I know a British guy who went to the States and bought a Piper Seminole. He did his multi engine instructor rating and then advertised by word of mouth for multi engine ratings. It was really cheap for the students as he only asked for a bit more than the operating cost of the aircraft. He got valuable twin time and enough to live on.
Once he had enough hours he sold the aircraft.
An excellent idea for both student and aircraft owner. I did my FAA rating soooo cheaply!
