get single taxonomy term from multiple selected terms

Question

I am facing a bit complex situation with my taxonomy terms. I have list of taxonomy terms.

Taxonomy (property-status):
--2018
--2019
--2020
--2021
--Coming Soon

my taxonomy have multiple terms, usually i select one term from the taxonomy to display which i use this code to get:

$status_terms = wp_get_post_terms( get_the_ID(), 'property-status');
if($status_terms) {
    foreach ( $status_terms as $term ) {
        echo $term->name;
    }
}

which is working perfect for me, but now i have selected two taxonomy terms 2019 and coming soon. If both are selected i want to show only 2019 i don't want to show coming soon alongside 2019, but if only coming soon is selected then i want to show coming soon.

You can count the terms and filter them accordingly. This might be a little bit too verbose, but may do the trick:

$status_terms = wp_get_post_terms( get_the_ID(), 'property-status');
if($status_terms) { 
    // Get the term names only
    $term_names = array_map(function($term) { return $term->name; }, $status_terms);
    if ((count($term_names) > 1) && in_array('coming-soon', $term_names)) {
        // More than one term and coming-soon. Filter it out
        foreach ( $status_terms as $term ) {
            if ($term->name != 'coming-soon') {
                echo $term->name;
            }
        }
    } else {
        // Show everything
        foreach ( $status_terms as $term ) {
            echo $term->name;
        }
    }
}   

Shorter solution:

if($status_terms) { 
  $many_terms = (count($status_terms) > 1);
  foreach ( $status_terms as $term ) {
    if ($many_terms) {
        if ($term->name != 'coming-soon') {
            echo $term->name;
        }
    } else {
        echo $term->name;
    }
  }
}
