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

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 lands strangely. 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 the particular case of a multiplex purchase in BC, where the loan has a few wrinkles 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, the provincial body that oversees mortgage brokers, real estate licensees and credit unions. Until this autumn brokers were registered under a law called the Mortgage Brokers Act. On October 13, 2026 that law is replaced by the Mortgage Services Act, which moves the industry from registration to licensing, sets out separate licence types for brokers, principal brokers, brokerages and lenders, and gives the regulator the power to fine an individual up to $250,000 and a brokerage up to $500,000 for misconduct, according to the British Columbia Law Institute's summary of the new law. For a buyer the practical change is that the person arranging your mortgage will hold a licence you can look up, with education and background checks behind it.

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 paid by the lender when the mortgage funds. Ratehub, a rate-comparison site, puts the usual range at 0.5 to 1.2 percent of the mortgage amount, paid by the lender as a finder's fee. Those are Ratehub's figures and we have not audited them, but the shape is what matters: for an ordinary, well-qualified borrower the broker's service costs you nothing directly. Brokers may charge the borrower a fee on harder files, such as a private loan, and in BC that has to be disclosed to you in writing before you commit. The BC Financial Services Authority requires brokers to give borrowers a conflict of interest disclosure statement, known as Form 10, which sets out any payment the broker receives from a lender or anyone else in the deal.

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. A lender's rate hold usually lasts 90 to 120 days, and our rate hold guide explains why that rarely covers a pre-sale timeline. Some lenders offer longer holds built for pre-sale buyers. A broker who does pre-sale work knows which lenders those are this month. 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

A large share of MultiLiving buyers are parents and adult children pooling income for one home, or buying two homes in the same building. Lenders differ on how they treat a co-borrower who will not live in the home, on how many people can be on one mortgage, and on gifted down payments. Our Buying Together guide covers the family side. On the lending side, this is the clearest case for a broker, because the answer to "will this lender accept our arrangement" varies more than most buyers expect.

Self-employed income

If one of the buyers runs a business, the way lenders read the income differs sharply between banks, credit unions and the lenders that specialise in self-employed files. Our post on buying with self-employed income goes through the documents. A broker's value here is knowing which lender will read a two-year average and which one wants three.

One home in a fourplex, or the whole building

Almost every reader of this site is buying one home inside a multiplex, which is a strata lot with its own title. For mortgage purposes that is a single-unit residential purchase, and the insured down payment rules are the familiar ones: 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, CMHC treats it as a three to four unit property with a flat 10 percent minimum down payment, and many bank branches will not touch that file at all. That is a broker file from the start.

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. Banks sometimes discount a mortgage for customers who also hold investments or a business account with them. A broker can rarely match a discount that depends on your other accounts.

Third, a mortgage you can move. Most bank mortgages can be ported, which means carried to your next home. Some lenders a broker uses have tighter rules on this. 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 for free. Because a broker's fee 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 falls apart 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. Our stress test post walks through it. A broker cannot make the test go away. What a broker can do is find a lender whose treatment of your income or your debts passes it when another's does not.

The Bank of Canada held its policy rate at 2.25 percent on September 2, 2026, where it has sat since October 2025, and the next decision is on October 28. Nothing in that changes the broker-or-bank question. It does mean the rate you are quoted today has been stable for eleven months, and the stress test threshold with it.

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 in its August 2026 statistics that the townhouse benchmark fell 4.4 percent in a year and the composite benchmark fell 5.6 percent. A buyer who signed a pre-sale in 2024 may find the lender's appraisal below the contract price at completion. We will cover that scenario on its own later this week.

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 is often fastest, and relationship discounts are real.
• For a pre-sale, a two-generation purchase, self-employed income or a whole-building purchase, a broker's longer list of lenders earns its place.
• Ask both how they are paid. In BC a broker must show you that in writing.
• The stress test and the down payment rules are the same on both routes. What changes is which lender will say yes.
• From October 13, 2026 BC brokers hold a licence under the new Mortgage Services Act, which you can check with the regulator.

Questions buyers ask about brokers and banks

Does using a mortgage broker cost me anything?

For a standard, well-qualified purchase, no. The lender pays the broker a finder's fee when the mortgage funds. A broker may charge you a fee on a harder file, such as a private or non-standard loan, and in BC that fee has to be disclosed to you in writing beforehand.

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 some lenders offer their best pricing only through brokers. Banks sometimes discount for customers who hold other accounts with them. The honest answer is to 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 are registered under the Mortgage Brokers Act. From October 13, 2026 they are licensed under the Mortgage Services Act, with new education requirements, background checks and higher penalties for misconduct.

What is the disclosure form a broker has to give me?

It is called Form 10, a conflict of interest disclosure statement. It sets out any payment the broker receives from a lender or anyone else in the transaction, and any interest the broker or a related party has in the deal. Read it. It takes two minutes.

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?

Usually a broker, because rate holds long enough for a pre-sale timeline are offered by some lenders and not others, and a broker knows which ones this month. If your own bank offers a pre-sale 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?

A broker first. Lenders differ on co-borrowers who do not occupy the home, on how many names can go on one mortgage, and on gifted down payments. 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 is often about that lender's rules on a specific 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 registry for the broker's name and their brokerage. From October 13, 2026 the registry shows licences under the new Mortgage Services Act. 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.
