A home is meant to be a depreciating asset like a car is.
A car and a home are two very different things, so they can't be compared here.
Even the land your home is on increases in value over time, and I've yet to see a home in good condition that's worth less than the amount it was purchased for. Unless you're talking about those ghost cities in China.
What exact reason would you give to devalue a perfectly good home?
