[Source: Lifehacker] — Optimal Home Location is a Google Maps/Zillow mashup tool that helps you calculate the central location between all your commuting destinations. After plugging in the six most frequent places you and your family commute to: work, school, other family members, etc., Optimal Home Location will crunch the numbers. The map it returns will show you the best place for you to live in order to minimize your commute times.
The service is really handy, although not without its quirks. It cannot take into account anything beyond physical distances for instance, leaving you decide if the area is a safe neighborhood and whether or not it’s cost effective to live there… On top of showing you the optimal location, it also allows you to compare commute times from various addresses you are already have in mind and show the location of local features like schools and libraries to help you pick an ideal locale.
