There is an important difference between fetching a relationship with parentheses "$this->relationship()" or without '$this->relationship".

$this->relationship() return a query builder object where you can append conditions like where, whereHas etc. before executing the query with first(), get() etc.

$this->relationship returns the result of the query directly.

So in you're case you have to do:

return $this->Product_Category[0]->price; 

Because you want the price of the query result and not the price of a query builder object.

And because Product_Category is a collection (HasMany Relation), you have to take an item out of the collection first.
