Like all things owned, there is a resale value. To protect these investments, you need to take care of them. Your home is a large investment and to keep it that way you choose to update to modern appliances, add on to your space, or at the very least you make the necessary repairs needed to keep your home running. You have a nice car, you keep up with the routine maintenance such as the oil changes, not just to keep it running but also to protect your investment. What if you decide to sell your car or your home? Are you ready? Most people are NOT.
