What is the HELOC mortgage payoff strategy?
The strategy uses a HELOC as a "checking account on steroids." Step 1: open a HELOC. Step 2: pull a large draw and apply it as a lump sum to your mortgage principal. Step 3: deposit your paychecks into the HELOC. Step 4: pay all expenses from the HELOC. Step 5: as cash builds, make another lump-sum mortgage payment. Repeat.
Why do advocates believe it works faster?
HELOCs charge interest on the average daily balance. If your paycheck sits in the HELOC for 28 days before bills consume it, that 28 days of "free" cash reduces HELOC interest. Advocates claim this drives down total mortgage payoff time dramatically.
What does the honest math actually show?
Side-by-side comparisons of HELOC strategy vs. simple monthly extra principal payments routinely show nearly identical total interest savings — within 1-3% of each other. The HELOC adds complexity and risk for marginal benefit.
What are the real risks of the HELOC strategy?
- Variable rates. HELOC rates float with the prime rate. A 2-3% rate spike can erase projected savings.
- Credit line freezes. Lenders can reduce or freeze HELOCs in downturns.
- Second lien. A HELOC creates a second lien on your home.
- Discipline failure. If you fail to live below your means, the HELOC balance grows instead of the mortgage shrinking.
- Course-seller hype. "Velocity banking" courses charge $1,500-$5,000 for what is fundamentally a basic spreadsheet exercise.
Who should actually consider the HELOC strategy?
Only a narrow profile: high-income earners with bulletproof cash flow, excellent budgeting discipline, fully funded emergency reserves, and low risk of job disruption. For everyone else, simple monthly extra principal payments deliver 95%+ of the savings with none of the risk.
