Most people buy a home for very specific reasons. Those reasons typically have more to do with life situations and very little to do with market considerations. When you marry, begin planning a family, or look at retirement you might suddenly find yourself wanting to buy a home. Because of the importance of these life situations, you might pay relatively little attention to such things as the cost of borrowing. These things are often viewed as necessities at such times. That is why it is quite common for people to negotiate a mortgage as best they can then in a few years, find that loan rates have dropped considerably. Many home owners will accept the costs associated with mortgage refinancing in order to save themselves larger sums of money over the long term.
