Using has many through relationship in Laravel

Question

How can I get or display company column from contractors table to put it in my blade? I already try figured it out by using hasManyThrough relationship but it doesn't work since all example that I made reference to is not having the same flow with me.

contractors table

id 
company 

residentials table

id
contractor_id

buyers table

id
residential_id

This is the Model

Contractor.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Contractor extends Model
{
    protected $table = 'contractors';
    protected $fillable = ['user_id','company','address','phone_no','email','avatar'];

    public function residential()
    {
        return $this->hasMany(Residential::class);
    }

    public function buyers()
    {
        return $this->hasManyThrough('App\Buyer', 'App\Residential');
    }

    public function buyer()
    {
        return $this->hasOneThrough('App\Buyer', 'App\Residential');
    }
}

If I do this kind of code, it will be $contractor->buyer. While I want it to be $buyer->contractor->company

Buyer.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Buyer extends Model
{
    protected $fillable = ['buyer_id', 'name', 'address', 'phone_no', 'email', 'avatar', 'user_id', 'residential_id'];

    public function residential()
    {
        return $this->belongsTo(Residential::class);
    }
}

Residential.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Residential extends Model
{
    protected $fillable = ['name','res_code','postcode','city','state','image','contractor_id'];

    public function contractor()
    {
        return $this->belongsTo(Contractor::class);
    }

    public function buyer()
    {
        return $this->hasMany(Buyer::class);
    }
}

BuyerController.php

 public function index(Request $request)
    {
        if(Auth::user()->role == 'buyer')
            {
                $buyers = Buyer::where('user_id', '=', Auth::id())->first();
                return view('buyers.index',['buyer'=>$buyers]);
            }

This is the view that I'm working on and there is no looping since this is a profile for buyers login.

index.blade.php

<h4 class="heading"><b><center>Buyer's Details</center></b></h4>
<ul class="list-unstyled list-justify">
    <li><b>Buyer ID: </b>{{$buyer->buyer_id}}</li>
    <li><b>Name: </b>{{$buyer->name}}</li>
    <li><b>Address: </b>{{$buyer->address}}</li>
    <li><b>Residence: </b>{{$buyer->residential->name}}</li>
    <li><b>Phone Number: </b>{{$buyer->phone_no}}</li>
    <li><b>Email: </b>{{$buyer->email}}</li>
    <li><b>Contractor: </b>{{$buyer->contractor->company}}</li>
</ul>

Based on the above view code, I already did the the relationship for Residence: But I'm not able to do it for Contractor: I hope there is someone to help me.
