Looking to invest in Commercial RE. Financing?

[Will F.]

Hi so I've been investing/managing several small residential units for about 10 years.

I have a family member who is willing to put in $300K cash for investing in a commercial RE property- most likely a multi family in Southern California- Los Angeles area.

I was wondering how much of a loan we could get with this $300K down, very good credit above 800K.

Also I was wondering if I could partner with him with an S Corp or LLP. We were thinking of 80% for him and 20% for me. I wasn't sure if I would do an LLP

What should I do? Anyone recommend a book or resource for multi-family investing where I am the manager/ partial owner and I partner with someone who has more cash.

I could also possibly pull some cash out of my residential properties for this.

Also any recommendations on areas within the Los Angeles area to invest?

Thank you
