Buying Pre-Construction in Canada: Mortgage Guide (2026)

Buying pre-construction — a condo or home from a builder before (or while) it's built — works very differently from buying a resale property. You sign and put down deposits long before any mortgage funds, and there are steps in between that catch first-timers off guard. Here's the financing side, explained.

The short answer

With pre-construction you pay deposits in instalments (often around 15–20% total) during construction, then arrange your actual mortgage near the final closing, which can be years after you signed. Key things to plan for: you can't lock a long-term rate that far out, condos have an interim occupancy period before final closing, and your finances must still qualify at closing. See pre-construction options.

The deposit structure

Instead of one down payment, builders collect deposits on a schedule — commonly something like 5% on signing, then further instalments over the following months, totalling around 15–20%. These deposits are typically held in trust and protected (e.g., under provincial new-home warranty programs like Tarion in Ontario). This is separate from your mortgage, which comes later.

Interim occupancy (condos)

For pre-construction condos, there's usually an interim occupancy period: you move in (or can rent it out) once your unit is ready, but before the building is registered and you legally own it. During occupancy you pay the builder an "occupancy fee" (roughly equivalent to interest, condo fees, and taxes) — not a mortgage payment. Your mortgage doesn't fund until final closing, when the building registers and title transfers.

The rate-hold challenge

Standard rate holds last 90–120 days — useless when closing is two or three years away. Some lenders and builder programs offer extended rate caps for pre-construction, but in general you can't lock today's rate for a far-future closing. Budget for the possibility that rates differ at closing, and revisit fixed vs. variable as closing approaches. In 2026's stable-rate climate (prime 4.45%), plan conservatively.

Qualifying at closing — not at signing

This is the biggest risk. Your mortgage is approved and funded near final closing, so you must still qualify then — at that time's rates and the stress test, with your income, credit, and debts as they stand. Don't take on new debt or change jobs right before closing, and keep your down payment funds ready. The unit's appraised value at closing also matters; if it appraises below your purchase price, you may need to cover the gap.

Assignments

Some buyers sell their pre-construction contract before final closing (an "assignment"). It's possible but governed by the builder's rules and has tax implications — get legal and tax advice before counting on it.

How it compares to building your own

Pre-construction means buying a finished product from a builder on their timeline. If you're building yourself, that's a construction mortgage with progress draws instead — a different process entirely.

Frequently asked questions

How much deposit do I need for pre-construction in Canada?

Typically around 15–20% total, paid in instalments over the construction period (often starting with 5% on signing), held in trust separately from your eventual mortgage.

When do I get my mortgage for a pre-construction home?

Near final closing — which can be years after signing. For condos, you first go through an interim occupancy period (paying an occupancy fee) before the mortgage funds at final closing.

Can I lock my mortgage rate when I sign?

Usually not for a far-future closing — standard rate holds are only 90–120 days. Some extended rate-cap programs exist, but plan for rates possibly differing at closing.

What if I can't qualify at final closing?

It's a real risk, since you qualify at closing-time rates and rules. Keep your finances stable, avoid new debt, and work with a broker early; alternative financing can sometimes bridge a gap.
