Duplex multifamily pros and cons

[Virgilio Garcia]

Hello all, 

I wanted to get some advise and opinions of multifamily homes as a primary residence and investment ( tenant pays off mortgage).

i have an idea where i would go out and find a motivated seller with a 50% occupancy where i can take up the other 50% becoming a landlord.

I know this is going to take some hard work and i am willing to put in the work. I want to weigh the pros and cons, best case scenarios and worst case scenarios. 

Thank you all.
