That is one instrument to deincentivizing accumulation of more than 1 property. Increasing supply is definitely another one but as I mentioned that earlier most of those rental units get acquired by richer landlords. One can also make those investment property mortgages much higher.

What is the point of disincentivizing the accumulation of more than one property?

To allow more people to buy property and to prevent price increases due to speculation.

Fewer landlords means cheaper to buy and more expensive to rent. Helps the upper middle class at the expense of the poor.

In my town now house prices are through the roof and the rental market is completely impacted.

So cheaper to buy would be a step up.
