New York City is dodging America's foreclosure troubles. But for how long? Filings fell 23% even as they rose nationwide. Early warning signs suggest the city's luck may not last, @mcdiduch reports.

November magazine out today!
What does it take to turn big ambitions into reality? “Anyone can talk. Ideas, opinions, political bluster. This month’s magazine has action: conflict, work and momentum,” @Eisenpress writes in her latest editor’s letter.
TRD’s November issue examines the people making moves in real estate — from Michael Meldman’s global luxury empire and Pam Liebman’s next chapter at Compass to the fortunes, family feuds and obstacles shaping the industry.
Ahead of tomorrow's midterm election, here's a closer look at where real estate's top donors are spending their money across the country: therealdeal.com/data/nationa…

It’s been a bumpy year for commercial mortgage-backed securities — but a good one for special servicers, who now hold the highest volume and share of CMBS loans since the financial crisis.
@mcdiduch has the latest on CMBS trends for #TRDData.

Real estate is consistently one of the top donors to federal elections. What does the industry's spending look like this midterm? I went thru 100s of 1000s of FEC docs to find out, so you don't have to. Read the analysis here: therealdeal.com/data/nationa…

We actually covered this phenomenon last year: therealdeal.com/new-york/202…
A study of condo resales in Manhattan over the last few years found that:
- 1 in 3 units sold for a loss
- over HALF of those who bought from 2016 to 2020 sold for a loss
The worst housing market over the last decade is somewhere people would least expect.
Manhattan.
Values in New York County dropped by -11.9% from September 2016 to 2026, falling from 1.41M to 1.24M.
Which is an astounding -51.2% drop in inflation-adjusted terms.
Condo/co-op/townhome values inn Manhattan are now at record lows compared to incomes and rents.
Making it one of the most undervalued housing markets in America, despite it's still expensive price tag.
Values have actually started turning recently, up 3% YoY.
Meaning it could be a good time to buy in NYC.
