With respect to the qualification it is a fairly loose interpretation as the 750 hours. Is the time you are on piggington considered research.
Probably. That would be an easy way to rack up the 750 hours.
The other problem is that RE has to be your primary line of work.
So, I think people who do not otherwise have full-time positions (or those who work in cash jobs) could more easily find a way to justify to be classified as a RE professional. The other loophole is that if you are married, just one of you has to be a RE professional. Most people who are full-time W-2 employees in other lines of work would be excluded.
