The taxable income would have been $100k less indexation in today dollars. 4% is perhaps a bit generous.
But even then it's an increase in one person's taxable income by a big amount, vs tax on two individual incomes of half a big amount. And if that's the only income either person has by that time then somebody has done a very poor job in retirement planning.
I'd be extremely surprised if the property is still negative after 15 years anyway. I'd be thinking perhaps 7 years to become neutral.
