How many investment properties is too many?

[kiwimade64]

There was a referendum held in Berlin recently regarding the nationalisation of megaproperty holdings, which gave support to the idea that private individuals or companies should have limited numbers of residential investment properties. The local political leadership are now formulating legislation to go ahead with that proposal which will compensate landlords, nationalise their holdings, and limit future purchases.

With our current challenges around housing, should there be a limit to the number of residential properties that can be held in private hands? Or should we perhaps use taxation to persuade investors to look at more productive use of their savings?

I think limiting people to 1 rental property tax free when selling and then add capital gains tax to sale on all subsequent rentals would be enough to make an impact.
Its the property investors who hold 20 or 30 properties that are really the problem

I like this idea.  First rental, tax free.  From then on, the rate of tax increases as you purchase more properties.  The more properties, the higher the tax.
