My advice: Use an agent who has experience in representing multifamily investors.

Does anyone have any experience with this that can help us?

I have 50+ people on my contracting company only working on the houses I buy and am speaking from that experience starting with zero contractors less than 3 yrs ago and having been burnt very had multiple times throughout the process. 

I’d love to get this group’s thoughts on what to do with 3 acres of undeveloped land (no septic, no water) in the Texas Hill Country that I plan to eventually pass on to my children (read: never sell because it’s family land).

Adding additional assets, a familiar market, buying a house "for free" as I call it, and gaining experience with lower level of risk How did you find this deal and how did you negotiate it?

I sell houses all the time by just listing them on Zillow, so don't think you need to pay a listing agent and if the buyer doesn't drag their realtor into the mix, you might not need to pay a buyers agent either. this is a cautionary tale of the risks of remote rehab with little to no experience looks good in the book but in practice can be very very difficult.. stick close to home.

Has anyone had any experience with Beyond Backgrounds?

I have read books and watched some videos on getting started with rental properties and I want to purchase my first one before the end of 2024 if possible.

As Kate mentioned above there is definitely some marketing efforts needed but once established its about keeping up good reviews and that's all about the guest experience.
