How many investment properties is too many?

[Lilith7]

I don't think anyone would object to any couple or individual renting one or two properties, but when someone has several dozen, that's a different story altogether.
Its just unfair when a company or individual can own so many properties while others have no means of ever even owning their own house. it just goes against the grain.
It may be that we have to follow Berlin's example, at least to some extent.

If we have to put a limit on how many properties an individual, trust or company can own then we should do so carefully & make very sure that there aren't any loopholes - get our most wily lawyers to check it first perhaps.
