300 East 79 Street
1. BUILDING OVERVIEW (ANALYST FRAMING)
300 East 79 Street is a Postwar Resale Condo (built 2008) located in the Upper East Side market. Standing 18 floors tall with 40 units, it is a boutique full-service asset.
Based on transaction history and the current NYXRCSA benchmark of 331.14 (Oct 2025), the building is classified as Yield-Oriented (Secondary: Lagging/Defensive).
This classification is justified by a distinct decoupling from the broader market. While the NYXRCSA index reached record highs in late 2025, 300 East 79 Street exhibits structural nominal depreciation compared to its 2014–2016 peak. Resale transactions in 2024–2025 clear at prices 10–20% below levels established a decade prior. For example, Unit 14A sold in 2024 for $400,000 less than it did in 2014. The building explicitly underperforms the Upper East Side sub-market by 21.6%. Value is derived from utility and rent capture rather than equity compounding.
2. UNIT MIX & COMPOSITION
Based on transaction-weighted data from 52 recorded sales, the inventory is heavily skewed toward 2-bedroom and 3-bedroom family units, differing from high-density 1-bedroom buildings:
1BR: ~6% of activity (Rare; e.g., Line 3A, 3C).
2BR: ~55% of activity (Dominant; e.g., Lines A, B, C; typically 1,160–1,367 sqft).
3BR: ~25% of activity (e.g., Lines 14A, 14B, PH lines; 1,663–2,157 sqft).
4BR+: ~14% of activity (e.g., Line 11B, 12B; ~2,664 sqft).
Influence on Behavior: The concentration of 2BR/3BR units creates a "primary residence" liquidity profile. Liquidity is significantly lower than commodity buildings, with median resale DOMs frequently exceeding 150 days as sellers of larger units struggle to match 2016 pricing expectations.
3. LINE (STACK) PERFORMANCE — RESALE ONLY
Note: Pursuant to the Sponsor Normalization Rule, transactions from 2008–2009 with "No Listing" are treated as Sponsor/Conversion clearing and excluded from resale liquidity metrics.
Liquidity:
Fastest: Rare anomalies during peak cycles. Unit 14A sold in 20 days in 2014. Unit 8B sold in 38 days in 2016.
Slowest: Current market friction is severe. Unit 7A took 277 days to sell in 2021. Unit 14A took 272 days in 2024. Unit 9B took 196 days in 2024. Unit 14B took 806 days in 2012.
Median Resale DOM: Recent 2024–2025 activity shows a median of ~196 days, indicating profound illiquidity compared to the liquid market standard (<90 days).
Price Strength:
Ceiling: The pricing power has collapsed. In 2016, Unit 8B sold for $1,883 PPSF. In 2025, Unit 5B sold for $1,411 PPSF.
Baseline: The current 2024–2025 baseline has reset to $1,400–$1,600 PPSF.
Discounting: Recent sales show persistent discounts. Unit 9B traded at $1,452 PPSF in 2024, down from $1,817 PPSF for the same unit in 2016.
Appreciation:
Negative Trend: Long-term holders are realizing nominal losses or flat returns. Multiple units sold in 2024–2025 for prices below their 2014–2016 basis (see Transaction Examples).
4. BUILDING-WIDE PPSF TREND (NORMALIZED)
The building is in a Structural Drawdown.
Cycle Peak (2014–2016): Sales frequently cleared $1,700–$1,880 PPSF.
Unit 8B (2016): $1,883 PPSF.
Unit 14A (2014): $1,864 PPSF.
Unit 9B (2016): $1,817 PPSF.
Current (2024–2025): Prices have reset to $1,400–$1,625 PPSF.
Unit 5B (Jan 2025): $1,411 PPSF.
Unit 9B (Jun 2024): $1,452 PPSF.
Unit 14A (Sep 2024): $1,623 PPSF.
Trend: Bearish/Decoupled. Despite the NYXRCSA index rising to 331.14 (all-time high), 300 East 79 Street is trading at valuations 15–20% lower than its peak a decade ago.

Catastrophic Failure
Insights: Rent capture is highly bifurcated. 2BR units can capture income efficiently (e.g., 12A in 3 days). However, larger units suffer from extreme friction. Unit 11B in 2019 sat for 324 days, destroying 89% of its annualized revenue potential. Even in 2022, 11B took 73 days to rent.
6. B³ SCORING SYSTEM (0–100)
Liquidity Score: 30/100 (Recent resale DOMs are consistently high: 119, 272, 196 days. Market depth is thin).
Rent Capture Score: 50/100 (Strong nominal rents for 2BRs, but severe penalty for catastrophic leakage in 4BR segments).
Appreciation Score: 20/100 (Structural depreciation; key units selling in 2024–2025 for less than 2014–2016 prices).
Composite Score: 31.0/100.

8. RISKS & RED FLAGS
Capital Erosion: Buying in the 2014–2016 window has guaranteed nominal losses upon exit in 2024–2025 (e.g., Units 14A, 9B). The building is not tracking the NYXRCSA benchmark.
Illiquidity: Recent sales of key units (14A, 9B, 7A) took 196–277 days to clear. This is a slow-moving asset.
Sponsor Price Trap: Units sold in 2008 (e.g., 5B) are trading at the exact same price in 2025, representing a "lost decade+ of wealth".
9. EXECUTIVE SUMMARY
300 East 79 Street is a Yield-Oriented boutique condo that acts as a capital trap for equity investors. Despite the NYXRCSA index hitting record highs (331.14), this building's pricing power has structurally regressed, with 2024–2025 resales clearing 13–20% below their 2014–2016 peaks. It explicitly underperforms the Upper East Side market by 21.6%. While 2BR units offer moderate rental utility ($7,950/mo), the building suffers from significant liquidity drag (median DOM ~196 days) and fails to compound value for long-term holders. Investors should view this strictly as a consumption purchase, assuming zero appreciation.
