As for rental etc. of physical products: This is straightforward, since the bundle of rights offered by the offer is defined by the gr/schema:BusinessFunction. When you rent a car, you just obtain temporary usage etc. See the definitions at

http://www.heppnetz.de/ontologies/goodrelations/v1.html#BusinessFunction

	 gr:ConstructionInstallation
	 gr:Dispose
	 gr:LeaseOut
	 gr:Maintain
	 gr:ProvideService
	 gr:Repair
	 gr:Sell
	 gr:Buy

Now I looked up ProductOrService on the Goodrelations site (http://wiki.goodrelations-vocabulary.org/Documentation/Product_or_Service) and this page mentions 3 types of Product entities specifically but doesn't mention Service.

schema:Product is equivalent to gr:ProductOrService. The reason for the naming difference is that schema:Product existed before GR was integrated.

The subtypes of schema:Product / gr:ProductOrService are for indicating more precisely whether you are talking of

- a concrete individual (e.g. a car with a VIN, a computer with a serial number, ...)
- a bag of anonymous products (a bit complicated to explain, I admit) and
- a product model, essentially a datasheet that defines properties for actualy products.

In essence, being a product is a role that a thing can take by being the object of an offer. schema:Product is not disjoint with any other type, so you can also offer a company, a place, a CreativeWork, etc.

If you need properties from another type for describing the product, then a multi-typed entity is the proper way of modeling, yes.
