I am guessing you are looking to rent over buy?? Trulia rentals certainly is an option, but the clients I talk to who are wanting a rental, I point them towards Craigslist, Denver Backpage, Hotpads, Trulia and Zillow. Unlike the homes for sale where they are entered into an MLS, there isn't any database like this for rentals.

You will have to factor in HOA' s, insurance, taxes, but you have the tax rights off's also which make home ownership more appealing.
Call me if you want to talk more in details about what you are looking for
