It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

I’d try to re-rent it as soon as possible.Next question for you is: if your original contract supports your claim (but be sure that it does), and you still have the security deposit, “charge” against that.

I'd expect that the excess mileage charges would be a killer.I think next time I'd so something like a Jeep or a Honda SUV. 

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.
