Pre-construction vs resale comes down to a simple trade-off: a pre-construction home is a brand-new home you buy from a builder's plans before it exists, while a resale home is an existing home you buy on MLS and can usually move into within weeks. Pre-construction gives you a staged deposit, a new-home warranty, and time to plan, but you wait years and buy on trust. Resale gives you a home you can see, inspect, and occupy now, but you take it as it is and pay the full down payment up front. Here is the full comparison so you can choose with clear eyes.
First, one distinction that trips buyers up. This guide compares brand-new pre-construction against existing resale homes listed on MLS. It is not the same as choosing between a builder's finished, ready-now inventory and a to-be-built unit. If that is your question, read our guide to move-in-ready vs pre-construction, which compares quick-closing builder homes against buying from plans.
The comparison at a glance
| Factor | Pre-Construction | Resale |
|---|---|---|
| What you buy | A new home from the builder's plans, not yet built | An existing home you can view in person |
| Move-in timeline | Years (1 to 3 for freehold, 3 to 5+ for condos) | Weeks, on a negotiated closing date |
| Condition | Brand new, never lived in | Used, condition varies by age and upkeep |
| Customization | Choose finishes, upgrades, and sometimes layout | Buy as-is, renovate after closing |
| Upfront cash | Staged deposit, often 15 to 20% over months | Full down payment at closing |
| HST/GST | Added to price; rebate for primary residence | No HST on the resale price |
| New-home warranty | Yes, mandatory Tarion warranty | No builder warranty (may have remaining coverage if newer) |
| Certainty | Buy on plans and renderings | See exactly what you get |
| Closing costs | Land transfer tax plus builder adjustments and levies | Land transfer tax, usually fewer surprise adjustments |
Price and timing work differently
The biggest difference is when you pay and when you move in. With resale, you agree on a price today and close in weeks, so the home is yours and the price is locked to current market conditions. With pre-construction, you lock a price today for a home that completes years from now, and you fund it through a deposit paid in instalments. Pre-construction deposits in the GTA typically run 15 to 20 percent of the price, spread over set dates rather than paid all at once. That staged structure is easier to save into than a full down payment, and our deposit structures guide breaks down a typical schedule.
Condition and customization
A resale home is a known quantity you can inspect; a pre-construction home is new but bought on plans. With resale, you walk the home, get a home inspection, and see the actual kitchen, roof, and windows before you commit. With pre-construction, you choose finishes and upgrades and sometimes the floor plan, and everything arrives new and under warranty, but you are buying from renderings and a model, not the finished product. Buyers who value control over finishes lean pre-construction. Buyers who want to see exactly what they are getting lean resale.
Taxes: HST is the line item buyers miss
Resale homes are not subject to HST on the purchase price, while new pre-construction homes are, with a rebate that offsets much of it for primary residences. A used home sold by an individual is an exempt supply, so you pay land transfer tax but not sales tax. A new home from a builder is taxable, and buyers typically claim the GST/HST new housing rebate when the home is their primary residence. Most GTA builder agreements are written with the rebate already assigned to the builder, so the advertised price is HST-included for owner-occupiers. If you buy to rent, the rules differ and you generally pay the HST at closing and recover it after. First-time buyers should also read our guide to the first-time home buyers GST rebate, and you can estimate your own numbers with our new home HST rebate calculator.
Warranty and protection
Every new home in Ontario carries a mandatory Tarion warranty; a resale home generally does not, unless it is new enough to have coverage left. Pre-construction buyers get deposit protection and delayed closing compensation before move-in, then 1, 2, and 7 year coverage for defects after possession. A resale buyer relies on a home inspection and the seller's disclosures instead, and takes on repairs directly. If the resale home is only a few years old, some Tarion coverage may transfer with it, so ask. For a full breakdown, see our Tarion warranty guide.
Certainty and risk
Resale gives you certainty today; pre-construction asks you to trust the plans and the builder. With resale, the home exists, the neighbourhood is established, and your closing date is short and firm. With pre-construction, closing dates can move, the finished unit can differ slightly from the renderings, and the surrounding community may still be under construction when you move in. That is why builder track record matters so much on a pre-construction deal. On a new condo you also get a 10-day cooling-off period to review everything with a lawyer, a protection resale does not include.
So which should you buy?
Choose based on your timeline, your cash flow, and how much certainty you need. Pre-construction suits buyers who are not in a rush, want a new home with a warranty and modern finishes, and prefer to fund a deposit over time. Resale suits buyers who need to move soon, want to see and inspect the exact home, and can cover a full down payment now. Neither is universally better. The right answer is the one that fits your situation, and that is the conversation we have with every buyer before they commit either way.

Frequently Asked Questions
Is it better to buy pre-construction or resale?
Neither is universally better. Pre-construction suits buyers who can wait years, want a new home with a warranty and chosen finishes, and prefer a staged deposit. Resale suits buyers who need to move soon, want to inspect the exact home, and can pay a full down payment now. The right choice depends on your timeline, cash flow, and how much certainty you need.
Do you pay HST on a resale home in Ontario?
No. A used home sold by an individual is an exempt supply, so there is no HST on the resale purchase price. You still pay land transfer tax and legal fees. New pre-construction homes from a builder are taxable, but most primary-residence buyers claim the GST/HST new housing rebate, which builders often assign into an HST-included price.
How is a pre-construction deposit different from a resale down payment?
A pre-construction deposit is typically 15 to 20 percent of the price, paid in instalments over months while the home is built, and held in trust. A resale down payment is paid in full at closing, usually within weeks of the offer. The staged pre-construction structure is often easier to save into, but the total commitment is similar.
Does a resale home come with a warranty?
Generally no. A resale home does not include a builder warranty unless it is new enough to still be inside its Tarion coverage window, in which case remaining coverage can transfer to you. Otherwise, resale buyers rely on a home inspection and seller disclosures. Every new pre-construction home, by contrast, carries a mandatory Tarion warranty.
Is pre-construction riskier than resale?
It carries different risk. Pre-construction closing dates can move, the finished home can differ slightly from the renderings, and you buy before the home exists, so builder track record matters. Resale gives you a home you can see and inspect today. New condos do include a 10-day cooling-off period to review the deal with a lawyer, which resale does not.
What is the difference between pre-construction and move-in-ready homes?
Pre-construction means buying from a builder's plans before the home is built, with a move-in years away. Move-in-ready (or quick-closing) homes are builder inventory that is finished or nearly finished, so you can close in weeks. Both are new homes with a Tarion warranty. Our move-in-ready vs pre-construction guide compares those two directly.
