It's easy to confuse some professions you may deal with in the home buying process, specifically, the surveyor, appraiser, and home inspector.
A surveyor finds, marks, and/or maps the legal boundaries of a property.
An appraiser determines the (general) value of a property, based on details of the home and recent prices of similar homes sold in an area.
A home inspectors job is to to closely inspect the items around, on, and in the home itself, noting defects and creating an in depth list, a.k.a. 'report'. This report informs you of what you are getting, and the condition it is in, for your money. For more on this process, and *when* it should happen, click here:
