Assignment Sales in Pre-Construction, Explained
Smart Buyer Guides · ~6 min read · Updated 2026
An assignment sale is when a pre-construction buyer sells their purchase contract to another buyer before final closing. It's a legitimate strategy in some situations, but it carries specific rules, fees, and tax implications that catch buyers off guard. This is a general overview — get legal and tax advice before assigning or buying an assignment.
How assignment works
The original buyer (assignor) transfers their rights and obligations under the APS to a new buyer (assignee). The assignee pays the assignor an agreed price — typically covering deposits paid plus any negotiated premium — and takes on the remaining contract with the builder. At closing, the assignee closes directly with the builder.
Builder consent
Most APSs require the builder's written consent to an assignment. Consent typically comes with an assignment fee and conditions — including whether the assignment can be marketed publicly. Read your APS carefully for the specific terms.
The economics
| Item | Assignor (seller) | Assignee (buyer) |
|---|---|---|
| Deposits paid to date | Recouped in assignment price | Paid to assignor |
| Assignment fee to builder | Usually paid by assignor | N/A |
| Premium above deposits | Profit (potentially taxable) | Additional cost |
| Original APS obligations | Extinguished on assignment | Assumed |
| HST at closing | N/A | Handled at closing per APS |
Tax implications — read carefully
Assignment profit can be treated as income (fully taxable) rather than capital gain (partially taxable) depending on how the CRA views the intent. In addition, HST rules on assignments changed in recent years — assignment premiums are now generally subject to HST. This is a complex area; get tax advice before assigning.
Why buyers assign
Common reasons: life circumstances change (job, family, move), financing changes make closing harder, or the buyer wants to realize appreciation without holding the completed home. None of these are wrong — but plan for the cost.
Why buyers buy assignments
Assignments can offer access to a sold-out community or a specific plan that's no longer available in a new release. They can also come at prices that reflect current market conditions rather than the original launch pricing.
The Windrose picture
Any Windrose assignments would be governed by the specific APS terms and builder policies. If assignment is potentially part of your plan, raise it early — before signing — so it's not a surprise later.
Frequently asked questions

- Assignment provisions are set by the APS and may require builder consent, fees, and specific terms. Review the APS with your lawyer.

- Is buying an assignment risky?
