Deposits & financing
Do I need a mortgage pre-approval to buy pre-construction?
Builders usually require a mortgage pre-qualification letter within days of signing. It satisfies the builder, not you. It is not a financing condition and gives you no right to exit. Final approval happens close to your actual closing, years later.
Yes, you will almost certainly be asked for one, and it is important to understand what it does and does not do.
What the builder wants
Most builder agreements require you to deliver a mortgage pre-qualification or pre-approval letter from a recognised lender or mortgage brokerage, typically within 15 to 30 days of signing. Failing to deliver it can itself be a default under the agreement.
The builder’s purpose is straightforward: they are committing a lot to you for several years and want evidence you are a real buyer.
What it does not do
It is not a financing condition. It does not let you out. It does not bind the lender to fund your purchase in 2030.
This distinction is the one that matters, because the language sounds protective and is not. There is generally no financing condition on a builder purchase, and no cooling-off period on freehold. The pre-approval letter does not change either fact.
Why a pre-approval cannot carry a long closing
A pre-approval reflects, as of today:
- Your income and employment
- Your credit
- Current rates and the qualifying stress test
- Current lender guidelines and the current property value
Every one of those can change before a low-rise home closes three or four years out. Approvals are not portable across that distance, and your actual mortgage is underwritten in the months before closing, on the facts and rules that exist then. What can go wrong.
How to use it well anyway
Qualify at a stress-tested, conservative number, not the maximum a lender will write today. You are buying the right to borrow at an unknown rate, so leave real headroom.
Use a broker who does pre-construction. The useful questions are about closing years out, not about the best rate this week.
Model the all-in cash requirement, not just the mortgage: deposit schedule, land transfer tax, levies and adjustments, and your HST position.
Keep it current. Revisit with your lender annually through the build. A change in your income or credit is far easier to manage when it is discovered two years before closing than two months.
A note on who to trust
The sales centre will often introduce an in-house or preferred lender. There is nothing wrong with that, and sometimes the terms are good. But their pre-approval exists to satisfy the builder’s file. Having your own lender or broker, one with no relationship to the seller, assess whether this purchase is genuinely fundable for you is a different exercise, and worth doing.
