A HELOC is secured by the equity in your home. Versus a normal car loan that's secured by the car. The benefits of having a HELOC in place can extend further than car loans.
Better Interest Rates
A HELOC is less risky to the lender and it often has a lower rate than a car loan.
Smaller Monthly Payments
Car loans have strict repayment terms while a HELOC requires interest-only monthly payments. Meaning that you only owe the interest due every month.
This is compared to a car loan, which has a principal and interest payment. While this is good to pay off the loan quicker, it's also a much larger monthly payment.
Flexible Financing
With a HELOC, you can pay off your car over a longer period of time than you would with a normal car loan. You can also customize the repayment schedule to fit your income.
Car loans typically have a max term of seven years. The older the car, the shorter the term. So a 10-year-old vehicle might only be eligible for a three-year term. But since a HELOC isn't secured by the car, you can stretch a HELOC out as long as you need.
Less Paperwork
When you open up a HELOC, the loan generally stays in place for up to 10 years. That means you only need to do paperwork once.
But with a car loan, vehicle title work must be done every time you buy a car. By financing with a HELOC instead, you keep the title, lien free.
Because the car doesn't have a lien on it, you can use the equity in your car to get a loan down the road if you need.
Tax Savings
Also, home mortgage interest has tax benefits that you don't get with a traditional auto loan.
