Just Bought My First Duplex (House-Hack), Now What?

[Trent Ford]

Hi BP!
I just bought my first property! I am super excited, and also flooded with questions! Basically now is the point where all the theory becomes reality, and I want any and all advice you may have for a first time landlord.

The property is a recently remodeled duplex in a suburb of Dallas, TX, with a tenant currently in one of the units. The tenant has been month to month, as the seller didn't want the buyer to inherit a long lease. From the state of the unit, the tenant seems to be very clean and has taken good care of the place. 

However, the rent that the tenant is paying is a few hundred dollars less per month than what I think the unit could/should generate. How should I handle possibly raising rent for a current tenant? The tenant also has 2 dogs. I don't guess I can charge a pet deposit, as she's already in the unit?

Any other advice or words of wisdom you might have for a new landlord would be much appreciated! 

Thanks in Advance!
