Refinancing your mortgage can lower your monthly payment, reduce the amount of interest you pay, shorten the time until your house is paid off, or give you access to home equity. But a lower interest rate does not automatically mean refinancing is a good deal.

The important question is not simply, “Can I get a lower rate?”

The better question is:

“After the fees, the new loan term, and the amount of time I plan to keep this mortgage, will refinancing actually put me in a better financial position?”

That is what this guide will help you figure out.

What does refinancing mean?

Refinancing means replacing your current mortgage with a new mortgage.

Your new lender uses the new loan to pay off the old mortgage. You then make payments on the new loan instead.

You might refinance to get a lower interest rate, lower the monthly payment, change from an adjustable rate to a fixed rate, shorten the loan term, remove certain mortgage costs when possible, or take cash out of the equity in the home.

When Can Refinancing Be Worth It?

There is no rule saying a mortgage must drop by exactly 1 percent before refinancing makes sense.

A smaller rate reduction can sometimes be worthwhile on a large mortgage. A much larger rate reduction can still be a poor decision when closing costs are high or the homeowner plans to move soon.

Reason 1: Lower the interest rate

Suppose $350,000 remains on a mortgage at 7.25 percent.

A refinance offer at 6.25 percent may reduce the monthly principal and interest payment, depending on the new term.

But the savings need to be compared with the cost of getting the new mortgage.

Reason 2: Lower the monthly payment

A lower payment can create more room in the monthly budget.

Be careful, though.

A payment can also become lower simply because the debt has been stretched over more years.

That is not the same thing as saving money.

Reason 3: Pay the house off sooner

A homeowner with 25 years remaining might refinance into a 15 or 20 year loan.

The payment could increase, but the mortgage may be paid off sooner and total interest may be lower.

Reason 4: Change the type of mortgage

Someone with an adjustable rate mortgage may want the predictability of a fixed rate mortgage.

A fixed rate means the mortgage interest rate does not change during the loan term, although the total housing payment can still change because of items such as taxes or insurance.

Reason 5: Access home equity

A cash out refinance allows the homeowner to borrow more than the amount needed to pay off the existing mortgage and receive part of the difference as cash.

This can provide access to a large amount of money, but it also increases mortgage debt and places the home behind that debt.

Do This Math Before You Refinance

Start with the current loan.

For a simple example:

Now suppose a lender offers a new 25 year mortgage at 6.00 percent.

The new principal and interest payment would be roughly $1,933 per month before taxes, insurance, mortgage insurance, or other housing costs.

That is approximately $187 per month less.

At first, that sounds great.

But suppose getting the new mortgage costs $6,000.

Now the question becomes:

How long will it take the $187 monthly savings to recover the $6,000 cost?

That is the break even calculation.

Calculate the Break Even Point

The break even point tells you approximately how long it takes for monthly savings to recover the upfront cost of refinancing.

A simple calculation is:

Refinance costs ÷ monthly savings = approximate break even period

Example

Closing costs: $6,000

Monthly savings: $187

$6,000 ÷ $187 = approximately 32 months.

That means it takes roughly 2 years and 8 months to recover the $6,000 through the monthly payment savings in this simplified example.

If the homeowner expects to keep the mortgage for another ten years, that may be worth investigating.

If the homeowner expects to sell the house next year, paying $6,000 to save $187 per month would probably not have enough time to recover the cost.

What if the lender says there are “no closing costs”?

Ask what that actually means.

Sometimes the costs are being added to the loan balance.

Sometimes the borrower receives a lender credit in exchange for accepting a higher interest rate.

Sometimes certain fees are waived while other costs remain.

“No closing cost” does not necessarily mean nobody is paying for the refinance.

One of the Best Tricks: Shop More Than One Lender

Do not assume the bank holding the current mortgage will automatically give the best refinance offer.

Get quotes from multiple lenders within a focused shopping period.

Consider banks, credit unions, mortgage brokers, online mortgage lenders, and the current mortgage company.

Compare offers on the same day when possible

Mortgage rates can move.

A quote from Monday and another quote several weeks later may not be a fair comparison.

Try to compare similar loan terms, similar rate lock periods, and similar amounts on the same day or within a short period.

Do not ask only, “What is your rate?”

Ask:

What interest rate are you offering?

What is the APR?

Are points required to get that rate?

What lender fees are being charged?

What are the estimated total closing costs?

Is there a lender credit?

How long is the rate locked?

What will the new loan balance be?

Is there a prepayment penalty?

Now there is enough information to compare the offers rather than comparing advertisements.

Interest Rate vs. APR: Know the Difference

This is one of the most important things to understand when comparing mortgage offers.

Interest rate

The interest rate is the rate used to calculate interest on the mortgage.

APR

APR stands for annual percentage rate.

APR is designed to reflect the interest rate plus certain loan costs, expressed as an annual rate.

That makes it useful when comparing loans, although it should not be the only number considered.

Example

Lender A advertises a 5.75 percent interest rate.

Lender B offers 5.90 percent.

It looks like Lender A is automatically better.

Then you discover Lender A requires thousands of dollars in discount points and fees to obtain 5.75 percent.

Lender B charges far less upfront.

The better choice now depends partly on how long the loan will be kept.

A lower advertised rate can be more expensive to obtain.

Understand Mortgage Points Before Paying for Them

A discount point is an upfront fee paid to the lender in exchange for a lower mortgage interest rate.

One point generally equals 1 percent of the loan amount.

Example

New mortgage: $400,000

One point: $4,000

Two points: $8,000

Paying points can make sense when the lower rate produces enough savings and the mortgage will be kept long enough to recover the upfront cost.

Run another break even calculation

Suppose paying $4,000 in points lowers the payment by $85 per month.

$4,000 ÷ $85 = about 47 months.

That is almost four years.

If the homeowner expects to refinance again or sell before then, paying the point may not produce enough time to recover its cost.

If the loan will be kept for 15 years, the calculation may look very different.

Watch Out for Restarting the Clock

This is one of the easiest refinancing mistakes to make.

A homeowner originally took a 30 year mortgage.

Ten years have passed.

Only 20 years remain.

Then the homeowner refinances into a brand new 30 year mortgage.

The new payment may look dramatically lower because the remaining debt is now being spread over another 30 years.

But the homeowner has also extended the payoff date by another ten years.

A lower payment is not always a lower cost

Suppose the goal is to reduce the interest rate without extending the debt unnecessarily.

Ask the lender for a 20 year option.

Also compare 15, 20, 25, and 30 year terms when appropriate.

Another strategy is to take the lower required payment but voluntarily continue paying an amount closer to the old payment, provided the new loan allows additional principal payments without penalty.

That can provide payment flexibility while still helping reduce principal faster.

Look at total interest, not just this month’s payment

The loan estimate and amortization information can help show how much interest is expected over time.

Someone saving $250 per month but adding ten more years of payments should understand that tradeoff before signing.

Be Careful With Cash Out Refinancing

A cash out refinance can turn part of home equity into spendable cash.

Simple example

Home value: $500,000

Current mortgage balance: $250,000

New mortgage: $320,000

The old $250,000 mortgage is paid off and part of the additional borrowing may become cash to the homeowner after applicable costs and adjustments.

The exact amount depends on the transaction.

Why do people do this?

Common reasons include home improvements, debt consolidation, major expenses, or other financial needs.

The danger

Cash from a refinance is not free money.

It is new debt secured by the home.

Using home equity to pay off $40,000 of credit card debt can reduce the interest rate on that debt, but it can also turn unsecured debt into debt connected to the house.

And if the credit cards are paid off only to be charged back up again, the homeowner can end up with a larger mortgage and new credit card balances.

Before using a cash out refinance for debt consolidation, address the spending or cash flow problem that created the debt.

How to Refinance Your Mortgage Step by Step

Step 1: Pull out the current mortgage statement

Write down the balance, rate, payment, loan type, and remaining term.

Step 2: Decide what refinancing is supposed to accomplish

Lower payment?

Lower interest cost?

Shorter payoff period?

Fixed rate?

Cash out?

A clear goal makes offers easier to compare.

Step 3: Check credit and finances

Lenders may evaluate credit, income, employment, debts, assets, property value, and other factors.

A stronger financial profile can affect available rates and terms.

Step 4: Estimate the home’s value

Home equity can affect refinance options.

A lender may require an appraisal or use another approved valuation method depending on the transaction.

Step 5: Get several quotes

Ask each lender for the same basic loan structure so the comparison is useful.

Step 6: Compare the Loan Estimates

Look beyond the payment.

Compare rate, APR, points, lender fees, estimated cash needed to close, loan amount, term, and other costs.

Step 7: Calculate the break even point

Determine approximately how long it will take to recover the refinancing costs.

Step 8: Choose the lender and lock the rate when appropriate

A rate lock generally protects the quoted rate for a defined period, subject to its terms.

Ask how long the lock lasts and what happens if closing takes longer.

Step 9: Provide documents quickly

The lender may request pay information, tax documents, bank statements, insurance information, mortgage statements, identification, and other documentation.

Step 10: Review the final numbers before closing

Do not assume the final loan matches the first conversation.

Check the rate, loan amount, monthly principal and interest, cash needed at closing, lender credits, points, fees, escrow information, and loan term.

Step 11: Close the new mortgage

After the refinance closes and the old mortgage is paid off, verify that the old lender shows the loan as satisfied and begin payments according to the new lender’s instructions.

Refinancing Tips That Can Save Real Money

Ask the current lender to compete

After receiving a strong written offer elsewhere, ask the current mortgage company whether it can beat or match it.

Do not bluff. Use a real competing offer.

Negotiate lender fees

Some costs are more negotiable than others.

Ask whether lender origination, underwriting, processing, or similar lender controlled charges can be reduced or offset.

Compare the same rate with different fees

One lender offering 6.00 percent with $8,000 of costs and another offering 6.00 percent with $5,000 of costs are not offering the same deal.

Ask about a shorter term

If 22 years remain on the mortgage, do not automatically accept another 30 year loan.

Ask what a 20 year loan would look like.

Consider paying the old payment after refinancing

Suppose refinancing reduces the required principal and interest payment from $2,500 to $2,200.

If the budget already comfortably handled $2,500, continuing to pay $2,500 and directing the extra amount toward principal may help pay the mortgage down faster, subject to the loan’s terms.

Improve the financial profile before applying when practical

Reducing credit card balances, avoiding unnecessary new debt, correcting credit report errors, and keeping finances stable before applying may improve the borrowing picture.

Do not open a new car loan in the middle of the refinance

A major new debt can change the financial information used by the mortgage lender.

Before making a large credit purchase while a refinance is underway, understand how it could affect approval.

What to Watch Out For

“We can lower your payment by $500.”

Ask how.

Was the interest rate reduced?

Was the loan stretched back to 30 years?

Was cash added to the balance?

Are taxes and insurance being compared consistently?

Very low advertised rates

The advertised rate may require excellent credit, a particular loan size, a large amount of equity, discount points, or other conditions.

Ask for the rate available for the actual application.

Large points for a small rate improvement

Calculate how many months it takes to recover the cost.

Rolling every cost into the mortgage

This can reduce the amount of cash needed at closing, but it also means borrowing the costs and potentially paying interest on them.

Cash out for ordinary spending

Using decades of home equity for vacations, shopping, or recurring lifestyle expenses can turn short lived purchases into long term debt.

Ignoring the new payoff date

Always compare when the current mortgage would end with when the new mortgage would end.

Focusing only on the rate

A low rate with expensive points and fees may not be the best offer.

Refinancing repeatedly

Every refinance should stand on its own math.

Repeatedly paying closing costs and restarting longer loan terms can reduce or erase the benefit of lower rates.

Pressure to sign immediately

Mortgage rates can change, but that does not mean a borrower should sign documents they do not understand.

Ask questions and read the actual loan disclosures.

A Full Refinance Example

Marcus has the following mortgage:

Balance: $325,000

Interest rate: 7.25 percent

Time remaining: 26 years

He starts receiving advertisements promising a much lower monthly payment.

Instead of immediately applying with the first company, Marcus gets three quotes.

Offer A

6.25 percent interest rate

30 year term

$4,500 estimated refinance costs

Offer B

6.00 percent interest rate

30 year term

$9,000 estimated costs because the offer includes discount points

Offer C

6.25 percent interest rate

25 year term

$5,000 estimated costs

At first, Offer B looks best because it has the lowest rate.

Then Marcus looks deeper.

He does not want to restart a 30 year mortgage after already paying for several years.

He also learns that the lower rate in Offer B requires significantly more money upfront.

Offer C deserves serious attention because it reduces the rate while keeping the payoff schedule much closer to the current mortgage.

Marcus then asks each lender for an updated Loan Estimate with comparable assumptions, calculates the break even point, checks the total cost over the period he expects to own the house, and asks whether any lender fees can be reduced.

The lesson is that the lowest advertised rate did not automatically produce the best refinance.
