We figure we will be able to charge $900/month per side ($1800 total) but also do not know the first thing about becoming a landlord or where to find tenants.

I haven't seen all your finances so I don't know how it'll play out, but you need to immediately call your lender before you do anything that might further make it look like you're trying to buy a house with a credit card like it's 2006.

Go to the ones with the most reviews and see how booked up they are and what prices they are charging. 

I manage my properties, I carefully vet each tenant, I stay on top of maintenance and make sure my apartments are nicer than anything else nearby so I can charge top of market rents.

Seems like the attorney review period there is a get out of jail free card for both parties, don’t know how you get around it.

The landlord has been charging  approximately a much lower rent than that of comparable properties in the area.

It sounds like you do not charge more for a monthly rental, either.
