I’m about to lock in a 30 year fixed mortgage cash out refinance at 3.625% and I can’t imagine that I’m ever going to have much regret at that rate. Even in a world where I don’t get a tax deduction because I no longer itemize, that’s an amazingly low rate for a 30-year fixed period.
Whether it’s a good idea to buy a house in your market, now that’s a different question.
