Ken is exactly right. The purchase agreement/sales contract tells us a lot more than just a sales price. It also tells us if it is an arms length sale, i.e., not a sale where there is a bias or interest shared by the parties such as being family members, business associates, or close personal friends. That is not perfect but it is a beginning point as some of those mentioned may have an undue influence over one another. Also, it tells us the terms, which must be legal to the extent that the appraiser has knowledge to ascertain that information. And, it tells us what is included such as real property and real estate.
1. Real Property......The rights to real estate
2. Real Estate.......the concept of the physical location, it's boundaries, it's attachments, and how far below and above the surface of the earth that extends.
It provides the appraiser the opportunity to analyze whether or not it is consistent with market factors based on property type, location, amenities, and market reaction to those factors.
I do know that in most(very few) countries I have become familiar with, this information is provided to the appraiser or whatever they are called in their country.
And, it is required by the Uniform Standards or Professional Appraisal Practice (USPAP) that we analyze such a contract if it is available and explain what steps we took to secure it, if it is not available.
