Vendor Take-Back Financing for a Plex: The Balance of Sale as a Seller's Lever

ImmoMulti — a direct buyer of multiplexes on the North Shore — increasingly sees owners consider vendor take-back financing (also called seller financing, or the balance of sale price) when they sell their plex or income property. The idea is simple: the seller lends part of the price to the buyer, secured by a mortgage published on the property. Well structured, this strategy can widen the buyer pool, generate interest income on the balance lent, and — most importantly — let you spread the capital gain over several years through the tax reserve. But it also carries a real risk: the security is usually second in rank, behind the buyer's bank. Here, from the owner-seller's point of view, is how to weigh the benefits against the risks.

What is a balance of sale when selling an income property?

The balance of sale is one of the ways the price is paid: the seller leaves the buyer a balance of the sale price, usually secured by a mortgage published on the property. The rest of the price is paid in cash and through a first-rank bank mortgage. It is a tool to bridge the gap between the buyer's down payment and their bank financing.

When you sell a plex, the price can be settled in several combined ways. According to Québec's real estate brokerage regulator (OACIQ), the purchase price can be covered by a deposit, an additional sum, a new mortgage loan, the assumption of an existing loan, and the balance of sale price left by the seller. This last method is what we call the vendor take-back or seller financing.

Concretely, if a buyer purchases your triplex for $700,000 but their bank finances only $560,000 and they have a $70,000 down payment, they are $70,000 short. Rather than letting the transaction fall through, you can lend them that $70,000 balance — repayable with interest on an agreed schedule, and secured by a second-rank mortgage on the property. The buyer becomes your debtor.

Why and when should a seller offer a balance of sale?

The OACIQ identifies three reasons it may be attractive for a seller to participate in financing: to widen the buyer pool, to earn a return on the balance lent, and to help close a sale that would otherwise fall through on financing. A tax benefit is added: spreading the receipt of the price allows a capital gains reserve to be claimed.

From the seller's point of view, offering financing is not a selfless favour — it is a strategic lever. Here are the main reasons.

1. Widen the buyer pool

Tighter bank criteria and higher rates have reduced the borrowing capacity of many multiplex buyers. A strong buyer who is a few points short on down payment can complete their financing thanks to your balance of price. By accepting a vendor take-back, you make your plex accessible to more qualified buyers — which supports the price and shortens the time to sell.

2. Earn interest on the balance lent

The balance you lend bears interest at a rate you freely negotiate. For the seller, this is a return on capital you would not otherwise have collected yet — often at a rate higher than a classic guaranteed investment, in exchange for the risk assumed.

3. Close a sale that would otherwise fail

Many promises to purchase collapse at the financing stage. By bridging the gap yourself, you secure the transaction and avoid putting your property back on the market.

How does a balance of sale let you spread the capital gain?

When part of the price is collectible after the year of sale, the Canada Revenue Agency allows a capital gains reserve to be deducted, deferring the taxation of a portion of the gain to the years the proceeds are actually received. For real estate, at least 20% of the gain must be brought into income each year — a maximum spread over five years (the year of sale and the following four). Revenu Québec harmonizes with this mechanism.

This is often the most powerful tax argument. Normally, you receive the full price at closing and are taxed on the entire capital gain that year. But when part of the price is collectible in later years — precisely the case with a balance of sale — the CRA generally allows a reserve to be claimed. The reserve defers taxation of the portion of the gain matching the proceeds not yet received.

There is a limit, however. For real estate, at least 20% of the gain must be brought into income each year (100% ÷ 5 years = 20%). This means the gain can be spread over a maximum of five years: the year of disposition and the following four. The reserve is calculated and reported notably on Form T2017.

The benefit of spreading the gain is twofold: you defer part of the tax and, depending on your other income, you may avoid pushing a single year into the highest tax brackets. Note, however: the reserve applies to the capital gain, not to interest. The interest you collect on the balance lent is taxable investment income, reportable each year.

What is a second-rank mortgage and what are the risks?

In Québec, priority among several mortgages is set by the order of publication in the Land Register: the mortgage published first prevails. The balance of sale is usually second in rank, behind the buyer's bank loan. On default and forced sale, the bank (1st rank) is repaid before the seller, who may be paid only partly, or not at all, if the proceeds are insufficient.

This is the heart of the risk to understand. According to Éducaloi, when a property is charged with several mortgages, the date, hour and even minute of publication in the Land Register become decisive: mortgages published first have priority over those published later. A creditor who publishes their mortgage before the others can exercise their rights first.

In a balance of sale, the buyer first obtains a first-rank bank loan to finance most of the price. Your seller's security — the mortgage protecting your balance of price — is published afterward, hence in second rank. As long as everything goes well, this has no consequence. But if the buyer defaults and the property is sold under judicial control, the order of repayment follows rank:

• The bank (1st rank) is repaid first from the sale proceeds;
• The seller (2nd rank) is repaid only from what remains, after the bank;
• If the proceeds are not enough to cover both claims, the seller may suffer a partial or total loss on their balance.

That is why the amount lent, the quality of the buyer and the real value of the property matter so much: your safety cushion is the equity that remains in the property once the bank is paid.

How can a seller stay protected with a balance of sale?

The seller reduces risk by publishing their security mortgage in the Land Register, verifying the buyer's solvency, limiting the amount lent, setting a clear rate and repayment schedule, providing default clauses, and if needed a personal guarantee. The notary verifies the creditors registered on the property before releasing the sale proceeds and oversees the drafting of the clauses.

A well-structured balance of sale considerably reduces the risk. Here are the key precautions from the seller's point of view:

• Publish the security mortgage in the Land Register to make it enforceable against third parties and set your rank.
• Vet the buyer: solvency, experience managing multiplexes, credit history, realism of their business plan.
• Limit the amount lent: the smaller your balance relative to the property's equity, the larger your cushion on default.
• Set clear terms: interest rate, term, repayment schedule, and default clauses that let you act quickly.
• Require additional security if needed: a personal guarantee from the buyer, or other collateral.

The notary plays a central role. According to Éducaloi, through their trust account the notary ensures that all of the seller's creditors with a right on the property are paid before releasing the sale proceeds. Conversely, as a second-rank creditor, you must understand that the notary will pay the priority creditor first. Always have your balance-of-sale clauses drafted and reviewed by a notary, and validate the tax structure with a tax advisor.

A balance of sale to sell a plex on the North Shore

On the North Shore (Terrebonne, Mascouche, Blainville, Boisbriand, Saint-Jérôme, Saint-Eustache), a balance of sale can help sell a plex for more or faster by widening the buyer pool. Because it is a method of paying the price, it also works in a direct sale without a broker, provided the clauses are well drafted in the notarial deed.

On the North Shore of Montréal, the multiplex market remains active, but buyers contend with higher rates and stricter bank criteria. For an owner who wants to sell their plex at a good price, offering a balance of sale can make the difference between several offers and none — especially for properties where bank financing struggles to cover the asking price.

Since the balance of sale is simply a method of payment, it fits just as well into a direct sale without a broker as into a traditional transaction. The essential point is that the terms — amount, rate, term, rank, default clauses — are clearly stipulated in the promise to purchase and the notarial deed. For a seller eager to recover their capital, you must weigh the tax benefit of spreading against the fact that part of the price will only be collected later.

Before setting the terms, also compare classic financing options and the impact on your net price.
