Mortgage Rate Outlook for Fall 2026: What the September Fed Increase Means in DC

The Federal Reserve raised its target rate on September 16, 2026, and mortgage rates rose with it. This post covers what changed and what to do about it on a DC purchase or refinance.

What changed in September 2026

  • The Fed raised its target rate. On September 16 the Federal Open Market Committee lifted the federal funds target range a quarter point to 3.75–4.00%, its first increase in more than three years, on a unanimous vote. Its statement: "Inflation remains elevated." (Federal Reserve)
  • Mortgage rates rose. Freddie Mac's national survey showed the 30-year fixed average higher for the week of September 17 than the week before and higher than a year earlier. (Freddie Mac PMMS)
  • The 10-year Treasury moved above 5% (Treasury daily yield curve), pushed up by higher oil prices feeding inflation, heavy federal borrowing, and the Fed's move to raising rates.
  • The Fed may raise again this year. The Fed's own projections put the median funds rate at 4.1% at year end (central tendency 4.1–4.4%), which leaves room for another increase at the October or December meeting.

Freddie Mac's survey is a national average. Today's DC pricing is on our rates page.

Why mortgage rates follow the 10-year Treasury

Mortgage rates follow the 10-year Treasury yield more closely than the federal funds rate. The 10-year yield rose this year on persistent inflation and heavy Treasury borrowing, and mortgage rates rose with it. A Fed pause or cut will not lower 30-year fixed rates until the 10-year yield comes down. Watch the 10-year yield and the monthly inflation reports.

Steps for DC home buyers

  • Qualify at today's rate. A pre-qualification based on current pricing tells you what you can close on. If rates fall later, you can refinance.
  • Ask the seller for a closing-cost credit or a temporary buydown. A seller can pay your closing costs or fund a temporary buydown. A seller credit applied to a buydown lowers your payments in the first two years by more than the same dollars taken off the price.
  • Fannie Mae and Freddie Mac waive pricing adjustments for first-time buyers at or below 120% of area median income. Fannie Mae and Freddie Mac waive their loan-level pricing adjustments for first-time buyers with income at or below 120% of area median income, and DC counts as a high-cost area. The mechanics are in our Capitol Hill rowhouse guide.
  • Check whether your loan is standard conforming or high-balance. Loans up to $832,750 price as standard conforming; DC's high-cost ceiling is $1,249,125, and loans in between price as high-balance. The tier changes both the rate and the minimum down payment.

Steps for DC homeowners

  • If your first mortgage is from 2020–2021, keep it in place. Replacing a low first mortgage with a cash-out refinance reprices the whole balance at today's rates. A home equity loan or line of credit as a second lien leaves the first alone. Start with our equity options for long-time DC owners.
  • DC charges no recordation tax on a residential refinance. With the ROD 21 affidavit, a refinance or second lien on a home of five or fewer units is exempt from DC recordation tax under D.C. Code § 42-1102(21). Details in the cash-out guide.
  • If you bought in 2023–2025, set a refinance target rate. A rate-and-term refinance depends on the 10-year yield coming down. Tell us your target rate and we will tell you when the market reaches it. The refinance savings tool shows what a given drop would be worth on your loan.

Reports that could move mortgage rates this fall

Lower inflation reports, falling oil prices, or a weak jobs report would pull the 10-year yield down, and mortgage rates with it. A high inflation report or a second Fed increase would push both up. Our rates page shows the date of each update, so you can see DC pricing on any given day.
