Not really, helga, you break even in the example shown above only after 35 years. If you pay $215,800 in interest that means that $900 a month out of the $2,150 monthly payment has gone to the bank's pockets and you'd pay $1,250 to rent the same house. This means that you could pay the same amount of rent for another 14-15 years using the $215,000 amount that you paid in interest. It is only then that you'd need additional money to cover the rent.

If you can't afford to pay mortgage at the very least $2,000 a month then don't get a $300,000 mortgage, get a $125,000 one!
