Legal review

Critical during statutory review period

A pre-construction purchase is a long-dated financing commitment

A buyer can sign today and close years later. Their income, debts, credit, employment, interest rates, mortgage rules and the property's market value can all change before lender funds are required. A pre-approval obtained at signing should never be described as a guaranteed mortgage for final closing years in the future.

For Realtors, the financing conversation should happen twice: at purchase, to test whether the commitment is reasonable, and again well before occupancy/final closing, to rebuild the file using current facts and current lender policy.

Use the legal review period to test the financing assumptions too

Tarion and HCRA materials emphasize legal review of pre-construction purchase documents, and Ontario condo buyers have a statutory cooling-off period. The lawyer should review the agreement, disclosure package, adjustments, assignment restrictions and termination provisions. In parallel, the mortgage professional can stress-test the purchase price, projected closing costs and likely qualification rather than pretending to approve a distant closing.

The Realtor should not replace legal review with a summary of builder sales material.

Interim occupancy is not final closing

Tarion explains that a condominium purchaser may occupy a completed unit before the condominium is registered and title transfers. During interim occupancy, the purchaser pays an occupancy fee that can include interest on the unpaid purchase balance, estimated municipal taxes and projected common expenses.

The mortgage usually funds at final closing when title can transfer, not simply because the buyer receives occupancy. That distinction matters for cash-flow planning and for clients who assume their mortgage payment starts the day they get keys.

Start rebuilding the mortgage file well before expected closing

Once a credible occupancy/final-closing window emerges, the buyer should update income, credit, liabilities, down-payment evidence and the expected statement of adjustments. New-construction closing adjustments can be material, and the buyer may need liquidity beyond the deposits already paid.

A long lead time creates room to address self-employment history, credit deterioration, newly acquired debts, changes in marital status or ownership, assignment plans and appraisal risk. Waiting for the builder's final notice can compress every option.

  • Reconfirm current income and employment.
  • Review debts and any new financed obligations.
  • Trace remaining down payment and closing funds.
  • Estimate taxes, legal costs and builder adjustments with the lawyer.
  • Confirm occupancy versus final-closing dates.
  • Discuss appraisal/value risk and backup liquidity.
  • Review assignment or title-holding changes with lawyer and mortgage professional before acting.

The contract price may be years old; the lender still values the property at closing

If market value falls below the contract economics, the purchaser can face an appraisal or lending-value shortfall at the same time they are legally required to close. If value rises, that does not automatically mean the lender will finance every closing adjustment or permit the buyer to extract the increase.

The mortgage professional should model the lender's current lending value and the cash required under a lower-value scenario.

Realtor pre-construction closing checklist

A Realtor adds the most value by preserving the timeline, coordinating professionals and preventing assumptions from becoming emergencies.

  • Keep executed APS, amendments and assignment documents organized.
  • Track builder notices and critical dates.
  • Encourage lawyer review of material amendments and closing adjustments.
  • Reconnect the buyer with the mortgage professional months—not days—before closing.
  • Do not call interim occupancy 'closing' when title has not transferred.
  • Flag changed occupancy plans, rental plans or purchasers before lender submission.

Frequently asked questions

Does the buyer need a mortgage during interim occupancy?

Typically the purchaser does not receive title during interim occupancy, so the long-term mortgage commonly funds at final closing rather than at initial occupancy. The exact structure should be confirmed with the lawyer, builder documents and lender.

Can a buyer rely on the mortgage pre-approval they received when they bought the pre-construction unit?

No long-dated pre-approval should be treated as a guarantee. The buyer can be re-underwritten under the income, credit, rate, policy and property-value conditions that exist closer to closing.

What is the Realtor's biggest pre-construction financing mistake?

Waiting until the builder gives short final-closing notice before rebuilding the mortgage file. Early review preserves more options.
