In general, the price field is rendered by:
PHP Code:
case 'price':
$html .= ($fieldPrefix ? '<span class="prefix">' . $fieldPrefix . '</span>' : '') . '<span class="currency">' . $hotproperty->getCfg('currency') . '</span> ' . number_format($fieldValue, $hotproperty->getCfg('dec_point'), $hotproperty->getCfg('dec_string'), ($hotproperty->getCfg('thousand_sep')) ? $hotproperty->getCfg('thousand_string') : '') . ($fieldSuffix ? '<span class="suffix">' . $fieldSuffix . '</span>' : '');
break;

As you can see, there is a $fieldPrefix before the price and $fieldSuffix - after. So, check in price configs for the prefix and suffix values.
