Like basic automatic adjustments, Appraise-It Pro's bathroom adjustments work by subtracting the comp's bath counts from the subject's bath counts and multiplying the results by the unit values you specify on the automatic adjustments addendum.
Unlike the basic automatic adjustments, in most reports the bathroom adjustments combine the adjustments for two items (the full bath count and the partial bath count) into a single adjustment value inserted in the comparables grid, because most reports do not have separate lines for full and partial baths.
When your partial bath value is not one-half of your full bath value, the combined adjustment value inserted in the grid may seem unintuitive at first glance.
Example 1
Here is a straightforward adjustment scenario:
The subject has two full baths and no half baths, and comp 1 has one of each.
Comp 1's values are subtracted from the subject, the results are multiplied by the unit values from the automatic adjustments addendum, and then totaled and inserted in the grid.
Full baths: (2 − 1) × $10,000 = $10,000
Partial baths: (0 − 1) × $5,000 = −$5,000
Total: $10,000 + −$5,000 = $5,000
Example 2
The same holds true in reverse, when the comp's counts are greater than or equal to the subject's:
The subject is unchanged from our first example, and comp 1 now has two full baths and one half bath.
Full baths: (2 − 2) × $10,000 = $0
Partial baths: (0 − 1) × $5,000 = −$5,000
Total: $0 + −$5,000 = −$5,000
Example 3
If your partial bath value is not one-half of your full bath value, the result can look off at first:
Our bath counts have reset to the first example, but our partial bath value is now $6,500 instead of $5,000.
Full baths: (2 − 1) × $10,000 = $10,000
Partial baths: (0 − 1) × $6,500 = −$6,500
Total: $10,000 + −$6,500 = $3,500
Example 4
Perhaps most confusingly, you do not get a perfectly mirrored adjustment value in this case if your comp has one more full bath than the subject rather than one less. In examples 1 and 2, the adjustment amount was $5,000 both times, the only difference being whether it was a positive or negative value. The same does not hold true here:
Full baths: (2 − 2) × $10,000 = $0
Partial baths: (0 − 1) × $6,500 = −$6,500
Total: $0 + −$6,500 = −$6,500
