There is a simpler and lighter solution:

First: set the slug argument for your custom post type to '/' when registering the post type:

add_action( 'init', 'register_my_post_type' );
function register_my_post_type() {
    $args = array(
            //The rest of arguments you are currently using goes here
            'rewrite'    => array(
                             'slug' => '/'
                             )
     );
     register_post_type( 'my-post-type', $args );   
}

Second: in preg_get_posts() action hook include your post type in the query when only the $query->query['name'] is present:

add_action( 'pre_get_posts', 'wpse_include_my_post_type_in_query' );
function wpse_include_my_post_type_in_query( $query ) {

     // Only noop the main query
     if ( ! $query->is_main_query() )
         return;

     // Only noop our very specific rewrite rule match
     if ( 2 != count( $query->query )
     || ! isset( $query->query['page'] ) )
          return;

      // Include my post type in the query
     if ( ! empty( $query->query['name'] ) )
          $query->set( 'post_type', array( 'post', 'page', 'my-post-type' ) );
 }

Third: I've found that in some situations there are conflicts with pages and single posts. I've been able to avoid this conflict by checking if a page with the request name exists and overriding the query conditionals but I'm not sure if more conflict can happens:

add_action( 'parse_query', 'wpse_parse_query' );
function wpse_parse_query( $wp_query ) {

    if( get_page_by_path($wp_query->query_vars['name']) ) {
        $wp_query->is_single = false;
        $wp_query->is_page = true;
    }

}

IMPORTANT: You need to flush the rewrite rules. You can do it by viviting the permalink options page in the admin area. This is needed because we are registering a new rewrite rule, so the current rewrite rules stored in the database must be regenerated.

// Well then, first use a function to mention your custom post types.

function my_custom_post_types(){
    return array(
        'os_estate', 
        'os_villas', 
        'os_chalets', 
        'os_cottages'
    );
}

// Then, filtering the request.

    add_action( 'parse_request','my_custom_post_types_parse_request', 999);

function my_custom_post_types_parse_request( $query ){

    if( isset($query->request) )
    {
        $req = explode('/', ltrim($query->request,'/'));
        if( !is_admin() && isset($req['0']) )
        {
            global $wpdb;
            $name = stripslashes($req['0']);
            $_post = $wpdb->get_row( "SELECT * FROM $wpdb->posts WHERE post_status = 'publish' AND post_name ='". $name ."' AND post_type IN ('" . join("', '", my_custom_post_types() ) . "')" );

            if( $_post )
            {
                $query->query_vars['error'] = '';
                $query->query_vars['post_type'] = $_post->post_type;
                $query->query_vars['name'] = $name;
            }
        }
    }
}

// And next filter all the desired post types link.

add_filter( 'post_type_link', 'my_custom_post_types_permalink', 10, 2);

function my_custom_post_types_permalink( $post_link, $post ){
    if( in_array( $post->post_type, my_custom_post_types() ) && !empty($post->post_name) && $post->post_status == 'publish' && '' != get_option('permalink_structure') )
    {
        $post_name = $post->post_name;
        $post_link = home_url("/$post_name/");
    }
    return $post_link;
}

EDIT: fixed errors, adding this line due to edit 6 chars minimum requirement

I think that you just need to put rewrite rule in your code in place where you register post type.

Just place this code

$rewrite = array(
    'slug'                => '',
    'with_front'          => true,
    'pages'               => true,
    'feeds'               => true,
    );

after the $labels array();

and before $args = array();
