@Raybyrnes I also think people are fooling themselves if they think interest rates are going to stay this low forever so loan notes and cash flow will impact overall long term costs.
This is what this ‘renter’ is betting on. As interest rates rise, the prices that equivalent houses sell for will drop. Most people only look at the monthly payments for what they can buy and what they perceive it is worth. Since I am sitting on a whole pile of cash (could buy right now for cash, but won’t) I want to get the best return on my cash. You can view the return on invested down payment as being equivalent to the mortgage rate (because that is the rate and cost is offsets).
