Assignment Sales in Alberta: How They Work and What to Watch

An assignment sale lets someone sell a pre-construction contract before the building is even finished. It can be a smart move or a costly one — and the details matter a lot.


What an Assignment Sale Is

An assignment sale happens when the original buyer of a pre-construction property — the assignor — sells their rights and obligations under the builder's purchase contract to a new buyer, the assignee, before the property is completed and title transfers.

You're not buying the finished home from the developer. You're stepping into the shoes of someone who signed a contract with the developer years earlier. That distinction drives everything else about how these deals work.

How They Work, Step by Step

Pre-construction condos and homes in the Edmonton region are often sold years before completion. In that gap, values can move — and that's the opportunity an assignment captures.

  1. The original buyer (assignor) signs a purchase contract with the builder.
  2. Time passes and construction progresses; the property's value may rise.
  3. The assignor finds a new buyer (assignee) willing to take over the contract, often at a higher price.
  4. The builder — and often the lender — must approve the assignment. This is not automatic.
  5. The assignee pays the agreed price and assumes all remaining obligations to the builder through to completion.

The Potential Upside

  • Profit before completion. An assignor can realize appreciation without ever taking possession.
  • Access to sold-out projects. An assignee can get into a development that's no longer available directly from the builder.
  • Locked-in pricing. In a rising market, an early pre-construction price can look attractive later.

The Risks — Read These Carefully

Assignments carry risks that a normal resale doesn't:

  • The builder may not allow it, or may charge significant assignment fees. Always confirm the developer's policy in writing before you count on assigning.
  • Financing is trickier. Getting a mortgage on an assignment is often more complex than on a resale, and not every lender will do it.
  • The GST question. This is the one buyers miss. The assignment of a new or pre-construction home can carry GST consequences — on the assignment fee, on the profit, and on the underlying new-home purchase. How it's treated depends on the specifics and on intent. Do not guess here. This is a conversation for your accountant and real estate lawyer before you sign anything.
  • Market risk. If the market softens before completion, an assignor may struggle to find a buyer and can face a loss.

Best Practices

  1. Use an agent experienced with assignments and pre-construction — these are not ordinary resales.
  2. Have every contract reviewed by a real estate lawyer familiar with Alberta assignments before you commit.
  3. Confirm the builder's assignment policy and fees early, in writing.
  4. Get the tax treatment sorted up front with your accountant — especially the GST piece.

A Word on Advice

I can help you understand assignments and represent you in one, but these deals lean heavily on legal and tax specifics. The contract review belongs to your real estate lawyer, and the GST and profit-tax treatment belongs to your accountant. Those aren't corners to cut.


This is general information about assignment sales in Alberta, not legal or tax advice. For your specific deal, rely on your real estate lawyer and accountant.
