A well-built property can last for hundreds of years, but many of its components must be replaced or renovated regularly during this period.  When purchasing a new property, it is important to include within your budget an amount for repairs and renewals to the property itself, in addition to the largely cosmetic changes most new owners make to their properties.  The following list of approximate life expectancies of different building components is published by the National Association of Home Builders (NAHB).  A list of estimated replacement costs is available for free download.
