What does one buy first single family or small multi

[Angelo Llamas]

In order to diversify my portfolio I want to have cash flowing properties along side with heavy appreciating properties for equity growth. Now my question is to begin with is it a better idea to buy the cash flowing property first save my profits along with my W-2 job an then has time goes on purchase, say a single family property in a great appreciating area. Or do you start with the high appreciating property an as time goes on reap the benifits of equity an then purchases the small multi to protect yourself an have some cash flow coming in more so then the single family? 

Thank you
