B-lender mortgage: when the bank says no, this is often the next step
When a bank declines your mortgage or refinance, a B-lender (alternative lender) is often the next place to look before a private loan. Here's who B-lenders help, what they look at, a worked cost example and how to plan your way back to a bank rate.
A B-lender mortgage comes from an alternative lender, a regulated lender that will look at files the big banks decline, such as newer self-employed income, bruised credit or higher debt ratios. Rates and fees are usually higher than at a bank but lower than a private mortgage, and terms are often short. FSRA describes alternative and private mortgages as a temporary option, typically for one or two years, with a realistic exit plan. In our illustration, a $400,000 B-lender mortgage at 5.79% plus a 1% fee costs about $15,700 more over two years than a 4.29% bank mortgage, which is why the exit plan matters as much as the approval.
Key takeaways
- →A B-lender is an alternative lender that looks at files banks decline: newer self-employed income, past credit problems or higher debt ratios.
- →It usually sits between a bank and a private lender on cost: a higher rate and often a lender fee, but normally well below private-mortgage pricing.
- →It's meant to be temporary. FSRA says alternative and private mortgages are typically used for one or two years until you qualify for a lower-cost option.
- →Plan the exit before you sign: what has to change (income history, credit, debt) for a bank to say yes at renewal.
- →In Ontario you need a Level 2 agent or a broker to arrange an alternative or private mortgage.
Short answer: A B-lender mortgage is a mortgage from an alternative lender: a regulated lender that will approve borrowers the big banks turn down, usually because of how income is documented, past credit problems or debt ratios that sit above bank limits. You'll typically pay a higher rate and a lender fee than at a bank, but less than with a private lender. FSRA describes alternative and private mortgages as a short-term option, typically for one or two years, until you can qualify for something cheaper [1].
This guide covers who B-lenders help, what they look at, a worked cost example and how to plan your way back to a bank rate. If you're refinancing, our mortgage refinancing page explains how we compare options across lenders.
What is a B-lender?
In the mortgage world, "A lenders" are the big banks and other lenders with standard approval rules. "B lenders" (also called alternative lenders) are regulated lenders, such as some trust companies and credit unions, with more flexible underwriting. "Private lenders" are individuals, mortgage investment corporations and private companies [1].
FSRA groups alternative and private mortgages together as options for consumers "unable to qualify for a traditional mortgage from banks and credit unions," with "higher interest rates and fees along with additional conditions or restrictions" [1]. In our experience, B-lenders still check your income, credit and the property; they're simply more willing to look at the full story than a bank's scorecard allows.
In Ontario, only a Level 2 mortgage agent or a mortgage broker can arrange a mortgage with alternative and private lenders; a Level 1 agent works with traditional lenders such as banks and credit unions [2]. 8Twelve arranges mortgages through 65+ lenders and doesn't lend or fund mortgages itself, including B-lender and private mortgages.
Who a B-lender mortgage can help
These are the situations where, in our experience, a B-lender is most often the right next step after a bank says no:
- Self-employed with a short or uneven history. Banks usually want two years of tax returns showing the income you're using. A B-lender may accept a shorter history or other proof, such as bank statements, depending on the lender.
- Bruised credit that's recovering. Past late payments, a settled collection or a recently completed consumer proposal can take you outside bank rules for a while.
- Debt ratios above bank limits. Some B-lenders allow higher gross and total debt service ratios than a bank. Our guide to GDS and TDS ratios explains how they're calculated.
- A refinance to consolidate debt when the extra debt payments are what's failing the bank's test.
- Property or timing issues, such as a unique property, a rural location or a short closing, depending on the lender.
What B-lenders look at
| Big bank (A lender) | B-lender (alternative) | Private lender | |
|---|---|---|---|
| Income proof | Strict; usually two years of documents for the self-employed | More flexible; may accept other proof, depending on the lender | Often based mainly on the property's value [1] |
| Credit | Strong recent history expected | Recent problems may be accepted with an explanation | Often less important than equity [1] |
| Stress test | Applies at federally regulated lenders [3] | Depends on who regulates the lender | Usually doesn't apply |
| Typical term | 1 to 10 years | Often 1 to 2 years | Often 1 year, frequently interest-only [1] |
| Fees | Usually none from the lender | A lender fee is common | Lender and brokerage fees are common [1] |

Does the stress test apply? OSFI requires federally regulated lenders to qualify uninsured borrowers at the greater of the contract rate plus 2% or 5.25% [3]. Some alternative lenders are federally regulated, so the stress test applies to them; others, like Ontario credit unions, are regulated provincially and follow their own regulator's lending guidance [5]. Either way, the qualifying rate is based on the higher B-lender rate, so the test can bite harder. On the $400,000 example below, the qualifying payment is about $2,999 a month at 7.79%, against about $2,629 at 6.29% for the bank offer.

What a B-lender mortgage can cost: a worked example
Illustration: you're refinancing $400,000 over a 25-year amortization. A bank would offer 4.29% if you qualified. A B-lender offers 5.79% on a two-year term, with a 1% lender fee ($4,000). These rates and the fee are assumptions for illustration, not quotes.
| Bank (if you qualified) | B-lender | |
|---|---|---|
| Rate (assumed) | 4.29% | 5.79% |
| Monthly payment | about $2,167 | about $2,510 |
| Interest over 2 years | about $33,300 | about $45,000 |
| Lender fee | $0 | $4,000 |
| Extra cost over 2 years | — | about $15,700 |
| Balance after 2 years | about $381,200 | about $384,700 |
Illustrative only, not an offer. Calculated in Python with semi-annual compounding. Legal and appraisal costs apply in both cases and aren't included.
What it shows: the B-lender route costs real money (here about $650 a month on average, including the fee) but it's a known, time-limited cost. If the alternative is staying in high-interest debt or a private mortgage, it can still be the cheaper path. If you can get to a bank in two years, the extra cost stops there.
How to get back to a bank rate: your exit plan
FSRA says you need a realistic exit strategy so you can qualify for more affordable financing when the term ends [1]. A good plan names exactly what has to change:
- Know why the bank said no. Ask your broker which rule you failed: income documents, credit, debt ratios or the property.
- Build the missing history. For self-employed borrowers, that usually means filing your next tax return on time and showing the income you need.
- Repair credit on purpose. Pay every bill on time and keep card balances well below their limits for the whole term.
- Pay down the debts that pushed your ratios over the limit, if you refinanced to consolidate.
- Avoid new debt like car loans before renewal.
- Start 4 to 6 months before maturity so your broker can shop A lenders while there's time.
When a B-lender isn't the right fit
- If a bank is still possible. A co-signer, a smaller loan or a few months' wait for a tax return can sometimes get you approved at a bank rate. Check our mortgage refinance requirements first.
- If you only need a smaller amount mid-term. A HELOC or second mortgage may avoid breaking your current mortgage [4]; our home equity takeout guide compares every option.
- If even a B-lender says no. A private mortgage may be the short-term bridge, but it costs more. Read how private mortgage rates and fees add up, and in Ontario, the private refinance fees and red flags to watch for.
- If there's no realistic exit. If nothing is likely to change in two years, talk through selling or downsizing before you take on a higher-cost loan.
From our desk: The most common B-lender file we see is a self-employed borrower whose business is doing well but whose tax returns don't show it yet. A two-year B-lender term, a plan to file the next return on time, and a reminder six months before renewal is often all it takes to get back to a bank.
A B-lender mortgage isn't a failure; it's a bridge. Know why the bank said no, compare the full cost over the term, and write down what has to change before you sign.
