By the Numbers: Sean Mamola's San Francisco Condo Track Record (2018–2026)

When you're choosing a real estate agent in San Francisco, marketing language only gets you so far. What actually matters is the track record: How many homes has this agent sold? In what neighborhoods and price ranges? And do their sellers get strong prices? This post lays out Sean Mamola's performance using verified San Francisco MLS data, benchmarked against the wider market.

All figures below come from San Francisco Association of REALTORS® (SFAR) MLS closed-transaction records. Market comparisons are drawn from 2,569 SF residential sales that closed between December 2025 and June 2026.

The Snapshot

Across 2018 through 2026, Sean Mamola has closed 52 transactions totaling more than $76.7 million in sales volume, working everywhere from a $340,000 condo to an $8.7 million luxury residence. He remains highly active, with 17 closings in 2025–2026 alone.

*Benchmark = 2,569 SF residential closed sales, Dec 2025–June 2026 (SFAR MLS).

A Genuine San Francisco Condo Specialist

The headline takeaway from the data is focus. 92% of Sean's career sales — 48 of 52 — are condominiums. That matters because condos are the most technically demanding part of the San Francisco market: HOA documentation, financing nuances, and tight pricing bands all require specialized experience. As a Global Luxury Specialist with Compass and Rises.co, Sean concentrates on exactly this segment, including high-rise condos, penthouses, and full-amenity buildings.

That specialization shows up in the numbers. On a price-per-square-foot basis — the metric sophisticated buyers and sellers actually compare — Sean's condo sales average $1,143 per square foot, above the $1,126 market average. In a market where value is measured by the foot, he consistently extracts top-of-range results.

Strong Prices, Efficient Sales

Two more data points round out the picture:

Half of Sean's listings sell at or above asking price. That's a function of accurate pricing and disciplined negotiation, not chance — and it's backed by standout individual results (below).

His listings sell quickly. The median time on market is roughly 17 days — most homes go pending in under three weeks, and several have closed in 3 to 7 days.

Methodology: All figures are derived from San Francisco Association of REALTORS® (SFAR) MLS closed-transaction records. Sean's performance reflects 52 closed transactions (2018–2026). Market benchmarks reflect 2,569 SF residential closed sales from December 2025 through June 2026. Per-square-foot and days-on-market comparisons are segmented by property type (condominium vs. single-family), since deliberately underpriced single-family listings inflate citywide over-asking averages. All metrics are verifiable against MLS records.
