Changing the Default Sort

Adding the ?sort_id tag to the end of an IDX link will allow you to set the sort:

New or Recently Changed

?sort_id=new_or_recently_changed_first new_or_recently_changed_first
Low to High ?sort_id=price_low_to_high price_low_to_high 
High to Low ?sort_id=price_high_to_low price_high_to_low 
Status ?sort_id=status status 
City

?sort_id=city

city

Bedrooms ?sort_id=bedrooms bedrooms 
Bathrooms ?sort_id=bathrooms bathrooms

You can also choose a custom sort from the link dropdown and append the URL variable to the end of any link: ?sort_id=20160805132942535145000000x
