LLC, S-LLC, Corporation? Where to start?

[Noah Jenks]

I've bought and flipped 2 houses over the past few years and now I'm moving into rentals. I'm operating primarily out of the Texas foothill region but will be expanding to Kansas City in the next year. I know I need to open an LLC, or something along that vein, but would love any advice on whether to go with an LLC, S-LLC, corporation, S-Corp...something else? Any and all advice is welcome, thank you!
