Austin area is exploding. My son just sold his house for 2.5 times what he paid up near Leander. It was a tech guy out of Cali. His whole neighborhood is that way. Selling like hotcakes.
I have one son between Georgetown and Liberty Hill, just North of Leander, and #2 lives in Cedar Park. Housing prices are just plain outrageous. What's even more amazing is the rental market.
Did your Son move out of the area? I love it there. In fact, will be there for a few months starting late in June.
