what bank would let me borrow the money I need to start investing on income propertys or what I need to show them to get the money
I believe you're missing the very first step of investing in real estate! Where's your deal? Do you have the 20-25% down payment & 6 months cash reserves? Also, are you certain that you'll need an LLC? You're in California, which has annual filing fees that approach $1000, even if you don't use the LLC for anything this year.
It sounds like you need to talk to commercial brokers, an accountant and a real estate lawyer if you have the funds ready to invest in a commercial property.
