Often, residents/market participants in a particular area don't even agree on he boundaries of their own neighborhood or what the defining characteristics of their own neighborhood are. Its a very tough issue that we tried to address as the data guys at Fannie were salivating about the possibility of tracking defined/standardized neighborhood data. The other problem is that neighborhood boundaries can change over time
Neighborhood means a lot of different things to different people. I would never define neighborhood on the basis of census tracts, which imho are totally meaningless division in the county I live. In the two counties adjacent - very rural Oklahoma counties - there are only "census blocks" - 4 per county. Again, the demographic does not match the Census tract. One county only has 2 towns over 1,000 in population. The other has 3 but it also has a large lake and as such an entirely different demographic - non-native retirees v. indigenous native American farmers and ranchers. And between the two is a large development shared by the two counties which is an el cheapo development of mixed manufactured housing, log cabins and typical SFR's.
Trying to cubby hole such mixed properties into neat little small packages won't work. Even when I was still doing secondary market I refused to work any rural Oklahoma property because you get insane stips like asking you to find "closer" comps from towns like Chewey, Proctor, Kenwood (which is an Indian Reservation, not a town per se), and other towns of under 100 population.
"Neighborhood" is an artificial creation of the appraiser or someone who speaks in generic terms about a "neighborhood" - a group of "complimentary uses"...what does that mean? A bunch of cookie cutters in a single subdivision? Or a defined community with a common tie, such as school district or city limits complete with small retail area, commercial/industrial areas, etc. And most of us are guilty at one time or another of PFA the percentages- 40% residential; 20% vacant; 10% industrial and 30% other...After all, who wants to go into a defined area, and pull up every parcel and A-determine if it is associated with one or more other parcels; then count physically which have dwellings, which are vacant and which are non-residential?
Another thing is I see is that every community is 10% renters

Every one. Nevermind the census summary claims 30% non-owner occupied. I see renters under-reported in 90% of appraisals. I've probably been guilty of it too. OTOH, what data source is going to get accurate accounting for the explicit neighborhood you defined? If your neighborhood isn't exactly the same as the census demographic neighborhood, the number could be different.
My all time favorite was an appraisal that defined the neighborhood as all of this county; reported the land use % as 80% residential, 20% vacant (roughly one-third is in a national park) and probably15% of the properties on the assessor's roll is commercial or multi family or agricultural.
Government owned land is commonly not even considered in a lot of appraisals I've seen over the past 2.5 decades. Ditto for lakes, ag land, etc. What metric is used? Numbers (gross)? Acreage? Value $ worth? It is all a big joke.
