An existing home can be cheaper to buy, but in the long run they will usually require more maintenance which will increase the cost. When buying a new home it should not require any maintenance for many years because they generally come with aluminum siding, and pressure treated decks. However a price negotiation can be done with an existing home.

New home have new insulation, new windows, along with efficient heating and cooling systems. Usually when buying an existing home they use more power, have older windows and are less energy efficient.
