Show / Hide custom php field with title

I want to display a custom field we have [using the Estatik wordpress real estate plugin] if the database field has a value and hide that if it is empty. I can get the field to display and hide if empty or filled out, but, I cannot display the text: "Year built" when the year is filled out:

<?php if( es_the_property_field('year-built1594411179f5f08c8ab6ff14') ): ?>
    <p>Year built: <?php es_the_property_field('year-built1594411179f5f08c8ab6ff14'); ?></p>
<?php endif; ?>

What can i change the code above to achieve:

If the year is filled out, I'd like it to display: Year built: 1994

If the year is left empty, i'd like the paragraph to not print at all

thanks in advance!
