When financing is tight or a buyer doesn’t qualify for enough conventional mortgage financing, some Ontario deals are structured with a vendor take-back (VTB) mortgage — the seller effectively becomes a lender, financing part of the purchase price themselves and registering a mortgage against the property to secure it. It’s a useful tool in the right circumstances. It is not a way to reduce land transfer tax.

Because a VTB mortgage means less cash changes hands at closing, buyers sometimes assume the tax bill shrinks along with the visible cash figure. It doesn’t. Ontario land transfer tax (LTT) is calculated on the full value of the consideration for the transaction, and a vendor take-back mortgage is part of that consideration, not a discount on it.

What a Vendor Take-Back Mortgage Is

In a VTB arrangement, instead of the buyer paying the seller in full at closing (using cash plus a conventional mortgage from a bank or other lender), the seller agrees to accept a mortgage back from the buyer for part of the purchase price. The seller registers that mortgage against the property, just as a bank would, and the buyer repays it over time according to whatever terms the two sides negotiate. The seller is, in effect, financing their own buyer.

Why It Doesn’t Reduce Land Transfer Tax

Land transfer tax is calculated on the value of the consideration for the conveyance — a concept that includes cash, assumed debt or mortgages, and other non-cash consideration, not simply the amount of cash exchanged at the closing table. A VTB mortgage is consideration the seller is receiving (a promise of future payment, secured against the property) in exchange for the property. It gets included in the value of the consideration on which land transfer tax is calculated, exactly as if the buyer had paid that portion in cash.

In other words: whether a buyer pays the full price in cash, splits it between cash and a bank mortgage, or splits it between cash and a vendor take-back mortgage, the total value of the consideration — and therefore the land transfer tax owed — is generally the same. The financing structure changes who the buyer owes money to and on what terms; it doesn’t change what the government is owed in tax.

Where VTB Deals Get More Complicated

Why a Lawyer Should Structure This, Not Just Document It

A VTB mortgage is a legal instrument with real consequences beyond the tax question — priority against other financing, default and enforcement rights, discharge mechanics, and how it interacts with any conventional mortgage also being registered on the property. Getting the land transfer tax calculation right depends on getting the underlying transaction structure right in the first place, which is why VTB deals benefit from legal drafting rather than a template pulled from elsewhere.

Frequently asked questions

Does the seller pay tax on the VTB mortgage income they receive?

That’s a separate question from land transfer tax, which is paid by the buyer on the conveyance. Any tax consequences to the seller from receiving mortgage payments over time (as opposed to a lump sum at closing) are an income tax matter for the seller to discuss with a tax professional — distinct from the buyer’s land transfer tax obligation.

Can a VTB mortgage be combined with a conventional bank mortgage on the same purchase?

Yes, this is common — a buyer might use a conventional mortgage for part of the price and a vendor take-back for the remainder. Both count toward the value of the consideration for land transfer tax purposes, and the priority between the two mortgages needs to be addressed in the closing documents.

Is a vendor take-back mortgage the same as rent-to-own?

No. A VTB mortgage closes as an actual purchase, with legal title transferring to the buyer at closing and the seller holding a mortgage as security for the unpaid balance. Rent-to-own is a different structure, typically a lease combined with an option to purchase, where title doesn’t transfer until (and unless) the option is exercised later.

Who registers the VTB mortgage, and when?

The vendor take-back mortgage is registered against the property at the same time as the transfer, as part of the closing, alongside any other financing being registered. Your lawyer coordinates the registration order and priority between multiple mortgages on the same property.
