I found the house myself. Can I still get cash back?
Most buyers find their home online. That is fine. What matters is that your agent writes the offer and is recognised as your representative.
Bring your agent in before you reach out
If you call the listing agent, book a private showing or walk into an open house alone and give your details, the listing brokerage may treat you as their customer. In BC, the listing agent cannot represent you, and in Florida you may end up in a transaction without your own agent being paid.
Already visited?
Tell your agent everything: when you visited, who you spoke to, what you signed. Often it can still be handled, but the earlier your agent knows, the better.
What your agent does for the rebate
Pulls comparable sales, reviews strata documents or HOA packages, writes and negotiates the offer, handles subjects or contingencies, and manages the deal to completion. That is why they earn a commission, and why sharing part of it with you is a real saving.
