Displaying single item in Laravel

I am having a hard time to get over this. Try to display a a single item by ID from database. I set the controller and route, but couldn't make it. Getting error or getting no data by the changes that I make on my show.blade

This is my whole controller:

public function welcome()
    {

        $estates = array();//here

        $data['estates'] = $estates;
        return view('welcome', $data);

    }

    public function search(Request $request)
    {
        $q = $request->q;

        $estates = \DB::table('allestates')
            ->where("building_name", "LIKE", "%" . $q . "%")
            ->orWhere("address", "LIKE", "%" . $q . "%")
            ->orWhere("company_name", "LIKE", "%" . $q . "%")
            ->orWhere("region", "LIKE", "%" . $q . "%")
            ->orderBy('price')->paginate(10);

        return view("search", compact('estates', 'q'));
    }



    public function show(allestates $allestates)
    {

       $estates = allestates::where('id', $allestates->id)->first();

       return view('pages.show', ['estates' => $estates]);

    }

}

Show function must be the problem, but what is the problem I couldn't figure it out.

This is the route:

Route::get("/", "PagesController@welcome");

Route::any("/search", "PagesController@search")->name('search.route');

Route::get('pages/{id}', 'PagesController@show');

And this is the show.blade.

<tbody>
        <tr class="even">
            <td></td>
        </tr>
</tbody>

The first error is this:

Trying to get property of non-object (View: /var/www/html/laravel/resources/views/pages/show.blade.php)

After got this error I changed the show.blade to this, No error shows with this but also there is no data. So what do you think?
