We started seriously looking for houses to buy in April, and got a rate of 5.125% later that month. We were really hoping for something <5%, but I'm grateful that we didn't wait too much longer.
Of course, now the "worry" is that rising rates will sink the market value. So long as I keep my job or can still find another easily, that's not much of a concern; but the prospect of a recession, with layoffs and hiring freezes, is in the back of my mind.
