William Davis Realty
Its just a basic supply and demand. Less demand on the city due to the popularity is mostly the cause of the value on the homes. People in generally don't like to be far from Dallas where is most entertainment and shopping are. So if you go out of Dallas area, you will get a lot more for the money.
Another great area to look into is Mesquite. You can also get a lot for the money and its a cute neighborhood.
You can look into some homes in Mesquite here at http://www.findyourtexashome.com/mesquite/

Everyone is different, but you are right about prices.
At 200-300K you might be at the top end of the price ranges in Garland, where for example in Frisco 200K is the starting area of prices.
