Old Town, Del Ray or Rosemont: How to Choose a Condo Neighborhood

Updated October 2026

You've narrowed it to three. Old Town, Del Ray, Rosemont. They sit within a few minutes of each other, and every one of them has history, sidewalks, and somewhere good to get coffee.

So why does the choice feel so hard?

Because the differences that matter most to a condo owner don't show up in a listing photo. They show up later, when you want to change a window, catch a bus, or figure out which school your address is zoned for. Here's how the three compare, plus where we'd lean based on what we see every week.

The short answer

Old Town sits inside the Old & Historic Alexandria District, a locally regulated district where exterior changes visible from a public way need city approval. It has the free King Street Trolley at its center.

Del Ray grew from two subdivisions that became the Town of Potomac, now a National Register historic district, with Mount Vernon Avenue as its main street and DASH Line 33 running through it.

Rosemont is a National Register historic district next to Alexandria's Union Station, described by the city as an early-twentieth century trolley suburb.

National Register listing and local design review are not the same thing. That one distinction shapes more condo decisions than most buyers expect.

Old Town: the city's locally regulated core

According to the City of Alexandria, the Old & Historic Alexandria District is "the third oldest historic district in the United States (established in 1946)." The city's Board of Architectural Review is "charged with approving a Certificate of Appropriateness for all new construction and exterior alterations for structures designated as visible from a public way," as the city's historic preservation page puts it.

For a condo owner, that review usually runs through your association rather than through you. Windows, doors, railings, rooftop equipment: if it's on the outside and visible from the street, the building's board and the city both have a say. That's worth asking about before you write an offer, especially in an older conversion.

Getting around is simple. DASH says the King Street Trolley runs every 15 minutes from 11 AM to 11 PM, 365 days a year, between the King Street-Old Town Metro and City Hall/Market Square. It's free.

In our experience, Old Town's condo stock runs from converted historic buildings to newer elevator buildings, and the trade-offs between them are real. Our Old Town Alexandria condo guide walks through those building types. If you'll have a car, read the Old Town Alexandria parking guide before you fall for a building without a garage.

Del Ray: a main street town that became a neighborhood

The City of Alexandria's National Register page explains the origin plainly: "St. Elmo and Del Ray, two subdivisions platted in 1894, were joined together in 1908 to form the incorporated town of Potomac." That town is now listed on the National Register as the Town of Potomac historic district.

Mount Vernon Avenue is the spine. In our experience, most of daily life in Del Ray happens within a few blocks of it.

For transit, DASH's schedules page lists Line 33 running King St Metro to Commonwealth Ave, Mt Vernon Ave, and Potomac Yard Metro every 30 minutes on weekdays from 5AM to 8PM. DASH is fare-free.

In my experience, condo options here tend to be smaller buildings and conversions rather than large towers, so the number of units on the market at any one time can be thin. If Del Ray is your first choice, start watching early. Our Del Ray neighborhood guide has more on the blocks and the Avenue itself.

Rosemont: a trolley suburb by Union Station

The city describes Rosemont as "located northwest of the Old and Historic District of Alexandria, adjacent to Alexandria's Union Station," and calls it "an unusually intact example of an early-twentieth century middle-class trolley suburb." Its early growth, the same page notes, "was closely linked to the growth of the electric rail system in the Washington area." Both quotes come from the city's list of Alexandria sites on the National Register of Historic Places.

In my experience, Rosemont's streets are mostly single-family houses. My read is that condo buyers who want Rosemont often end up looking at its edges, closer to King Street and the station, and comparing those buildings against Old Town options a few blocks away.

Historic rules, side by side

This is where buyers get tripped up. All three neighborhoods carry "historic" in their descriptions, but the rules work differently.

The City of Alexandria notes that "the boundaries of the local districts differ from those of the National Register Districts," and that buildings designated by City Council ordinance as One Hundred Year Old Buildings are regulated by the Board of Architectural Review. So a specific address matters more than the neighborhood name. The city's Historic Preservation Map viewer is the place to check a property before you plan any exterior work.

Getting around without a car

In our experience, all three neighborhoods work for a car-light life, in different ways.

• Old Town: the free King Street Trolley along King Street, plus the King Street-Old Town Metro at one end of the trolley route.
• Del Ray: DASH Line 33 along Mount Vernon Avenue, connecting King St Metro and Potomac Yard Metro.
• Rosemont: the city places it adjacent to Alexandria's Union Station, with King Street along one edge of the historic district.

Commute times depend on the exact block and where you're headed. We'd rather walk the route with you than quote one.

Schools: check the address, not the neighborhood

Alexandria City Public Schools adopted new attendance boundaries that took effect July 1, 2026, for the 2026-27 school year. According to ACPS, approximately 1,400 currently enrolled students are affected.

That means a school assignment you heard from a neighbor, or read in an older article, may be out of date. Look up the specific address in the ACPS attendance zone locator before you rely on it. Our post on Del Ray schools and family life explains why we start with the address every time.

What the August numbers show, and what they don't

A clean price ranking of the three neighborhoods doesn't exist. The closest thing is ZIP code data.

According to our analysis of Bright MLS closed-sale data, the 22301 ZIP code, which includes Del Ray and Rosemont, recorded 13 closed residential sales in August 2026, compared with 16 in August 2025. The median sale price across those 13 sales was $886,700, against $928,000 a year earlier. Median days on market was 5 days in August 2026 and 7 days in August 2025.

Chart 1. Median sale price, all residential, ZIP code 22301. Source: Bright MLS closed-sale data, Alexandria 22301, August 2025 and August 2026, pulled September 27, 2026.
The bars show a lower median in August 2026 than in August 2025. Read that carefully. With this few sales, one or two larger houses closing in a given month can move the median on its own, and these figures mix condos, townhouses, and detached homes. They don't separate Del Ray from Rosemont, and they don't describe Old Town at all.

Figures are our analysis of individual Bright MLS closed-sale records for all residential property types in ZIP code 22301, Alexandria City. They are not statistics published by Bright MLS, and a ZIP code is not the same as a neighborhood.

The wider region gives some context. The Northern Virginia Association of REALTORS® reported 3,025 active listings across its region in August 2026, up 19.6% from August 2025, and months of supply of 2.13, up 14.8%. That region covers Fairfax and Arlington counties and the cities of Alexandria, Fairfax, and Falls Church, among other areas, so it's a regional picture, not a neighborhood one. NVAR's August 2026 market statistics have the full release.

My read: more listings across the region generally means more to compare, and that's a better position for a buyer than the opposite. It doesn't tell you how much room there is on any one condo in any one building.

How we'd choose

This part is opinion, built from years of walking these blocks with clients.

Start with the building, then the neighborhood. For a condo, the association's finances, rules, and upcoming projects can matter as much as the street. Ask for the resale packet early and read it. Our guide to Alexandria condo fees and resale packets covers what to look for.

Ask who approves exterior work. In Old Town, assume the Board of Architectural Review is part of the picture. In Del Ray and Rosemont, check whether the building is a designated One Hundred Year Old Building.

Live a weekday in each one. Ride the trolley at lunch. Catch Line 33 at rush hour. Walk from Rosemont to Union Station in the rain. You'll know.

Look up the school by address, even if you don't have children. In my experience, the next buyer will ask.
