My suggestion is that you do a combo. of both, however to hold them in an LLC is not part of my recommendation.  

I would suggest start saving for your down payment and reserves for your property. "21 years old, $30,000...where to start" is a little vague.

I was going to suggest ignoring the voice mail and that the former tenant filing a police report was likely to end exactly the way it did.My dad was a "building superintendent" (fancy name for janitor) for three buildings in Evanston, Illinois. 

If not it probably wouldn't be suggested to do you first one OOS because your not over seeing anything of the project.

I would like to contact the real estate agents for each property, what kind of questions do you suggest I ask?

. + Property locations: - Pleasant hill- hayward+ Construction experience potential (what you can learn about from these projects):- kitchen and bath remodel of course - room addition- ADU building- New Construction - Lot splitAny suggestions and constructive criticism are always welcome.

I would suggest starting with licenses in states you need.
