Twenty homes closed inside the walls of Old San Juan between January and October 2026. They ran from $325,000 to $2,500,000, with a median of $594,000. Five cleared a million dollars. Sellers took 91 percent of what they first asked, after a median of 75 days. Eight of the twenty were cash.
The twelve highest asking prices, each checked against its own listing on 26 October 2026. What the street actually closed for is below.
Every closing below is from the MLS, sorted by price. The percentage is against the original asking price, not a reduced one.

311 Fortaleza is a commercial unit and the MLS does not record its square footage, so it carries no rate. 403 Calle Luna carries neither: it was entered into the MLS after the deal was agreed.
The median price in Old San Juan in 2026 was $594,000. That is a modest number next to Dorado or Condado, and it is the wrong number to read the market by. The median rate was $606 a square foot.
Held against the communities we track on this site, over the same window:
Community | Median $/ft², 2026 |
Condado | $630 |
Old San Juan | $606 |
Isla Verde | $464 |
Los Paseos, Dorado | $274 |
Guaynabo | $271 |
Old San Juan clears within four percent of Condado's rate. The entry price is lower because the units are smaller, not because the ground is worth less.
323 Recinto Sur closed at $1,080 a square foot. 206 Calle Luna closed at $129. Both are in Old San Juan. The two addresses are a short walk apart.
206 Luna is the reason the spread exists: 3,927 square feet, unrestored, $505,000, and it closed at 101 percent of its asking price in four days. Restoration status moves the rate by a factor of eight here. In Old San Juan the building's condition is the price, and the street is close to secondary.
Eighty-five closings between October 2023 and October 2026. From $300,000 to $5,250,000, median $820,000. Rates from $129 to $1,080 a square foot, median $569. Thirty-two of the eighty-five cleared a million dollars. Sellers took 92 percent of their first ask, after 82 days. Sales that were already agreed before the listing went up are left out of this figure.
By year: 24 in 2024, 38 in 2025, 20 through October 2026.
By type: 52 condominiums, 28 single-family houses, two triplexes, one townhouse, one mixed-use building and one commercial unit.
The highest of the thirty-six months: 204 Calle Tetuán at $5,250,000 for 12,535 square feet, $419 a foot. 58 Calle San Justo at $3,800,000, 8,600 square feet, $442, at 100 percent of ask and zero days on market. 323 Recinto Sur at $2,700,000. Then 275 Calle Sol at $2,685,000, 282 Calle Sol at $2,600,000, 14 Calle Sol at $2,525,000, 403 Calle Luna at $2,500,000 and 150 Calle San Justo at $2,500,000.
Sixty-five percent of everything that closed in Old San Juan over three years closed without a mortgage.
It does not show up in the days on market the way it looks like it does. Three of the sales above are recorded at 100 percent of ask with zero days on market: 403 Calle Luna at $2,500,000, 58 Calle San Justo at $3,800,000 and 150 Calle San Justo at $2,500,000. All three went into the MLS after the deal was agreed, so they are left out of the 82-day median above.
The other side of that figure matters just as much. 51 Calle Cristo sold three separate units in 2026, at 89, 79 and 69 percent of their first asking prices, after 122, 216 and 216 days. Three units, same building, same year. What they asked decided what they got.
These are closed sales, not a valuation. What a particular building is worth inside the walls depends on its restoration, its structure, its permits and its floor — the figures above set the range, and the comparables are chosen in a CMA.
