People that deduct local taxes aren't feeling the full effect of those taxes, either. Maybe they'll try to curb their bloated, greedy state and local governments if they feel the bite, instead of having the rest of us subsidize their excesses.
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
