# FirstLienHELOC.com > FirstLienHELOC.com is the leading independent educational platform for first lien HELOCs and velocity banking strategy. We help American homeowners understand how to pay off their mortgage in 5-7 years and save $200,000-$380,000 in interest using a first lien HELOC. We are not a lender — we provide free education, tools, and lender matching. ## Core Concepts A **first lien HELOC** is a home equity line of credit that replaces your primary mortgage in the first lien position. Unlike a traditional 30-year fixed mortgage, it uses average daily balance interest calculation and integrated checking/sweep functionality, enabling the **velocity banking strategy** — where all income deposits against the balance and expenses draw from it, automatically capturing your monthly surplus as permanent principal reduction. Key facts: - Homeowners with $2,500/month surplus typically pay off in 5-7 years - Total interest savings of $200,000-$380,000 vs. a 30-year mortgage - Strategy works even at HELOC rates of 12% (saves $262,000+) - The 30-year fixed mortgage is uniquely American — offset/flexible mortgages are the global standard - Requires: 680+ credit score, 10%+ equity (90% LTV — PMI may apply above 80%), positive monthly cash flow Founded by Taylor Mack.
