Liberty House (377 Rector Place)
1. BUILDING OVERVIEW (ANALYST FRAMING)
Liberty House (377 Rector Place) is a mature postwar resale condo built in 1985 in Battery Park City. Standing 27 floors with 238 units, it is a full-service development. Based on post-sponsor behavior and historical transaction depth, the building is classified as a Hybrid asset. It significantly outperforms the Battery Park City sub-neighborhood by 13.5%. Its profile is defined by a high concentration of one-bedroom units that anchor liquidity, balanced by a luxury segment (Penthouses) that introduces significant volatility and "income leakage." The building has demonstrated a consistent compounding trend over two decades, moving from a 2003 baseline of ~$400 PPSF to recent resale peaks exceeding $1,300 PPSF.
2. UNIT MIX & COMPOSITION
The unit mix is transaction-weighted based on 132 sales and 116 rentals.
Unit Type | % of Sales Activity | Median PPSF | Median DOM | Original Discount |
1BR / 1BA | 57.6% | $1,074 | 77 | -5.52% |
2BR / 1BA | 10.6% | $1,298 | 163 | -10.76% |
2BR / 2BA | 8.3% | $1,055 | 164 | -10.53% |
3BR / 3BA | 0.7% | $1,301 | 138 | -5.43% |
4BR+ | 3.0% | $1,288–$1,728 | 226–512 | -27.93% to -35.61% |
Liquidity stability is heavily driven by the 1BR segment, which accounts for the majority of building volume and clears significantly faster than larger units. Volatility is extreme in the 4BR+ segment, which suffers from chronic illiquidity (median 512 days) and massive price discovery gaps (up to 35.6% discounts). The unit mix suggests the building serves as a high-velocity entry point for the neighborhood, but struggles to maintain efficiency in its largest configurations.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
A. Liquidity: Fastest-clearing resale lines include the 'A', 'G', and 'M' stacks. Unit 6A cleared in 22 days, 12G in 38 days, and 6J in 30 days. Slowest-clearing lines include the Penthouse (PHA/PHB) and 'F' stacks, with PHA languishing for 804 days, 25E for 410 days, and 11F for 381 days.
B. Price Strength: The high-floor 'C' and 'F' lines command structural premiums. Unit 26C reached $1,396 PPSF and 18F hit $1,609 PPSF. Structural discounts are found in the 'A' and 'D' lines, with unit 8A trading at $555 PPSF and 8D at $941 PPSF.
C. Appreciation: The building is Compounding. Unit 2H moved from $473 PPSF (2003) to $998 PPSF (2022). Unit 12L moved from $1,332 PPSF (2021) to $1,392 PPSF (2023).
4. BUILDING-WIDE PPSF TREND (NORMALIZED)
2003–2007 (Early Period): Median PPSF established between $402 and $933.
2012–2016 (Growth Period): Pricing stepped into the $1,000–$1,300 band.
2024–2025 (Maturity): Recent transactions established a range of $1,078 to $1,303 PPSF.
Conclusion: Compounding. Despite neighborhood volatility, the building has tripled its floor price over 20 years, outperforming the sub-neighborhood index.
5. RENT CAPTURE ANALYSIS
MANDATORY: Effective Annual Rent = Achieved Rent × (365 − Rental DOM) ÷ 365.
High-Capture (Unit 18A): Rent $5,400, DOM 45. Effective Rent = $4,734.
Mid-Capture (Unit 11A): Rent $5,400, DOM 100. Effective Rent = $3,920.
Leaky (Unit 14G): Rent $6,000, DOM 284. Effective Rent = $1,331.
Extreme Leakage (Unit PHB): Rent $18,000, DOM 162. Effective Rent = $10,011.
Rent efficiency is strong in 1BR lines ($85–$99 Yearly PPSF), but the building is prone to severe income leakage in 2BR and Penthouse units where vacancy can erase 50% to 75% of annual income.
6. B³ SCORING SYSTEM (0–100)
Liquidity Score: 68 (High 1BR depth is offset by 500+ day DOM outliers in large units and a 95-day median speed).
Rent Capture Score: 65 (Strong Yearly PPSF efficiency is balanced by severe vacancy leakage in the 'G' and Penthouse lines).
Appreciation Score: 82 (Significant 13.5% neighborhood outperformance and durable compounding since 2003).
7. COMPOSITE SCORE & CLASSIFICATION
Composite Score: (68 × 0.35) + (65 × 0.30) + (82 × 0.35) = 72.0
Category Label: Hybrid (All scores ≥ 65).
Unit Mix Summary: ~58% 1BR, ~19% 2BR, ~4% 3BR+.
8. TRANSACTION EXAMPLES
Resale Appreciation:
Unit 2H (1BR): $473 PPSF (2003) → $998 PPSF (2022). +111% total. Drivers: (1) Market regime timing, (2) Line-level premium persistence.

Unit 4M (1BR): $833 PPSF (2006) → $920 PPSF (2013). +10.4% total. Drivers: (3) Liquidity shift.
Unit 12L (1BR): $1,332 PPSF (2021) → $1,392 PPSF (2023). +4.5% total. Drivers: (3) Liquidity shift.
Resale Depreciation:
Unit PHB (5BR): $1,886 PPSF (2016) → $1,569 PPSF (2019). -16.8% total. Drivers: (4) Unit size / unit mix imbalance.
Unit 8A (2BR): $1,275,000 (2011) → $750,000 (2020). -41.2% total. Drivers: (4) Unit size / unit mix imbalance.
Unit 18H (2BR): $1,696 (2020) → $1,347 (2025). -20.6% total. Drivers: (1) Market regime timing.

9. RISKS & RED FLAGS
Chronic Long Resale DOM: Avoid 4BR and combination units; they exhibit a median DOM of 512 days and discounts exceeding 35%.
Income Leakage: The 'G' rental line is a major risk, with DOM reaching 284 days, erasing most of the annual yield.
What NOT to buy: Oversized low-floor units (e.g., 8A). These units show the building's worst price persistence and high sensitivity to unit mix imbalance, resulting in significant resale depreciation.
10. EXECUTIVE SUMMARY
Liberty House is a Hybrid asset that serves as a core performance anchor for Battery Park City, outperforming the sub-neighborhood by 13.5%. The building’s health is driven by its 1BR segment, which maintains steady resale volume and captures elite rent efficiency up to $99/SF. While the building demonstrates robust long-term compounding since 2003, investors must navigate significant "income leakage" in the rental market for larger units and severe liquidity risk in the 4BR+ sector where marketing periods can exceed 500 days. Opportunity lies in high-floor 'C' and 'F' lines for capital growth, while risk is concentrated in oversized units prone to chronic market lag and pricing drawdowns.
Assumptions & Disclosures:
Sponsor Normalization: The building was built in 1985. The dataset provided begins in 2003. One transaction (8J in 2004) was reclassified as sponsor-driven due to DOM ≤ 30 days within the early data window. Post-normalization median DOM remained 95 days.
Benchmark: Analysis utilizes the NYXRCSA Oct 2025 index of 331.14 for temporal context.
