Would you chose between renting a property or flipping it?

[Allan Quintela]

Hey BP! I'm currently in the market to buy a house for me and my gf to live in. I'm torn between buying a duplex house and living in 1 side and renting out the other, OR buying a single family house and living in it and hopefully flip it and resell within  a year or 2. I do construction work myself so I would be slowly upgrading the house while I live in it to hopefully sell for a nice profit then redo everything.

If you were in my shoes or if you had to chose between one, which would you do and why? 

My goal is to own many properties and flip houses and make a living out of it, incase that helps. 

Thanks all!
