It's a strategy used by some debt reduction programs. It's being sold on the internet mainly. They usually take care of it for you with their software.
It's something you can do on your own though. The problem is most people are not that disciplined and with the recent credit crisis may make it not for everyone.
Here is two ways you can approach it:
approach 1: You don't need you pay check to survive. eg: want to live off whoever make the least (you or girl) salary and use the other for debt reduction.
You direct deposit go to your account then straight to the morgage. The first check can go to the mortgage for the current month that is due which will cover the principal and the interest. They next checks you have go to the principal.
The way it works is you have to have a line of credit. So if you have a line of credit that is way lower than your mortgage rate.
2nd Aproach and it gives more bang for the buck. You need a line of credit that is lower than the mortage rate.
So you pay at the begining of the month the amout of your salary on the mortgage and making sure that the additional payment over the interest goes straight to the principal (not interest buy down). Then when you get your check you pay the line of credit. And if you want to get even more slick about making your money work; when your pay check comes you take it and put it into some safe interest bearing instrument for the days before the line of credit payment is due. Then pull it out and pay the line of credit when it's due.
Also if you are going to attack your mortgage this agressively, you might as well get a 15 year mortage which usually carry a lower interest rate.
Does anyone have any info on a sort of program that allows you to direct deposit your paycheck(s) into a mortgage account...essentially paying your monthly, but allowing you to draw off the balance? And in doing so, it pays down your interest. My wife is asking me to put this up, so I'm having a tough time translating. Maybe someone has an idea here or heard of depositing directly into a mortgage account instead of a straight bank account. Any help would be appreciated.
