The Park Loggia (15 West 61 Street)
1. BUILDING OVERVIEW (ANALYST FRAMING)
The Park Loggia (15 West 61 Street) is a recent development condo completed in 2019, located in the Lincoln Square sub-neighborhood of the Upper West Side. This 32-floor, 172-unit asset functions as a high-velocity pricing benchmark, outperforming Lincoln Square by 61.5% in median PPSF. Based on post-sponsor trading patterns, the building is classified as a Hybrid asset. It exhibits the pricing power of an appreciation-driven asset but is currently struggling with a significant liquidity shift in its resale market, where marketing periods are stretching far beyond initial sponsor tranches. While its nominal rent efficiency is elite, it suffers from acute income leakage during absorption. Pricing behavior remains sensitive to the NYXRCSA Oct 2025 benchmark (331.14) as it transitions from sponsor-led growth to a resale-driven regime.
2. UNIT MIX & COMPOSITION
The unit mix is transaction-weighted, inferred from 182 sales and 89 rentals.
Unit Type | Sale activity | % of Sales Activity | Impact on Performance |
Studio | 10 | 5.5% | Secondary liquidity; 163-day median DOM. |
1 Bedroom | 80 | 44.0% | Primary building engine; anchors core volume. |
2 Bedroom | 60 | 33.0% | Core value segment; exhibits 184–388 day friction. |
3 Bedroom+ | 28 | 15.4% | Prestige segment; defines PPSF ceiling ($3,300+). |
Other | 4 | 2.1% | Specialty tranches. |
Analysis: The building is 1-bedroom dominant, which supports baseline transaction volume. However, a significant unit size / unit mix imbalance is emerging in the 2-bedroom and 3-bedroom tiers, where marketing periods (184–320 days) are nearly double the building's initial expectations, leading to a median building-wide discount of 4.84% from original ask.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
Sponsor Normalization Disclosure: Following the B³ rule, 126 transactions occurring between February 2019 and February 2024 (e.g., Units 8F, 3N, 5A, 19C, 17A, 5D, 26A, 5L, 4M, 6M, 16C, 14E, PH1B, 30B, 3K, 11E, 20B, PH2B, 30C, 17B, 3B, 9E, 8E, 28A, 4G, 22B, 24A, 3C, 24C, 9C, 8C, 4C, 19B, 9A, 4J, 6D, 5I, 27A, 28A, 5C, 9F, 14D, 12D, 11C, 16D, 23C, 12F, 26B, 24B, 19D, 6E, 18C, 4F, 5E, 4E, 3F, 6F, 4I, 29B, 15C, 8G, 11G, 9D, 27B, 3E, 22A, PH32C, 28B, 5M, 9G, 5G, 27C, 30D, 12G, 17D, 17C, 25C, PH1A, 14G, 15A, 12B, 6K, 4L, 18D, 25A, 28D, 23A, PH2A, 6O, 22D, 24D, 5J, 10F, 23D, 27D, 6H, 6B, 15C, 12A, 3M, 8B, 16E, 10D, 4H, 4K, 3H, 10E, 14A, 5K, 10G, 11A, 29C, 26D, 16A, 6L, 21D, 6N, 29A, 14B, 10B, 29D, 9B, 11B, 28C) are reclassified as sponsor-driven or conversion tranches.
Impact: Normalization removes the artificial "zero-day" floor, revealing a realistic resale median DOM of 181 days, significantly higher than the initial "No Listing" tranches.
A. Liquidity (Resale Only):
Fastest Units: The 1BR/1BA segment (Line G, M) clears most efficiently with a median of 95 days.
Slowest Units: The 2BR/2.5BA segment (Line O, N) and 3BR+ combination units act as chronic bottlenecks, with median marketing periods of 388 to 587 days.
B. Price Strength: The building's median resale PPSF is $2,467.
Structural Premiums: Penthouse lines and high-floor A-lines (3BR/2.5BA) command elite premiums, clearing between $3,343 and $4,016 PPSF.
Structural Discounts: Studio and lower-floor 1BR units (e.g., 16D, 3D, 4D) trade at structural discounts, frequently clearing between $1,520 and $1,842 PPSF.
4. BUILDING-WIDE PPSF TREND (NORMALIZED)
2019–2021 (Sponsor Baseline): PPSF established between $2,100 and $2,600 for core residences.
2022–2023 (Expansion): Values peaked with PH sales reaching $4,016 PPSF.
2024–2025 (Current Regime): Recent resales show mean-reversion, with pricing stabilizing between $2,288 and $2,879 PPSF.
Conclusion: Cyclical/Mean-Reverting. Resale pairs indicate that most units are currently trading slightly below or flat relative to their 2021–2022 peaks.
5. RENT CAPTURE ANALYSIS
MANDATORY FORMULA: Effective Annual Rent = Achieved Rent × (365 − Rental DOM) ÷ 365.
Unit | Achieved Rent | Rental DOM | Effective Annual Rent | Rent Leakage |
12G (1BR) | $8,500 | 20 | $97,438 | $4,562 (4.5%) |
17A (3BR) | $18,000 | 141 | $132,559 | $83,441 (38.6%) |
9F (2BR) | $10,000 | 185 | $59,178 | $60,822 (50.7%) |
14A (3BR) | $14,950 | 444 | $0 (Loss) | $179,400 (100%+) |
Analysis: Income capture is efficient in low-DOM 1-bedroom units like 12G. However, the building suffers from catastrophic income leakage (38%–100%) in 2-bedroom and 3-bedroom stacks where absorption friction exceeds 140 days, effectively erasing over a year of potential revenue.
6. B³ SCORING SYSTEM (0–100)
Liquidity Score: 55/100 — Supported by 1BR volume but penalized by the 181-day median DOM and extreme 1,192-day outliers.
Rent Capture Score: 60/100 — Driven by high nominal PPSF ($120+) offset by catastrophic vacancy leakage in multiple years.
Appreciation Score: 62/100 — Reflects early compounding from 2019 baselines, though recent pairs show pricing stagnation or mild drawdowns.
7. COMPOSITE SCORE & CLASSIFICATION
Composite Score = (55 × 0.35) + (60 × 0.30) + (62 × 0.35) = 58.95
Category: Hybrid The Park Loggia qualifies as a Hybrid asset, functioning as a high-value capital store that currently lacks the liquidity and rent capture efficiency of a Core/Defensive asset.
8. TRANSACTION EXAMPLES
Resale Depreciation/Stagnation Examples:
Unit 10A (3BR): $3,169 PPSF (2021) → $3,072 PPSF (2024). -3.1% Total. Driver: (1) Market regime timing.
Unit 27C (1BR): $2,467 PPSF (2020) → $2,368 PPSF (2025). -4.0% Total. Driver: (1) Market regime timing.
Unit 22B (2BR): $2,966 PPSF (2021) → $2,879 PPSF (2024). -2.9% Total. Driver: (1) Market regime timing.
Unit 15B (2BR): $2,811 PPSF (2024) at 1,192 DOM. Driver: (3) Liquidity shift.
9. RISKS & RED FLAGS
Chronic Liquidity Friction: Avoid the 15B, 4O, and 6A stacks for short-term holds; resale marketing periods exceeding 490 to 1,190 days signal severe exit friction.
Catastrophic Rent Leakage: 3-bedroom rentals (e.g., Line A) are prone to absorption failures where DOM exceeds 440 days, decimating annual yields.
High Original Ask Friction: Larger units (4BR) clear at a 16.27% discount from original ask, signaling significant pricing discovery gaps.
10. EXECUTIVE SUMMARY
The Park Loggia is a Hybrid recent development that functions as a premier pricing anchor in Lincoln Square, outperforming the sub-neighborhood by over 61%. Post-sponsor behavior is characterized by a pronounced liquidity shift, where true resale marketing periods have stretched to a median of 181 days, with extreme outliers reaching nearly three years. While the building commands elite nominal rents, its income capture is highly unstable, with vacancy leakage exceeding 50% in the 2-bedroom and 3-bedroom core. Opportunity lies in the high-velocity 1-bedroom segment for consistent yield, while risk is concentrated in the larger residences where exit friction and yield erosion are acute.
