Knowing a home's original age is only a starting point to anticipating potential concerns. Not all older homes are going to have issues, but the probability of identifying deficiencies or hazards are much greater. A prudent first step to reducing your buying and ownership risks is retaining the services of a licensed, experienced, and knowledgeable Home Inspector.
Although building science, practices, and material technologies have been improved overtime, older building materials and techniques still remain in service with older homes. Older systems either reach the end of their serviceable-life, require improvement, or removal and replacement from future service based on known issues or risks. For example, design flaws and non-performance issue ('leaky condos' in BC), and health and safety risks (increased probability of electrical fires due to aluminum branch wiring and soil contamination from underground oil tanks). Older homes, especially those that have not been sold for decades, or not renovated/ improved at some point in the past, are commonly going to have defects/ deficiencies that a home buyer needs to know about prior to purchase.
