There’s so much wrong information in this thread that I don’t know where to begin, and quoting specific posts would be a real hassle. So I’m just going to define some terms and hope that the appropriate posters connect this with the posts.
Inspection vs. Appraisal vs. Survey
An inspection involves examining the structure with the intention of revealing defects that might affect the price or desirability. A good inspector will not only uncover and point out what a buyer or seller might not know, since he typically knows more about stuff than most buyers. If his expertise is insufficient, he may recommend further inspections by more qualified people. The bank doesn’t much care about this detail, and rarely orders an inspection.
An inspection may or may not include testing. Refer to the listing contract for this.
An appraisal is an attempt to place a reasonable sale value on a property, nothing more. All banks will order one before finalizing a loan since it is their money that is being risked, and they want to minimize potential loss.
An appraiser will compare similar properties that have recently sold in order to establish a value. An inspector will not.
A survey is not an inspection nor an appraisal. It usually refers to a map of the property with regards to the boundaries and location of objects (houses, wells, fences, etc.) Surveys are highly recommended in rural areas or where there is likely to be a property line dispute. City properties are rarely surveyed.
Procuring Cause
In the case of the agent who put together MLS listings in a flyer, then presented these to a prospective buyer, he was probably the Procuring Cause, and is entitled to some of the commission (assuming he is properly licensed and can prove he introduced the buyer to the property via the brochure or other means).
If I sent a prospect some information about a property and he called his cousin to act as an agent for him, that would be fine with me, but if I am the procuring cause, I deserve to be compensated as the “primary” reason the property came under interest or negotiation. His cousin might end up serving for no commission, or trying to get additional commission external to the MLS.
