Brewster Carriage House (372 Broome Street)
1. BUILDING OVERVIEW (ANALYST FRAMING)
Classification: Appreciation-Driven (Core)
372 Broome Street is a boutique prewar condominium (built 1856) in NoLita comprising only 9 units across 6 floors. Unlike high-velocity new developments, this building functions as a "Core" asset characterized by large floorplates (approx. 2,000–2,600 sq ft) and low turnover. Post-sponsor behavior reveals a bifurcation in performance: the "A" line and Penthouses exhibit strong long-term compounding, while the "B" line has shown susceptibility to stagnation.
The building is notably illiquid due to its unit size and price point. Resale listing days on market (DOM) frequently exceed 180 days, indicating that while value is preserved, exiting these positions requires significant patience.
Sponsor Normalization Disclosure: A cluster of 8 transactions occurred between June 2012 and July 2013 with "No Listing" status or clustered closing dates (e.g., Units 2B, 3A, 4A, 5A, PHA, 4B). These represent the Sponsor sellout baseline ($1,200–$1,700 PPSF). I have excluded these from resale liquidity metrics to reflect true market conditions.
2. UNIT MIX & COMPOSITION
Composition (Transaction-Weighted): The building has no "starter" inventory. It is composed exclusively of large-format lofts.
1-Bedroom: ~15% (e.g., Unit 3B, though nearly 2,000 sq ft).
2-Bedroom: ~40% (Lines B and N, ~1,970 sq ft).
3-Bedroom+: ~45% (Line A and Penthouses, ~2,100–2,600 sq ft).
Analysis: This heavy weighting toward large units (>1,900 sq ft) creates "Liquidity Shift" risks. There are no small units to facilitate rapid turnover or price discovery. The sheer size of the "1-Bedroom" units (1,982 sq ft) limits the buyer pool to those prioritizing space over bedroom count, slowing absorption.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
A. Liquidity (Ranked Fastest → Slowest): Open market liquidity is poor; however, "No Listing" trades suggest an active off-market network.
A Line (Large Lofts): Moderate off-market velocity. Recent trades (3A in 2022, 4A in 2023) occurred with "No Listing," implying insider/direct demand.
PH Line: Variable. PHS sold in 71 days (2022), but PHA took 179 days (2018).
B/N Line (Smaller Lofts): Slow. Unit 3N sat for 333 days (2021); Unit 4B sat for 220 days (2019).
B. Price Strength & Dispersion:
Premium Lines: Penthouses trade at a massive premium ($3,300–$3,500 PPSF), nearly double the building median.
Standard Lines: The A and B lines trade in the $1,700–$2,400 PPSF range.
C. Appreciation:
Long-Term Winners: Early buyers (2012) who held to 2018–2023 saw gains of 30–70%.
Short-Term Volatility: Recent high-end trades (PHB) have shown "Market regime timing" losses (-$200k between 2020 and 2022).
4. BUILDING-WIDE PPSF TREND (NORMALIZED)
2012 (Sponsor): ~$1,300–$1,700 PPSF.
2016–2018 (Peak 1): Appreciation to ~$2,000 (Lofts) and ~$3,400 (PHs).
2019–2021 (Correction): Softness visible. Unit 4B traded at $1,700 PPSF (2019) and Unit 3N at $1,513 PPSF (2021).
2022–2023 (Recovery): A-Line recovered to ~$2,400 PPSF.
Conclusion: Compounding (Long Term) but Cyclical (Short Term). The building beats the NYXRCSA benchmark over a 10-year horizon but is vulnerable to 10-20% drawdowns during softer regimes.
5. RENT CAPTURE ANALYSIS
MANDATORY METRIC: Effective Annual Rent
Unit 2A (Feb 2024): $13,750/mo × (365 − 67)/365 = $11,226/mo effective.
Rent/SF: ~$75/SF (Ask) -> ~$61/SF effective due to vacancy.
Unit 4B (Jun 2022): $14,227/mo × (365 − 12)/365 = $13,759/mo effective.
Rent/SF: ~$83/SF.
A. Rent Capture Efficiency: Moderate. While gross rents are high ($13k+), the PPSF yield is roughly $60–$85/SF. Compared to sale prices of $1,700–$2,400 PPSF, the yield is approximately 3.5–4.0%, which is standard but not "Yield-Oriented."
B. Rent Appreciation:
Unit 4B: $12,500 (2023) vs $14,227 (2022). A decline of -12% year-over-year, likely due to "Market regime timing" or unit-specific issues.
Unit 3B: $12,500 (2017). Comparing to Unit 2A ($13,750 in 2024), rent growth has been sluggish (<1.5% CAGR) over 7 years.
6. B³ SCORING SYSTEM (0–100)
Liquidity Score: 45
Open market trades are slow (DOM 220, 333, 179). Reliance on off-market "No Listing" deals hurts the transparency and liquidity score for standard sellers.
Rent Capture Score: 65
Rents are high in nominal terms but flat in growth. Vacancy spikes (67 days for Unit 2A) drag down the effective yield.
Appreciation Score: 80
Strong long-term compounding for 2012 buyers (Sponsor to Resale). Despite recent choppiness, the 10-year hold value creation is significant.
7. COMPOSITE SCORE & CLASSIFICATION
Composite Score: 63.25 Calculation: $(45 \times 0.35) + (65 \times 0.30) + (80 \times 0.35) = 15.75 + 19.5 + 28 = 63.25$
Category: Appreciation-Driven (Core) (Though the composite is <65, the Appreciation Score of 80 drives the thesis. It is a store of wealth, not a trading vehicle).
8. TRANSACTION EXAMPLES
Resale Appreciation Examples:
Unit 4A (Large Loft):
Buy: Jun 2012 ($3,767,525)
Sell: Sep 2023 ($5,200,000)

Sell: Mar 2019 ($3,350,000)
Result: +26.5% in 7 years (~3.4% CAGR).
Driver: Sponsor price normalization (Initial undervaluation).
Unit PHA (3 Bed / 3 Bath):
Buy: Jun 2012 ($7,127,750)
Sell: May 2018 ($9,020,000)
Result: +26.5% in 6 years (~4.0% CAGR).
Driver: Line-level premium persistence (PH premium).

Buy: Aug 2012 ($2,494,712)
Sell: Oct 2016 ($3,900,000)
Result: +56% in 4 years.
Driver: Market regime timing (Sold into the 2015-2016 peak).
Resale Depreciation / Flat Examples:
Unit PHB (Penthouse):
Buy: Mar 2020 ($7,700,000)
Sell: May 2022 ($7,500,000)
Result: -2.6% Loss in 2 years (Boom market).
Driver: Liquidity shift (Difficulty clearing ultra-high price points even in good markets).
Unit 3N vs 3B (Proxy Comparison):
Unit 3B Sold Jul 2013 ($2,900,000)
Unit 3N Sold Oct 2021 ($3,000,000)
Result: Effectively Flat (+3%) over 8 years.
Driver: Line-level premium persistence. The "B/N" line lags significantly behind the "A" line and Penthouses.
9. RISKS & RED FLAGS
Resale Liquidity Trap: Units like 3N (333 DOM) and 4B (220 DOM) demonstrate that if you miss the off-market window, you may be stuck on the market for 6–12 months.
B-Line Underperformance: The B/N line trades significantly lower ($1,500–$1,700 PPSF) compared to the A-Line and PHs. Do not price a B-line unit using A-line comps.
High Carrying Costs on Vacancy: With rents stagnating or dropping (Unit 4B rent drop 2022-2023), carrying a vacant unit here is costly.
10. EXECUTIVE SUMMARY
372 Broome Street is a "Core" wealth preservation asset that rewards long-term holders but punishes short-term traders. Post-sponsor data shows reliable compounding for 10-year holds (CAGRs 3–4%), particularly in the A-Line and Penthouses. However, liquidity is a major friction point; standard resale listings often languish for 6+ months (Liquidity Score 45). The building exhibits stark "Line-level premium persistence," where the B-line severely underperforms the rest of the building. This is an asset for patience, not yield or quick flips.
