Should I buy a duplex or single family?

[Evan Hauler]

Hello everyone! I am having trouble running numbers for my situation. 

I am looking at buying a 350k duplex in cash and living in one of the units. The other unit rents for around 1000-1200. Does this produce a good enough return to buy this, over just living in a single family over around 250k. I am doing numbers and running around on them, can you help me? Thank you guys so much.
