Buying a home or investing into a property?

[Phillip Gonzales]

Hello so I am in a dilemma and need help. I am expecting my first child next year and have been renting my own little condo, but I have been wanting to purchase a property before I found out I was expecting a baby. My fiance wants a a single family home for the family, but I wanted to do a duplex or invest in a property. I am just a bit confused and a little worried I am not making the right "investor" decision. Any insight or experience will help. 

Needs as listed 

1. home I am going to own

2. will sell or flip property within 5 years

3. Not sure which funding I should pursue 

HELP!
