Earlier quoted context omitted.
don't do it to save money, because you unlikely will. lower cost of living is associated with a lower quality of life. things are cheaper in other places because they have less quality. what you save on some things, you end up spending on others. before you move somewhere, make sure you like it there regardless of the cost or quality of life, because if you don't you will end up spending more on things to compensate…
That is not always true. Cost of living in Houston is lower than in LA. Is life worse there? Is quality lower?
it really depends on what you consider quality of living. to me that includes access to interesting activities, people etc. if i don't get that, i will do something else to compensate. in houston that could mean more travelling. so the money you save on the house you then spend on airplane tickets or on gas for your car.
not everyone is going to be the same. it could be that you absolutely love living in houston, spend all your time hanging out at the space center, or some other local activity that is not expensive and really do save money.
but what i said actually applies more for living in a different country, because i assure you, at a minimum you will miss food from home and spend money on imported food or going to restaurants.
