Shouldn't extra rental homes face a hefty tax?

Question:

Many homeowners seem to tap into the value of their first property to afford additional homes meant for renting, which in turn pushes prices higher and makes it tougher for newcomers to buy their first place. Would imposing a steep tax on these extra property purchases be a sound strategy? Please explain in very simple, easy-to-understand terms why this approach might be problematic.

i think extra taxes could make owners think twice about renting out extra houses, but it might also shrink the rental supply and drive some dodgy workarounds. not a magic fix
