Home Equity Loan vs. Second Mortgage: What’s the Difference?

You've probably heard both terms used interchangeably. Lenders use them loosely, and it leads to confusion. A home equity loan and a second mortgage are not the same product — they have meaningfully different structures, qualification requirements, and cost profiles. Understanding the difference prevents you from accidentally taking the wrong product for your situation.

What Is a Home Equity Loan?

A home equity loan is a lump-sum advance secured against the equity in your property. You receive all the money at once, repay it over a fixed term with a fixed interest rate, and make regular monthly payments of principal and interest.

The defining characteristics:

• Lump-sum disbursement — all funds received at closing
• Fixed interest rate — predictable payments throughout the term
• Fixed repayment schedule — same payment every month until the loan is paid off
• Secured by the property — your home is collateral

Home equity loans are often positioned as a lower-rate alternative to credit cards or personal loans. At typical rates of 8-14% for private lending, they can be significantly cheaper than unsecured borrowing at 19-24%.

What Is a Second Mortgage?

A second mortgage is a loan that sits behind the first mortgage in the lender's priority position. If you default and the property is sold, the first mortgage is paid first; the second mortgage is paid from remaining proceeds. This junior position makes second mortgages slightly higher risk for lenders — and that risk is reflected in the rate.

Second mortgages in the Canadian private lending space can be structured as:

• Closed second mortgage — Fixed term, fixed rate, regular payments. Similar structure to a home equity loan.
• Open second mortgage — Can be paid out at any time without penalty. More flexibility for the borrower.
• Collateral charge mortgage — Registered as a collateral charge on title. Often used when the intent is to eventually shift the first mortgage position.

The key difference is that second mortgages explicitly take the junior position behind the first — and the lender understands that if things go wrong, they come second. This affects how the deal is structured and priced.

Head-to-Head Comparison

When a Home Equity Loan Makes More Sense

You have good credit and want the lowest possible rate. If your credit score is above 620 and the property has clean equity, a home equity loan as a first charge (replacing or refinancing the existing first mortgage) often gets a better rate than a second mortgage position.

You have a specific, defined borrowing need. Debt consolidation, a known renovation budget, a vehicle purchase — home equity loans work well when you know exactly how much you need and when you need it.

You value payment predictability above all else. Fixed rate, fixed payment, fixed term. No surprises. You know exactly what you'll owe each month for the life of the loan.

When a Second Mortgage Makes More Sense

You don't want to disturb your existing first mortgage. If you have a solid first mortgage at a reasonable rate with no prepayment penalty, a second mortgage lets you access equity without refinancing and potentially losing that rate. Second mortgages are often used this way when the first is performing well.

You have bad credit and the first mortgage is already at a good rate. A second mortgage is the equity solution for borrowers who can't qualify for a refinance at a first-lender rate but have sufficient equity to support a private second.

You want an open term with flexible prepayment. Some second mortgages are structured as open — you can pay out without penalty at any time. This matters if you expect to sell the property within 1-2 years or expect a lump sum (bonus, inheritance, business sale) to pay it off.

The Real Cost Example

Let's say you have a home valued at $500,000 in Edmonton, with an existing first mortgage of $250,000 (50% LTV). You want to borrow $80,000 for debt consolidation.

Home equity loan (first charge, replacing first):

• New first mortgage: $330,000 at 8.5%
• Monthly payment on $80k portion: approximately $615/month
• Total interest over 5 years: approximately $12,900

Second mortgage (junior position, keeping existing first):

• Second mortgage: $80,000 at 11.5%
• Monthly payment: approximately $870/month
• Total interest over 5 years: approximately $22,200

The second mortgage is more expensive — but if your existing first is at 5.9% and you'd pay an $8,000 prepayment penalty to refinance it, the second mortgage is still the better financial decision. Context matters.

The Verdict

In most cases, a home equity loan (as a first charge or refinance) is cheaper than a second mortgage. But the choice depends on your existing first mortgage situation, your credit profile, and whether you want to disturb an already-performing first lien. Private lenders offer both products — the right broker helps you evaluate the full picture, not just the rate.
