My first Rental Property and i am lost....

[Jason Law]

I bought a new house this year and want to turn my old house into a rental property. I have renovated the house and ready to be rented except, I don't know what to do now. who do I contact about writing the contract? I am an IT guy and fairly skilled when it comes to creating a solution through the internet and I was thinking to create a website where possible tenants can fill out an application online that way I can choose the best tenant but I don't know what questions I am legally inclined to ask when it comes to that application. can I ask where they work or how much they make which from my point of view it is critical? 

Is this something that normal landlords do or am I going through a newbie phase?
