This is off topic, but we just got agreement from a seller on the house we're buying. And we locked in a 4.375% interest rate on a 30 year fixed mortage today, which is unreal. Given the fed cuts yesterday, I suppose the going rates might drop even lower. But these are historic numbers and so I feel pretty good about locking them in.
Anyway, in playing with numbers over the past few weeks, I've made heavy use of Karl's Mortgage Calculator. There are more options, which might mean it seems less user-friendly than some of the others. But for our purposes, it's been terrific. Thought I'd pass it on.
