My initial thought is LTR single family or small multi, though I'm not opposed to short or med term rentals.My primary question has to do with LLCs. 

Multi family properties on the other hand tend to be more lucrative with numbers, especially if you are open minded to different strategies.   

Very hard to find multi-family properties that cash flow in this A market. 

I'm currently looking to either buy a turn key multi-family or BRRRR a multi.

Also the opportunity cost of not deploying your capital in an investment vehicle yielding more than 7% is high. 

Focus on smaller single-family homes, condos with low HOA fees, or multi-family properties in these regions, and build a reliable local team of agents, property managers, and other professionals to ensure a smooth investing experience.

Applying that to RE investing, most would agree your first FHA loan should be a multi-unit house hack.

For your GA LLC, filing correctly is crucial since you're based in CA and may need to handle multi-state tax filings.A real estate tax accountant can guide you on deducting renovation costs (likely capitalized rather than expensed for a flip), managing depreciation for investment properties, and tracking expenses related to your flip.

I’m trying to buy a second multi family.

Generally speaking, with SFR or small multis, I just rely on the lease/rent roll (and some form of proof of payment; i.e. bank statements, deposit receipts, tax returns, etc.).
