As I've evolved my philosophy on this I'm coming more to the opinion that a SCA grid can never be more than a plausible mathematical (quantitative) explanation of the most reasonable qualitative analysis of the situation.
The intent of the practices and methodology applied to this appraisal problem is to create a predictive model of the subject’s market value. Quantitative indicators from available market data serve to build the model’s framework. Qualitative logic applied within the framework provides support for the reconciliation and solution to the appraisal problem.
The appraiser utilizes two predictive models as primary value indicators. The quantitative model (the form sales grid) and the qualitative model (ranking of the subject within the sample).
Comparables sales are presented in the form's grid and adjusted quantitatively. This quantitative predictive model provides a primary value range indicator that is considered in the final reconciliation.
The qualitative model (subjective ranking of the subject within the sample) takes place throughout the sales comparison approach and compliments the quantitative model. The primary reconciliation process takes place in a qualitative analysis wherein the subject and comparables are ranked relative to each other based on overall utility, condition and appeal. This process strongly replicates the thought process of a typical buyer. The form's quantitative grid serves to present a snapshot of the market and attempts to bracket the subject within it's relative rank in the market.
