Buying

Can't Close on Pre-Construction? Your Options in Ontario

5 min readPublished

By Summitly Editorial

Quick answer

If you may not be able to close on a pre-construction home, act early. Your main options are to find other financing, ask the builder for an extension or other relief, sell by assignment before closing, or negotiate a release. Not closing is a default: you can lose your deposits and be sued for the builder's losses. Speak to a real estate lawyer as soon as you see the risk.

Key facts: what to do when you can't close on a pre-construction home

Why pre-construction closings fail

A pre-construction agreement fixes the price years before closing. By the time the building is ready, a lot can change. The lender will lend on the home's appraised value at closing, so if values have fallen, there can be a gap between your price and the mortgage you can get. Interest rates may be higher, your income may have changed, and you must pass the mortgage stress test again at closing.

The stress test uses the higher of 5.25% or your contract rate plus 2 percentage points. On top of the down payment, closing adjustments and land transfer tax add to the cash you need on the day.

A timeline to follow if closing looks difficult

  • As soon as the occupancy or closing date is firm: get a fresh mortgage pre-approval and a lawyer's review of the agreement
  • Months before closing: estimate the appraisal gap using recent sales of similar units, and total your closing costs
  • If there is a gap: talk to a mortgage professional about other lenders and to your lawyer about the builder
  • If an assignment is possible: list it early enough to allow for the builder's consent
  • Weeks before closing: confirm your funds, your mortgage commitment and your lawyer's instructions

Option 1: find other financing

  • Ask a mortgage professional to shop other lenders, including credit unions and lenders with different appraisal and income rules
  • Increase the down payment from savings, an FHSA, the RRSP Home Buyers' Plan (if eligible) or a family gift
  • Add a co-borrower or guarantor, understanding that they take on real liability
  • Short-term or private financing is sometimes used to close; it is expensive and should come with a clear plan to refinance or sell

Option 2: talk to the builder early

Builders would usually rather close a sale than chase a default. Some have offered extensions, moves to a smaller or cheaper unit, credits, or help with financing on some projects. Nothing obliges a builder to offer any of these, and any change must be written into an amendment to your agreement. Approach the builder through your lawyer, well before the closing date, with a clear proposal.

Option 3: sell by assignment before closing

If the agreement allows it and the builder consents, you can assign the agreement to a buyer who closes in your place. You get your deposits back (and any profit) from the buyer, or accept less if the market has fallen, which can still cost less than a default. Start early: finding a buyer, the builder's consent and the lawyers' work all take time, and some agreements block assignments close to closing.

Check whether assigning releases you. Many agreements keep the original buyer liable if the assignee fails to close.

Option 4: negotiate a release, or close and then lease or sell

Some buyers negotiate a mutual release, where the builder cancels the agreement in exchange for keeping some or all of the deposit. It ends the risk of a larger claim, but it usually costs money and requires the builder's agreement.

If you can close but cannot carry the home alone, leasing it after closing can help with the monthly costs. Check your mortgage terms and, for condos, the declaration and rules. During interim occupancy, before registration, many agreements restrict leasing without the builder's consent. Selling after closing is also possible, but you must close first, and selling quickly can trigger tax.

What happens if you do not close

  • Not closing on the date in your agreement is a default, and the builder can terminate the agreement
  • The agreement usually lets the builder keep your deposits
  • The builder can resell the home and sue you for any shortfall between your price and the resale price, plus its costs
  • Tarion's deposit protection does not apply when the buyer is the one who defaults
  • A court judgment can affect your credit and your other assets
  • Payments for upgrades and extras are usually lost along with the deposits, depending on the agreement
  • If you believe the builder breached the agreement or its disclosure obligations, your lawyer may see rights to rescind; do not assume so without advice

If the debt is overwhelming

If a default claim would be more than you can pay, a Licensed Insolvency Trustee can explain formal options such as a consumer proposal. Get that advice before you sign any settlement, so you understand how each choice affects you.

Key takeaways: what to do when you can't close on a pre-construction home

  1. Act months before closing, not weeks: every option takes time.
  2. Shop other lenders and sources of down payment first.
  3. Ask the builder, through your lawyer, for an extension or other relief in writing.
  4. An assignment can limit a loss, if the agreement allows it; check whether it releases you.
  5. Not closing usually means losing deposits and facing a claim for the builder's losses.

What to do when you can't close on a pre-construction home: frequently asked questions

What happens if I can't close on a pre-construction condo in Ontario?

It is a default under your agreement. The builder can usually keep your deposits, resell the unit and sue you for any shortfall and its costs. Talk to a lawyer early about financing, an extension, an assignment or a negotiated release.

Can the builder sue me if I don't close?

Yes. If the builder resells the home for less than your price, it can claim the difference plus its costs, on top of keeping your deposits, depending on the agreement.

Can I rent out my new condo during interim occupancy to help carry it?

Check your agreement first. Many agreements restrict leasing during interim occupancy, before the condominium is registered, unless the builder consents. After final closing, leasing is possible subject to your mortgage terms and the condo's declaration and rules.

What if the appraisal comes in below my purchase price?

The lender lends on the appraised value, so you must cover the gap with more down payment or other financing. Ask a mortgage professional to try other lenders and to challenge the appraisal if there is evidence it is low.

Can I assign my unit if I can't close?

If your agreement allows assignment and the builder consents, yes. Start early, because finding a buyer and getting consent take time, and check whether the assignment releases you from liability.

Can I get an extension on my pre-construction closing date?

Only if the builder agrees. Some builders have granted extensions or other relief on some projects, but nothing requires them to. Ask through your lawyer, early, and get any extension written into an amendment to your agreement.

Does Tarion protect my deposit if I can't close?

No. Tarion's deposit protection applies when the builder cancels or fundamentally breaches the agreement, not when the buyer defaults.
