My big point is, Don't let the tail wag the dog. Don't let your credit score become the be-all, end-all. It's much more important to save money and work towards not needing to borrow. That's just math.
i suspect that goofytinkerbell has a different mindset towards credit scores b/c credit scoring holds some different power and has (to an extent) different implications than in the u.s. saving money and not needing to borrow for routine purchases and even moderate unexpected expenses is a great goal but it has to be challenging to budget when the norm is having your mortgage terms renegotiated every handful of years. my understanding is that while u.s. employers in some industries will run a credit report on applicants it is far more common in canada and carries much more weight in employment decisions. insurance laws in the u.s. regarding the ability of a company in a given state to weigh a credit score in approving/costing out insurance is also different to an extent.
You're saying a credit score makes it possible to rent or get a better interest rate on a purchase. Here's an example about how cash beats credit: When my daughter needed to rent a college apartment, she needed me to co-sign. Because I had savings, I was able to pay a year's worth of rent up front. This allowed me to skip the credit check (saved about $60) and I negotiated a lower monthly cost. Plus no pesky monthly payments.
we had the opposite experience. when we sold our former home there was a period of time before our new home was located. in the interim we needed to find a rental. we had excellent credit, a significant chunk of change in the bank yet every landlord was fixated on us demonstrating the ability to/a history of regular routine payments. we pointed to our mortgage history but they viewed it as 'a different animal' than smaller monthly payments (secured vs. unsecured). we explained we did'nt use credit cards much if at all so they asked for references from a 'prior landlord' (had not rented in 8 years and that place had changed ownership). offered to pay cash up front for the duration of the lease-nope b/c they wanted a documented history. we finaly were able to use of all things-our utility bills.
we've seen allot of changes to rental terms post-pandemic. even a pre-payment of rent (which most won't take due to the tax implications and further obsticales it creates if an eviction for other issues is needed) won't waive the credit check requirement for both the tenant and the landlord and none of the college apartments will rent to a 'student' absent a co-signer. once a student graduates they have to demonstrate a full year of employment that nets 3-4x the rent before they can forego a co-signer (demand outpaces supply and the landlords got terribly burned during the pandemic so they call the shots).
