You can find quality new homes with spacious floor plans and quality construction in your local area. It is always recommended that you purchase a quality home over a spec home.
An Austin new homes will be cheaper but the construction techniques and the materials will also be inferior.
True, you will save money up front but in the long run it will cost you more money because you will have to repair things around the home more often than if you purchased a quality home. Therefore, if you have the funds you should always choose a quality home first.
