We have had years of quantitative easing and monetary policy that has kept the rates of financing charged to banks at historic lows, with our government pushing banks to lend, but not on mortgages. Easy money and terms help prices grow. Now the FED is talking about reducing rates again.
I work in higher ed -- Same thing -- every-time the government raises loan limits and drops interest rates, we all respond by increasing our tuition costs.
Money lent for cars, truck, RVs, boats is a bubble similar to the housing bubble, but it should not crash the economy if it pops like housing did.
