First question, does your post object field allow multiple of single values. If it contains multiple then you query is close, it should be

array(
  'key' => 'place',
  'value' => '"'.$post_id.'"',
  'compare' => 'LIKE'
);

If it only contains 1 then it should be

array(
  'key' => 'place',
  'value' => $post_id
  'compare' => '='
);

The next problem is with what your returning for args

function related_homes( $args, $field, $post_id ) {
  
  // since $meta_query array does not exist yet you shouldn't use
  // $meta_query[] = 
  $meta_query = array(
    array(
      'key' => 'place',
      'value' => $post_id,
      'compare' => 'LIKE'
    )
  );
  // the correct argument key is 'meta_query'
  $args['meta_query'] = $meta_query;
  // return
  return $args;
}
