Thinking about a private second mortgage in Ontario? Learn when it makes sense, how much you can borrow (borrowing room), real costs, and the exit plan—before you sign anything.
TL;DR
TL;DR: A private second mortgage in Ontario is a short-term tool that can help when banks say no—if your borrowing room (aka LTV), all-in cost, and exit plan make sense. Use it for 3–24 months, often with interest-only payments, then refinance to lower cost.
"When does a private second mortgage make sense in Ontario?"
Before deciding, get clear on the problems a private second can actually solve. These are common scenarios where the higher short-term cost can unlock a bigger financial win.
- Self-employed / limited declared income: You’re solid but can’t show two full years yet.
- Bruised / bad credit: A short bridge to stabilize, then refinance.
- CRA arrears or high-interest balances: Consolidate to stop penalties and compounding.
- Tight timelines (3–24 months): Bridge for closings, payouts, or cleanup before refi.
Basically, if the short-term cost unlocks a bigger financial win (qualify to refinance, avoid penalties, wipe high-interest debt), it can be worth it. If not, pass.
“How do I figure out my borrowing room (aka LTV) for a second mortgage?”
Your borrowing room is how much you can safely borrow based on today’s value and lender caps; lenders call this loan-to-value (LTV).
- Quick formula: (First mortgage + Target second) ÷ Current home value = % of value used.
- Typical cap: Many Ontario private second lenders cap totals near 75–85% of value.
- Stay inside the cap: Location, property type, and condition also affect the decision.
“Can you show me the math with real numbers?”
Here’s a quick example so you can sanity-check your own file. We’ll still run your exact numbers including fees, appraisal and location impact.
- Home value: $800,000
- First mortgage: $550,000
- 80% of value: $640,000 max total
- Room before fees: $640,000 − $550,000 = $90,000 (so ~$75,000 net after fees is realistic)
“What will my monthly payment look like on a private second?”
Most private seconds use interest-only payments to keep cash flow manageable during your short timeline. Exact payments depend on your approved rate, amount, and fee structure.
- Interest-only = lower monthly outlay: You’re buying time while you fix the root issue.
- Short term by design: Plan for 3–24 months, then refi out.
- We’ll show the monthly number up front—no surprises.
“What are the real costs: rates, fees, and closing expenses in Ontario?”
Don’t judge by rate alone—look at the all-in cost against the benefit you’re getting. Here’s what typically appears on second-mortgage files in Ontario.
Rate (higher than A/B): Short-term + flexible underwriting comes at a premium. Learn more about private mortgage rates.
Fees: Lender and sometimes broker fees (often % of loan).
Third-party costs: Legal, appraisal, admin, title (varies by file).
Decision rule: If all-in cost < value of the problem solved (e.g., CRA penalties, 19–29% cards, a purchase at risk), it can be worth it.
“What’s the exit plan so I don’t get stuck paying private rates?”
If we can’t see the exit, we don’t take the loan. Your roadmap should be written down on day one.
- Timeline: 3–24 months with specific review dates.
- Credit rebuild & documents: Clear collections, file taxes, normalize income on paper.
- Refinance target: Move to A or B lender as soon as ratios and credit allow.

“Do you have a quick Ontario case study?”
Real-world examples make the steps concrete. Here’s a simple one that mirrors the video.
- Profile: Self-employed, CRA arrears + card debt; home $800K, first $550K.
- Second arranged: ~$70K net after fees; interest-only payments.
- 12-month cleanup: Paid CRA, rebuilt credit, filed taxes → refinanced to lower cost.
FAQ: (Ontario-specific)
Can I get a second mortgage in Ontario with bruised credit or after a bank decline?
Yes—private lenders are equity-first, so borrowing room and exit plan matter more than perfect credit.
How much can I borrow on a private second?
Many lenders cap total borrowing around 75–85% of current value. Use the quick formula, then we’ll confirm with appraisal/fees.
Are private second mortgages always interest-only?
Often, yes—interest-only keeps monthly cost lower during your short timeline. Some lenders allow principal + interest; we can always look into this for you.
What fees should I expect at closing?
Usually lender/broker fees (percent of loan, typically 1%) plus legal, appraisal, admin/title. We quote all-in so you can compare to the benefit.
How do I get out of a private second?
Follow the exit roadmap: fix credit items, file taxes, stabilize income/ratios, then refi to A/B as soon as you qualify.
Is a HELOC better than a private second?
If you qualify, a HELOC is cheaper. If you don’t (timing/credit/doc limits), a private second can bridge you until you do.
Will this affect selling my home?
You can sell; the second is paid out on closing like any mortgage. We’ll coordinate payout statements so there are no surprises.
Takeaway - Read This Before You Sign
If a private second mortgage is on the table, keep it simple and numbers-first. Use this as your quick gut-check before moving forward.
- Short-term tool, not forever. Plan for 3–24 months, then refinance to cheaper money.
- Start with your borrowing room. Confirm today’s value and cap (often 75–85% of value total) to see what’s realistically available.
- Judge the all-in cost, not just the rate. Add rate + lender/broker fees + legal/appraisal/admin and compare to the benefit you’re getting (e.g., clearing CRA, 19–29% cards, saving a purchase).
- Cash-flow sanity matters. Interest-only payments can buy time while you fix the root issue.
- Exit plan on day one. Write the milestones (credit, taxes/docs, target ratios) and a refi date—no exit, no deal.
- Location and property condition count. They influence lender appetite and caps as much as the math.
- If the net doesn’t favour you, walk away. The right answer is sometimes “not now.”
