They're often high quality and cost-effective.

Not too shabby for land appreciation.That said, I’d keep an eye on the Elon Effect down southeast.

The lock-in effect of the period from 2016-2022 when interest rates were super low, causing owners with those low rates to not want to sell? 

I have my eyes set on a plot of land near my home where there is high income and significant traffic in a rapidly growing area in Cedar Park, Texas (north of Austin). 

@Phillip Austin I self-manage my properties including some where I do rent by room as a primary strategy, and it is very effective if done well with good screening in place.The difference is starting with shorter leases for me. 

If some other dude wanted to run this business it sounds like they could just buy a mobile home on a similar plot of land for like $200,000 and throw up $40,000 worth of sheds and the like.

Also, check to see if your jurisdiction is practicing "Just Cause Eviction", which went into effect statewide earlier this year for municipalities that which to opt in. 

Yep for one especially in the early stages a hard credit pull would not be useful, just have them do soft checks for the time being and opt out of credit solicitation: www.optoutprescreen.com I could be biased... that said typically working with one lender than can help regardless of where you're looking and having a relationship with that will provide the easiest and most cost effective route long term. 

In your opinion, what is the most effective way to establish an LLC? 

Simplifying to a single operational entity (Series LLC) for rentals and management can effectively meet your goals while minimizing costs.
