Secured vs unsecured — the difference that drives everything
The whole comparison comes down to one word: collateral. A HELOC is secured by your home — the lender registers a claim against the property, so if you don't repay, your home is ultimately on the line. Because that collateral hugely reduces the lender's risk, they reward you with a much lower rate, a large limit, and flexible, interest-only terms.
A personal loan is unsecured — there's no asset backing it, so the lender's only recourse if you default is your credit and collections. To compensate for that higher risk, personal loans carry higher rates and smaller limits, sized to your income and credit rather than your home equity. Neither is 'better' in the abstract; you're trading the cost savings of putting your home up as security against the safety of keeping it out of the equation.
