Renting to the super rich - who does it?

[Ceril S.]

I ran across this little blip on zillow:

Most expensive rentals in LA

So I looked closer to home:

Most expensive rentals in Philadelphia

I know that there are huge mansions in NJ that I guess get rented to? CEO's or movie stars?

I know you'd have to have deep pockets to head down this road but I was curious if anyone here does this. Is it even profitable?

Regardless, it's fun to look at.
