One of the many advantages of the home ownership accelerator that I can see is since you are never making a true mortgage payment, this is the perfect product for someone who is working a commission job.
Since you are not required to make a deposit into the checking/mortgage account for the product to continue to work its magic, you can still use the product even while making sporadic payments into the account. And since you are never actually making a mortgage payment, the pressure is off when it comes to making enough commission in any given month to actually meet all of your expenses - to include a mortgage. This not only alleviates pressure in slow months, it also preserves one's credit rating!
This is a great product for anyone working commission-structured positions, be it a realtor or even a mortgage broker !
