You can find different strategies on how to find and reach these folks, such as driving for dollars, targeting mailing lists, networking with Realtors and other wholesalers, and having an online presence, plus paid social media ads, etc.

My background involves social work & non-profit management before getting into real estate.

Therefore, we can be manipulated or our judgement can be affected by anything that happened during the day.It's called social engineering and it has multiple variants.

Also, staging and professional photography can help potential buyers visualize the space better.Lastly, think about local advertising—social media, networking, and maybe hosting an event for local agents could help get more eyes on the property.

Obviously, the rules will differ from state to state.The most successful buyers have trusted bidders with cashier’s checks in multiple denominations (for cash sales) and the actual buyers have field runners and people to monitor multiple prospective properties at a given time and check sales status for postponements due to BK, etc.This is the case in larger metro markets where many properties could go to sale but few do so.There are often better ways to acquire properties then auctions.

We used to use them for direct mail, email, and social media ad campaigns. 

I do occasionally post about it on some of the social media sites for travel nurses, such as Travel Nurse Gypsy Housing for example. 

Also, as I love REI I try to focus on that as well and would love to work with some investors in order to share knowledge and learn from each other.Also, I try to provide free content to my followers on my social networks about real estate, but it's everything in Portuguese though... shame :/ Feel free to ask whatever, if I can help, I will.

Look up Devana Came on socials.

Most serious and qualified tenants are searching on the major 3rd party platforms you mentioned + realtor.com, redfin, and a few others.Apartments.com & homes.com are owned by the same company and may offer some additional marketing options.Another strategy to consider here is social media - video marketing.
