraced for pretty cheap using some new comers like GoliathData. 

One applicant mentioned their desired move-in date in 9 months in the future but that move-in date is way too far from our earliest move-in date (2 months from now). 

When you get the order of possession from the court, it will probably state a date or number of days the tenant has to leave.

You can begin with FSBO leads, expired, your personal circle, and 1 form of paid ads.. this is how I began.Hope this helps, All the best!

Are corporation taxes up to date?

If you are comfortable renting it, then I would avoid the extension and start the refinance process before your maturity date.

In addition, they track vaccination dates.  

Move out time came and they hadn't even started looking for a place etc etc. 2 weeks out from the court date for the eviction they upped and moved and didn't even request the funds (not that I would have given it to them anyways because they were 2 months past the agreed upon move out date).

The federal redemption period is 120 days from the date of sale.
