You should definitely do more research on the true costs associated with renting a house out before you go that route. At a minimum you need to factor in budgets for repairs and vacancies to your numbers to see if you will actually turn a profit on the house. Check out the Real Estate forum here and/or real estate specific blogs like BiggerPockets before you get too far down that road. If you factor in 10% each for repairs and vacancies, which I believe are pretty common numbers, then you will actually be renting your house at a loss if you are at the lower end of your suggested rental scale.
I did something somewhat similar - I had to move for work so I rented out my house, figuring that I couldn't afford to sell it at the time (2009). I had great tenants the whole time, but when I finally sat down and ran the actual numbers I found that my rental property was COSTING me over $300 a month. And that was with good tenants that actually made improvements to the property at their expense. I would not consider the experience a bad one, but I should have run the numbers to see the true costs before I made the decision to rent out my house. It could be a good deal for you, but definitely talk to people in the landlording business and run the numbers before you get into it.
