Pull up your mortgage statement and look at the interest rate. If you haven’t compared it to another lender since the day you signed, there’s a good chance it’s higher than it needs to be.
New research on mortgages taken out since 2022 found that 87% of American borrowers are paying more than they need to for their home loan, an average of $3,343 a year in avoidable interest. Over the life of a 30-year loan, that adds up to $78,186, more than most Americans have saved for retirement.
The single biggest driver is also the simplest to fix: most buyers get a rate from one lender and never ask anyone else what they would offer.

You accepted the first rate you were quoted
Most people find a lender, get pre-qualified, and ride that same lender all the way to closing. It seems efficient, but mortgage pricing doesn’t reward loyalty. Two lenders can quote the same borrower on the same day and land half a percentage point apart, depending on that lender’s investor pricing, how full its pipeline is that week, and how much it wants your loan specifically.
Requesting a Loan Estimate from a second or third lender can save homebuyers $600 to $1,200 a year, and it costs nothing but an afternoon. Lenders are required to send a Loan Estimate within three business days of a request, and all you need to provide is your name, income, Social Security number, the home’s address, an estimated value, and the loan amount.
The credit score worry that stops most people doesn’t hold up under the actual rules. Multiple mortgage credit checks within a 45-day window count as a single inquiry on your credit report, so requesting quotes from five lenders costs you the same, credit-wise, as requesting one. Pull estimates from three or four lenders, put the numbers side by side, and use the lowest one to negotiate with the lender you’d actually prefer to use.
You’re still paying for insurance you don’t legally owe
If your down payment was under 20%, you’re almost certainly paying private mortgage insurance, a monthly premium that protects your lender if you default, not you. It typically runs $100 to $250 a month on a $200,000 to $300,000 loan, and federal law gives you two ways to stop paying it that most homeowners never use.
You can request cancellation in writing once your loan balance drops to 80% of your home’s original value, and your servicer is required to grant that request as long as you’re current on payments. If you never ask, PMI still has to automatically terminate once your balance is scheduled to hit 78% of the original value, based on your amortization schedule.
The difference between those two dates can run a year or more on a typical 30-year loan. Ask your servicer for your amortization schedule, find the date your balance crosses 80%, and put it on your calendar now. If your home has appreciated faster than your loan has paid down, and plenty have over the past few years, you may already be past that point and simply haven’t asked.
Your credit score improved and your mortgage never found out
Your interest rate was set the day you applied, based on the credit score you had at that exact moment. If your score has climbed since then, maybe you paid off a card, cleared a collection, or just kept making payments for a few more years, your current mortgage has no way of knowing that and no mechanism to reward you for it automatically.
That difference can be substantial. Moving from a 620 credit score to 760 or higher on a $300,000, 30-year loan can save roughly $156 a month and $56,103 in total interest over the life of the loan. Even smaller jumps matter, since lenders price mortgages in tiers that typically move in 20-point increments.
The only way to capture that improvement is to refinance or, if your existing lender offers it, request a rate modification. Check your score before you do either. If it’s climbed a full tier or two since you closed, run the numbers on a refinance and compare the new rate against your current one before deciding it isn’t worth the paperwork.
Your escrow account might already be holding money that’s yours
If your mortgage payment includes property taxes and homeowners insurance, that money sits in an escrow account until your servicer pays those bills on your behalf. Once a year, the servicer runs an analysis to check whether it collected too much, too little, or the right amount.
When the analysis turns up a surplus, the servicer has to refund it within 30 days if the amount is $50 or more. That refund can happen because your property tax assessment came in lower than expected, because you shopped and found a cheaper homeowners insurance policy, or simply because the servicer overestimated your bills for the year.
Most homeowners never check whether that annual analysis happened, or whether the letter that came with it mentioned a refund. Dig up your last escrow statement, or call your servicer and ask directly whether your account currently shows a surplus. If your property taxes or insurance premiums dropped in the past year and your monthly payment hasn’t changed to reflect it, there’s a reasonable chance you’re due money back.
You locked in during the high-rate years and never checked again
Mortgage rates peaked at 7.79% in October 2023, the highest level in 23 years, and plenty of buyers closed on homes during that stretch because they couldn’t afford to wait any longer. Today’s average sits at 6.65% for a 30-year fixed loan, more than a full percentage point lower.
A percentage point on a $350,000 loan is worth checking. On that loan size, the difference between 7.79% and 6.65% works out to roughly $260 a month, or more than $3,100 a year, before accounting for what refinancing costs to set up.
Refinancing isn’t free. Closing costs on a refinance average $2,403, so the real question is how many months it takes for the monthly savings to cover that upfront cost. Divide the closing costs by your expected monthly savings to find your break-even point, then compare that number to how long you plan to stay in the house. If you’ll be there past the break-even point, the numbers favor refinancing. If you bought or refinanced any time from 2022 through 2024, this is worth ten minutes with a mortgage calculator.
You paid closing costs without asking which fees move
The national average for mortgage closing costs on a home purchase was $4,661 in 2025, and not every line item on that bill is fixed. Lender fees like origination charges and processing fees are often negotiable, especially if you have strong credit or a competing offer in hand. Third-party fees like the appraisal and credit report are harder to shop, but title insurance and the title company itself usually aren’t locked in by your lender.
Ask for a written breakdown of your Loan Estimate and go through it line by line. If an origination fee looks high compared to what other lenders quoted you, say so directly and ask the loan officer to match or beat it. Lenders would rather shave a few hundred dollars off a fee than lose the loan entirely to a competitor.
This works best when you’ve already collected quotes from more than one lender, since a number on paper from a competitor gives you something concrete to negotiate against. Without it, you’re asking a lender to lower a fee out of goodwill, and that rarely gets you very far.
