Find .price.at-summary, and add condition. If the text of .price.at-summary  >= 13, .add x-m-price class. else if, .add r-m-price class. Or else, dont add any class.

$('.price.at-summary').each(function(){
  var text = $(this).text();
  var trimtext = $.trim(text);
  if ( trimtext.length >= 13 ) {
    $('.calculator.at-summary').addClass('x-m-price').fadeIn(400);
  }
  else if ( trimtext.length < 11 ) {
    $('.calculator.at-summary').addClass('r-m-price').fadeIn(400);
  } 
  else {
    $('.calculator.at-summary').fadeIn(400);
  }
});

  2. If expiry element exist, clone the element and add it into header.
//expiry date
var expiry = $('span.expiry_msg'); 
var expiryTop = $('#get-expired-msg');

$(function() { 
  if ($(expiry).length) { 
   $(expiry).clone().appendTo(expiryTop).addClass('expiry-on-header').fadeIn(500);
  }
});

$('.listing-summary').each(function(){
  var summaryprice = $('.price.at-summary').text();
  var trimsummaryprice = $.trim(summaryprice);
  if ( trimsummaryprice.length <= 8 ) {
    $(this).find(expiry).addClass('s-m-expired').fadeIn(400);
  }
  else if ( trimsummaryprice >= 11 ) {
    $(this).find(expiry).addClass('x-m-expired').fadeIn(400);
  }
  else {
    $(this).find(expiry).fadeIn(400);
  }
});

$(expiryTop).each(function() {

If body hasClass, change text of certain element, and change a href of specific element

if($('body').hasClass('page-node-add-forum')) {
    var crumbForumAdd3 = $('ol.breadcrumb li:nth-child(3)'),
        forumPage = '/property-forum/',
        crumbForumAdd = $('ol.breadcrumb li:nth-child(2)');

    $('h1.page-header').text( function() {
        return $(this).text().replace("Create Forum topic", "Create a Question"); 
    });

    $(crumbForumAdd3).text( function() {
        return $(this).text().replace("Create Forum topic", "Create a Question"); 
    });

    $(crumbForumAdd).html("<a href='/forum'>Forum</a>");
}
