Story summary

In Park City, Utah, Cloudflare CEO Matthew Prince has been locked in a years-long legal battle with neighbors Eric Hermann and Susan Fredston-Hermann over the construction of an 11,000-square-foot mansion on King Road. The dispute escalated when Prince sued the couple over their Bernese Mountain dogs, claiming they unleashed waste on his property and harassed his family. A judge recently dismissed two lawsuits filed against Prince's extensive project, which neighbors contested due to its size, height, and design. This latest court ruling marks a significant setback for the Hermanns in their efforts to legally challenge the construction of Prince’s mansion. The conflict has garnered local attention with “Save Sasha and Mocha” stickers appearing around Park City, highlighting the neighborhood tensions arising from the project's controversial nature.

🔮 Residents of the East 61st Street co-op — some of whom are among the wealthiest people in America — last week escaped a highly contested $2 billion buyout that would have forced them from their homes over a proposed renovation to turn their building into a hotel and residence managed by the Dorchester Collection.
🔮 America’s already frozen housing market could be headed for an even deeper chill next year — with Goldman Sachs warning that stubbornly high mortgage rates will keep buyers sidelined and homeowners trapped in their properties.
🔮 “This is a buyer’s market born out of caution, not strength,” Redfin senior economist Asad Khan said in the report. “Buyers have tremendous negotiating power in most of the country because so many other would-be buyers have been priced out of the market, or scared off by economic uncertainty,” he added.
🔮 The attraction may also have financial implications for homeowners.
🔮 Toledo’s relative affordability may help explain its strong showing.
🔮 A multimillion-dollar home may come with sweeping views and lavish amenities — but a top public school rating isn’t necessarily part of the package.
🔮 America’s housing affordability crisis could drag on for at least another five years — and for New Yorkers, the wait could stretch well beyond a decade.
🔮 Chicago may have lost some of its biggest billionaires, but finding an apartment in the Windy City has never been more competitive.
🔮 Erica Terwillegar and her partner, Peter Molinari, are fighting to hold on to their $26,000-a-month condo at one of New York’s most exclusive addresses.
🔮 American homebuyers are increasingly turning to adjustable-rate mortgages as borrowing costs surge — a gamble that could leave some homeowners facing monthly payment increases of more than $1,000.
