So, they can't own a home in a location they represent? I don't see that going over well. Your primary home is real estate. So is that little family cottage.
Also, congressional reps need to have a home is Washington. So, they have to rent there?
After all it is positioning real estate as investments that contribute to its unaffordability.
That said, I don't think real estate is as easily abused as stocks. Much harder to influence the value.
They could always try renting. A lot of people manage to get by doing just that.
