No money down vs. saving for a down payment.

[Brandon Smith]

I have an emergency savings account that covers 3-4 months of bills. Now that I've built that I want to start investing in multifamily housing. I don't have a down payment. Is it worth finding a lender for a down payment and get started now, or save the money for a down payment. (This may take a few years). I've read a few books that cover no money down options but I am looking for someone with experience to shed some light on the process.
