I'd try investor focused local facebook groups and ask there. 

There're many groups that hosts can plug into...free Facebook groups and meetups.

I would also have your realtor list the house on Facebook marketplace.

Another option that's worked well for me are Facebook groups.

Check out Facebook groups!

There are plenty of Facebook groups with local hosts, I would try there. 

One individual needs to make the final decisions.Dispute Resolution: Define and agree on a method for resolving disputes that may arise, such as mediation or arbitration, to avoid litigation.Change in Marital Status: What happens to the ownership if a party gets married or divorced?

Atlanta and Houston are my targets.what is the status of the Atlanta tax deed auction now?

I would say try Facebook market local groups and other mid term rentals for people who are looking to stay for 3 to 6 months due to insurance claims.

I don't know much about a community but if you have a facebook there is an ulster county investors page which is semi active.
