My main concern right now is that an increase in interest rates is going to cause a drop in home prices and possibly trigger another crash. For example, the relatively modest rate increases in 2018 caused a fairly noticeable swoon in the SF/Bay area housing market.
For those that think buying a house is a good hedge against inflation, it is worth considering that the best tool to combat inflation is to raise interest rates. And considering most buyers budgets are created by working backwards from the monthly payment that they can afford, higher rates naturally translate to lower prices.
And as you alluded to, in a rising interest rate environment, there are no more "escape hatches" for folks that might be struggling to make ends meet. In a rising rate environment, refinancing is off the table, selling might be off the table if you are underwater on the mortgage, etc...
I have been waiting for an opportunity to buy for quite a while now. It has always felt like our household income was a few ticks too low to comfortably afford anything but the dregs of the market. And as our pay increased, the market would rise another 20% and slip out of reach again. And right now I am seeing a few niches in the market that might work for our budget, but the interest rate situation has me spooked, so once again, I am leaning towards sitting this one out. I guess on the plus side, I can buy cryptocurrency at a 100-1 leverage ratio which was something that wasn't available to my parents generation!!!
