Would put houses that the owner can't afford on the market thereby increasing supply. Adequate social security would mean they don't then get dumped on the streets.
>Eliminating the mortgage interest deduction...
Waiting changes the tax burden? No. But a capital gains tax would deincentivize flipping houses, a practice that serves little purpose other than inflating prices.
All the benefits of mortgage deduction are immediately swallowed by a commensurate increase in house price. People will always budget the same monthly payment, the only difference is whether the non-home owners (or future generation due to budget deficits) are unfairly burdened by having to make up for the missing tax revenue. The mortgage deduction is simply a funneling of money from the treasury to lending institution and provides zero long term benefit to the home owner. And Canada does not have it and their country has not fallen apart.
>Limiting realtors to hourly compensation?...
Hourly is good enough for lawyers, but salaried would also work. Seriously though, anything that does not incentive maximizing the sale price (such as pegging compensation to sale price) would reduce housing prices. Better would be tech simply replacing realtors entirely but unfortunately they have such clout in the assembly, their privileges are sacrosanct.
>I'm tempted to think you're trolling...
That is because you have never hear these ideas before exactly because they are not disseminated exactly because they would reduce housing prices which is political suicide and will cause TV views to turn the channel. I assure you not one of these ideas is my own and indeed they are well understood and discussed by very serious people eg[0], [1] and [2]
