My returns also got a bit too complicated with niche REI stuff for the great tax guy I used for many years and still does my parents and sisters taxes.They handle other REI guys and attend some REIA groups I went to and knew about bonus depreciation, K1, cost segs, schedule E and HELOC junk used for investing and private lending.

Also, I will start attending the Orlando CFRI meetings.  

Direct mailers, calling expired/cancelled listings, attending landlord/investor meetups, cold outreach, social media groups, fsbo platforms.

I've just attended an ACRE summit and meet a couple seasoned investors.

Attend networking events organized by local brokerages and real estate businesses, as well as real estate conferences and workshops.

Hi @Ryan Dunn - the easiest is just to ask a few brokers that are active in the area, you can also simply attend a local real estate investors meetup (a lot of them are free or very inexpensive) and let folks know you're looking to offload your inventory. 

I attend multiple different meetups from Santa Barbara down to Thousand Oaks and sometime LA area :)

And no I'm not able to drive an hour and half to a local rei meeting, unfortunately I can't even attend the new ones that held a town away because I have 2 young children and I can't go that far away from them for that amount of time.  

Do this by attending RE events and joining a local investors association.

You can meet local investors by registering to attend real estate events in your area: https://www.biggerpockets.com/forums/521-events-and-happenings6.
