I saw the other post about Southlake, TX. I agree with the person that replied that Southlake is beautiful and a great community in Texas. My only problem with Southlake is that their average home price is pretty high. If anyone knows, please correct me if I'm wrong, but I think you're looking at the $400,000's there for a new home.
I live in McKinney, TX which is about 35 miles north of Dallas. McKinney is the county seat for Collin County which has Frisco, Plano, Allen (all names of towns I'm sure you'll quickly become familiar with!) in it. I love McKinney, I am new to TX and have only lived here for 3 years. McKinney is changing before my eyes as far as growth goes. New stores, streets, schools every month. McKinney also has great schools and our homes range anywhere from the $100,000's to +$1,000,0000 and up. McKinney also has a town square that has great character. PM me if you need more info!
