So we're here today talking about mortgages, and one of the topics I hear a lot about when people are thinking about mortgages is refinancing. When do I want to refinance? Why is it so important? What [does that] even mean?


Yeah, so we'll touch upon a few things, here. Why you've been hearing a lot about it is because mortgage rates, if you look over the long term, are at multi-decade lows. Now they've come up a little bit from the very lows, but it's still a good time to refinance. And essentially the basics of it are a refinance is taking your existing mortgage that may be at a high rate and getting a lower rate to save money.


Sounds like a great way to save a couple of extra dollars, right?


Yes, absolutely.


So how, actually, would you know whether it's the right time, now, to go for a refinance?


It's a good question, because if you look at it, will rates go higher? The Fed has signaled that there may be two or three rate increases in 2017, so mortgage rates may increase. Is now the right time to do it? Some people look at the macro picture and [ask], "OK, what are rates going to do?"

I actually think there's a more concrete way to look at it a simpler process. Just look at the savings that you'll get on your monthly payment and figure out how long you're going to live in your home. Essentially by figuring out those costs you have your breakeven point.

So if you're going to save, say, $2,400 on a mortgage and you're going to stay in your house for the next five years, obviously you're going to pass that breakeven point. That's really what you want to look at. Am I actually going to save money, or am I going to be moving in the next year or two? Maybe it doesn't make as much sense to refinance.


So such a quick and simple calculation can actually be very helpful in figuring out, "Is this right for me?" And we don't want to be predicting the future. Nobody can do that.


Yes, don't complicate it.


Exactly. With your simple formula you can figure out if this is the right time for [you] to consider this.
