I don't think you are in the right position to get your own place. In many states, 18 years is the legal age for somebody to get his own place. I think you should wait until you reach 18 in order to get help from the government.
gov assistance is for those who don't have other options. its a last resort the help people get through tough times. using it the way you are suggesting is called mooching and is what gives opponents to having social programs ammunition to shut it down.
