1st way: To display price on home page for ads add price custom field to “All locations” and “All categories” and select “L” to make price visible on listing. Disadvantage of this option is if you have price and rent fields used to display price, and you use this option then rent will not be displayed. If this case is true for you then use second way described below.
2nd way: Use simple or gallery view for ads displayed on front page. Those will have price displayed.
There is no option displaying price like in “Simple” listing for “Full” listing. But we are thinking on ways how to add it to “Full” list view as well.
If you want to modify files then modify file in your theme folder
