I would have to own the new investments outright in SC if I stick to single family rentals.

So, generally speaking husband/wife-owned LLC in a non-Community property state, must file a partnership return (ie, the LLC is not considered a single member LLC disregarded entity).

another single family home?

If you're getting started, I'd suggest focusing on single-family homes in growth areas with strong population trends—let me know if you need help finding the right deal!

I am considering purchasing empty lots priced roughly $10-15K below market value.My plan is to offer owner financing for the land.These lots have water, drainage, and electric connections available, and mobile homes are permitted.The area is experiencing significant development, with the lots surrounded by new single-family homes.I would really appreciate any advice, feedback, or suggestions.Thank you

I am primarily interested in single family homes (to start out at least).

A majority were single-family investors.  

I'm currently in single family homes and apartment buildings in central and west Texas but have been evaluating a few residential assisted living homes + business / license to purchase in Austin and San Antonio.

I am partnering with another investor who owns 4 single family homes in that vicinity.

To get started, consider focusing on house hacking in California with properties like duplexes or single-family homes with ADUs, or explore out-of-state rentals in landlord-friendly markets like Ohio or Georgia.
