In this area, where the listings are is just the nature of the market. We actually have more on the market in central and north Arlington (Martin HS-181, Lamar HS-180) than we do in southwest Arlington (Summit HS-83). A little of the Martin area would be considered SW Arlington but not many.
Texas is notorious for shifting soils but it typically produces hairline cracks in the corners and above openings that change with the seasons. Nothing major. If you have concerns about a foundation, don't hesitate to have your agent call in a foundation company that they trust to evaluate it. Most foundation problems are due to lack of water during our hot summers. Very preventable and correctable, to a point depending on the severity, by getting water in the soil around the house.
About a year ago the fracking really slowed within the city limits. You still see the equipment go up here and there but not like it was four years ago. Texas in general, especially N. Texas, was not devastated by the recession that we just went through and much of that is attributed to our oil and gas resources.
If you have other concerns, feel free to contact me. Happy New Year!
