Smaller homes are easier to maintain. Anyone who has owned a house knows the amount of time, energy, and effort to maintain it. All things being equal, a smaller home requires less of your time, energy, and effort to accomplish that task.
Smaller homes are less expensive to purchase and less expensive to keep.
Owning a smaller house is mentally freeing. As is the case with all of our possessions, the more we own, the more they own us.
And the more stuff we own, the more mental energy is held hostage by them. The same is absolutely true with our largest, most valuable asset. Buy small and free your mind.
Smaller homes encourage family bonding. A smaller home results in more social interaction among the members of the family. And while this may be the reason that some people purchase bigger homes.
Smaller homes are in a wider market to sell. By its very definition, a smaller, more affordable house is affordable to a larger percentage of the population than a more expensive, less affordable one.
