The car is most valuable when it is fresh out of the factory and brand new. The instant it's driven off the lot by its first owner its lost 30% of its value.

The subsequent owners will also get some good utility out of the car, wearing down the value in the process. Once it has 3-4 owners on it, future buyers become wary because of all the hands that have been on the car. Not to mention all the miles these owners have put on it. Eventually the car gets too many owners, too many miles, and it becomes clear to whoever owns the car that they have to call the junk man to take her away to the scrapyard to be retired and cubed, and trade her in for something new and exciting.

A house is valuable based on many factors. Including size, location, quality of the materials, and quality of the architecture. For many houses, the older it gets the better. As many new, young houses may be fresh, but they are not built well, and have little stability. Indeed, for the house with age comes maturity and respect. A well kept brick house from 100 years ago is seen with awe compared to the hastily constructed McMansion built 6 months ago. As the occupants live in the house the value constantly goes up so long as the occupant takes proper care of the house. In other words, a houses value is guaranteed to go up, unless the actions of an occupation cause it to go down. A houses value is so stable it can even be used as a retirement plan, as many occupants depend on the value of their houses to secure money into retirement. And more than anything else, a house is absolutely vital to raising children. A child without a house will have no childhood at all.

Of course, not all houses are winners. Cities like Detroit prove this. Why? Because society neglected these houses, and allowed them to rot. If society wants to build these houses and communities back up, they will need to invest in them to ensure they are allowed to grow and prosper, instead of ignoring them and allowing them to fail their communities.
