Tenant debt and about to sell property

Hi everyone, so selling a quad in Louisiana and set to close on Jan 4th, however, I have 3 tenants that have been behind and despite months of asking my manager to process evictions if they did not catch up, I now have over $2K in tenant balances (with $595 & $575 rents by the way), which will likely be around $3K with Dec rents and by the time I sell.  1 of the tenants has a lease with current manager that started around Aug...other 2 had leases with previous managers and are now effectively on month-to-month and being managed by current manager who "will not file eviction in order to avoid losing sale".  Any ideas on possible/feasible recourse against tenants either before or after the sale?  Thank you, Payman
