To me, this sounds like a good use-case for a custom post type for homes, but, in any case, this is the basic concept you’d need to follow to get this working as you’ve got it set up now.
<?php
// Set up the objects needed
$homes_wp_query = new WP_Query();
$all_wp_pages = $homes_wp_query->query(array('post_type' => 'page', 'posts_per_page' => '-1'));
// Get the page as an Object
$our_homes = get_page_by_title('Our Homes');
// Filter through all pages and find Our Homes' children
$home_children = get_page_children( $our_homes->ID, $all_wp_pages );
// echo what we get back from WP to the browser
echo '<pre>' . print_r( $home_children, true ) . '</pre>';
?>
That will print the post objects, then you can pick and choose which elements (like title, etc.) that you want to echo out
