It is logical and only natural to conduct a building inspection of a building that is to be bought. However, in many cases it has happened that lack of proper knowledge or expertise in construction nitty-gritty's have led to losses for the buyer that could have been easily avoided if during inspection the buyer did consult to relevant experienced professionals.
A building inspection is not just about things that are visible to the naked eye. In most buildings, things that are visible are often in good shape and order that give an impression of a well-maintained worth buying property and often enough the buyer has ended up spending substantial amounts after the deal towards upkeep of the same property. In such cases, it is the condition of the things that are not visible to the naked eye that are the culprits. For example, a hairline crack in a beam can be overlooked by a layman for whom it might just appear to be a crack in the paint. Only a trained and experienced professional will be able to make out the difference in such situations.
