Second Mortgage

Second mortgage: borrow against your equity without touching your first mortgage.

A second mortgage sits behind your existing first — so you keep your low locked-in rate, skip the break penalty, and still access the equity you’ve built.

You have real equity in your home, but you’re sitting on a first mortgage at a great rate you locked in years ago. Refinancing to pull that equity out would mean breaking the first — triggering a penalty that can run into the thousands — and re-pricing your whole balance at today’s rates. A second mortgage solves exactly this: it’s a separate loan registered behind your first, so your first stays untouched at its low rate, and you only pay the higher second-mortgage rate on the smaller amount you actually need. When your first comes up for renewal, we plan how to bring everything back into one mortgage.

How does a second mortgage actually sit behind my first?

A second mortgage is a separate loan registered in second position on your home’s title — your existing first mortgage stays exactly where it is, in first position. The order matters: if the property were ever sold, including under a power of sale, the first lender is paid out in full before the second lender sees a dollar. That subordinate position is the whole reason a second is priced higher than a first1 — the lender is taking the back seat on risk, so they charge for it.

What ties the two together is combined loan-to-value (CLTV): your first balance plus the new second, measured against the home’s appraised value. Alt and B-lenders generally cap CLTV around 80%; private lenders stretch to roughly 85% in strong urban markets. On a $700k home with a $400k first, 80% CLTV leaves about $160k of second-position room — and you only pay the higher second rate on that slice, never on the whole mortgage.

When does a second mortgage beat refinancing my first?

This is the core decision, and it usually comes down to one thing: the rate and penalty locked into your existing first mortgage. If you secured a low rate a few years ago, refinancing to pull equity means breaking that first — you re-price your entire balance at today’s rates (higher than many locked-in rates from a few years ago) and pay a prepayment penalty that, on a fixed mortgage, can run into five figures. You’d be paying more on a much larger balance just to access a small amount of equity.

A second mortgage sidesteps all of that. Your cheap first stays untouched at its locked-in rate, the penalty never triggers, and the higher second-mortgage rate applies only to the smaller amount you actually borrow. We model both paths side by side on every file — sometimes a clean refinance genuinely wins, but when there’s a low first or a big penalty in play, the second almost always costs less in real dollars.

What do people actually use a second mortgage for?

In our world — the complex and alternative files national generalists pass on — a second mortgage is usually a problem-solver, not a luxury. The most common use is debt consolidation: rolling high-interest credit cards, lines of credit, and loans into one secured payment at a fraction of the rate, which can free up cash flow and, with on-time payments, help rebuild credit.

Beyond that, we fund seconds for renovations, for tax and CRA arrears, and to stop enforcement — a power of sale, a foreclosure, or a judgment — before it escalates. Self-employed borrowers use them for business cash flow when a bank won’t move fast enough. And many clients use a second simply to bridge a credit-repair period: access the equity now, fix the file over twelve to twenty-four months, then graduate. The equity is the qualifier, so bruised credit and tight income are workable.

Who lends second mortgages, and what do they cost?

Two main sources fund seconds: B-lenders and private lenders (including MICs). B-lender seconds price a few points above first-mortgage rates and suit borrowers whose credit and income mostly hold up. Private seconds are equity-based — they care first about the home’s value and your position, not your beacon score — so they approve files banks decline, at a higher rate to match the risk.

Cost scales with two levers: CLTV and file quality. A 65% CLTV second on a clean property in a major market prices very differently from an 85% second on a tougher file. Private 2nd: ~9–13% + a lender fee of ~1–2% plus a broker fee of ~1–2% (typically 2–4% combined) (illustrative, Aug 2026)5. We disclose every rate, term, and fee in writing before you commit, and with access to 100+ lenders we shop the position rather than taking the first yes.

What’s the exit on a second mortgage?

A second mortgage is best treated as a bridge, not a destination. FSRA notes private mortgages are usually short-term and need a plan to exit or refinance.4 A private mortgage without an exit is a trap. We build the exit on day one. The goal is almost always the same: collapse the first and second back into a single mortgage at A-pricing once the file allows it.

The trigger is usually one of three windows. At renewal, if your combined balance is within ~80% of the home’s value and you qualify under the stress test, we can refinance the first and second into one new mortgage at a single rate. If not, we’ll plan a step-down: pay the second down, or refinance it with a B-lender first. When bruised credit has been repaired over twelve to twenty-four months, you may qualify for prime lending again. Or when arrears are cleared and income is documented, the whole picture re-prices. We set that exit date the day we fund and map the specific A-lender path to it — so you’re never paying second-mortgage rates a month longer than you have to. As an FSRA-licensed brokerage (#13737), that disclosed, planned exit is the standard, not an upsell.

How it works

Three simple steps, no pressure.

  1. 1

    Equity + purpose snapshot

    Tell us your home value, your first-mortgage balance, and what the funds are for. We calculate your available room up to 80-85% combined LTV and tell you whether a B-lender or private second fits — usually within 24 hours, no bureau pull to begin.

  2. 2

    Match the second

    B-lender second if your credit and income support it (cheaper rate, lump sum or HELOC). Private/MIC second if you need speed, flexible income, or higher LTV. We disclose the rate, term, fees, and payment in writing and pick the lowest-cost option that approves.

  3. 3

    Fund + plan the merge

    Your lawyer registers the second behind your first and the funds are advanced. We set a trigger for your first mortgage’s renewal date. At renewal, if your combined balance is within ~80% of the home’s value and you qualify under the stress test, we can refinance the first and second into one new mortgage at a single rate. If not, we’ll plan a step-down: pay the second down, or refinance it with a B-lender first.

FAQ

Common questions, answered.

What exactly is a second mortgage?
It’s a loan secured against your home that’s registered in second position — behind your existing first mortgage. If the home were ever sold, the first mortgage gets paid out first and the second is paid from what’s left. Because the second lender takes more risk being behind the first, the rate is higher — but you only pay it on the amount you borrow, not your whole mortgage.
Why not just refinance my first mortgage instead?
If your first mortgage is at a low rate or carries a steep break penalty, refinancing can be expensive — you’d re-price your entire balance at today’s rates and pay the penalty3. A second mortgage leaves your cheap first alone and layers a smaller loan on top. We always model both side by side; sometimes a refinance wins, sometimes the second does. The math decides.
Second mortgage or HELOC — what’s the difference?
A HELOC is revolving, interest-only credit, usually from an A-lender at prime-plus; it can sit behind your first mortgage, at federally regulated lenders the revolving HELOC portion is capped at 65% of your home’s value (80% combined with an amortizing mortgage)2, and requires solid credit and income to qualify. A second mortgage is broader — it can be a fixed lump sum, can come from a B-lender or private lender, and can approve when a HELOC won’t (bruised credit, self-employed, higher LTV). If you qualify for a HELOC it’s often cheaper; if you don’t, a second mortgage is the route.
How much can I borrow?
It depends on combined loan-to-value — your first mortgage plus the new second, against your home’s value. B-lenders generally cap around 80%; private lenders go to 80-85% in strong urban markets. Example: a $700k home with a $400k first allows roughly $160-195k total in second-position room depending on the lender and location.
Can I get a second mortgage with bad credit?
Yes — second mortgages are one of the most credit-flexible products out there because they’re equity-based. Private and MIC lenders care primarily about the home’s value and your equity, not your beacon score. The rate is higher to reflect the risk, but it can be a fast way to consolidate high-interest debt and, with on-time payments, help rebuild your credit.
What are second mortgage rates and fees?
B-lender seconds typically price a few points over first-mortgage rates; private/MIC seconds run higher. Private 2nd: ~9–13% + a lender fee of ~1–2% plus a broker fee of ~1–2% (typically 2–4% combined) (illustrative, Aug 2026)5. All fees are disclosed upfront. Because you’re only paying it on the smaller second amount, the dollar cost is frequently lower than refinancing the whole first.
How fast can a second mortgage close?
A private second can fund in as little as 1-2 weeks once we have an appraisal and instruct the lawyer — sometimes faster in a true emergency. B-lender seconds take a bit longer, typically 2-4 weeks. If you’re facing a deadline like tax arrears or a closing, tell us and we’ll prioritize.
Do I have to tell my first-mortgage lender?
Your first lender usually doesn’t approve the second, but some mortgage terms restrict additional borrowing, and collateral charges registered above the loan amount can complicate it. We review your charge terms before applying. The second is registered on title behind the first, so it becomes a matter of record.
What’s the exit plan?
The smart play is to treat the second as temporary. At renewal, if your combined balance is within ~80% of the home’s value and you qualify under the stress test, we can refinance the first and second into one new mortgage at a single rate. If not, we’ll plan a step-down: pay the second down, or refinance it with a B-lender first. We set that trigger date the day we fund.
Can I use a second mortgage for a down payment on another property?
Often, yes — pulling equity from your existing home via a second to fund a down payment on a rental or second property is a common strategy. Lenders on the new purchase will factor the second-mortgage payment into your qualifying, so we model the full picture across both properties before you commit.
