I don't mean on an individual basis at a point in time, e.g. Person A today can get a loan at 2% and Person B at 4%. I mean the interest rate environment as a whole.
Mathematically, it doesn't make any difference for the BUYER if interest rates are around 0% or 20%. You get the same house either way. Low interest rates don't mean you can afford more house.
It's the same thing if you're buying a car on credit. Affording a Honda with 10%-down-17%-interest doesn't mean you can afford a Lexus with zero-down-zero-interest. You can afford the same car either way. The only beneficiary of low interest rates is Honda/Lexus itself because it can sell cars at higher prices.
It blows my mind that people don't understand this.
