wp query on checkboxes value

Hello
I’m trying to make a search system based on checkboxes with wp_query. I want to implement the following search:
On a custom post-type “Houses”, look for houses whose area is:
less than 50m²
from 50 to 200m²
from 200 to 1000m²
superior to 1000m²

Area values ​​come from checkbox so the user can select one or more values
I made the following request but it does not work, I tried several combinations but it does not work. I get the message “0 result” while there are houses that match the search criteria.
Here is my code:

<? Php
 $ args = array (
                           'post_type' => 'houses',
                          'posts_per_page' => -1,
                          'meta_query' => array (
                           'relation' => 'OR',
                                   array (
                                   'key' => 'wpcf-area',
                                   'value' => 50,
                                   'type' => 'numeric',
                                   'compare' => '<'
                                 ),
                                array (
                                'key' => 'wpcf-area',
                                'value' => array (50, 200),
                                'type' => 'numeric',
                               'compare' => 'BETWEEN'
                              ),
                              array (
                              'key' => 'wpcf-area',
                              'value' => array (200, 1000),
                              'type' => 'numeric',
                              'compare' => 'BETWEEN'
                               ),
                                 array (
                                   'key' => 'wpcf-area,
                                   'value' => 1000,
                                   'type' => 'numeric',
                                   'compare' => '>'
                                 )
$ query = new WP_Query ($ args);
?>

Thanks for your help
