What Is a Private Second Mortgage?

A private second mortgage is a loan secured against your home that sits behind your existing first mortgage. “Private” means the money comes from a private lender — an individual investor, a mortgage investment corporation (MIC), or a private lending company — rather than a bank. “Second” refers to the charge position: if the property is ever sold, the first mortgage is paid first, and the second mortgage lender is paid from what remains.

Because the second position carries more risk, private second mortgages have higher rates and shorter terms than bank mortgages. Terms are usually one year (sometimes two), and many are interest-only — you pay the interest monthly, and the principal comes due at the end of the term, usually refinanced or renewed at that point. Most private lenders cap your total borrowing — first plus second mortgage — at 75% to 85% of the property’s value.

Who Uses Private Second Mortgages in Ontario?

Private second mortgages exist for borrowers who can’t get what they need from a bank right now, or who need money fast:

Borrowers with bruised credit. A bank may say no after missed payments or a consumer proposal, but a private lender looks mainly at your equity. (See our guide to private mortgage lenders for bad credit in Ontario.)
Self-employed and commission earners. Banks want two years of provable income; private lenders are far less fussy about how you earn your money.
People who need money quickly. A bank refinance can take weeks. A private second can fund in days to two weeks — useful for a tax bill, a lien, or a time-sensitive purchase.
Debt consolidation. High-interest credit card debt can be replaced with a second mortgage at a much lower rate — see our guide to second mortgages for debt consolidation in Ontario.
Investors and renovators. Pulling equity for another property’s down payment or a value-adding renovation.

One thing private seconds are not: a long-term solution. They’re a bridge — funds now, while you work toward qualifying for cheaper bank financing.

How Private Second Mortgage Lenders Differ From Banks

Banks weigh credit, income, and strict qualification rules. Private second mortgage lenders simplify this to one overriding question: is there enough equity in the property to protect the loan? In practice that means credit score matters far less (many private lenders don’t even pull it), income verification is lighter (no bank-style stress test), and speed is the product — straightforward applications are often approved within 24–48 hours. The trade-off: higher rates, lender fees, and short terms.

None of this means private lenders are unregulated. In Ontario, mortgage lending is overseen by FSRA, and any broker arranging your private mortgage must hold an FSRA licence. Dealing through a licensed broker is your main consumer protection.

What Private Second Mortgage Lenders Actually Look At

Equity and loan-to-value. The big one. On an $800,000 home with a $500,000 first mortgage, you have $300,000 in equity; a lender capping combined LTV at 80% could lend up to $140,000 more. More equity means better rates and more lenders competing for your file.
Property type and condition. Lenders prefer standard residential properties in markets they know, and will usually require an appraisal.
Your exit strategy. Private seconds are short-term, so lenders want a credible answer to “how will this be repaid at the end of the term?” — refinancing into a bank mortgage, selling the property, or a known lump sum.
Ability to make the payments. The bar is lower than a bank’s, but lenders still need to see the monthly interest payments are affordable.

Rates, Fees, and the True Cost

Private second mortgages cost more than bank financing — that’s the honest headline. Expect a rate well above what a bank charges for a first mortgage, reflecting the lender’s second-position risk. Beyond the rate, budget for:

Lender fee — a percentage of the loan amount, deducted from your proceeds or added to the balance.
Broker fee — most borrowers find private lenders through a broker; in Ontario this fee must be disclosed to you in writing before you commit.
Appraisal — a full appraisal is standard, typically a few hundred dollars.
Legal fees — a real estate lawyer registers the second mortgage on title.
Renewal and discharge fees — ask upfront what the end of the term costs.

Always ask for the total cost in dollars, not just the rate: a lower rate with a large lender fee can cost more than a higher rate with no fee on a short-term loan. For a broader look at how private lending is priced, see our Ontario private mortgages page.

Red Flags to Watch For

Most private lenders operate legitimately, but the space attracts bad actors. Walk away if you see:

Upfront fees before any commitment. Fees demanded before you’ve signed a commitment letter are a classic advance-fee scam pattern. Legitimate fees are disclosed in writing and collected at funding.
No licence, no paper trail. Anyone arranging mortgages in Ontario must be FSRA-licensed. No licence number? Stop.
Guaranteed approval with no questions about the property. Real private lenders always care about the property and the equity.
Pressure to sign immediately, or verbal promises that differ from the paperwork. The commitment letter is the deal.

7 Questions to Ask Before You Choose a Lender

What is the interest rate, and is it fixed for the whole term?
What is the term length, and what are the renewal terms and fees?
What lender and broker fees apply, and when are they charged?
Are there prepayment privileges, or a penalty for paying off early?
What happens if my property value drops — can the loan be called?
Who is actually funding the mortgage — an individual, a MIC, or a company?
What is the total cost in dollars over the full term, including all fees?

The lender who answers all seven clearly and in writing is the one to work with. Vague answers are, themselves, an answer.

The Application Process

Application. Property address, estimated value, existing mortgage balance, amount needed, and purpose of funds.
Valuation. The lender orders an appraisal to confirm the value and equity position.
Commitment letter. Amount, rate, term, payment, and every fee — in writing. Have your lawyer review it.
Lawyer and funding. Your lawyer registers the second charge on title and funds are advanced, usually within days.

Straightforward files often close in one to two weeks from first call to funded.

Alternatives Worth Considering First

Refinancing your first mortgage. If your credit and income qualify, a larger bank mortgage is usually cheaper than adding a private second — though you’ll pay a prepayment penalty on the existing mortgage.
A HELOC. With strong credit and income, a bank home equity line of credit offers lower rates and flexible terms. Our guide compares home equity loans vs. HELOCs in Ontario.
A private first mortgage. If your existing first mortgage is small, refinancing everything into one private first can be simpler and cheaper than a private second behind a bank first.

Private Second Mortgage Lenders in Ontario: Quick Answers

How much can I borrow with a private second mortgage?

Most lenders allow total borrowing (first + second mortgage) of up to 75–85% of the appraised value. On an $800,000 home with a $500,000 first mortgage, that’s roughly $100,000–$180,000 in second-mortgage room.

Do I need good credit?

No. Private second mortgage lenders lend primarily against your property’s equity. Bad credit, a consumer proposal, or a past bankruptcy won’t automatically disqualify you, though they may affect the rate.

How fast can it fund?

Often approved within 24–48 hours and funded within one to two weeks, once the appraisal is done and a lawyer registers the charge.

Is a private second mortgage a good idea?

As a short-term bridge, yes — when you need funds quickly or can’t qualify at a bank yet, and you have a realistic exit strategy before the term ends. It’s expensive as a long-term solution, so plan the exit before you sign.

Are private lenders regulated in Ontario?

Yes. Mortgage lending is overseen by FSRA, and brokers arranging private mortgages must be FSRA-licensed. Always verify the licence number of anyone arranging your mortgage.

Talk to a Licensed Ontario Broker Before You Sign

A private second mortgage can solve a real problem — fast access to your equity when the banks say no. But the rates, fees, and short terms mean the details matter, and the difference between a good private deal and a bad one is usually in the fine print of the commitment letter.
