# Assignment Sale or Resale Condo? A GTA Buyer's Due-Diligence Comparison
Quick answer: An assignment sale and a resale condo are legally and financially different purchases. In an assignment, the buyer generally acquires the original purchaser's contractual rights and obligations under a builder agreement before final closing; in a resale, the buyer purchases an already registered unit from its current owner. Assignment buyers should have the builder agreement, assignment terms, builder consent, deposits, closing adjustments, financing and tax treatment reviewed before comparing the deal with a resale condo on price alone.
2026 Tax and Due-Diligence Point Buyers Should Know
The Canada Revenue Agency states that, effective May 7, 2022, assignment sales involving newly constructed or substantially renovated residential housing are taxable for GST/HST purposes. That does not mean every buyer or seller will have the same net tax result; deposits, consideration, rebates and the facts of the original purchase can matter. For that reason, assignment tax treatment belongs with a real estate lawyer and qualified tax professional, not a rule-of-thumb calculation from a listing.
Compare the Total Transaction, Not the Headline Price
A more useful comparison is to build an all-in transaction worksheet for each option.
For an assignment, verify: original builder price; deposits already paid; assignment price or profit component; builder assignment fee; development or closing adjustments; HST treatment; occupancy-related amounts; financing availability; and the timing of interim occupancy and final closing if applicable.
For a resale condo, verify: negotiated purchase price; land transfer tax; current maintenance fee and inclusions; status-certificate findings; parking/locker ownership or use rights; and any known assessment or building work.
A lower advertised assignment price can therefore still produce a higher cash requirement at closing than a resale unit. The reverse can also be true. The comparison only becomes useful after the cash flows are placed on the same timeline.
GTA Location Lens: Toronto, Vaughan and Mississauga
Assignment activity often clusters around newer high-rise communities such as downtown Toronto, Vaughan Metropolitan Centre and parts of Mississauga. The location does not remove assignment-specific risk. Buyers should still verify the exact builder contract, project stage and consent rules for the individual agreement being assigned.
Questions That Improve an Assignment Review
- Has the builder given written consent, or what conditions must be satisfied before consent is issued?
- Which original deposits are being reimbursed to the assignor and when?
- What closing adjustments remain payable under the original agreement?
- Can my lender finance this specific structure and timing?
- What happens if occupancy or registration is delayed?
- Which HST amounts or rebates may apply to my facts?
- Are there restrictions on leasing, resale or future assignments before final closing?
What an Assignment Sale Actually Is
In an assignment sale, you're not buying a finished unit, you're buying the rights and obligations of the original agreement of purchase and sale from the assignor, stepping into their position before the building is registered and the unit exists as a legal, separate property. This is fundamentally different from a resale transaction and carries its own set of considerations.
Key Differences to Understand
| Factor | Assignment sale | Resale condo |
|---|---|---|
| What you're buying | The original purchase contract, pre-registration | A completed, registered unit |
| Builder consent | Typically required, and may involve a fee | Not applicable |
| Financing | Can be more complex; not all lenders finance assignments the same way | Standard mortgage financing |
| Tax treatment | HST treatment can differ; confirm with a tax professional | Standard resale tax treatment |
| Ability to inspect the physical unit | Often not possible before closing (pre-construction) | Full inspection possible before offer/closing |
| Closing timeline | Tied to builder's occupancy/registration schedule | Set by the parties |
Due-Diligence Questions for an Assignment Sale
- What does the builder's consent process require, and is there a fee?
- What's the realistic occupancy and registration timeline, and what happens if it's delayed?
- What financing options are actually available for this specific assignment, and have I confirmed with a lender?
- What's the tax treatment of the assignment, including HST, this needs professional confirmation, not assumption.
- What deposits has the original purchaser already paid, and how does that factor into the total price?
Due-Diligence Questions for a Resale Condo
- Have I reviewed the current status certificate?
- Have I compared recent sold data for similar units in the building?
- Have I confirmed the maintenance fee and what it includes?
Which Might Suit You
Assignment sales can offer earlier access to newer buildings and sometimes different pricing dynamics, but come with added complexity around financing, consent, and timeline uncertainty. Resale condos offer a known, inspectable product with more standard financing and closing processes. Neither is inherently better, it depends on your risk tolerance, timeline flexibility, and financing situation.
