Mortgage Broker or Your Bank: Who Should Arrange a Multiplex Buyer's Mortgage in BC?

No single bank or broker has the best mortgage for every 2 to 4 unit home, so compare written offers on the same day from your own bank and from a mortgage broker licensed in BC, who can show you several lenders. For an insured mortgage on a home you live in, the mortgage insurers set the rules that matter most: the price must be below $1,500,000, the minimum down payment is 5% of the first $500,000 and 10% of the rest for 1 or 2 units and 10% for 3 or 4 units (CMHC), and the insurers count up to 100% of a suite's rent in a 2 unit home and 50% in a home of 3 or 4 units. Check any broker on the public register of the BC Financial Services Authority (BCFSA), which licenses brokers under the Mortgage Services Act. Our posts on which lenders count suite rent and parents and adult children applying together go into the details.

Somewhere in the first week of shopping for a multiplex home, someone asks whether you have talked to a mortgage broker. If your only experience of borrowing is a car loan from your own bank, the question can sound strange. Why would you go to a third party for a mortgage when the bank you have used for twenty years is right there? This post answers that question for a multiplex purchase in BC, where the loan has a few details that a plain resale condo does not.

The short version: a bank specialist can offer you one lender's products. A broker can offer you many lenders' products, and is paid by whichever lender you pick. For a plain purchase with a long closing and a simple household, either route works. For a pre-sale multiplex home with a completion date that may move, or a purchase where two generations are on the mortgage, the broker route usually gives you more room. The longer version follows, along with what to ask each of them.

Who the two people are

A mortgage specialist at a bank is an employee of that bank. They know that bank's mortgages well, they can often move quickly because the approval sits inside one building, and they can tie the mortgage to the accounts you already hold. What they cannot do is offer you a competitor's product. If the bank's rules say no to your file, the answer is no, and you start again somewhere else.

A mortgage broker works for you, in the sense that they shop your application to more than one lender. In BC, brokers are regulated by the BC Financial Services Authority. Until October 12, 2026 brokers were registered under a law called the Mortgage Brokers Act. On October 13, 2026 the Mortgage Services Act and its rules came into force. Anyone who arranges mortgages for pay now needs a licence as a mortgage brokerage, principal broker or mortgage broker, or an exemption (section 3), and BCFSA must keep a public register of them (section 24). After a hearing, a licensed broker can be fined up to $250,000 and a brokerage up to $500,000 (section 45). For a buyer, the practical change is that the person arranging your mortgage holds a licence you can look up.

How each one gets paid

A bank specialist is paid a salary and, at most banks, some form of bonus tied to the mortgages they place. You never see that number, and you do not need to.

A broker is usually paid by the lender when the mortgage funds, so on an ordinary purchase you pay the broker nothing directly. Brokers may charge the borrower a fee on harder files, such as a private loan. Under the Mortgage Services Rules, which took effect on October 13, 2026, a broker must tell you in writing, before helping you, whether they act for you as a client (section 68); when they show you offers, what their brokerage will be paid, by whom, in dollars (section 72); and any interest they or a person linked to them has in the deal, at least 2 business days before you sign (section 74).

Our advice: ask both people, in plain words, "how are you paid on this file?" A good answer takes one sentence. A vague answer tells you something too.

Where a multiplex purchase gets complicated

If every multiplex purchase were a finished home, one household on title, a standard 20 percent down payment and a 60-day closing, this post would be short. Most of the multiplex purchases we see have at least one of the following features, and each one changes which route serves you better.

A pre-sale with a completion date that moves

Many brand new multiplex homes are bought pre-sale, months or a year or more before they are finished. Ask each lender how long it will hold a rate and compare that with your completion date; our rate hold guide explains how holds work on a pre-sale. A broker who does pre-sale work can ask several lenders at once. A bank specialist knows whether their own bank is one of them, and that is the end of their list.

The other thing that happens on a long timeline is that your life changes. Someone changes jobs, a baby arrives, a parent retires. A broker can move your file to a lender whose rules fit the new situation. A bank specialist can only re-run the file through the same rules.

Two generations on one mortgage

Many of our buyers are parents and adult children pooling income for one home, or buying two homes in the same building. Lenders and insurers set their own rules for a co-borrower who will not live in the home and for a guarantor: Sagen accepts a parent as a guarantor or as a second borrower who does not live in the home, and Canada Guaranty requires a guarantor to be close family. CMHC accepts a gift from a relative that you never repay. Our Buying Together guide covers the family side. On the lending side, in our view this is the clearest case for a broker, because the answer to "will this lender accept our arrangement" changes from lender to lender.

Self-employed income

If one of the buyers runs a business, lenders read the income in different ways. Our post on buying with self-employed income goes through the documents. A broker's value here is knowing how each lender reads the income before you apply.

One home in a fourplex, or the whole building

Most readers of this site are buying one home inside a multiplex, which is a strata lot with its own title. For mortgage purposes that is a one unit purchase, or two units if the home has a suite, by CMHC's way of counting a suite as a unit (ask your lender to confirm it in writing). Under CMHC's purchase rules a buyer of one or two units can borrow up to 95 percent, with a minimum down payment of 5 percent of the first $500,000 and 10 percent of the rest, as long as the price is below $1,500,000. Above that price an insured mortgage is unavailable and the minimum down payment is 20 percent.

If your family is instead buying an entire triplex or fourplex on one title, or a home with two suites by the same count, CMHC treats it as a three to four unit property with a 10 percent minimum down payment, and the insurers count 50 percent of the rent from the other units. In our view, that is a broker file from the start, because a broker can ask several lenders whether they take it.

Where the bank wins

Three situations favour walking into your own branch.

First, speed and simplicity. If you have banked in one place for years, have a large down payment, salaried income and a finished home to buy, the bank has your history already and can approve quickly. There is no lender to shop because the answer is yes.

Second, relationship pricing. Ask your bank whether it offers a lower rate to customers who also hold investments or a business account with it, and compare that offer with the broker's.

Third, a mortgage you can move. A mortgage that can be ported can be carried to your next home, and the rules differ from lender to lender. If you expect to move again within five years, read our porting guide and ask about it before you sign, whichever route you take.

Where the broker wins

Choice when the file is unusual. Pre-sale, co-borrowers, self-employed, a recent job change, a whole-building purchase: each of these narrows the list of willing lenders, and a broker starts with a longer list.

A second opinion at no direct cost. Because a broker's fee usually comes from the lender, you can have a broker look at your file while your bank works on it too. Nothing stops you from taking both offers to the table. Do tell each of them that you are doing it, and try to keep the number of full credit checks down, since every lender pulls one.

Someone whose job is your file. A bank specialist's phone rings with every customer's question. A broker's business runs on closings and referrals, and a closing that fails because the pre-sale completion moved is a broker's problem to solve.

The stress test applies either way

Whichever route you take, the federal stress test applies to mortgages at banks and other federally regulated lenders, and the maths is the same: the payment is tested at the greater of your contract rate plus 2 percent, or 5.25 percent. Our stress test post walks through it. The test is the same everywhere, but a broker can find a lender whose treatment of your income or your debts passes it when another's does not.

The Bank of Canada raised its policy rate from 2.25 percent to 2.5 percent on October 28, 2026, after holding it at 2.25 percent at every decision earlier in 2026. Its next decision is on December 9. Nothing in that changes the broker-or-bank question, but ask any lender how long a quoted rate is held, because rates can move before you sign.

What to ask before you choose

Ask a bank specialist:

• Do you offer a rate hold long enough for my completion date, and what happens if the date moves?
• Can my parents (or my adult child) be on the mortgage without living in the home?
• If my file is declined, will you tell me why in writing?
• What is the penalty if I break this mortgage in year two?

Ask a broker:

• How many lenders did you place mortgages with last year?
• How are you paid on my file, and will I see that in writing?
• Which of your lenders do pre-sale rate holds, and for how long?
• Have you closed a purchase inside a multiplex strata before?
• If the appraisal comes in below my price at completion, what is the plan?

That last question matters more in 2026 than it did two years ago. Greater Vancouver REALTORS reported for September 2026 that the townhouse benchmark fell 4.7 percent in a year and the composite benchmark fell 5.5 percent. A buyer who signed a pre-sale in 2024 may find the lender's appraisal below the contract price at completion. Our post on a low appraisal at completion covers that case.

What this comes down to

• A bank specialist sells one lender's mortgages. A broker sells many lenders' mortgages and is paid by the one you choose.
• For a finished home, a plain household and a strong file, the bank can be the fastest, so ask about a discount for your other accounts.
• For a pre-sale, a two-generation purchase, self-employed income or a whole-building purchase, a broker's longer list of lenders helps most.
• Ask both how they are paid. In BC a broker must show you what their brokerage will be paid, in writing.
• The stress test and the down payment rules are the same on both routes. What changes is which lender will say yes.
• Since October 13, 2026 BC brokers hold a licence under the Mortgage Services Act, which you can check on BCFSA's public register.

Questions buyers ask about brokers and banks

Does using a mortgage broker cost me anything?

For a standard purchase, usually no, because the lender pays the broker when the mortgage funds. A broker may charge you a fee on a harder file, such as a private loan. In BC, a broker must tell you in writing what their brokerage will be paid, and by whom, when they show you offers (Mortgage Services Rules, section 72).

Can I use a broker and my bank at the same time?

Yes. Many buyers get a quote from their bank and then have a broker try to beat it, or the other way round. Tell both of them you are doing it, so nobody wastes effort, and be aware that each lender that reviews your file will pull your credit report.

Will a broker get me a lower rate than my bank?

Sometimes. Brokers see rates from many lenders, and a bank may discount for customers who hold other accounts with it. Get both quotes on the same day and compare the whole offer, including penalties and portability.

Is a mortgage broker regulated in BC?

Yes. The BC Financial Services Authority regulates brokers. Until October 12, 2026 they were registered under the Mortgage Brokers Act. Since October 13, 2026 they are licensed under the Mortgage Services Act, and a licensed broker can be fined up to $250,000 and a brokerage up to $500,000 after a hearing.

What disclosure does a broker have to give me?

Under the Mortgage Services Rules, in writing: whether the broker acts for you as a client, before helping you (section 68); what their brokerage will be paid and by whom, in dollars, when they show you offers (section 72); and any interest they or a person linked to them has in the deal, at least 2 business days before you sign (section 74). Read each one.

Does a bank mortgage specialist need a licence?

A bank employee arranging a mortgage for their own bank works under the bank's federal regulation and the bank's own conduct rules. You can still ask them the same questions you would ask a broker, including how they are paid and what happens if your file is declined.

Which route is better for a pre-sale multiplex home?

In our view, usually a broker, because rate holds differ from lender to lender, and a broker can ask several at once. If your own bank offers a hold that covers your completion date, the bank is a fine choice.

My parents will help with the mortgage but will not live there. Who should I talk to?

In our view, a broker first. Lenders and insurers differ on co-borrowers who do not live in the home and on guarantors. A broker can tell you which lenders accept your family's arrangement before anyone applies.

Does the stress test change depending on who arranges the mortgage?

The test is set by the federal regulator and applies to federally regulated lenders, which includes every bank. The threshold is the same whoever arranges the mortgage. What differs between lenders is how they count your income and debts, which is where a broker's knowledge helps.

What if the bank turns me down?

Ask for the reason in writing, then take the file to a broker. A decline at one lender can come from that lender's own rule on one point, such as self-employed income or a co-borrower.

How do I check a broker is legitimate?

Search the BC Financial Services Authority's public register for the broker's name and their brokerage. The Mortgage Services Act requires BCFSA to keep that register of brokerages and brokers (section 24). If a name does not appear, do not proceed.

Should I choose the broker my realtor or the developer recommends?

Treat a recommendation as a starting point, and interview at least one other broker. The person selling you the home benefits when the mortgage closes, which is a reason to be sure the broker is working for you. Ask each broker how many lenders they used last year and how they are paid.

Line up the lender before you fall for a home

The buyers who have the easiest time are the ones who settle the mortgage question before they walk into a show home. Talk to your bank, talk to a broker, get both to put a pre-approval in writing, and then go shopping with a number you trust. When you are ready to see what is available, browse the multiplex homes listed on MultiLiving, or tell us what you are looking for and we will point you toward the buildings and the lenders that fit.
