Why Inspect ...

Although inspections are not a requirement, it should be as important a part of the transaction as the appraisal and title search. This allows you to be an informed buyer.

From the Sellers and Realtors point of view, inspection ensures that any future problem will not be blamed on any non-disclosure. Also, most homes have some minor problems, even if they are only a few years old. However, there can be addressed and allow the sale to go through.
Having someone who is reliable and independent will benefit both sides.
