Advice on a potential deal Appreciation Vs. Cash Flow

[John Hyun]

I am a newer investor and I need advice for a potential deal.  I currently own a 4 unit building and just had an offer accepted for a duplex in the Long Beach area, but now I am having second thoughts after crunching the numbers.  My strategy was to refinance cash out on my current property and put a down payment into a conventional loan for the duplex. My hope was to have more cash flow in total after the 2nd property, but after evaluating the comps in the area I realized I would be cash flowing about the same.  So essentially I would be cash flowing the same, but will have 2 properties.  It seems to me my strategy would be appreciation rather than cash flow for this deal.  Considering the Southern California market would you go for this deal?  Appreciate your time and input
