Two different approached required-that's why there is a reconcialtion line on the form-Also why all tree approaches if applicable are required-what is being done is the income approach twice and its being thinly veiled in the guise of a sales comparison approach.
Gotta be careful of what you post!!!
From the AI's course: General Appraiser Sales Comparison Approach-
Techniques for Estimating Adjustments
Quantitative Adjustment- In the sales comparison approach, the process of making numerical adjustments to the sale prices of comparable properties, including data analysis techniques (paired data analysis, grouped data analysis, and secondary data analysis), statistical analysis, graphic analysis, trend analysis, cost analysis (cost to cure, depreciated cost), and capitalization of rent differences; usually precedes qualitative analysis.

I think there is confusion here that one approach automatically excludes another. That isn't the case since each approach is based on how the market reacts.
If I have a 4-plex that gets 10% higher rent because I'm next to a lake, and consequently that 10% is reflected in my GRM x income, what is the appropriate adjustment for the location difference? Is it not the GRM x 10% rental difference? Not hard to calculate a location adjustment
if the market values it as a rent (income) difference, is it?
Now, what if we have the same situation but there is no rent difference? An appraiser may assume that being by the lake is a superior location... but it isn't recognized as such by renters (users) of the property. Will buyer of these properties pay a superior location premium when the market doesn't recognize any additional income for the location? Again, this is a sales comparison approach problem that uses income analysis to determine the appropriate adjustment for units of comparison.
Now, what about the situation where I need to replace my roof? Do renters pay more if the roof is new or not new? My experience says no; roof age is not a rental influence (positive or negative) but is a purchase-price influence; if I need to replace the roof, I'm going to consider that cost in my pricing of the property. That would be an example of a non-income component that has an influence on the sales comparison approach... but wait! It also has an influence on the Income Analysis too!
So, I wouldn't get too hung-up on trying to create an artificial division between approaches when the actual market does not make that distinction. More important is to recognize
how and why the market is reacting to differences and then making the adjustments based on those reasons; without doing this, it is difficult to support the rationale for the adjustments, no? (Or worse, the appraiser is making adjustments for differences without understanding why it is so) :new_smile-l:
