Otherwise, I would only look for expired listings.

If the tenants are on a term lease VS month to month you can always ask but you have no legal recourse unless they not paying their rent, damaging the property, doing something illegal, endangering others etc...If they are on month to month or the lease has otherwise expired you can give them proper notice (depends on your state what that is, generally 30/60 days) that you are not going to renew their lease. 

The tenant had not been paying rent for the previous few months and the lease expired may 31st and a 30 day non-renewal notice was provided by the previous owner before the ownership change. 

The AppealPeriod expired on October 10, 2020 with no objections so the sale can proceed.What do you guys think ?

And if the seller fails to do so, sellers right to terminate will expire after 7 days.

Reasons for eviction:   habitual late payment, non payment, lease expiration.

My suspicion is that Congress won't pass such legislation, so the moratorium will expire on July 31.Some states (like California) have extended their moratorium further.

That program now has an expiration date of Dec. 31st, 2022.

Since they are set to expire, is it too late to get involved?

Either way with all the redemption rights expired she/you can do whatever with the property that does not require title insurance.
