I agree than when calculated correctly, the "numbers don't lie".
So please: do the numbers correctly! Thank you...

If by being more effective you mean paying the mortgage sooner then that is correct but if you mean you pay less in interest then it depends on the HELOC interest rate. Short answer it is much faster to pay off a mortgage making the remainder of $2,000 after making mortgage payment than it is using a HELOC. You can pay off a mortgage making extra payment in 9 years 11 month. All the methods I show below the shortest time is 10 years 2 months when chunking a HELOC with a mortgage.
Chunking $10K @ 3.75% interest rate it would take 10 yrs 2 months to pay off a loan of $200K @ 3.75%. The mortgage would be paid off in 9 years 5 months and the HELOC 8 months later. You would end up paying $36,773 in interest payment. In an apple to apple comparison with a traditional mortgage making extra $2,000 payment a HELOC will beat it every time as long as they have the same interest rate. Also, you would pay less in interest.
Chunking $10K @ 6.475% interest rate it would take 10 years 6 months pay off a loan of $200K @3.75%. The mortgage would take 9 years 6 months and the HELOC 11 months. You would end up paying $39,278 in interest. At 2.725 (6.475%-3.75%) interest rate higher a HELOC would pay $2 more in interest than a traditional mortgage making extra payment. It would take longer to pay off the HELOC and mortgage together compared to making additional $2,000 extra payment each month.
Chunking $10K @ 9.2% interest rate it would take 10 yrs and 5 month to pay off a loan of $200K @ 3.75%. The mortgage would be paid off in 9 years 7 month and the HELOC will take 10 months. You would end up paying $41,705 in interest. At a much higher interest mortgage and HELOC would end up paying $2,433 more in interest payment and it will take longer to pay off.
When comparing apple to apple a HELOC combined with a mortgage does well against a traditional mortgage making extra monthly payment. Based on other factor the HELOC is better because of the easy access to equity even at higher interest rate. I would be willing to pay an extra $2,433 for this easy access to my equity. Psychologically it does make most people make extra monthly payment since they know this is money they can take back if they need it. In some of the comments some people said that they have their money sitting in their savings doing nothing vs. putting it to use against debt or to work hard for them. At the end of the day the question people should really be asking is are they willing to pay extra for easy access to their equity or not? If they are then a HELOC is the way to go. Otherwise, just make extra payment and put some of your money in saving. It will protect you in an emergency and at the same time pay your mortgage soonest. It is the safest thing to do.
I bet those who pay their mortgage early by making extra payment and those using a HELOC to achieve the same goal are a very small group.
