I guarantee that the tax deduction did not offset the extra interest you paid and that overall, it's a net loss for you. The deduction reduces your taxable income, it does not reduce your tax directly. If you paid $30,000 in interest, it might reduce your tax by ~$10,000, so you're still down $20,000. Meanwhile, if you had half the interest rate, you might pay $15,000 in interest, reducing your tax by ~$5,000, so you're only down by $10,000. And that doesn't even get into how the standard deduction works, which you can't take if you itemize so you can take the mortgage interest deduction. I don't think there's a single scenario where choosing to spend more money than you otherwise would just for tax benefits results in a net positive.
