Let's see if we can profile Mark from his housing request:

Looks like he wants elbow room
He likes to be around water
He must live with a few people; 4+ bedrooms
Has at least 2 vehicles
Definitely anti-social
Obviously has no clue what it's like to mow the lawn in Texas in July!!

I'll leave the pricing to Jack. My brother's place I would estimate at around $300,000 in Sugarland. How they are priced outside of town I wouldn't have a clue.

Good luck, Mark!
