Sort of true. We bought our house in 2008 and got a 3-something% API fixed-rate mortgage. We hate this town and we know where we want to move, but we can't afford a higher rate mortgage, which we would have anywhere we moved. My wife has amazing credit and the house is in her name only (my credit is shit), so she'd still get a decent loan, but fixed-rate and anywhere near 3%? Probably not anymore.
My old car blew its head gasket (thanks Stellantis) so we also had no choice. Check leases. It was the same price to lease brand new as it was for us to buy a certified pre-owned car and the rate was better because it was a new car. We also have excellent credit.
