Took the leap, now how to give a 60 notice!

[Andrew Caballero]

Looking for your advice! 

My back story: Long time BP lurker, first time posting. Currently about to close on my second home ( bought and sold my first single family home). this is my first investment property as it's a duplex with both units filled.

My problem: With both units filled and me using a VA loan i have to live in one of the units for at least a year. I feel so bad that someone has to go. Unit #1 has a lease out to October and unit #2 is month to month. I'm going to give unit #2 a 60 day notice to of vacate ( Is this the right term?). How do I go about this and what if she doesn't leave after said notice? If she doesn't leave, I'm homeless as I already gave my notice to my apartment. Also what is a good resource I could use to learn how to landlord? Things I'm interested in learning are how to write a lease, how to raise rent to market value and how to collect rent. Thanks BP community!
