Australia: Boycott stamp duty!
If you're a home owner, you don't have to pay stamp duty just because you change your address. If you put tenants in your former home and rent your new address, there's no change of ownership, so you pay no stamp duty, no conveyancing fees, and no commission on any sale. And you become eligible for the “negative gearing” deduction on your old address.
“But,” you ask, “won't I start paying land tax and rental management fees?” Probably; but that's all income-tax-deductible too — unlike stamp duty, conveyancing fees, and commission on the sale of a principal residence.
“But,” you ask further, “if I live away from my property for long enough, won't I have to pay capital gains tax?” Only if you actually make a capital gain! No such safeguard applies to stamp duty, conveyancing fees or agents' commissions.
Of course, if everyone adopts this strategy for avoiding stamp duty, governments will be forced to change the rules; but early adopters will save a fortune in the mean time.
