Within your main post loop you would add something like,
get_post_meta($post->ID, 'property_feature', true);
A basic example of what your main loop might look like ( it depends on your theme) to include a title and your custom field.
//start the loop
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
//add post link and title
<a href="https://wordpress.stackexchange.com/questions/12181/<?php the_permalink() ?>" rel="bookmark" title="Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
//add your custom meta value
<?php echo get_post_meta($post->ID, 'property_feature', true) ?>
//close loop
<?php endwhile; else: ?>
