[STEP 1: Pairwise Comparison of Evaluation Criteria]
When comparing “price” and “size,” which is more important to you?
Rate on the following 9-point scale:
1: Both items are equally important
3: The former is slightly more important than the latter
5: The former is more important than the latter
7: The former is considerably more important than the latter
9: The former is absolutely more important than the latter
For example, if you think “Price” (the former) is “slightly more important” than “Size” (the latter), select “3.”
Also, if you think “the seller, construction, and management companies” (the latter) are “more important” than “the specifications of the common areas” (the former), the rating would be “1/5,” which is the reciprocal of “5.”
[STEP 2: Pairwise Comparison of Evaluation Criteria for Properties A and B]
Rate the importance of Property A relative to Property B on a 9-point scale, as described above.

[How to Interpret the Calculation Results]
A higher “Overall Rating” indicates that the property better aligns with your preferences.
[About the C.I. (Consistency Index)]
The C.I. (Consistency Index) should ideally be a positive value of 0.2 or less.From “Price vs. Size” to “Seller, Construction/Management Company vs. Others,” the C.I. increases as the degree of inconsistency in the 45 pairwise comparisons grows (C.I. = 0 indicates no inconsistencies).
If the C.I. is high, review the pairwise comparisons from STEP 1.
Since there are 45 comparison points, it is quite difficult to keep the C.I. at 0.2 or lower. Therefore, if you just want a rough idea of the results, it’s acceptable to take a more lenient approach—as long as the C.I. is below 1.0.
