Macro Trends
One in Five U.S. Mortgages Now Carry Rates Above 6%; A Ticking Time Bomb for Housing link

According to Apollo Chief Economist Torsten Sløk, 20% of all outstanding U.S. mortgages now have interest rates above 6%, marking a steep climb in high-cost debt since the Fed began hiking rates.
The data from the FHFA and Macrobond shows a rising share of homeowners locked into expensive loans, limiting mobility and keeping inventory artificially low.
This shift creates a two-tier housing market, older, low-rate mortgages vs. new, high-rate loans, which could distort pricing, refinancing, and demand patterns well into 2026.
My take: A lot of people are just stuck, those with low rates can’t afford to move, and new buyers can’t afford to get in. Until rates come down, the market’s going to stay pretty quiet.
Real Estate Trends
Rental Concessions Rise to New Level link
37.3% of Zillow listings included a giveaway in September (record high), up from 36.7% in August and far above 2019’s 14.4%. Concessions are likely to keep climbing into winter; once normalized, managers may have to cut face rents, pressuring NOI.
The split is regional: rent drops are concentrated in the South/Sunbelt/Mountain West (Austin, Denver, San Antonio, Phoenix, Orlando), while tighter, higher-barrier markets (Chicago, San Francisco, New York, Providence, Cleveland) are holding firmer. 37 metros saw concessions rise (led by Pittsburgh, Seattle, Richmond, Raleigh, Hartford) while 12 fell (including Birmingham, Los Angeles, Minneapolis, Cleveland, San Francisco).
Affordability is the best in four years as new supply floods the market: asking multifamily rent is $1,809 (−0.2% MoM) and annual growth slowed to 1.7% (second-lowest since 2021). Single-family rentals are up just 3.2% YoY , the smallest gain since 2016 , hinting at broader cooling.
My take: When this many landlords are giving away free rent, it usually means demand is softening faster than they’d like to admit. If this keeps up through winter, actual rents will start falling , especially in those oversupplied Sunbelt cities.
Industrial vacancies level off as leasing surges and construction slows link
Industrial leasing jumped 9.8% year-over-year to 682M sq. ft., driven by occupiers upgrading to newer facilities and outsourcing to 3PLs.
Despite 13 straight quarters of completions outpacing absorption, the vacancy rate stabilized at 6.6%, ending a two-year trend of steady increases.
Build-to-suit projects fueled 53.3M sq. ft. of net absorption in Q3, helping offset space returns from consolidating occupiers.
My take: Leasing strength from logistics players is keeping the industrial market from tipping. But if construction keeps rising faster than absorption, 2026 could finally test how deep demand really runs.
Homebuyers are saying no to chains and snapping up houses in cities with unique downtowns link
In Ridgewood and Chatham, NJ, buyers are paying more per square foot to live near authentic, walkable downtowns , even trading larger lots for proximity to cafes and shops. Homes in Chatham Borough sell for more than nearby Township homes thanks to access to local culture and transit.
The “post-pandemic reset” has fueled demand for small-town Main Streets filled with independent coffee shops, bakeries, and boutiques, as residents seek connection and community over convenience.
Real estate brokers note that too many chains or big-box stores near a town center now hurt buyer perception, as shoppers prefer local variety that reflects neighborhood character and engagement.
My take: The next premium isn’t just location, it’s local. Investors who bet on towns preserving authentic downtowns may see faster appreciation than in sprawling suburbs with copy-paste retail.
Home Equity Rates Decline in Third Quarter link
Equity-rich homes dropped to 46.1% of U.S. mortgaged properties in Q3 2025, down from 48.3% a year earlier despite record-high median home prices of $370,000.
Underwater homes climbed to 2.8% nationwide, rising year-over-year in 46 states, with the sharpest jumps in D.C. (+1.8 pts), Maryland (+1.1), and Louisiana (+1.1).
Florida, Arizona, and Colorado saw the biggest declines in equity-rich share (down 6–7 pts), while Vermont and the Midwest counties dominated the top of the equity leaderboard, with some reaching 90%+ equity-rich rates.
My take: The equity dip shows cracks forming beneath record prices, not a crash, but a cooling. Watch out for high-growth Sun Belt markets like Florida and Arizona; they’re shifting from “equity-rich” to “risk zone” faster than the headlines suggest.
Location Specific
San Diego life science leasing rebounds link
Q3 gross leasing hit 703,042 SF, powered by Novartis’ 466,598 SF build-to-suit at Campus Point; net absorption turned positive for the first time in ~12 months. Still, availability in the core cluster climbed to a record 31.2%.
Demand is clustering in built-out, turnkey spec suites with 24–36 month terms,seven such deals closed this quarter. Touring for <15,000 SF jumped in late September as tenants prioritize speed and flexibility over cost.
Vacancy nearly doubled YoY to 29.2% while under-construction fell to 1.0M SF from 4.3M SF (-77.7%); rents are steady but tenants are downsizing, sharing labs, or shifting to cheaper submarkets. Venture funding ticked up to $563M and post-IPO proceeds hit a record $5.2B, yet NIH tightening keeps capital scarce.
