Averagely, home owners move from one house to another every five, six, or seven years. People who have lived in their house for almost some decades will never understand why some people do the moving so often. There are many reasons for that and some of these are enumerated below:
Bigger family. When you were just turning to legal age, you needed to move out of your parent's house. So, you've decided to move into a small apartment. But when you get married, you moved to a bigger place. This place is just enough for the two of you and your upcoming baby. But as you get more kids and as they grow bigger, you realize the need for a bigger house. And so, you are finally moving to a bigger space again.
Financial matters. For better or worse, chances are you get to move to another place because of money. For instance, some people who were promoted or had many profits from their business became suddenly capable of buying a bigger or better house. Of course, they will move to that soon and will enjoy the lifestyle they've been dreaming of. However, some people with no luck might been bankrupt or lost their job. They have no other option but to give up their house and move to a smaller space so they can keep up with the bills and their credits.
For whatever reason, people choosing to move continue to increase. But it don't matter much because as long as you move with convenience and happiness, then home is in wherever place you are.
