Below are the two best sources on the subject.
Since I was not behind the formation of the 1004, I can only speculate.
I believe neighborhood was really ment to mean subdivision for the most part for the 1004. If you read gse and FHA guidelines, they wanted the appraiser to put in the subdivision name as the neighborhood. Also, they used terminology such as arctectual....
It makes sense to use the subdivision as the neighborhood ....it's easier to catch appraisers when they outside of the subdivision to use superior sales.
1. Predominant prices
2. Easier to decern a over improvement or a under improvement.
3. One mile radius guideline came from? How many neighborhoods are actually 1 mile? Few. Most subdivisions are tho.
The issue has always been the difference between what the gses/FHA wanted and what the appraisal text said a neighborhood was.
Also, what about rural markets? Really are no subdivisions in rural markets....good example of trying to put everything in the same box..form.
That is why many of the older appraisers would put in 100% built out and all data would be from the subdivision. *technically they were right if using the 1004 form. But was not right per the appraisal text books.
Appraisers make a distinction between the neighborhood in which a residence is located and the market area in which comparable properties will be found.
