true cost

A concept that calculates the total cost of owning and operating a home taking into consideration:

  • Mortgage of the home

  • Operating costs     (including the water, gas, and electrical energy use in the home)

  • Maintenance costs    – Maintenance costs can be reduced by purchasing durable products that are low in maintenance. These products may cost more up front, but provide a return on investment by needing to be serviced or replaced less often.

  • Cost to health   – A home can be designed and built for a healthier living environment. Everything from the chemical composition of building materials to the harboring of dust and mold affects indoor air quality which can greatly affect the health of the occupants.

  • Cost to the environment     – The issue of environmental impact is becoming more critical. We can no longer take for granted our planet’s resources. We need to become more responsible in our building practices as a means to sustain our planet and ourselves.
