Buying a brand new multiplex home before it is finished

Buying pre-sale means you sign a contract and pay a deposit for a home that is not finished yet, sometimes not started. In British Columbia, a pre-sale in a building of 5 or more strata homes comes under the Real Estate Development Marketing Act, which gives you protections that a resale purchase does not have: a document that must disclose every material fact, a window in which you can cancel for any reason at all, and a legal requirement that your deposit sits in a trust account unless the seller has insured it under a deposit protection contract and told you so. A duplex, triplex or fourplex sold as 4 or fewer strata homes is below that line, and its buyer gets 3 business days to cancel under the Property Law Act, at a cost of 0.25% of the price.

Most of the buyers we speak to have bought a home before, but never this way. The questions are always the same. How much do I have to put down, and when. What happens to that money. What if the home is late. What do I actually pay on the day I get the keys. What if I change my mind.

This guide answers those questions one at a time. Every rule, threshold and dollar figure on these pages comes from the body that issues it, with the date we checked it, so you can go and read the original yourself.

The short version

  • In a building of 5 or more strata homes, you can cancel a pre-sale purchase for any reason within 7 days, under section 21 of the Real Estate Development Marketing Act. In a duplex, triplex or fourplex sold as strata homes, section 42 of the Property Law Act gives you 3 business days, at a cost of 0.25% of the price. The 7 days run from the later of the date you signed or the date you gave written confirmation that you had a chance to read the disclosure statement.
  • In a building of 5 or more strata homes, your deposit goes into trust first. Section 18 of the same Act requires it to be held promptly by a brokerage, lawyer, notary public or other prescribed person, in a trust account at a savings institution in British Columbia. Under section 19 the seller may take it out and use it for the project only after it signs a deposit protection contract with an insurer and gives you notice.
  • Every new home built by a Licensed Residential Builder in BC carries warranty insurance: 2 years on materials and labour, 5 years on the building envelope, and 10 years on the structure, according to BC Housing.
  • A first-time buyer can now get up to $50,000 of GST back on a new home priced at or below $1 million, and a reduced amount up to $1.5 million, under the first-time home buyers' GST/HST rebate that received royal assent in March 2026.
  • Property transfer tax is fully waived on a newly built home up to $1,100,000 in value, with a partial break up to $1,150,000, if you are a Canadian citizen or permanent resident and you live in it.

What makes a pre-sale different from any other purchase

In a normal purchase you look at a finished home, you make an offer, and a few weeks later it is yours. In a pre-sale you are agreeing to buy something you cannot walk through, on a completion date that is often a year or two away and is not yet fixed. That gap is the reason the province regulates these sales separately.

In a building of 5 or more strata homes, the core document is the disclosure statement. Under section 14 of the Real Estate Development Marketing Act, the seller must file one before marketing the homes, and it must plainly disclose all material facts. Under section 15, they cannot sign a purchase agreement with you until they have given you a copy and you have confirmed in writing that you had a reasonable chance to read it. If something material changes later, section 16 requires a new statement or an amendment that clearly identifies and corrects the problem. A duplex, triplex or fourplex sold as 4 or fewer strata homes has no disclosure statement, so there the purchase agreement is the document to read.

Read that document. It is long and it is dull, and it is also the only place where the things that will annoy you in five years are written down: which parts of the building you share, what the seller is allowed to change without asking you, and what the schedule actually says.

The money, in the order you will part with it

Pre-sale money moves in stages, and the stages are far apart. The deposit comes first and is usually paid in instalments over the months after you sign. The mortgage does not start until near the end, because a lender will not fund a home that does not exist yet. The rest of the money, along with the taxes and legal fees, all lands on completion day.

One practical consequence catches people out. The mortgage rate you were quoted when you signed is not the rate you get. Your lender assesses you again close to completion, on the income and the rates in effect then, not the ones from two years earlier.

Deposit timing is set by your own contract and varies between sellers. In a building of 5 or more strata homes, the trust requirement is section 18 of the Real Estate Development Marketing Act. Section 19 lets the seller use the money instead if it has a deposit protection contract with an insurer and has given you notice.

What the province protects you from

It is worth being precise about this, because pre-sale buying gets described either as completely safe or as a gamble, and it is neither.

In a building of 5 or more strata homes, you are protected against a seller who hides a material fact, because section 22 gives you a right to damages if the disclosure statement misrepresents one. Your deposit is protected either by the trust account or, if the seller uses the money under section 19, by a deposit protection contract with an insurer. You get a cooling-off period of 7 days. In a duplex, triplex or fourplex sold as strata homes, the cooling-off period is 3 business days under the Property Law Act, at a cost of 0.25% of the price. And you get warranty insurance on the finished home, which is coverage that survives even if the company that built it disappears.

You are not protected against the market. Prices can be lower on completion day than they were when you signed, and no rule changes that. You are also not protected against your own financing falling through, which is the single most common way a pre-sale purchase goes wrong. In our view that risk is worth more attention than it usually gets, and it is the reason we tell buyers to talk to a lender before they sign, not after.

Who this way of buying suits, and who it does not

Buying pre-sale is a good fit for a household with a flexible living situation and a stable income. You get first choice of the homes in a building, which on a small multiplex matters more than it does in a tower, because there may only be four or six homes and only one of them has the yard. You also get time. The gap between the first deposit and completion is a period in which you can keep saving.

It suits families who are buying together for the same reason. Two households coordinating one purchase need lead time to sort out how they will hold title, how they will share costs, and which home each family takes. A pre-sale purchase gives them that time by design.

It is a poor fit if you have to move by a particular date, because completion dates move. It is also a poor fit if your income is likely to change, since your lender will assess you again near the end rather than relying on the approval you had at the start. If either of those describes you, look at homes that are finished or nearly finished instead. There is no penalty for buying later in the cycle, and the certainty is worth a great deal.

What to check about the people selling you the home

You can look up more than most buyers realise, and all of it is free.

Home warranty insurance in British Columbia is only available on homes built by a Licensed Residential Builder, and BC Housing maintains the licensing system behind that requirement. Ask for the licence details and the name of the warranty provider, then confirm both rather than taking a brochure at face value. Ask which specific homes the same company has already finished, and go and look at one.

Be careful with what a company says about itself. Awards, memberships and rankings on a company's own website are claims rather than confirmed facts, and the bodies that award them almost always publish their own lists. If a claim matters to your decision, check it at the source. We apply that rule to ourselves as well: everything on these pages is sourced to the body that issues it, and where a figure is set by your own contract rather than by law, we say so instead of quoting a number that sounds authoritative.

Questions buyers ask

Buying pre-sale means signing a contract and paying a deposit for a home that has not been finished yet. In British Columbia, a pre-sale in a building of 5 or more strata homes is governed by the Real Estate Development Marketing Act, which requires the seller to give you a disclosure statement covering all material facts before you sign, and gives you 7 days afterwards to cancel for any reason. A smaller building gives you 3 business days to cancel under the Property Law Act.

In a building of 5 or more strata homes, you have 7 days. Section 21 of the Real Estate Development Marketing Act lets you cancel within 7 days after the later of the date the purchase agreement was made and the date the seller obtained your written statement that you had a chance to read the disclosure statement. You need no reason, and your deposit comes back. In a duplex, triplex or fourplex sold as strata homes, section 42 of the Property Law Act gives you 3 business days, at a cost of 0.25% of the price.

In a building of 5 or more strata homes, your deposit is protected in one of two ways. Section 18 of the Real Estate Development Marketing Act requires deposits to be placed promptly with a brokerage, lawyer, notary public or other prescribed person, who holds the money as trustee in a trust account at a savings institution in British Columbia. Under section 19 the seller may use the money for the project only after it signs a deposit protection contract with an insurer and gives you notice. Ask which one applies to you.

Deposit amounts are set by each contract rather than by law, so there is no single figure we can quote you as fact. What is fixed is the structure: deposits arrive in instalments on dates written into your agreement, and every instalment is held under the same rules as the first. Ask for the full deposit schedule before you sign, not just the first payment.

Every new home built by a Licensed Residential Builder in British Columbia must carry home warranty insurance. BC Housing describes the minimum coverage as 2 years on materials and labour, 5 years on the building envelope including unintended water penetration, and 10 years on structural defects. The 2 year part has shorter sub-limits for some items, so read the certificate.

Yes. GST applies to a newly built home bought from a builder, unlike a resale home. If you are a first-time buyer, the first-time home buyers' GST/HST rebate can return up to $50,000 of it on a home priced at or below $1 million, with the rebate reduced gradually between $1 million and $1.5 million and gone at $1.5 million, according to the Canada Revenue Agency.

Often not. British Columbia's Newly Built Home Exemption removes property transfer tax entirely on a newly built home with a fair market value up to $1,100,000, with a partial exemption between $1,100,000 and $1,150,000. You must be a Canadian citizen or permanent resident, move in within 92 days, and keep it as your principal residence for the first year.

Late completion is normal on pre-sale purchases and your contract, not the law, sets what happens. Look for the outside completion date, which is the last date by which the home must be ready before you gain a right to cancel and get your deposit back. Our page on delays walks through where to find that date and what it does.

Sometimes, and only if your contract permits it. Selling the contract itself is called an assignment. In a building of 5 or more strata homes, every assignment of a purchase agreement made since 1 January 2019 must be reported to the Condo and Strata Assignment Integrity Register, and the seller normally has to consent first. Many contracts either forbid assignment or charge a fee for it.

Buying pre-sale gets you first choice of the units and time to save between the deposit and completion. Waiting for a finished home gets you certainty: you can walk through the actual rooms and you know your mortgage rate. In our view a buyer who needs to move on a fixed date, or whose income might change, is usually better off with a finished home.

Yes. You will need a lawyer or notary to complete the purchase in any case, and a pre-sale contract is worth having reviewed before your right to cancel ends: 7 days in a building of 5 or more strata homes, 3 business days in a smaller one. The disclosure statement and the purchase agreement together often run past a hundred pages, and the terms that matter most are rarely in the first ten.

Each person's eligibility is assessed individually, so a co-buyer who qualifies does not carry one who does not. The bigger practical issue with a pre-sale is timing: deposits are due long before completion, and the withdrawal rules are built around a purchase date. Confirm the sequence with your lender and your lawyer before you commit to a deposit schedule.
