254 Park Avenue South
1. BUILDING OVERVIEW (ANALYST FRAMING)
Building Type: Condo Conversion (Vintage: 2008 Conversion / 1913 Construction)
Scale: 13 Floors, 123 Units
Classification: Yield-Oriented (Secondary: Defensive)
Sponsor Normalization Disclosure:
Transactions Reclassified: Approximately 35–40 transactions between 2009–2011 were identified as sponsor-driven (DOM < 30 days or "No Listing").
Impact: Early pricing baselines ($1,000–$1,200 PPSF) appear artificially consistent. Excluding these reveals that true resale liquidity is highly volatile, with frequent "No Listing" off-market trades distorting perceived velocity.
Analyst Framing: 254 Park Avenue South functions primarily as a high-velocity rental engine rather than an equity compounder. Post-sponsor appreciation is statistically negligible for the majority of the building, with numerous resale pairs showing flat or negative returns over 5–8 year holds. The asset captures tenants efficiently (studios/1-beds) but fails to capture capital growth against the NYXRCSA benchmark.
2. UNIT MIX & COMPOSITION
Analysis inferred from transaction history.
Unit Type | Lines (Inferred) | % of Activity | Role in Portfolio |
Studio | G, H, J, K, M | ~40% | Volume Driver. High turnover, rental-heavy. |
1-Bedroom | B, C, L, N, P | ~40% | Liquidity Core. The most traded product. |
2-Bedroom | A, D, KL (Combined) | ~20% | Volatility Trap. Slower absorption, highest capital risk. |
Impact: The building is dominated by transient inventory (studios/1-beds). This "dorm-style" mix supports rental yield density but suppresses the scarcity required for capital appreciation in the larger units.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
A. Liquidity (Ranked Fastest $\to$ Slowest)
Studios (G/M Lines): Median DOM ~30–45 days. High churn.
1-Bedrooms (C/N Lines): Median DOM ~50–70 days.
2-Bedrooms (A/D Lines): Median DOM 90+ days (e.g., Unit 3A: 132 days; Unit 4D: 251 days historically).
B. Appreciation (Compound Growth)
Benchmark Context: NYXRCSA Index rose from ~220 (2012) to ~330 (2025), a +50% market move.
254 PAS Performance:
Studios/1-Beds: 2–3% CAGR (tracking inflation, lagging market).
2-Bedrooms: 0% to <1% CAGR. Multiple instances of negative real returns.
4. RENT CAPTURE ANALYSIS
MANDATORY: Effective Annual Rent Calculation Note: High rental DOM in specific periods erodes nominal gains.
A. Rent Capture by Line
1-Bedroom (e.g., Unit 4C, 2023/2024)
Achieved Rent: ~$8,500 – $9,500
Rent/SF: ~$150 PSF (Nominal High)
Avg Rental DOM: ~50 days
Efficiency: Moderate Leakage.
Calculation: $8,500 $\times$ (315 $\div$ 365) = $7,335 Effective Monthly Rent.
2-Bedroom (e.g., Unit 7B, 2021 - Example of Risk)
Achieved Rent: $4,995 (COVID low, but illustrative of drag)
Avg Rental DOM: 268 days
Efficiency: Failure.
Calculation: $4,995 $\times$ (97 $\div$ 365) = $1,327 Effective Monthly Rent.
Insight: While extreme, this highlights the risk of holding out for price in this building.
Current Regime (2025):
Unit 6A (1 Bed): $5,000 rent. 54 DOM.
Efficiency improves in current market, but DOM remains the primary cost center.
5. B³ SCORING SYSTEM (0–100)
A. Liquidity Score: 62
Speed: Studios move fast; larger units drag the average down.
Consistency: High volume of transactions, but high dispersion in DOM (0 days to 200+ days).
Depth: Deep market for rentals, shallow for resale profit.
B. Rent Capture Score: 74
Rent Efficiency: High PPSF on rentals (often >$100/SF), but DOM friction (~40-50 days avg) prevents a higher score.
Stability: Strong demand due to location (Flatiron/Park Ave S), ensuring occupancy eventually.
C. Appreciation Score: 28
Magnitude: Failure. 0–1% CAGR for many units during a bull market.
Durability: Proven inability to protect capital against inflation over medium-term holds (5-8 years).
6. COMPOSITE SCORE & CLASSIFICATION
Composite Score: (62 $\times$ 0.35) + (74 $\times$ 0.30) + (28 $\times$ 0.35) 21.7 + 22.2 + 9.8 = 53.7
Category: Yield-Oriented (Leaning Distressed on Equity) Note: The building scores decently on rent and liquidity but fails chemically on appreciation. It is a "Cash Flow only" asset.
7. TRANSACTION EXAMPLES
Drivers: 1) Market regime timing, 3) Liquidity shift, 4) Unit mix imbalance.
Resale Appreciation (Modest / Long Hold Required)
Unit 7D (2 Bed):
Buy: $1.80M (Jun 10, Sponsor-linked) $\to$ Sell: $2.90M (Aug 22).
Hold: 12 years. Total: +61%. CAGR: ~4.0%.
Driver: Market regime timing (Entry at market bottom).
Unit 4K (Studio/1 Bed):
Buy: $1.10M (Aug 15) $\to$ Sell: $1.35M (Jun 22).
Hold: 7 years. Total: +22%. CAGR: ~2.9%.
Driver: Line-level premium persistence.
Resale Stagnation / Depreciation (The Norm)
Unit 4N (1 Bed):
Buy: $970K (Feb 15) $\to$ Sell: $960K (Sep 23).
Hold: 8.5 years. Total: -1.0% Loss.
Driver: Market regime timing (Bought peak, sold recovery).
Unit 6A (1 Bed):
Buy: $1.475M (Apr 16) $\to$ Sell: $1.475M (Jun 18).
Hold: 2 years. Total: 0% Flat.
Driver: Liquidity shift (Inability to capture short-term gains).
Unit 3A (2 Bed):
Buy: $1.68M (Dec 12) $\to$ Sell: $1.775M (Feb 21).
Hold: 9 years. Total: +5.6%. CAGR: 0.6%.
Context: Market rose ~40% in this period. Unit underperformed massively.
Driver: Unit size/mix imbalance (Larger units do not compound here).
Unit 9A (2 Bed):
Buy: $1.71M (Jun 12, est from history) $\to$ Sell: $1.80M (May 25 - Pending/Recent).
Hold: ~13 years. Total: +5%. CAGR: <0.5%.
Driver: Line-level premium persistence (Lack thereof).
8. RISKS & RED FLAGS
The "Peak 2015" Overhang: Units purchased between 2014–2016 are consistently reselling at flat or negative numbers today.
Vacancy Drag: Rental DOMs frequently spike to 40–70 days. Owners budgeting for 0% vacancy will miss yield targets.
No "Step-Up" Value: The 2-bedroom units (A/D lines) do not command the premium over 1-bedrooms that is typical in this neighborhood; they are valued merely as "two 1-bedrooms combined" rather than luxury homes.
9. EXECUTIVE SUMMARY
254 Park Avenue South is a Yield-Oriented asset that excels at generating rental velocity but fails to generate capital appreciation. Post-sponsor data confirms that while the building commands strong nominal rents ($100+ PSF) on its dominant studio/1-bedroom inventory, resale values have effectively flatlined for a decade. Buyers from 2015 are frequently exiting at a loss or break-even in 2023–2025. The asset is best utilized as a defensive rental hold; expectations of equity growth should be set to zero.
B³ SCORECARD
Metric | Score | Notes |
Liquidity | 62 | High velocity in small units; congestion in large units. |
Rent Capture | 74 | Strong face rents diluted by frequent turnover vacancy. |
Appreciation | 28 | Critical Weakness. Flat/Negative returns common. |
Composite | 53.7 | Yield-Oriented |
Unit Mix Summary:
Core Inventory: Studio & 1-Bedroom heavy (~80% of activity).
Opportunity: Rental cash flow on Lines C, N, P.
Avoid: Capital appreciation plays on Lines A, D (2-Beds).
