A 7% mortgage looks like a single number on a lender’s website. It isn’t. Your quoted rate is a stack of four or five separate figures, and only one of them comes from the Federal Reserve. That’s why the question “why are mortgage rates so high?” usually gets an answer that doesn’t match the quote sitting on your desk.
What follows is a walkthrough. Dig out your most recent loan estimate, open a calculator, and work through the five steps below. By the end you’ll know which slice of your rate belongs to the bond market, which belongs to the lender, and which belongs to your own credit file.
Your Rate Is a Stack, Not a Single Number
Every mortgage quote gets built in layers:
- the base yield investors demand, which tracks the 10-year Treasury
- the lender’s markup, known as the primary mortgage spread
- risk adjustments tied to your credit score, down payment, occupancy and property type
- discount points and origination fees you’ve agreed to pay
The macro layers are worth understanding on their own, and the structural drivers behind today’s rate environment are covered elsewhere on this site. But knowing that inflation is sticky tells you nothing about whether your specific quote is fair. That takes arithmetic, and it starts with the bond market.
Step 1: Find the Market Baseline Before You Blame Anyone
Start with the 10-year Treasury yield. Mortgage rates don’t follow the Fed’s overnight rate, even though the headlines imply they do. They follow long-dated government bonds, because the average 30-year fixed mortgage gets paid off, refinanced or sold within about seven to ten years. Investors price that reality into the bond they’re buying.
So if the 10-year Treasury yields 4.25%, that’s your floor. Now add the spread, the extra yield investors demand for holding a mortgage-backed security instead of a government bond. Before 2008 that spread hovered near 1.5%. Since 2022 it has spent long stretches between 2.4% and 2.8%.
4.25% + 2.60% = 6.85%.
That is the going rate for a clean, low-risk borrower right now. If you have strong credit and 20% down and you’re quoted 6.9%, nobody is ripping you off. If you’re quoted 7.9%, the extra percentage point is coming from your file, and Step 2 finds it.
Step 2: Subtract the Add-Ons That Are About You, Not the Economy
Lenders publish these as loan-level price adjustments, usually in a grid. Two or three thresholds on that grid will explain most of the gap between your quote and the baseline.
Credit score bands
Pricing moves in roughly 20-point steps. A 760 score sits in the best tier. Slip to 699 and you cross into a band that adds 0.25 to 0.75 points in cost, depending on everything else in the file.
Loan-to-value thresholds
80% is the line that matters most, followed by 75% and 90%. Under 80% you get the best pricing. Above 90%, expect add-ons between 0.75 and 1.5 points. Put 5% down with a mid-range score and you can stack more than a full point of extra cost onto the baseline.
The rest of the form
- Investment property or second home: add roughly 1.125% to 3.375% in points
- Cash-out refinance instead of a purchase: higher across the board
- Condos in buildings with occupancy or litigation problems: lender-specific penalties
- FHA and VA loans: priced on entirely different grids
Here’s how it looks in practice. Two neighbours buy identical $400,000 houses on the same street in the same week. Sarah puts 20% down with a 760 score and is quoted 6.875%. Mark puts 10% down with a 680 score, and his add-ons total about 1.5 points. He can pay roughly $5,400 upfront on his $360,000 loan, or trade that cost for a rate near 7.375%.
Same block. Same lender. Half a percentage point of difference, none of it caused by the Fed. One credit score and one down payment did that.
Step 3: Price the Points and Origination Fees Honestly
One discount point costs 1% of the loan amount and typically buys about 0.25% off your rate. On a $320,000 loan, that’s $3,200 to move from 6.875% down to 6.625%.
The monthly payment falls from roughly $2,102 to $2,049. That’s $53 a month, or $636 a year. Divide the cost by the saving and your break-even lands a little past five years.
So if you plan to sell or refinance within three years, points are a gift to the lender. Stay fifteen years and they’re one of the better returns available to you.
Origination fees work differently. They run 0.5% to 1% of the loan and lower nothing. Always compare quotes with fees included, because a headline rate that’s 0.125% lower can cost you more once a 1% origination fee is added on top.
Step 4: Compare Against Real History, Not a Memory
Someone will tell you they paid 12% in the 1980s and you should count yourself lucky. They remember the number correctly and take the wrong lesson from it.
The 30-year fixed averaged 18.45% in October 1981, the peak of a rate cycle that makes 7% look almost gentle. The median new home that year sold for about $68,900. Financing 80% of it at 18.45% produced a payment near $850 a month, against a median household income of roughly $1,800 a month before tax.
Then apply the obvious correction, because a 1985 mortgage at 12% was repaid in 1985 dollars. You can run an old rate through an inflation adjustment and the comparison shifts again, in both directions.
The useful takeaway isn’t comfort. It’s calibration. Rates near 7% are strange to anyone who started paying attention after 2009, and thoroughly ordinary across the past fifty years.
Step 5: Rank the Levers That Actually Move Your Number
Five things change your rate, and they cost wildly different amounts of effort.
- Credit score. Twenty or forty points can shift a band. Paying a revolving balance below 30% of its limit often does it inside one billing cycle, and it’s free.
- Loan-to-value. Crossing 80% or 75% is a genuine discount. A larger down payment, a cheaper property, or a price negotiation gets you there.
- Lender shopping. Three quotes on the same morning for the same file commonly vary by 0.375% to 0.5%. Fastest win on the list.
- Loan structure. A 15-year fixed prices lower with a bigger payment. An adjustable-rate mortgage prices lower still, with the risk parked in year six.
- Points. Cash today for a lower rate tomorrow, with a break-even you can calculate in under a minute.
Rank them by cost. Fixing your credit costs nothing but a few weeks. Buying the rate down costs thousands.
What to Do When the Market Half Won’t Budge
Treasury yields and the primary mortgage spread are not things you negotiate. What you can do is refuse to pay for the parts that aren’t yours.
Get loan estimates from three lenders on the same day, then ask each one to break out the loan-level price adjustments line by line. Ask what rate they’d offer at 80% loan-to-value, or with a 740 score, or with zero points. Ask whether the seller will fund a temporary buydown rather than cut the price, since seller-paid points reduce your payment without taking as much off what the seller nets. If your timeline is flexible, waiting a quarter is a legitimate strategy. If it isn’t, an adjustable-rate loan with a fixed period longer than your expected stay is another.
Set the three estimates side by side and the question changes. It stops being why mortgage rates are so high and starts being which of these four numbers can I move by Friday.
