I have DB structure:

user
    user_id
    
office
    office_id

property
    property_id
    
office_user
    office_user_id
    office_id
    user_id
    
office_user_property
    office_user_id
    property_id

Is there way to acess to Property model from User model via belongsToMany?

eloquent laravel

What you are looking for is the hasManyThrough (https://laravel.com/docs/9.x/eloquent-relationships#has-many-through), but it only work for one connection in between, and you have two.

What you could do is define a hasManyThrough relation between user and office_user_property and define a hasOne relation between office_user_property and property

belongsToMany refers to Many To Many. This relationship for your case defines that has many properties, while a property is owened by many users. In a nutshell three database tables can be used to define this relationship. properties table, users table, and user_property table. where the user_property table contains user_id and property_id columns.

In the user model, the relationship can be defined as:

/.../  
public funciton properties(){
      return $this->belonsToMany('App\Property'); 
    }

To access properties for a user:

$user = App\User::find(1);
 
foreach ($user->properties as $property) {
    //
}
