On top of this if at all possible I’d recommend choosing specific neighborhoods to become an expert on as opposed to just thinking “anywhere in the San Antonio market could work”.

And my #1 issue is I don't see any actions to address this in a meaningful, market specific manner. 

Specifically for us, we focus on the outskirts of Orlando.

You may have to search a bit for the right contractor or engineer - sometimes I see one solution dominating in an area - "that is how we always do it"  Thanks for the input - yes, it sounds like the specific area this house is in is particularly bad for foundation issues.  

If you have specific questions about property management, I'll be happy to help!

Specific topics come in waves.

You point out specifically "... on forum run by his publisher." 

I was specifically interested in his 2nd plan which was "Building wealth through single-family homes" where he basically says you save enough to buy your first property along with enough for other fees and then you just keep saving the money you make from that property along with some money you save from your job and once you have enough money you buy your next property and then you basically just keep repeating that until you have your desired amount of properties.

Specifically, I’d love to hear about best practices for managing shared spaces, screening tenants, and setting up house rules.Additionally, I plan to split the utilities among the tenants—any advice on how to handle this efficiently would be greatly appreciated!

Cities don't play fair when they decide to go after you.One thing I would also suggest you do is look on AirBnB for the specific building you want to buy in.
