When you need financing for a large amount, one option that sometimes comes up is a loan secured by a property you already own (different from a mortgage to buy that same property). It's an alternative to a personal loan that offers different terms, but also a considerably higher risk if something goes wrong.
What a home equity loan is
It's a loan in which, in addition to the personal repayment commitment (as with any loan), a property already owned by the applicant (or by a third party who consents to the guarantee) is pledged as additional collateral, usually free of charges or with only partial charges. If the loan isn't repaid, the bank can foreclose on that collateral to recover the debt, just as would happen with a conventional home-purchase mortgage.
The difference in risk is the key point
With a personal loan, if you stop paying, the bank can pursue the debt in court and seize assets or income, but there's no specific asset tied to the deal from the outset. With a home equity loan, by contrast, the risk is concentrated directly on an asset identified from day one: your home (or the guarantor's). Non-payment can directly result in losing that specific property, through a foreclosure process.
Why they tend to offer better terms
Precisely because the bank reduces its risk by having real collateral of known value, home equity loans tend to offer lower interest rates and longer terms than an equivalent personal loan, while generally also allowing for higher financing amounts.
When this option can make sense
It can be reasonable for large financing needs (a full renovation, buying another property, consolidating several expensive debts into one with a better interest rate), provided there's solid, stable repayment capacity that realistically reduces the risk of future default.
Why it shouldn't be used for just any purpose
Since the risk in the event of default is notably higher than with a personal loan (losing a home, not just a partial seizure of income), it's not advisable to use this option to finance everyday consumer expenses or small financing needs, where the risk taken on is disproportionate to the benefit of a somewhat lower interest rate.
Always compare the full APR, not just the interest rate
As with any financing product, the relevant comparison between alternatives should be based on the full APR (which includes fees and associated costs), not just the advertised nominal interest rate.

Our personal loan calculator and our mortgage calculator let you compare payments and total costs for both types of financing, so you can weigh with concrete numbers whether the interest savings offset the greater risk involved.
