450 Washington Street
1. BUILDING OVERVIEW (ANALYST FRAMING)
Building Type: Luxury Condo Conversion (2009 Build / 2022 Conversion).
Scale: 176 Units, 15 Floors.
Classification: Yield-Oriented
Justification: 450 Washington Street defines the "Yield-Oriented" classification. While it is a recent conversion with short resale history, the Rent Capture pillar is performing at an elite level, frequently delivering gross yields of 6.0%–7.3%—figures that are statistical outliers for Manhattan condos,. The building exhibits extreme "Unit Mix Imbalance" (Driver 4), creating a bifurcated liquidity profile: studios and 1-bedrooms clear rapidly, while large-format 3-4 bedroom units suffer from chronic days on market (DOM) drag, often sitting for 300+ days,. Despite the NYXRCSA benchmark reaching 330.28, resale appreciation is volatile, with some flippers realizing gains (Driver 1: Market Regime) while others face losses due to high carrying costs and competition from remaining sponsor inventory.
2. UNIT MIX & COMPOSITION
Inventory based on transaction data–.
Studio/1BR: Dominant Volume. (~78 sales recorded). The high velocity engine of the building.
2BR: Moderate share (~31 sales).
3BR: Significant inventory (~25 sales). Sticky liquidity.
4BR+: Luxury tier (~14 sales). highly illiquid.
Analysis: The building is numerically weighted toward smaller units, which supports its high rental velocity. However, the 3BR+ units (lines like 02, 06, 09) represent the bulk of the "stale" inventory. This mix creates a liquidity trap: the building appears liquid on average due to small unit volume, but the family-sized assets are difficult to exit,.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
Note: As a 2022 conversion, most inventory is Sponsor. Analysis focuses on the emerging resale/flip market.
A. Liquidity (Normalized Resale Data) Liquidity is strictly correlated with ticket price and size (Driver 4).
Fastest Lines (Small/Flip): Unit 1201 (30 days), Unit 705 (84 days).
Slowest Lines (Large/Sponsor-like): Unit 520 (392 days), Unit 1006 (346 days), Unit 909 (325 days).
B. Price Strength
Studio/1BR: Trades at ~$2,200–$2,700 PPSF,.
3BR/4BR: Trades at ~$2,200–$2,600 PPSF but requires deep discounting (-5% to -11% from ask) to move,.
C. Appreciation
Early Flips: Buyers who entered in late 2023/early 2024 and sold in late 2025 are seeing gains of 15–25% (Driver 1: Market Regime Timing).
Volatility: Smaller units held for shorter periods show mixed results, including losses (Driver 3: Liquidity Shift).
4. BUILDING-WIDE PPSF TREND (NORMALIZED)
2023 (Launch/Early): ~$2,000–$2,300 PPSF,.
2025 (Current): ~$2,300–$2,600 PPSF,.
Conclusion: Compounding. The building has successfully drafted off the rising NYXRCSA index (up to 330.28), lifting the floor price from ~$2,000 to ~$2,300 over 24 months.
5. RENT CAPTURE ANALYSIS
This is the building’s primary performance driver. The yields are exceptionally high.
A. Rent Capture Metrics
Unit 1002 (3BR): Rented Jun 2024 for $40,000/mo ($231/SF).
Yield Context: Sold Apr 2025 for $6.5M. Note: Sale occurred after rent, likely investor exit.
Implied Gross Yield: ~7.3% (Elite).
Unit 802 (3BR): Rented Jan 2025 for $35,000/mo ($202/SF).
Unit 512 (2BR): Rented May 2024 for $11,500/mo ($130/SF).
Yield Context: Sold Mar 2024 for $2.095M.
Gross Yield: 6.5%.
B. Rent Appreciation
Unit 802 Trend:
Aug 2023: $35,000.
Jan 2025: $35,000.
Result: Flat at the top of the market. $202/SF is likely the ceiling.
6. B³ SCORING SYSTEM (0–100)
Liquidity Score: 55
Speed: Bifurcated. Small units are 80/100; Large units are 20/100 (300+ DOM).
Depth: Active market, but heavily reliant on sponsor absorption.
Rent Capture Score: 95
Efficiency: Elite. Rents consistently $130–$200 PSF,.
Yield: Gross yields of 6–7% are rare for Tribeca and provide a massive valuation floor.
Appreciation Score: 65
Magnitude: Strong short-term gains (15–25%) for early flippers.
Durability: Short track record. Some losses in studios suggest volatility.
7. COMPOSITE SCORE & CLASSIFICATION
Composite Score: (55 × 0.35) + (95 × 0.30) + (65 × 0.35) = 70.5
Category:Yield-Oriented (Secondary: Hybrid) Note: While the composite score is high, the liquidity drag on large units and the exceptional 7% yields firmly place this in the Yield category.

9. RISKS & RED FLAGS
The "Big Unit" Trap: 3BR and 4BR units have median DOMs of 154 and 106-147 days, with some reaching 300+,. Do not expect liquidity in the large format units.
Rental Ceiling: Rents of $200–$230 PSF are extraordinary but likely capped. If the rental market softens, the yield-based valuation supporting the $2.5M+ prices will crumble.
Short-Term Volatility: The -9.5% loss on Unit 401 proves that short-term flips are not guaranteed, even in a rising market (NYXRCSA up).
10. EXECUTIVE SUMMARY
450 Washington Street is a high-octane Yield-Oriented asset that behaves more like an income fund than a traditional condo. Post-sponsor analysis reveals a building where elite rental metrics—consistently delivering 6.5%–7.3% gross yields,—provide a sturdy floor for valuations. While small units (studios/1BRs) are highly liquid and have generated 15–25% gains for early flippers (Driver 1: Market Regime), the building suffers from significant liquidity drag in its large-format inventory, where units often sit for 6–12 months. Investors should approach this as a cash-flow play, targeting 1BRs for liquidity or 3BRs only if they can tolerate year-long disposition timelines to capture the massive $35k/mo rental income.
B³ SCORECARD
Metric | Score | Notes |
Liquidity | 55 | Bifurcated. 1BRs fast; 3BRs/4BRs very slow (300+ DOM). |
Rent Capture | 95 | Elite. 6.5%–7.3% Yields. Rents up to $230/SF. |
Appreciation | 65 | Strong early flips (+15-25%), but short track record. |
Composite | 70.5 | Yield-Oriented |
Disclosures:
Sponsor Normalization: Sales with "No Listing" or <30 DOM in 2023–2024 were treated as Sponsor inventory.
Data Context: Most sales are initial sponsor dispositions; "Resale" analysis focuses on the confirmed flips identified in 2024-2025.
Benchmark: NYXRCSA Index (Nov 2025: 330.28) indicates a strong bull market, which 450 Washington's small units have tracked well.
