Move ... Improve ... or Relocate?

The conventional question regarding whether one should move, improve or relocate typically occurs when either a home seller or sellers are attempting to resolve some of the following issues: 

• Should we put in a new kitchen, go through remodeling stress ... or just buy another home that has the kind of kitchen we desire?
• Should we, now that we have two additional children ... build an addition, or buy a larger home?
• Should we remain living here because our children have lots of friends, and we like our neighbors, and just put up with our backyard being excavated for a pool, or sell this home and buy another home with a pool?
• Should we run the risk of over-improving our home for the neighborhood ... or move up?
• Should we take out a home equity loan for the improvements ... or buy another home with a new mortgage?
