Some buyers don't like a long commute to their place of employment. Easy highway access can play a role into their buying decisions. Hwy has not impact on your property value

That's a great question. I would think in most cases it's neglible, unless it significantly reduces the communte time for a majority of the people who live there. Highways can create bedroom communities, but my guess is 161 won't significantly increase values in Cedar Hill, because there was good access already with the other highways. The places I think highways could help are for example at the North end of the Dallas North Tollway. They don't have any highway now, and adding it will significantly reduce commute times for many people. That's just my 2cts worth. It will be interesting to see what other people say. You might be able to get a study from the Texas Dept of Highways to see their stats. You might also get something from the economic development people in Cedar Hill. My thought is if people commute in Cedar Hill to jobs it's probably more likely East and West and less so to the North.
