How much can I charge for rent on a new build spec home

[Daniel Taki]

I'm wondering what sounds reasonable to charge for the two extra rooms in a recently purchased new build spec town home.   The townhome is across the street from the metro rail in Austin, Texas.

Details:

1st Floor: First Floor

2nd Floor: Second Floor

Here's a link to rentometer for 3 bedroom apartment/townhome rentals in the vicinity of mine. Rental Comparables

What do ya'll think this is my first home buy and also first landlord experience, so any tips or things I might want to know I appreciate.   Also thinking about AirBnB for one of the rooms.

$600 with all utilities included would be reasonable.
