NEED HELP!!

[N/A N/A]

I'm 25 years old, single, have a decent job, and live in the same house I grew up in. I live with my brother. The house is in my brother and my name and is 100% paid for. We are planning on selling the house within the next two months. Our real estate agent says we will get 450,000, and we will then split the money and go our seperate ways.
I need some opinions on what I should do. whatever I buy, I plan on living there. Im thinking about buying a 2 or 3 family house and having the rent pay the mortgage. then after a few years, maybe buy another 2 or 3 family and live there, but still keep the other house.
I dont think I want to flip houses because I just dont have the time.Im not to sure about buying a single family . But I know for sure I want to make money. Can anyone give me some advice on what I should do? Or what would be the best thing to do?
