@Brent Coombs I used the nice HELOC calculator that one of the previous posts mentioned before and ran a bunch of scenarios varying the interest rate on the HELOC and increasing it year over year to kind of stress test the model. What I found was that I could almost TRIPLE my current fixed interest rate on my mortgage, and increase that interest rate at 0.5% more each year, every year and I would still pay the same amount of interest over the life of the loan as my 30-year fixed at 3.75%. and even in that scenario, I am still paying my mortgage off in 126 months as opposed to 360.
The key to this strategy is recognizing that your personal cash-flow is a tool that can be utilized to aggressively decrease your principle balance on a daily basis and avoiding that interest. Yes your interest rate will be higher, but your balance is also a factor in the payment equation. 350K at 3.75% vs 100K at 14% is roughly the same interest payment.
It took me some time to put it all together before I had that Ah Ha moment, but the math works. and yes, there is a requirement for the owner to be disciplined with their finances. But I imagine anyone that is focused on paying their mortgage down faster is already on the right track as far as personal finance.
Your point of the marketing towards individuals that want to pay off their mortgage, but then incur more debt for investment properties is understandable. But I can see how that is a natural transition. If you are executing on this strategy and can see first hand how CASH FLOW is a very powerful tool with debt, then it makes sense that people would start to look at rental properties in the same way, because they are all about CASH FLOW.
I will definitely be pursuing this HELOC strategy for my rentals and primary residence.
