地产大亨杰夫·格林认为，尽管美国经济表面稳固，但正走向危险的轨道。他警告称，不断膨胀的国债和不可持续的财政赤字支出是主要隐患。格林指出，高企的利率正抑制房地产市场的“巨大繁荣”，许多潜在买家和卖家都在等待利率下降。一旦利率下调，将有更多业主愿意出售房屋，从而增加市场供应，这对于难以负担购房的首次购房者来说是利好。然而，格林也担忧，如果政府继续依赖印钞和刺激措施，经济可能最终陷入“下行螺旋”，他以生动的比喻形容了这种长期累积风险的必然爆发。

💰 格林预测，一旦利率下降，美国房地产市场将迎来“巨大繁荣”。他解释说，当前近7%的抵押贷款利率远高于四年前的3%以下，这使得许多拥有低利率长期贷款的房主不愿出售房屋，因为他们不想放弃低成本融资。利率的下降将鼓励这些房主重新融资并搬家，从而增加市场上的房屋供应，尤其有利于首次购房者。

📉 格林对美国经济的长期前景表示担忧，他认为经济增长长期以来依赖于“印刷的货币”和政府刺激措施，这种模式是不可持续的。他强调，尽管近期可能通过财政支出暂时维持经济增长，但不断增长的国债和利息成本正在将美国推向一个危险的境地，他将其比作高速行驶却忽视潜在危险，最终将面临不可避免的事故。

⏳ 格林将美国经济的现状描述为一种“下行螺旋”，这不仅源于财政问题，也与人口结构变化有关。他提到，随着人口老龄化和领取社会保障金的人数增加，将移民“赶出国家”是不明智的。这种人口挑战与日益增长的债务相结合，加剧了经济的脆弱性，预示着未来可能面临更严峻的挑战。

Real estate billionaire Jeff Greene expects a "huge boom" for house prices if interest rates fall.The real estate billionaire told BI the US economy looks solid but is on a dangerous track.Greene rang the alarm on the ballooning national debt and said deficit spending is unsustainable.

Interest rates are holding back a "huge boom" in the housing market, billionaire real estate developer Jeff Greene told Business Insider.

In a wide-ranging interview, the Florida-based property tycoon said that prospective home buyers and sellers were "waiting for rates to come down." The annual interest on a 10-year, fixed-rate mortgage is still close to 7%, a sharp increase from below 3% four years ago.

Federal Reserve Chair Jerome Powell said earlier this month that tariff-related uncertainty was the main reason the central bank hadn't cut rates since December. Mortgage rates closely track the Fed's benchmark rate.

"If rates come down, we'll have a huge boom in housing prices," Greene told BI.

A reduction in rates would likely result in more houses on the market, as homeowners who took out long-term mortgages at low rates would then be willing to refinance and move home, Greene said.

"People have locked in loans for any number of years into the future, and so they're not going to give up those houses" before rates fall, he said.

Increased supply could help first-time buyers get on the housing ladder, Greene said. It's "always been difficult" for young people to buy a home as they're competing against older people with deeper pockets, he said, but it's "particularly hard now" when rates are high and there are fewer homes for sale.

A 'downward spiral'

Greene said that federal spending, quantitative easing, low interest rates, and other forms of government stimulus have underpinned US economic growth for decades.

"The economy's been running on printed money for a long time; it's not a secret," he said. "We've just printed money and given it to people."

President Donald Trump's recently passed "Big Beautiful Bill" is likely to "keep the party going" and stave off an economic slowdown, Greene said.

Greene said Trump struck him as someone who would negotiate deals so his tariffs wouldn't cause "huge dislocations in the economy."

So far, the market seems to agree, and that outlook likely explains why stocks are at record highs, Greene said.

But he warned about the rising national debt, and the US government's growing interest costs.

"We've just kicked the can down the road for however many more years," he said. "You can drive 130 miles an hour down the road and have no accident, but at some point, somebody's going to pull out in front of you and you're going to die," he added.

Greene also said that "throwing our immigrants out of the country" was unwise when America has an ageing population, with an increasing proportion of people living on Social Security.

"We're kind of in a downward spiral," Greene said of the demographic challenges and mounting debt.
