Most buyers will have the property inspected by a licensed property inspector within the time frame that was agreed upon. Some buyers will have several different inspectors inspect the property, if they wish to obtain professional opinions from inspectors who specialize in a specific area (Roof, HVAC, Structural).
If the agreement is conditional upon financing, then the property will be appraised by a licensed appraiser to determine the value for the lending institution via third party. This is done so that the lending institution can confirm their investment in your property is accurate.
The Closing Attorney.
The Closing Attorney’s job is to examine and insure clear title to the property. After researching the complete recorded history of your property, they will certify that your title is free and clear of encumbrances (eg. mortgages, leases, or restrictions, liens) by the date of closing; and all new encumbrances are duly included in the title.
