NYC real estate under $20 million: a buy, or a trap?

The numbers behind the episode, the borough prices, and each host's pretend $20M call.

The little story
A 29-unit Manhattan walk-up sold for $285,110.

312 East 106th Street, East Harlem. Rent-stabilized. That's about $9,800 per apartment, less than two months of Manhattan's median asking rent (about $5,000). Then it sold twice more in 11 months.

Unit count is 28–30 depending on the source.

Sources: ACRIS, the city's deed records (block 1677, lot 44); The Real Deal, Feb 25, 2025; Manhattan rent from StreetEasy, September 2026

Bar height = sale price. Bought in a 2016 portfolio on a plan to raise rents; the 2019 rent law ended that plan and the loan went bad.

The trap, in one building

$5M building at a 6% cap rate earns, after expenses$300,000 Loan payments: $3.25M (65%) at 6.5%, 30 years−$246,500 Left for you on $1.75M of your cash$53,500 (3.1%) Same $1.75M in 10-year Treasuries at 4.86%$85,050

Cap rate = yearly rent left after expenses ÷ price. NYC apartment buildings averaged about 6.1% (Matthews, Q2 2026). When the loan rate is above the cap rate, borrowing shrinks your return.

Thomas
BUY the fear
  • Stabilized walk-ups, Bronx and northern Manhattan
  • About $100K per apartment, half borrowed: ~400 apartments
  • Why: prices already down ~45% (GREA, Apr 2026); the freeze is in the price
A
Augustine
BUY quality
  • 5–6 free-market buildings, Brooklyn and Queens, each under 25,000 sq ft
  • 30% borrowed: ~55 apartments
  • Why: 1.4% vacancy (HPD, 2023 survey), rents rising (StreetEasy, Sept 2026), low debt dodges the rate trap
P
Paul
TRAP for debt, buy with cash
  • $14M in 10-year Treasuries at ~4.86% (FRED, Nov 6, 2026; ~$680K a year)
  • $6M all cash: one free-market mixed-use building in Queens
  • Why: borrowed money barely beats a Treasury; buys more if prices fall

Paul's verdict

Both, and the line is debt. Borrowed buys are a trap at today's rates. With cash and patience, small free-market buildings are a buy. Stabilized buildings only at distressed prices, with cash, and someone who can fix a boiler at 2 a.m. Ada scores every portfolio each episode.
