Brian Carwell (above) says that he used this method to dramatically pay down his primary mortgage and avoided paying large amounts of interest.
David Dachtera of Illinois (earlier parts of this thread) said he also shaved approx. 20 years from his amortization schedule, and avoided paying over $130K in interest. Is this mathematically POSSIBLE using $15K chucks from a HELOC and applying them once per year to the primary mortgage???? According to David,
"The whole point of debt acceleration, "Sweep Strategy", "Velocity Banking", or whatever you want to call it is NOT to reduce the principal paid back. It's to reduce the amount of interest you pay over the life of the loan.
For example: $200K at 5% for 30 years ...
Initially, your payments are mostly interest.
Making only the scheduled payment, that doesn't turn around until roughly the 195th payment (16-1/4 years - past the half-way point in the life of the loan). By that point, the total of payments is already in excess of the original principal balance - roughly $202K. By the end of 30 years, the interest amounts to nearly $187K, meaning it's a 93.5% loan, not 5%. Amazing what compound interest can do, eh?
By accelerating that to the tune of an additional $15K of principal per year (if you can manage it), the payoff comes closer to the 10 year mark and the total interest paid is closer to $52K or 25% of the initial loan balance. Big improvement."
So his original amortization schedule indicated $187K in interest would be paid over 30 years, but instead, he ended up paying only $52K. Where is he wrong on this calculation???
