Hi:
If you look at the data, you'll see that only 3 rows meet your subsetting IF condition. Read about the subsetting IF in the documentation. BEFORE the second INPUT statement, you have this:
if style='CONDO' or style='RANCH';

What did you think this statement was doing? Any data row that meets the criteria in the IF will go forward in the logic to the second INPUT statement. Any data row that does NOT meet the condition does NOT get parsed or get output.

Only the rows that meet the subsetting IF condition get parsed by the second INPUT statement and get OUTPUT by the implied output at the end of the DATA step program.
