No, I’m not trying to reverse the argument.
I’m trying to point out to you that your claims are vaporware.
Your arguments are unsustainable. Owners of apartment buildings are in no way obligated to lower rents based on mortgage interest deductions.
They can use that money for:
Down payments on other buildings
Taking the family on a vacation
Making improvements on another apartment building
Paying a son or daughters college tuition
...and countless other things.
Fail
At the end of the day, the only firm statement that has been made is:
Renters cannot deduct mortgage interest payments
You are making a straw man argument. Nobody said anybody was going to lower rents. The claim was that rents are lower because landlords can reduce their costs by deducting mortgage interest. In an otherwise competitive market, you charge what you think you can get, whether you have a mortgage to pay interest on, or not, and those with lower costs can undercut those with higher costs.
I don't know if you are slow or what, but I suspect you are just being deliberately obtuse so you don't have to admit that renters pay all the costs associated with the properties they rent. That's the 'fail', and it is yours. Grocery store shoppers don't get to deduct the mortgage interest payments the store's owner makes, either, but if he didn't get to, they would be the ones paying the difference.
At the end of the day, nobody is arguing against the assertion that 'Renters cannot deduct mortgage interest payments', so why do you keep saying it? Because the rest of your argument is bogus, so you have to erect a straw man argument to save face.
