Trying to be Multi-Family investor

Hey Friends, I am absolutely new the real estate investing and recently started searching for various options to invest in including methods to finance.

I am based out of Tampa, Florida and looking for townhouses or multi-family to start this journey.  Are there any suggestions, advice or guidance for this market from the gurus here, including how to start with absolutely no money in hand.  I just bought my own residential house and therefore all cash in hand went for that down payment. 

Any advice or guidance will be helpful.

Thanks,

Rohit
