An older couple may have such preference as well as a growing family with small children. Yes you could use fancy websites that map properties online but this does not compare to the onsite experience.
When you are scouting for your next neighborhood do not call every listing agent on every sign unless you are prepared to track who is calling you again and again. The ideal situation is to get a list of properties from your real estate agent and drive by the area yourself. You will have all the time and space you need to look over the area.
If you see houses for sale in that area not on your list, write down the address and speak to your agent about it. It probably was excluded due to some feature you did not request like no finished basement, etc.
