Many young couples start out life together with few resources, and they often buy a starter home after a few years. They look for a place that will have enough room for them to start a family of their own, but it must fit within their budget. As the years progress, their family grows and fills in all the spaces that were empty when they first moved in. Appliances, flooring and even walls can wear out over the years, and improving their home or moving are the choices they face.
Even couples that buy homes large enough to house the family they originally planned often find that their house needs to be improved over the years, and they look for a good return on their investment. They want to change their space, update their appliances and make their home as beautiful as possible. Function is also part of the reason people make big changes in their home, and these can also add value.
