Living can be a broad question, do you want to commute? Do you require anything specific for your apt, garage, pet friendly, near bars, etc?
MSR is a good track, straight rental is expensive but sign up with some of the driving groups and a day event can be 150-300 bucks which is a lot better. Plus there is also Texas World Speedway nearby to Houston.
