updating belongs to relationship laravel 5.2

I'd like to improve this piece of code when updating a related model (1 to 1) on laravel and also know if this is right, wrong, right but not recommended, etc. Thanks all.

    $user = User::find($id);
    $user->name = $request->input('name');
    $user->email = $request->input('email');
    $user->update();

    $tenant = Tenant::where('user_id', $id)->first();
    $tenant->suite_number = $request->input('suite_number');
    $tenant->update();
