Data Organization - Housing

I've spent some time browsing for houses lately.  I would eventually like to own a home.  While searching for houses I know there are certain points that I will need to be close to. My husband's job, my job and perhaps a friend or family member.  I can't help but think that this is a very common need and that the housing or real estate sites should include this as an option. It should be fairly simple to add in points of personal interest and then create a search that includes a proximity search as well as all the other price, size, amenities type qualifications.  I realize that it is possible to do a search of an area code or even of a specific address, but it would be nice to have the data automatically triangulate some points and realize that you don't want to live south of point A if point B is to the north.
