I am in Deal Flow, which is a mentorship/mastermind group led by Cam Cathcart. 

Home needed some work.Lovely group of siblings who were very easy to work with!

There are small communities in Texas where the 3 or 4 small brokerages in town just keep a list between themselves or have created a Facebook group among themselves to promote their listings.I have run across a few Brokers over the years that just worked with buyers in the purchase of HUD/VA foreclosures and were not Realtors and therefore not members of a Board/MLSHowever, in any MLS that I have been involved with if the Broker is a member of the MLS, all of their agents are also required to be members. 

Man I like this group.

In addition, there are Facebook groups for travel nurses where you can post your housing.

By any chance, do you know of any meetups or groups in the southern Tennessee area?

A good way to find deals is by connecting with local real estate agents, wholesalers, or checking out sites like Facebook groups and Craigslist.

Try your local RE groups on Facebook or meetups.

Greenfield is a growing area, and being in a golf course neighborhood across two lots adds a ton of value to your options.I’d recommend starting by connecting with local investor groups or meetups in Indianapolis—Facebook groups or here on BiggerPockets are solid places to find people actively working in that market.

Just my 2 cents, but given the location, I would assume other than a doctor with a young family or a group of 4 friends looking to live downtown.
