... they already have those on housing. No one taxes you more or less because of how frequently you use your boat, or if you rent your boat to others, etc.

They should just make a law to decrease taxes on primary house by 75%, on secondary houses by 50%, then augment the taxation by 400%.

I understand having a vacation/family home (not in crowded cities however), but having more than one and leaving it empty just to raise the price of similar unit feel really scammy to me.

Is there a dearth of this happening? SF vacancy rates are roughly the same as they are across the country.

Also, from a balance sheet standpoint: if you raise the rent of a similar unit, then the rent lost on your empty unit goes up. You're actually losing more money (potential rent - rent received).
