What is the best real estate investing business structure?

All the investing literature I have read say to protect yourself from liability and taxes. I know there are LLC and Corp (S and C) which provide these benefits. The investing literature also says to use the banks money to leverage your investing (OPM). However, my lender will not provide a single or multi family home investment loan for a business (only under my name). So, how do I create a business structure that protects me but still allows me to get home loans.
