Associating a 'Advert' with a 'User to User relationship'

I'm building a property app. I currently have the ability to allow users to start a tenancy with each other. Think of this as the ability to add as friends. My next challenge is to associate a specific property/advert with the tenancy. The addastenant is currently done by navigating to another users profile. Should I have this functionality on the property advert show page eg property/1. Where 1 is the property ID. When the request is sent it's user_id, tenancy_id, property_id? Would this work.

This is the table at the moment. Would it work if I added the property ID here also.

What is the ideal way to go about? I will provide the "Add as Tenant code below"

User model with methods

//The users tenancies

public function tenanciesOfMine(){
  return $this->belongsToMany('App\User', 'tenancies', 'user_id', 'tenancy_id');
}

//Inverse of user tenncies -> Both users have tenancy if one exists. One user can't be in a tenancy with someone who is not in tenacy with them.
//Like friends on FB. You can't be friends with someone, without them being friends with you also.
public function tenancyOf(){
  return $this->belongsToMany('App\User', 'tenancies', 'tenancy_id', 'user_id');
}

//If a tenancy is accepted, create the tenancy ie friendship.
public function tenancies(){
  return $this->tenanciesOfMine()->wherePivot('accepted', true)->get()->
    merge($this->tenancyOf()->wherePivot('accepted', true)->get());
}

//Request hasn't yet been accepted. Display list  of pending requests
public function tenacyRequests(){
  return $this->tenanciesOfMine()->wherePivot('accepted', false)->get();
}

//Inverse of Tenancy Requests
public function tenancyRequestsPending(){
  return $this->tenancyOf()->where('accepted', false)->get();
}

//If a user has a request pending from another user
public function hasTenancyRequestsPending(User $user){
  return (bool) $this->tenancyRequestsPending()->where('id', $user->id)->count();
}

public function hasTenancyRequestsReceived(User $user){
  return (bool) $this->tenacyRequests()->where('id', $user->id)->count();
}

//Add tenancy
public function addTenancy(User $user){
  $this->tenancyOf()->attach($user->id);
}

//Add tenancy
public function acceptTenancyRequest(User $user){
  $this->tenacyRequests()->where('id', $user->id)->first()->pivot->update([
    'accepted' => true,
  ]);
}
public function isInTenancyWith(User $user){
  return $this->tenancies()->where('id', $user->id)->count();
}

Profile page where the tenancy add method is currently user. Prehaps I could move this to the property page.

div class="row">
    <div class="col-md-6">
      <p class="text-lead">Your Landlords</p>
      @if(!$user->tenancies()->count())
        <p class="text-sub">You has no tenancies!</p>
      @else
        @foreach ($user->tenancies() as $users)
          <p>
            <span></span>
            <span class="text-muted"></span>
          </p>
        @endforeach
      @endif
    </div>
    <div class="col-md-6">
      @if (Auth::user()->hasTenancyRequestsPending($user))
        <p class="text-lead">Waiting for  to accept your request.</p>
        @elseif (Auth::user()->hasTenancyRequestsReceived($user))
          <a href="/account//accept" class="btn btn-primary">Accept Friend Request</a>
        @elseif(Auth::user()->isInTenancyWith($user))
          <p class="text-sub">You and  are friends</p>
        @elseif(Auth::user()==$user)
          @else
            <a href="/account//add" class="btn btn-primary">Start Tenancy</a>
      @endif

      <p class="text-lead">Requests from Landlords</p>
      @if(!$tenancyRequests->count())
        <p class="text-sub">You has no Tenancy Requests!</p>
        @else
          @foreach ($tenancyRequests as $Request)
            <span></span>
            <span class="text-muted"></span>
          @endforeach
      @endif
    </div>
  </div>

Controller where add and accepted are implemented

  public function getAdd($id){
    $user = User::where('id', $id)->first();

    if(!$user){
      return redirect('/')->with(['status', 'Profile Not Found']);
    }

    if(Auth::user()->id === $user->id){
        return redirect()->route('home');
    }

    if (Auth::user()->hasTenancyRequestsPending($user) ||
        $user->hasTenancyRequestsPending(Auth::user())){
          return redirect('/account/')->with('status', "Friend request already pending");
      }

    if(Auth::user()->isInTenancyWith($user)){
      return redirect('/account/')->with('status', "Already i a tenancy");
    }

    //After passing all checks. Add other account
    Auth::user()->addTenancy($user);

    return redirect('/account/')->with('status', "Request Sent");
  }

  public function getAccept($id){
    $user = User::where('id', $id)->first();

    if(!$user){
      return redirect('/')->with(['status', 'Profile Not Found']);
    }

    if(!Auth::user()->hasTenancyRequestsReceived($user)){
      return redirect('/');
    }

    Auth::user()->acceptTenancyRequest($user);

    return redirect('/account/')->with('status', "Request request accepted");


  }
