Get post id within comments loop

Note that it might be easier to use get_comments() here, since it’s defined as:

function get_comments( $args="" ) {
    $query = new WP_Comment_Query;
    return $query->query( $args );
}

If you need the comment url, within your foreach comment loop, you can use:

$comment_url =  esc_url( get_comment_link( $comment ) );

You can also get the post id from the $comment object with:

$post_id = $comment->comment_post_ID;

then you can use that to retrieve the custom post meta:

$property_address = get_post_meta( $post_id ,'imic_property_site_address',true);

To get the corresponding post permalink

$post_url = esc_url( get_permalink( $post_id ) );
