I'LL BET NOBODY WILL READ THIS THAT WON'T GO AWAY CHANGED BECAUSE OF IT!!!
Take a scenario in which we completely go though a real estate market cycle...you know, the ups and downs. You've got a number of rental properties financed as first lien HELOC's (no mortgage). In a booming economy you have properties cash flowing positive. You take all of the tenants payment (which consists of PITI + your cash flow) for any particular property with a HELOC and turn it against the balance of what is owed on the HELOC (pay the taxes & insurance out of the HELOC via auto pay at the appropriate times...completely automated).
What has just happened? First of all you have reduced *your monthly HELOC payment due*. Let me say that again, you have reduced your minimum payment due on the HELOC (and will continue to reduce it more and more over time). This increases your cash flow on that property and we know the only smart things to do is either keep putting your tenants check into the HELOC (to save tens of thousands on interest charges) or to acquire still other properties.
Now along comes the recession in the market and you have all the flexibility and security in the world to weather the storm. Lets count how many options you have...
1. The least amount you have to come up with to not lose your property is an interest only payment (can't do that with a mortgage and you might not be able to do a cash out refi in a down market on that mortgage either).
2. You have prepaid principal by the amount of your cash flow. You now have forced equity built up in your property and have probably saved yourself tens of thousands of dollars in interest cost compared to a 30 year amortized mortgage.This is a fact because I have seen it and done it!
3. Not only do you have the option for an interest only payment, that interest only payment has automatically decreased over time as well (your cash flow reduces your principal balance which reduces your interest payment) HELOC's recast themselves every single day.
4. If needs be, you can actually take the payment due on the HELOC, out of the HELOC and make a minimum payment back to the HELOC and satisfy that requirement (not recommended for obvious reasons). Pretty clever huh? Your objective though is to always pay MORE than the minimum. You want to work down that balance! I only mention it as a absolute last resort.
Over time you will significantly reduce the term of your debt by the amount of your cash flow going toward principal. Typically turning a 30 year term into a 5 to 10 year debt. At payoff your cash flow has maxed out and you have increased your velocity of wealth creation. But wait! there's more. LOL. Your property has also been appreciating as well as rents. You have also taken advantage of the tax laws to pay nothing in taxes.
I really don't see much risk working this strategy along with BRRRR to accelerate your path to wealth.
