Upper Northwest DC Market Update: Prices Didn't Fall in September. The Market Split.

by Sherine Monir

Did home prices fall in Upper Northwest DC in September?

No. The median sale price for a detached house in Upper Northwest DC dropped from $2,510,000 in August to $1,768,888 in September, but that drop came from a change in which homes closed, not from homes losing value. In August, 18 houses sold for $3 million or more. In September, only 5 did. Sellers still received a median 97.5% of their original asking price, almost the same as August's 98.6%.

The real story of September is a market split in two. Houses that went under contract within 10 days sold at full asking price. Houses that sat for more than a month closed at a median 89.1% of their original price. This update covers detached single-family houses in the four ZIP codes that make up most of Upper Northwest DC: 20016, 20008, 20015 and 20007. That takes in Spring Valley, Wesley Heights, American University Park, Chevy Chase, Cleveland Park, Forest Hills, Georgetown and the neighborhoods around them.

The September Numbers

These figures come from Bright MLS closed sales records for detached single-family houses that settled between August 1 and September 30, 2026. As in every update, each sale is measured against the seller's original asking price, not a reduced price, and days on market count the full time a house was listed, including any relistings.

Why the Median Dropped $740,000

A median is the middle sale on the list. When the list changes, the middle changes with it. August was heavy with luxury closings in Spring Valley, Kent and Wesley Heights, and nearly half of that month's sales were at $3 million or more. September had far more houses in the $1 million to $1.5 million range, so the middle of the list moved down.

The better measure of what sellers actually received is the sale price compared with the original asking price. That number moved by about one point, from 98.6% to 97.5%. That is a steady market, not a falling one. I explain the same effect over a longer period in my Upper Northwest DC housing market overview, and you can compare it with the June market update.

The First Ten Days Decided the Price

Behind the 97.5% are two very different groups of sellers. I split every September sale by how long it took to go under contract.

Time on market August houses August median share of original asking September houses September median share of original asking
10 days or fewer 18 100.0% 14 100.0%
More than 30 days 15 93.9% 15 89.1%

In September, the gap between those groups was about 11 points. On a $1.5 million house, that is more than $160,000. The gap also widened from August, when the slower houses still closed at about 94% of their first price.

The examples below are rounded so no single sale can be identified.

  • A bungalow in American University Park, priced around $1 million, sold about 14% over asking without ever sitting on the market.
  • A Tudor in Chevy Chase, priced in the upper $1 millions, went under contract in about a week and closed roughly 10% over asking.
  • A house in North Cleveland Park, priced in the low $1 millions, sold in about a week for 5% over asking.
  • A house in Cleveland Park that first came on the market in the mid $3 millions sat for more than four months and closed about 26% below its original price.
  • A house in Forest Hills that started in the low $2 millions sat about three months and closed roughly 21% under.
  • In Chevy Chase, several houses that came on in the spring and sat through the summer closed between 13% and 20% below their first asking price.

In almost every case, the difference was the first price. Buyers in Upper Northwest DC know the recent sales. When a house is priced right on the first day, they move quickly and sometimes compete. When it comes on too high, they don't make a low offer. They wait, and each week the house sits, the seller loses negotiating power. I go deeper on this in whether to price below market value.

Where Houses Moved Fastest, and Slowest

September sale price Houses sold Median days on market Median share of original asking
$1 million to $1.5 million 12 8 99.6%
$2 million to $3 million 7 87 95.8%

The fastest range was not the bottom of the market. It was $1 million to $1.5 million, where the typical house went under contract in eight days at close to full price. The slowest was $2 million to $3 million, where the typical house took close to three months.

If your house is likely to sell above $2 million, the bar is higher. Condition, presentation and price all need to be right from the first weekend. As an interior designer, this is where I see preparation pay for itself. My guides to selling as-is or renovating first and when a kitchen renovation is worth it before selling cover which projects make sense.

Detached Houses Under $1 Million Are Still Rare

In July, one detached house in these four ZIP codes sold for under $1 million. In August, none did. In September, two did, both just under $1 million, and one of those was a bank-owned sale. If you are a buyer with that budget, you need financing approved and a plan in place before something comes up. My buying guide walks through how to get ready.

Cash Buyers and Mortgage Rates

Mortgage rates are still high. Mortgage News Daily put the average 30-year fixed rate at 7.37% on October 16, 2026. That is a national average, and your own rate depends on your situation.

Rates matter less here than national headlines suggest. Twelve of the 33 September buyers paid cash, more than a third. In August, it was nearly half. A large share of buyers in Upper Northwest DC are not waiting on rates. They are waiting for the right house at the right price.

What September Means for Sellers and Buyers

If you are selling this fall or next spring, your launch price is the most important decision you will make. Base it on the last three months of closed sales for houses like yours, prepare the house before it goes live, and plan for buyers to decide in the first ten days. My guide to deciding whether to sell, the concierge pre-listing approach and the selling guide walk through the steps. For your bottom line, see DC transfer tax for sellers and seller net proceeds, and before you hire an agent, read the questions worth asking a listing agent.

If you are buying, your best negotiating room is with houses that have been on the market for a month or more, especially above $2 million. For a well-priced house between $1 million and $1.5 million, expect to decide within a week. Once you are under contract, what happens after an offer is accepted explains the next steps.
