What can I do to gain experience/get a job and get noticed in this field? 

Since Texas is a tax deed state, you gain ownership at auction, but the previous owner has 6 months to 2 years to redeem it by paying your bid plus 25% interest (in year one).

I attended the RALA 3-day training in Phoenix and took a couple of online courses as well, and while I found these courses to be very valuable in helping get a clearer understanding of the space and what it might take to be successful, I eventually I found it most beneficial to bring in a partner/advisor who has built residential assisted living facilities here in Texas and has been running them successfully.

At this point since it's after the fact while not totally correct; you may explore adding the missed asset/basis amount as a selling cost to just reduce your gain. 

Over time, rents may increase, improving your cash flow, and you’ll gain equity and valuable experience managing tenants and property operations.

You don't have to fit into a traditional "avatar" box to bring valuable insight, so don't sell yourself short. :)This is especially true if you rely on furnishedfinder.com as your primary lead source (which you shouldn't, but that's another post) as when you make that connection with a prospective resident, you are selling yourself as a landlord as much as you are the property as a place to live.

I am committed to gaining knowledge and understanding the ins and outs of the industry.

You said you can't sell now, but want to wait for the equity gain.

I’m here to learn as much as I can from this community, connect with like-minded people, and gain insights into smart investing strategies.Looking forward to networking and soaking up knowledge from all of you.

You will gain a lot with this group of investors!
