Any building, big or small, is really a complex engineering system, an amazing machine. It took very specialized expertise to design and construct the electrical system, the plumbing system, the heating and cooling components and their distribution systems, the foundation, the walls, the roof and so forth. It then took more specialized effort to architect the house and put all these pieces together to work as a unit. With anything this complex, things are bound to go “out of whack” over time. Sometimes these problems are minor, and sometimes they can be very significant costing hundreds or even thousands of dollars to correct. Sometimes the different systems and components interact with each other in ways unforeseen. Worst of all, some minor problems can escalate into major problems if left uncorrected. With a thorough property evaluation, you can find out what the “state of health” of the property you are thinking of buying is before you buy.
