TL;DR
In Bethesda, the 15-year fixed mortgage rate is currently 5.856% versus 6.911% for a 30-year loan. On an $800,000 loan, the 15-year saves approximately $695,000 in total interest — but costs about $1,415 more per month. Most high-income Bethesda buyers with stable cash flow choose the 15-year for the interest savings; buyers who value flexibility or plan to invest the difference often choose the 30-year. The right answer depends on your income stability, how long you plan to stay, and what you’d actually do with that $1,415 each month.

One of the most common questions I hear from buyers in Bethesda and Potomac right now is some version of: “Should I go 15 or 30 years?”
It sounds like a simple math problem. It’s not. The right answer depends on your income, your investment strategy, how long you’re staying in the home, and whether you’d actually do something productive with the monthly savings from the 30-year option.
Let’s run the real numbers and work through which one makes sense for your situation.
The Rate Gap Right Now
As of May 2026, here’s what buyers in Bethesda are looking at:
- 30-year fixed: 6.911%
- 15-year fixed: 5.856%
That’s a 1.055-percentage-point spread. On smaller loan amounts, that gap is meaningful but manageable. On the loan amounts typical in Bethesda — where the median home price sits around $1.2 million — it adds up fast.
Let’s use $800,000 as our loan example (roughly 20% down on a $1 million home, which is on the lower end for Bethesda):
- 30-year at 6.911%: approximately $5,275/month in principal and interest — $1,099,000 in total interest over 30 years
- 15-year at 5.856%: approximately $6,690/month in principal and interest — $404,200 in total interest over 15 years
The 15-year buyer pays about $1,415 more per month — and saves roughly $695,000 in interest over the life of the loan.
That’s not a rounding error. For many buyers, that $695,000 figure is the most compelling part of the 15-year case.
Why Most Bethesda Buyers Still Choose the 30-Year
Here’s what I see in practice: the majority of high-income buyers in Bethesda, Potomac, and Chevy Chase choose the 30-year — even when they could comfortably qualify for the 15-year payment.
The reasons are real.
Cash flow flexibility matters at this price point. When your mortgage payment alone is $5,000–$7,000 per month on a conforming loan — or $7,000–$9,000 on a jumbo — the lower required payment of the 30-year gives you breathing room. If your income dips, if you have a large expense year, or if you want to redirect cash toward retirement accounts or other investments, you still have options. The 15-year locks you into that higher payment regardless of what life throws at you.
Montgomery County property taxes add up. Beyond your P&I payment, property taxes in Montgomery County on a $1.2M home run roughly $12,000–$14,000 per year — about $1,000–$1,170 per month. Add homeowner’s insurance, any HOA fees, and utilities, and the total monthly cost of owning a home in Bethesda can reach $7,500–$10,000+ on a 30-year loan, and $9,000–$12,000+ on a 15-year. That context matters when you’re deciding how much payment to commit to.
The investment argument has real merit — if you actually invest the difference. If you take the $1,415/month saved by choosing a 30-year mortgage and consistently invest it in assets returning more than 5.856%, you could theoretically come out ahead compared to paying down a 5.856% mortgage early. The problem is that most buyers don’t maintain that discipline for 30 years. If you’re confident in your investment strategy and committed to executing it, the argument holds. If you’re not, the 15-year’s forced savings tend to outperform undisciplined discretionary investing.
When the 15-Year Makes Clear Sense
The 15-year tends to be the right call when several of these apply:
- Your income is high and stable, and the higher payment represents 25–30% or less of your gross monthly income
- You’re in your 40s or 50s and want the mortgage paid off before or near retirement
- You know you’ll be in the home for 10+ years — enough time to benefit from the accelerated equity buildup
- You want the discipline of forced savings without relying on consistent investing behavior
- You’re risk-averse and prefer the certainty of a paid-off home over the theoretical upside of investing the difference
The equity buildup difference is dramatic. In year one of a 30-year at 6.911%, about 81% of your $5,275 payment goes to interest. On a 15-year at 5.856%, roughly 70% goes to interest — and that ratio improves much faster as the loan pays down. By year five, your equity position on the 15-year is substantially stronger, which matters if you plan to sell, refinance, or access a home equity line.
The Hybrid Strategy: 30-Year with Voluntary Extra Payments
There’s a third path that many Bethesda buyers take: the 30-year loan with a disciplined extra payment strategy.
Making just one extra principal payment per year on a 30-year mortgage can reduce your payoff timeline by roughly 4–6 years and save a meaningful amount in interest — without locking you into the higher required payment every month. If you make consistent overpayments approaching the 15-year payment level, you can effectively pay the loan off in 15–18 years while retaining the flexibility to pull back in tough months.
The tradeoff is real: you’re paying the higher 30-year rate (6.911% vs. 5.856%) on whatever balance remains, so you’re not capturing the full interest savings of a true 15-year loan. But the flexibility can be worth that cost — especially for buyers in Bethesda’s price range who are managing multiple financial priorities simultaneously.
The Jumbo Loan Wrinkle
Here’s something every Bethesda buyer should factor in: the 2026 conforming loan limit in Montgomery County is $1,209,750. Any loan above that threshold is a jumbo loan — regardless of whether you choose a 15- or 30-year term.
Jumbo loan pricing can differ meaningfully from conforming loan pricing, and the 15-vs-30-year rate spread isn’t always the same in the jumbo market. On a $1.5M purchase with 20% down, your loan is $1.2M — just below the conforming limit. On a $2M purchase with 20% down, your $1.6M loan is well into jumbo territory, where you should comparison-shop lenders specifically on term pricing.
If your loan amount is near or above $1.2M, get quotes on both terms from multiple lenders before deciding. Don’t assume the spread you see on a rate-comparison site reflects what you’ll actually be offered on your specific loan amount and credit profile.

A Quick Framework for the Decision
Here’s the shortcut I use with buyers:
If the 15-year payment is 28–30% or less of your gross monthly income and your emergency reserves are solid, the 15-year is usually the smarter financial move. You’re locking in a lower rate, building equity fast, and avoiding nearly $700,000 in interest.
If the 15-year payment pushes your housing cost above 35% of gross income — or if qualifying for the 15-year requires stretching reserves thin — the 30-year is the right call. Cash flow flexibility matters, and you can always pay extra. You can’t take back a month where the higher payment created real financial stress.
And if you’re not sure where you land? Run both scenarios with your lender before you’re under contract. Knowing your numbers before you make an offer is one of the most underrated advantages a buyer in a competitive market like Bethesda can have.

Frequently Asked Questions

As of May 2026, the 15-year fixed mortgage rate in Bethesda is approximately 5.856%, compared to 6.911% for a 30-year fixed loan. Rates vary by lender, credit score, and loan size — jumbo loans above the Montgomery County conforming limit of $1,209,750 may carry slightly different pricing.
How much do I save in interest with a 15-year vs. 30-year mortgage?
On an $800,000 loan at current Bethesda rates (5.856% for 15-year vs. 6.911% for 30-year), the 15-year mortgage saves approximately $695,000 in total interest over the life of the loan. The tradeoff is a monthly payment about $1,415 higher than the 30-year equivalent.
Is a 15-year mortgage a good idea for Bethesda buyers?
A 15-year mortgage makes the most sense for Bethesda buyers with high, stable income who plan to stay in the home long-term and want to minimize total interest paid. Buyers who value cash flow flexibility, plan to invest the payment difference, or anticipate job or lifestyle changes typically do better with the 30-year option.
Can I make extra payments on a 30-year mortgage to pay it off faster?
Yes — and this is one of the most popular strategies for Bethesda buyers who want the flexibility of a 30-year payment but want to pay down the loan faster. Making one extra principal payment per year on a 30-year loan can reduce the payoff timeline by roughly 4–6 years and save tens of thousands in interest, without the obligation of a higher required payment each month.
Does the loan term affect whether I need a jumbo loan in Bethesda?
The loan term (15-year vs. 30-year) doesn’t affect the jumbo threshold. In Montgomery County, the 2026 conforming loan limit is $1,209,750. Any loan above that amount is a jumbo loan regardless of term length — and jumbo loans may carry different interest rates and qualification requirements than conforming loans.
The 15-year versus 30-year decision isn’t just about rates — it’s about your income, your timeline, and what you’d actually do with the payment difference. In Bethesda’s price range, getting that choice wrong can cost you hundreds of thousands of dollars in either direction.
