I would start with them.I am not based in LA, so I don't know your exact laws, but I think I can still provide some initial direction for you to find answers, and maybe offer an idea to research.  

My name is Ken, I'm brand new to real estate investing, still trying to learn more about the in and outs.  

I personally use Hostfully and their support team is great!

I did some research first to see if they are even legitimate and what their reviews are like.

Myself personally I'm invested in Buffalo and NYC, but that's because it made sense for *me*. 

Will the title company put this property under our LLC name, and won’t be required to legally inform HUD/tax authorities. - will it influence property taxes once we move to conventional loan in 3 yrs? 

I find it's very personal, and dependent a lot on your goals, resources, risk tolerance, location, experience, etc.

A couple strategies that could make sense for a younger person without experience could be a live-in flip or a house hack.

As a beginner, I would personally get my feet wet with something a little less risky without a balloon payment like that.

I will reach out to you personally, please keep an eye out in your inbox.
