[quote=AN]I don’t see why it’s not apple to apple comparison? PITI – tax deduction would be less than rent. You’re also paying ~$600/month toward principle, while rent, it’s all gone. I guess if you want to have a pure rent vs mortgage, then compare ITI – tax deduction vs rent. This particular house, ITI with 20% down is ~$1500/month. ITI with 10% down is ~$1600/month. That’s $500-600< than comparable rent. Depending on your tax bracket, you can add ~$200 to that number as well on the buying side for tax deduction.

Probably need to include transaction costs and maintenance if you're going to give yourself the benefit of realizing the principal part of the payment.
