Variable doesn't seem to be passing from controller to to view

I'm trying to pass a variable from a controller route to a view so i can display data relating to new assoicate model. It's working for other contrllers, but i can't figure out why it's not here.

Controller @Index - Not passing down

public function index(){
  $Advert = new PropertyAdvert();

  return view('pages/Advert/index', compact('Advert'));
}

@Show - Is working, this is just an example.

    public function show($id){
        $user = Auth::user();
        $Advert = PropertyAdvert::where('id', $id)->first();
        return view('pages/Advert/show', compact('Advert', 'user'));
    }

This is the route

Route::get('/property', 'AdvertisementController@index');
Route::get('/advertise', 'AdvertisementController@create')->middleware('auth');
Route::post('/createadvert', 'AdvertisementController@store');
Route::get('/property/{id}', 'AdvertisementController@show');

This is the template i'm trying to pass down to show.blade.php

<div class="row text-center" style="display:flex; flex-wrap:wrap">
        <div class="col-lg-12">
            <h3>Our most recent properties</h3>
            @foreach ($Advert as $property)
              <div class="col-md-3 col-sm-6">
                  <div class="thumbnail">
                      <img src="data:image/gif;base64,">
                      <div class="caption">
                          <h4></h4>
                      </div>
                      <p>
                          <a href="#" class="btn btn-primary">More Info!</a>
                      </p>
                  </div>
              </div>
            @endforeach
        </div>
    </div>
</div>
