Realtors who work with new construction sales operate in a category that looks like real estate on the surface but runs by a completely different set of rules. The builder is the seller, and unlike a typical seller who is emotionally attached to their home and open to negotiation on terms, a builder is a corporation with standardized contracts, fixed pricing structures on most items, and a legal team that has reviewed every clause of the purchase agreement many times over. Walking into a new construction transaction without understanding this dynamic is how buyers get into agreements they do not fully understand and how realtors damage their credibility.

Registering Your Client With the Builder

One of the most important steps in a new construction transaction is registering yourself as your client representative with the builder sales centre before your client makes contact with the builder directly. Most builders will pay a realtor commission on a sale when the realtor has registered the client first and is present at the initial appointment. Builders have varying policies on this: some will honour a registration even if the client visited the sales centre independently, and others will not pay any commission if the client has already spoken with the sales staff without a realtor registered.

Know the registration policy of every builder you are taking clients to before you walk through the door. Call the sales centre, ask specifically about their registration policy and commission structure, and get the registration confirmation in writing. A client who visits a sales centre without you and falls in love with a property is a client you may help but not be compensated for, depending on builder policy.

Understanding the Builder Purchase Agreement

Builder purchase agreements are not the standard OREA or provincial association agreements that realtors work with in resale transactions. They are typically long, complex documents drafted by the builder legal team and weighted significantly in the builder favour. Common clauses that buyers are surprised by include: the builder right to delay occupancy by extended periods, sometimes up to a year or more beyond the original estimated occupancy date; the buyer obligation to accept the home as built with only limited ability to request changes; closing cost adjustments that can add tens of thousands of dollars to the purchase price beyond the listed price; and limited assignment rights that restrict the buyer ability to sell the agreement before the building is complete.

Your role is not to provide legal advice on these agreements. Your role is to ensure your buyer client reviews the purchase agreement with a real estate lawyer who has experience in new construction before signing. This is non-negotiable. A buyer who signs a builder agreement without independent legal review has given up protections they did not know they had and accepted obligations they may not understand.

Closing Cost Adjustments: The New Build Expense Most Buyers Miss

New construction purchases in Canada are subject to a range of closing cost adjustments that do not appear in resale transactions and that can add $30,000 to $80,000 to the total cost of the purchase beyond the listed price. These typically include development charges passed through from the municipality, Tarion warranty enrolment fees in Ontario, utility connection fees, education development charges, and HST adjustments for the new home rebate.

Many new build buyers are shocked when they receive their statement of adjustments from the builder lawyer a few weeks before occupancy. Buyers who are not financially prepared for these adjustments, or whose mortgage financing does not account for them, face a genuinely difficult situation. Walk through the estimated closing cost adjustments in detail with any buyer considering a new construction purchase and ensure they have a realistic understanding of what their total investment will be before they sign.

Building Relationships With Builder Sales Teams

Realtors who develop strong relationships with builder sales representatives gain access to information and opportunities that are not available to agents who simply show up at the sales centre. Early access to project launches, notification of inventory releases before they are publicly announced, and better communication when clients have questions or issues during the construction period are all benefits of being known and respected by the builder sales team.

Treat builder sales representatives as professional partners rather than as opponents or gatekeepers. Bring prepared, well-qualified clients. Follow through when you commit to bringing someone for an appointment. Communicate clearly and professionally throughout the transaction. A realtor who consistently delivers quality clients and handles transactions professionally will be welcomed by builder sales teams and will find the relationship produces business for years.
