How Does Refinancing Work?

Fundamental mortgage Q&A: “How does refinancing work?”

When you refinance your mortgage, you are essentially trading in your old loan for a fresh one with a new interest rate and term. And possibly even a new balance.

You may elect to receive a new mortgage from the same bank that held your old loan previously, or refinance your loan with an entirely different lender.

It’s certainly worth your while to shop around if you’re thinking about refinancing, as your current lender may not have the best deal.

Regardless, the bank or mortgage lender that grants you the new mortgage essentially pays off your old mortgage with a new mortgage, thus the term refinancing.

In a nutshell, most borrowers choose to refinance their mortgage either to take advantage of lower interest rates or to cash in on equity accrued in the home.

Two Main Types of Refinancing

There are two main types of refinancing; rate and term refinancing and cash-out refinancing (click the links to get in-depth explanations of both).

Rate and Term Refinancing

Original mortgage: $300,000 loan, 30-year fixed @6.25%
New mortgage: $300,000 loan, 15-year fixed @4.50%

To put it simply, a rate and term refinance is basically the act of trading in your old mortgage(s) for a new shiny one without raising the loan amount.

In my example above, the refinancing results in a shorter-term mortgage with a lower interest rate. Two birds, one stone.  It will be paid off faster and with less interest.  Magic.

Reasons for carrying out this type of refinancing include securing a lower interest rate, moving out of an adjustable-rate mortgage into a fixed-rate mortgage (or vice versa), going from an FHA loan to a conventional loan, or consolidating multiple loans into one. And in our example, to reduce the term as well (if desired).

Lately, a large number of homeowners have been going the rate and term refi route to take advantage of the unprecedented record low mortgage rates available.  They’ve been able to refinance into shorter-term loans like the 15-year fixed mortgage without seeing much of a monthly payment increase thanks to the sizable rate improvement.

Obviously, it has to make sense to the borrower to execute this type of transaction, as you won’t be getting any cash in your pocket (directly) for doing it, but you will pay closing costs and other fees that must be considered.

So be sure to find your break-even point before deciding to refinance your current mortgage rate.  This is essentially when the refinancing costs are “recouped” via the lower monthly mortgage payment.

If you don’t plan on staying in the home/mortgage for the long-haul, you could be throwing away money, even if the interest rate is significantly lower.

Cash-Out Refinancing

Original mortgage: $300,000 loan, 30-year fixed @6.25%
New mortgage: $350,000 loan, 30-year fixed @4.75%

Now let’s discuss a cash-out refinance, which involves exchanging your existing loan for a larger mortgage in order to get cold hard cash.

This type of refinancing allows homeowners to tap into their home equity, which is the value of the property less any existing mortgages or liens.

Cash out refinancing puts money in the pockets of homeowners, but has its drawbacks because you’re left with a larger outstanding balance to pay back as a result (and there are also the closing costs, unless it’s a no cost refi).

With a cash-out refinance, you wind up with cash, but also a higher monthly mortgage payment in most cases.  In our example, the monthly payment actually goes down thanks to the substantial rate drop, and the homeowner gets $50,000 to do with as they please.

While that may sound great, many homeowners who serially refinanced over the past decade have found themselves underwater, or owing more on their mortgage than the home is currently worth, despite buying properties on the cheap years ago.

All that said, only pull cash out when absolutely necessary, because it must be paid back at some point.  It’s not free money.

Refinancing May Not Be Necessary

Despite what the banks and lenders might be chirping about, refinancing isn’t always the winning move for everyone. In fact, it could actually cost you money if you don’t take the time to crunch the numbers.

Instead of borrowing more than you need, or “resetting your mortgage,” do the math first to determine the best move for your unique situation.

One alternative to refinancing your existing home loan is to instead take out a second mortgage, often in the form of a home equity line of credit.

This keeps the first mortgage intact if you’re happy with the associated interest rate and loan term, but gives you the power to tap into your home equity (get cash) if and when necessary.

    When you refinance, you’ll just be paying off the remaining balance on the mortgage and not starting over completely from scratch, right? For example, if you’re mortgage was for $300,000 15 years ago, and you’ve paid off say, half of that. Then would you just be refinancing the remaining half, instead of paying back the original $300,000?

    Josh,

    Yes, the remaining balance of the loan would be paid off via the refinance and your new loan would take on that balance. So after 15 years on a $300k, 30-year mortgage you might have $200k or so remaining. This amount would be paid off via the refi and a new loan for around $200k would be created. Of course, one could also add cash-out on top of that amount too, in which case the loan would be bigger. But that’s optional.

    In regards to a HELOC vs a refinance: I would caution anyone against using your equity to extend a line of credit. HELOC rules change often and come with an acceleration clause meaning a bank can call the amount due in full at any time if they choose. They also have relatively shorter term limits and some turn into a fixed second mortgage upon term completion. This option should really only be used by farmers and the like who need the money upfront but, can reasonably expect to pay off the money drawn out relatively quickly. An example would be the farmer takes out a HELOC for farm equipment and after harvest, pays it off in full.

    Had loan for 33 months. Original cost of home $187,500. less 10% down; 30 year loan for $168,750 @ 4.5%. Current balance $162,000. Total payment including taxes and insurance is $1045 monthly. Current value of home $240,000. Fixed income senior citizens, have $8,500 in credit card debt (one account only – no interest until 2018 – pay $150 mo) + 42 months left on auto loan ($415 mo). $1000 in savings and 825 credit score. Would like to refinance to get rid of $55 monthly PMI. And possibly some cash out to pay off credit card debt and have some savings. Annual income is $63,000; no investments. Would it be advisable to do this and would we encounter difficulty qualifying in our current financial situation? I do not understand how cash out refi works. What principle balance would we need to finance to accomplish this and how much would our payment increase? Would it be better to just refi the current balance at a little lower rate? Would PMI drop off? Could closing costs be included in the loan?

    Linda,

    Basically if you refinance just your existing balance you’d maybe have an LTV around 67.5% ($162k/$240k). If you decided to get some cash as well, it would be added to your outstanding balance. Say you took $18k cash, it’d be roughly a $180k loan amount, or 75% LTV when divided by $240k. Potentially you could borrow up to $192k if the lender valued the home at $240k, keeping the LTV at 80% or less to drop MI. Your new payment would be based on whatever loan amount you choose, factoring in the new mortgage rate and loan term. So the payment could increase but it depends what you do and what rate you obtain via the refinance. And yes, closing costs can likely be included or paid by a lender credit so no cash has to come out of pocket.

    I got my loan on VA, but the bank keeps raising the rate saying they need to for the escrow. I’d like to refinance for a lower monthly payment. How would that work and would I have to pay anything up front to refinance?

    Connie,

    Raising the payment or the rate? Escrow might require more money each month to go toward taxes and insurance. Refinancing means to take your loan elsewhere, ideally to get a lower interest rate…and yes, there is typically an option to refi without any out-of-pocket expenses, though they are baked into the loan instead.

    I meant the monthly payment keeps going up, it started at 472/month and is now over 500/month, and I don’t think that’s the end of it either. I’m wondering if refinancing would be the way to go as I’ve only got my checks to depend on since my husband’s death earlier this year

    Connie,

    It depends why the payment is going up…is it an ARM? If so, it might be possible to refinance into a fixed loan and avoid payment increases going forward. But as mentioned, it might be going up for a different reason, such as taxes and insurance going up. Once you know why, you can act accordingly.
