Vendor take-back mortgages: how seller financing works for buyers and sellers

A vendor take-back mortgage (VTB) is a loan from the seller to the buyer. Instead of receiving the full purchase price on closing, the seller lends part of it back and is repaid over time, with the loan secured by a mortgage registered on the property. VTBs come up most often when a buyer cannot borrow the full amount from a conventional lender, or when a seller wants to widen the pool of buyers. This post explains how they work for both sides of a residential sale. Commercial and business sales use VTBs too, but involve additional terms not covered here.

How a VTB fits into the financing

In a typical arrangement, the buyer still gets a first mortgage from a lender and makes a down payment. The VTB fills the gap and is usually registered as a second mortgage, ranking behind the first lender. Like any mortgage, it has a rate, a payment schedule and a term. FCAC describes the term as the length of time a mortgage contract is in effect; for a VTB, the term is often short, with the remaining balance due in a lump sum at the end.

What buyers should check

• The first lender's rules. Many lenders restrict or must approve secondary financing, and some will not lend if the purchase relies on a VTB. Disclose it at the application stage; hiding it can put the first mortgage at risk.
• The exit plan. A VTB often ends with a balloon payment. Know how you will repay it: savings, a refinance once you have more equity, or the sale of another property.
• Total payments. Add the VTB payment to the first mortgage, property tax and heating when you test affordability.
• Prepayment and default terms. Ask whether you can prepay without penalty and what happens if a payment is late.

What sellers should check

• Priority. As a second mortgage holder, the seller is repaid only after the first lender if the property is sold under default. A falling market can leave little equity behind the first mortgage.
• The buyer's ability to pay. Sellers are taking on lending risk without the underwriting a lender would do. Ask for the same information a lender would: income, credit and the down payment source.
• Enforcement costs. If the buyer defaults, recovering the money requires legal steps that take time and money.
• Tax timing. When the property is capital property with a taxable gain, such as a rental or a second home, receiving part of the price later can matter for tax. The Canada Revenue Agency explains in its capital gains guide that a seller who does not receive the full proceeds in the year of sale may be able to claim a reserve, which generally spreads the gain over a maximum of five years. A tax professional can confirm whether this applies.

Registration and paperwork

Our interpretation: a VTB should be documented and registered like any other mortgage, with each side ideally represented by its own lawyer or notary. The agreement of purchase and sale should spell out the VTB amount, rate, term, payment schedule and prepayment rights, so neither party is negotiating key terms after the deal is firm. Your real estate agent can help draft the offer terms, but the legal documents belong with a lawyer or notary.

Alternatives to consider

Before relying on a VTB, buyers can compare a larger down payment, a lower purchase price or a second mortgage from a private mortgage broker, keeping in mind that private financing usually costs more. Run the combined payments through the mortgage payment calculator, and talk with one of the realtors in our directory about how a VTB would be presented in an offer.
