I'm finding tons of gems in here.

If the property is located in California, you will inherently be "doing business" in California and subject to California income taxes (both for LLC and for you on a personal level).  

Like @Mehran K. indicated, FHA financing will require you live in one unit, presumably the 1/1 unit as you are a young guy, which, if already rented to a tenant for a year, will will be an obstacle in obtaining FHA financing, as it is a primary requirement for such a loan. 

Also be sure to adequately capitalize your LLC from the beginning, and don't guarantee the debts of your LLC with your personal assets to a bank or other creditor, because that also may mitigate the protections inherent in an LLC. 

Cash flow still isn't good, but I have a tenant going on 4 years who was in her previous place for 10 years and only changed to come to my cottage (it is cute and it is on the water) and she is currently covering my mortgage expenses.  

I'll chime in here after hearing all of your color remarks about people trying to earn an honest living.

Besanceney Hopefully you'll get a lender to chime in here, but in my experience and in talking to my lenders, it is going to be very tough to get them to include any potential income from your roommates into your qualification - especially if it is a single family home.

Even if it means not paying off the car loan.The way I look at this: If you house hack and do it effectively(I am including house hacking in here even though you didn't bring it up because I'm trying to recommend a strategy that will set you up for wealth building while buying your first house at the same time), you will be saving money on your monthly housing expenses from the rent of the other tenants(if you do it really well you may even cash flow a little).

I was living in my 6bd/3ba rent-by-the-room house hack with 5 other tenants, and she was living in her 4bd/2ba house hack with 3 other tenants.

However, you should know that the HOA management space is inherently fragmented and filled with a lot of outdated, smaller operators that may or may not be focused on your association’s needs.
