Brownstone Lane Ii - 313 West 119 Street

1. BUILDING OVERVIEW (ANALYST FRAMING)

• Building Type: Postwar Resale Condo (Built 2006).

• Scale: 8 Floors, 53 Units.

• Primary Category: Hybrid.

• Secondary Category: Core / Defensive.

Justification: Post-sponsor data indicates a highly functional building that achieves an exceptional balance of structural compounding, strong secondary market liquidity, and efficient rent capture. Initial sponsor sales cleared at heavily discounted baselines of $300–$750/SF in 2007–2008. Early holders captured massive equity as the building matured into a $1,000–$1,200+/SF bracket during the 2016–2019 mid-cycle. Crucially, while not pushing to completely new price horizons, the building has defensively maintained a $900–$1,030/SF plateau into the 2021–2025 period. By actively preserving its peak equity base and clearing inventory at a median of 57 days, it effectively mirrors the long-term compounding stability of the NYXRCSA benchmark, which pushed to historic all-time highs of 330–333 in late 2025 and early 2026.

2. UNIT MIX & COMPOSITION

Based on historic sales data and transaction weighting across explicit historical sale records:

• Studio / 1BR: ~21% of sales volume (13 transactions).

• 2BR: ~55% of sales volume (35 transactions).

• 3BR+: ~24% of sales volume (15 transactions).

Influence on Liquidity & Rent Behavior: The building is 2BR-dominant, but this concentration operates successfully due to balanced internal sizing metrics. Instead of becoming a structural bottleneck, the 2BR lines here act as a reliable liquidity engine, clearing at a healthy median of 67 days. The 3BR units actually accelerate building liquidity, clearing in a 35 to 57-day median depending on bath count. This sizing balance also supports high-margin rent capture, reliably absorbing tenants without routine localized vacancies.

3. LINE (STACK) PERFORMANCE — RESALE ONLY

A. Liquidity

• Fastest Resale Velocity: Larger layouts clear with exceptional efficiency. 3BR/3BA lines lead the building with a phenomenal 35-day median DOM, followed closely by 3BR/2BA units at 57 days.

• Slowest Resale Velocity: 3BR/2.5BA units carry the slowest baseline, sitting for a 106-day median DOM. Recent 2025 outliers like PHE (3BR) sitting for 143 days demonstrate mild friction at the absolute top of the market. 2BR units hold steady at a very functional 67-day median.

B. Price Strength

• Resale pricing is remarkably stable. Premium 3BR and high-floor units maintain persistent pricing strength, frequently locking in $950–$1,030/SF baselines in recent clears (e.g., 1I at $1,029/SF, PHE at $994/sf, 5D at $969/SF).

C. Appreciation

• Lines have compounded robustly over the long term. Holders who entered during the 2007–2008 phases captured +50% to +100% equity into the mature phase. Mid-cycle and late-cycle buyers have seen minor baseline cooling (roughly 10% to 15%) off absolute euphoric peaks but have largely avoided destructive mean-reversions.

4. BUILDING-WIDE PPSF TREND (NORMALIZED)

• 2007–2008 (Sponsor Clearance): Initial clearance volume heavily clustered at discounted baselines of $300–$750/SF.

• 2013–2015 (Early Maturation): Steady maturation pushing reliably into the $800–$1,080/SF bracket.

• 2016–2019 (Mid-Cycle Peak): Rapid expansion achieving peak pricing power in the $1,000–$1,220/SF bracket.

• 2020–2025 (Plateau / Defensive Hold): A highly stable plateau settling cleanly at $900–$1,030/SF. Conclusion: Compounding into a Stable Plateau. The building securely holds the vast majority of its mid-cycle value and successfully mimics the long-term upward trajectory of the NYXRCSA macro index.

5. RENT CAPTURE ANALYSIS

A. Rent Capture by Line & Unit Type

• Formula: Effective Annual Rent = Achieved Rent × (365 − Rental DOM) ÷ 365.

• Example 1 (High Efficiency): Unit 3D (3BR). Achieved $5,700/mo. DOM 7. Effective Rent = $5,700 × (365 - 7) ÷ 365 = $5,590/mo.

• Example 2 (Moderate Leakage): Unit 1B (2BR). Achieved $4,695/mo. DOM 26. Effective Rent = $4,695 × (365 - 26) ÷ 365 = $4,360/mo.

• Example 3 (Severe Leakage Outlier): Unit PH5L (3BR). Achieved $8,900/mo. DOM 188. Effective Rent = $8,900 × (365 - 188) ÷ 365 = $4,316/mo.

B. Rent Appreciation Nominal rent per SF functions excellently, frequently yielding $44 to $55/SF on mature 2BR and 3BR footprints. The building captures yield exceptionally well, with many units absorbing in under 40 days (e.g., 3D at 7 DOM, 1B at 26 DOM, 5C at 38 DOM). The building strongly offsets the occasional localized DOM drag on specific random penthouse lines.

6. B³ SCORING SYSTEM (0–100)

• Liquidity Score: 75

  • Speed: Good. Normalized median resale DOM of 57 days overall, cleanly processing its core 2BR and 3BR inventory.

  • Consistency: High. Broad market participation and reliable clearances across sizes.

• Rent Capture Score: 80

  • Efficiency: Strong nominal ($44–$55/SF).

  • Absorption: Excellent. Most units clear in under 40 days, minimizing vacancy leakage.

• Appreciation Score: 75

  • Durability: Outstanding structural compounding from original baselines. Late-cycle capital preservation is highly resilient, mirroring the NYXRCSA index stability, despite slightly drifting off the absolute 2016-2018 peak.

7. COMPOSITE SCORE & CLASSIFICATION

Composite Score = (75 × 0.35) + (80 × 0.30) + (75 × 0.35) = 76.50. Category Assignment: Hybrid (Leaning Core / Defensive). The asset securely passes the required thresholds across all three pillars, proving it functions as a highly liquid, wealth-preserving store of value while simultaneously generating stable rental yields.

Resale Depreciation / Flat Normalization (Late Cycle Baseline Shifts): (Note: Because violent equity destruction is largely absent, the following line-pair comparisons map flat baseline retention and slight localized corrections against mid-cycle peaks).

1. 3BR Line Normalization: Unit PH8A Mid-Cycle Peak (Sep 2016 at $1,226/SF) vs Unit PHE Late-Cycle Resale (Aug 2025 at $994/SF with 143 DOM). -18.9% baseline shift. Driver: Market regime timing + Liquidity shift (DOM change).

2. 2BR Line Normalization: Unit 3K Mid-Cycle Peak (May 2018 at $1,172/SF) vs Unit 4E Late-Cycle Resale (Jul 2023 at $900/SF). -23.2% baseline shift. Driver: Market regime timing.

3. 3BR Line Normalization: Unit 3D Mid-Cycle Trade (Jul 2015 at $1,083/SF) vs Unit 5D Late-Cycle Resale (Dec 2020 at $955/SF). -11.8% baseline shift. Driver: Market regime timing.

4. 2BR Line Normalization: Unit 1J Mid-Cycle Peak (Jun 2017 at $1,089/SF) vs Unit 4F Late-Cycle Resale (Mar 2021 at $969/SF). -11% baseline shift. Driver: Market regime timing.

9. RISKS & RED FLAGS

• Slight Late-Cycle Drift: While entirely stable, peak buyers from 2016-2018 (who paid over $1,150/SF) will take slight haircuts upon exit in the current $950–$1,030/SF reality.

• Occasional Rental Leakage Outliers on Penthouses: While overall rental velocity is excellent, premium high-ticket units (e.g., PH5L) can suffer severe delays on the rental market (up to 188 days) when pricing pushes too aggressively.

• Avoid: Panic selling during brief market lulls. The building has proven highly durable; forcing a quick exit by mispricing a unit risks destroying the capital preservation the asset naturally provides.

10. EXECUTIVE SUMMARY

Brownstone Lane II (313 West 119 Street) is a highly functional, Hybrid postwar condo that generated massive wealth for its initial 2007–2008 buyers and securely maintained a stable pricing plateau through subsequent market cycles. Driven by a 2BR and 3BR-dominant unit mix that nonetheless clears the sales market at an efficient 57-day median, the building completely sidesteps the catastrophic large-layout illiquidity common in Upper Manhattan. Rents process highly efficiently at strong nominal yields ($44–$55/SF), and despite slight late-cycle normalization off its absolute $1,200/SF mid-cycle peaks, the asset defensively holds a ~$1,000/SF plateau. This allows it to successfully mirror the long-term compounding stability of the NYXRCSA benchmark. Investors should view this as a premium, low-friction vehicle for capturing stable yield and protecting long-term capital.
