Ps90 - 220 West 148 Street
1. BUILDING OVERVIEW (ANALYST FRAMING)
Building Type: Postwar Resale Condo (Built 1903, Converted 2010).
Scale: 6 Floors, 75 Units.
Primary Category: Yield-Oriented.
Secondary Category: Cyclical.
Justification: Post-sponsor data indicates a building that experienced massive initial cyclical appreciation from 2011 to 2016 but has since entirely mean-reverted, punishing recent buyers. Early sponsor sales cleared at highly discounted baseline pricing ($450–$600/SF) in 2011–2012, allowing early buyers to capture immense equity as the building matured to a mid-cycle peak of $800–$930/SF between 2016 and 2019. However, the mature resale market (2022–2024) demonstrates massive friction and price deterioration, with 2BR and 3BR valuations correcting downward to $719–$850/SF. This late-stage mean-reversion completely decouples the asset from the NYXRCSA benchmark, which pushed to historic highs of 330–333 in late 2025 and early 2026. With capital preservation failing over the last 5 years and severe resale illiquidity on larger units, the building functions best as a Yield-Oriented asset via rental capture on smaller footprints.
2. UNIT MIX & COMPOSITION
Based on transaction-weighted data across 91 explicitly sized recorded sales:
Studio: ~17% of sales volume (16 transactions).
1BR: ~26% of sales volume (24 transactions).
2BR: ~53% of sales volume (48 transactions).
3BR+: ~3% of sales volume (3 transactions).
Influence on Liquidity & Rent Behavior: The building is heavily anchored by 2BR units. While Studios and 1BRs form a reliable backbone for rental yield—frequently clearing the rental market in under 30 days—the building's dominant 2BR inventory suffers catastrophic illiquidity on the secondary sales market. This unit size imbalance creates a structural drag, causing even premium 2BR lines to sit for 200 to 350+ days when attempting to offload.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
A. Liquidity
Fastest Resale Velocity: Resale liquidity is incredibly fragmented. The rare efficient clears (e.g., 5J in 58 days, 1C in 87 days) heavily depend on steep vendor discounting.
Slowest Resale Velocity: The building's core 2BR units sit for chronic, destructive durations on the resale market. Unit 5H sat for 353 days, 2C for 348 days, and 2P for 216 days.
B. Price Strength
Mid-cycle premium stacks (high floors and large 2BRs) have broken down. Units that successfully commanded $900+/SF between 2016 and 2019 have corrected to a volatile baseline of roughly $710–$850/SF today.
C. Appreciation
Lines are heavily cyclical. Holders from the 2011–2013 sponsor baseline realized massive structural compounding, but buyers who entered during the 2016–2019 mid-cycle peak exhibit negative compounding and widespread equity destruction.
4. BUILDING-WIDE PPSF TREND (NORMALIZED)
2010–2013 (Sponsor Clearance): High volume clearing at heavily discounted baselines of $450–$600/SF.
2015–2019 (Mid-Cycle Peak): Rapid expansion and premium realization, peaking at $800–$936/SF.
2021–2024 (Drawdown / Normalization): A drastic reset and liquidity crisis, settling back down to $685–$850/SF. Conclusion: Cyclical / Mean-Reverting. Value is currently adjusting downward from the 2019 mid-cycle peak, completely failing to track the macro growth proven by the NYXRCSA index from 2020 to 2026.
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 2M (Studio). Achieved $2,950/mo. DOM 10. Effective Rent = $2,950 × (365 - 10) ÷ 365 = $2,869/mo.
Example 2 (Moderate Efficiency): Unit 5F (2BR). Achieved $4,200/mo. DOM 21. Effective Rent = $4,200 × (365 - 21) ÷ 365 = $3,958/mo.
Example 3 (Severe Leakage): Unit 5C (2BR). Achieved $4,250/mo. DOM 132. Effective Rent = $4,250 × (365 - 132) ÷ 365 = $2,713/mo.
B. Rent Appreciation Rent per SF performs efficiently on smaller layouts, generally yielding $38 to $49/SF. Despite the capital destruction seen on the mature resale market, the building captures yield highly efficiently on its Studio and 1BR units, processing tenants in 10 to 30 days, heavily offsetting sales depreciation.
6. B³ SCORING SYSTEM (0–100)
Liquidity Score: 32
Speed: Failing. Normalized resale DOM routinely exceeds 150 to 350 days for 2BR layouts.
Consistency: Low. Extreme friction on the secondary market.
Rent Capture Score: 74
Efficiency: Strong ($38–$49/SF).
Absorption: Excellent on Studios (10-15 DOM), volatile on 2BRs.
Appreciation Score: 45
Durability: Cyclical. Widespread equity loss for peak buyers (2016-2019), but excellent historical compounding for initial 2011 sponsors.
7. COMPOSITE SCORE & CLASSIFICATION
Composite Score = (32 × 0.35) + (74 × 0.30) + (45 × 0.35) = 49.15 Category Assignment: Yield-Oriented. The asset fails defensive metrics due to extreme resale DOM drag on 2BRs, functioning most predictably as a rental income vehicle.

9. RISKS & RED FLAGS
Catastrophic Resale Illiquidity on 2BRs: The building's core inventory (2BR units) routinely sits for 150 to 350+ days (e.g., 2C at 348 days, 5H at 353 days), signifying deep secondary market friction.
Late-Stage Mean Reversion: Buyers who purchased during the 2016–2019 peak have seen their equity structurally destroyed, wholly missing the recent macro upswings of the broader NYC index.
Avoid: Do not buy 2BR or 3BR units anticipating capital appreciation or a quick exit. The holding cost of a 300+ day DOM entirely neutralizes theoretical value.
10. EXECUTIVE SUMMARY
PS90 (220 West 148 Street) is a deeply cyclical, Yield-Oriented post-war conversion that currently traps late-stage buyers in severe resale illiquidity. While the asset compounded wealth immensely for its initial 2011–2013 buyers, those entering at the 2016–2019 mid-cycle peak have suffered structural equity destruction, with recent 2BR valuations retreating to $719–$850/SF while battling catastrophic 200–350+ day market durations. Compounding this, the asset's trajectory has fully decoupled from the all-time highs tracked by the NYXRCSA benchmark. Despite capital preservation failures on larger units, the building's smaller footprints (Studios and 1BRs) operate as highly efficient rental vehicles, capturing excellent yield with DOMs frequently under 30 days. Investors should avoid this building for defensive value storage, utilizing it exclusively to farm yield on smaller units.
