Mortgage rates didn’t move much today. July's rates have remained elevated beyond what we saw in June, trending above last month's average (6.34%) for 19 days straight.
The average interest rate on a 30-year, fixed-rate mortgage ticked down to 6.48% APR, according to rates provided to NerdWallet by Zillow. This is one basis point lower than yesterday and one basis point lower than a week ago. (See our chart below for more specifics.) A basis point is one one-hundredth of a percentage point.
Mortgage rates are under upward pressure right now as investors have been reacting to renewed conflict in Iran. Ongoing fighting has pushed fuel prices higher and weakened the bond market, which in turn influences mortgage rates.

📈 What influences mortgage rates?
Mortgage rates are constantly changing, since a major part of how rates are set depends on reactions to new inflation reports, job numbers, Fed meetings, global news ... you name it. For example, even tiny changes in the bond market can shift mortgage pricing.
There aren't any more major economic reports scheduled to drop in the coming days, and the main thing that Nerds are watching is news about the war in Iran.
Crude oil prices rose 10% last week, as renewed fighting in the region threatens to push inflation up again.
When oil prices go up, it becomes more expensive to produce and ship products, which can drive inflation. When mortgage lenders suspect that the value of the dollar is going to weaken, they protect their investments by raising mortgage rates.
Mortgage rates hit their highest point since May last Wednesday, after the U.S. resumed its blockade of Iranian ports the day before.
Even with these new inflation concerns, futures traders don't expect the Fed to raise the federal funds rate (which also typically drives up mortgage rates) at its July meeting. However, odds of a rate hike are currently over 50% for September, according to CME FedWatch.

🔁 Should I refinance?
Refinancing might make sense if today’s rates are at least 0.5 to 0.75 of a percentage point lower than your current rate (and if you plan to stay in your home long enough to break even on closing costs).
With rates where they are right now, you may want to start considering a refi if your current rate is around 6.98% or higher.
Also consider your goals: Are you trying to lower your monthly payment, shorten your loan term or turn home equity into cash? For example, you might be more comfortable with paying a higher rate for a cash-out refinance than you would for a rate-and-term refinance, so long as the overall costs are lower than if you kept your original mortgage and added a HELOC or home equity loan.
If you're looking for a lower rate, use NerdWallet's refinance calculator to estimate savings and understand how long it would take to break even on the costs of refinancing.

🏡 Should I start shopping for a home?
There is no universal “right” time to start shopping — what matters is whether you can comfortably afford a mortgage now at today’s rates.
If the answer is yes, don’t get too hung up on whether you could be missing out on lower rates later; you can refinance down the road. Focus on getting preapproved, comparing lender offers, and understanding what monthly payment works for your budget.
NerdWallet’s affordability calculator can help you estimate your potential monthly payment. If a new home isn’t in the cards right now, there are still things you can do to strengthen your buyer profile. Take this time to pay down existing debts and build your down payment savings. Not only will this free up more cash flow for a future mortgage payment, it can also get you a better interest rate when you’re ready to buy.

🔒 Should I lock my rate?
If you already have a quote you’re happy with, you should consider locking your mortgage rate, especially if your lender offers a float-down option. A float-down lets you take advantage of a better rate if the market drops during your lock period.
Rate locks protect you from increases while your loan is processed, and with the market forever bouncing around, that peace of mind can be worth it.
🤓 Nerdy Reminder: Rates can change daily, and even hourly. If you’re happy with the deal you have, it’s okay to commit.

🧐 Why is the rate I saw online different from the quote I got?
The rate you see advertised is a sample rate — usually for a borrower with perfect credit, making a big down payment, and paying for mortgage points. That won't match every buyer's circumstances.
In addition to market factors outside of your control, your customized quote depends on your:
- Credit score
- Debt-to-income ratio
- Employment history
- Down payment
- Type of mortgage
- Location and property type
- Loan amount
Even two people with similar credit scores might get different rates, depending on their overall financial profiles.

👀 If I apply now, can I get the rate I saw today?
Maybe — but even personalized rate quotes can change until you lock. That’s because lenders adjust pricing multiple times a day in response to market changes.
