Best financing for dupelx

[Lara Ishtayeh]

New to investing and have questions on financing options.
What is the best way to finance duplex? I'll be living in one side and renting out other, but I want to be able to move out of it in under a year? I have enough to put 20% down and make investment property but this will be my first primary residence so I might as well live in this one for a short time and get out as soon as I can.

Thanks!
