Sell my single family to purchase a multifamily

[Nicole Collins]

Hi, 

I am new to Biggerpockets and Real Estate investing. I'm learning as much as I can right now on this site and reading books. I currently own a single family home that I bought in 2010. My Tenants pay $1500 and my mortgage is $1000. I want to starting investing in multifamily properties (I own one duplex that I live in and rent the other), so I am thinking of selling this home that I own $160,000. An identical home sold in the last 3 months in the area for $244,000. I would use this profit to purchase a multifamily property, that is a good deal of course. Any advice? is this a good move?
