Health and Safety. Recent discoveries and statistics have changed building codes and product specifications. Some building materials and practices used long ago are no longer acceptable in newly constructed homes. Some safety items can be easily added or altered in older homes. Hand railings can be improved inexpensively. Smoke and carbon monoxide detectors can be easily installed. Other health related concerns, like asbestos and lead, can be quite expensive to correct or remove.
The most important part of purchasing an older home is having a sale agreement covering inspections and testing and hiring experienced professionals to evaluate your potential purchase. With a contract protecting you from major defects, you can focus on other important aspects of home buying like deciding if the location, size, character and potential of the home is suitable to your family and lifestyle.
