Collin mentioned a local bank that is keen on having Dr.s as clients, Endeavor is a local SoCal business bank, others could be agricultural or manufacturing oriented...some in the news recently for failing were VC and crypto centric.

@Josh Ball mentions, there are issues with foreign investors but, nowadays, it's not necessarily on the tax front anymore.

@Rey Magana Welcome to BP.You didn't mention what kind of investing you are interested in.Is it singlefamily or multifamily?

I've helped a lot of investors in your area, and I find that many of them end up purchasing rentals in the Central Valley for the very reason you mentioned.  

As an agent, you are really going into business as you mentioned for yourself with an added layer of support though.

However, if you partner with the right one, they will be instrumental to your real estate growth.As @Angie Keefe mentioned, your bookkeeper needs to specialize in Real Estate or thoroughly understand the industry because it is very balance sheet-heavy.

But as mentioned.

I hadn't even mentioned having my bank investigate.

As mentioned above get involved locally. 

House hacking is still one of the best ways to get started, especially with an FHA loan, but as you mentioned, competition for good multi-family deals has been tough.
