That question is usually asked by shoppers firstly when they contact mortgage agents
You may be surprised: why the wanted super-low rate is not published in this site? In the real life, the rate depends on many different factors related both to you (credit score, down payment size, income, type and length of employment, and many-many others) and the mortgage parameters and options (we can draw an analogy between mortgages and cars: is the cheapest car - the best car?).
Internet sites of some mortgage agents lure clients with headers like "Lowest mortgage rates!", "Nobody breaks our rates!" etc. Those statements imply that this agent has the lowest rates for everyone. Unless an agent can prove this statement to be factual, they can be considered false. Consider what the agent would have to do to prove such a statement. This would require being able to state without doubt that he/she knows all of the other rates, that every brokerage and lender offer, and has the lowest of them all. If the agent is not able to prove this statement, he/she violates section 9 of Mortgage Brokerage, Lenders and Administrators Act, 2006, Regulation 187: "A mortgage broker or agent shall not include false, misleading or deceptive information in his or her public relations materials."
It is likely that we will get the desired best rate for you (after all, we work with the same lenders as those "masters of promise", and we want you to be satisfied and recommend our service), but no mortgage agent in Canada can honestly guarantee it in advance.
We will not mislead you by posting the lowest rate, existing today for a "no-frills" mortgage (you don't want it!) for a borrower with brilliant credit, huge down payment and many years on a full time position, just to attract you, and then to offer a more expensive mortgage product - we don't practice the Bait And Switch "marketing tactics". You can find the "lowest" rate in the Internet by yourself; however, to a non-ideal borrower, it, unfortunately, does not apply. But we can say with the outmost of certainty that we can get you the best rate possible in your financial circumstances.
Once you are interested in obtaining a mortgage, then you most likely will also be interested in the help of an experienced real estate agent:
