US mortgage rates rose to 7.03%, the highest level since January of last year, driven by soaring US Treasury yields. This surge places significant pressure on housing-linked stocks, including Opendoor Technologies (NASDAQ: OPEN), Rocket Companies (NYSE: RKT), and Lennar Corporation (NYSE: LEN).

Treasury yields increased due to rising US public debt and Federal Reserve signals regarding continued interest rate hikes. The higher borrowing costs directly impact demand for homes and mortgage originations.

Opendoor faces turnaround headwinds

Opendoor’s business model, which involves buying and reselling homes, relies heavily on customer mortgage access. Rising rates have coincided with a management-led turnaround effort following a prolonged slowdown.

Recent results indicate slowing business activity:

• Revenue fell to $883 million in the June quarter from $1.57 billion in the same period last year.
• Homes sold dropped to 2,339 from 4,299.
• Adjusted EBITDA swung to a $4 million loss from a positive $23 million.

The stock has declined 56% this year and 70% over the last 12 months.

Rocket Companies sees lower originations

Rocket Companies stock has experienced a strong sell-off, bottoming at $11.47, its lowest level since May 2025. The share price is down 50% from its yearly high, reducing market capitalization from $65 billion to $34 billion.

Rising rates are leading to lower origination volumes. Adjusted revenue for the second quarter was $2.76 billion, a slight decrease from $2.8 billion in the first quarter. Management forecasts third-quarter revenue between $2.5 billion and $2.7 billion.

Lennar contends with cost and demand pressures

Lennar Corporation shares ended the week at $82.15, down 33% from their yearly high and 50% from all-time highs. The company faces dual challenges: reduced housing demand due to high mortgage rates and rising operational costs, with the Producer Price Index (PPI) remaining above 3%.

Financial performance reflects these pressures:

• August quarter revenue decreased to $8.04 billion from $8.8 billion year-over-year.
• Nine-month revenue fell to $22.6 billion from $24.8 billion.
• Net earnings dropped to $283 million from $590 million in the prior year's August quarter.

What the numbers show

A divergence exists between Lennar’s top-line contraction and its bottom-line erosion. While quarterly revenue declined approximately 8.6% ($8.8 billion to $8.04 billion), net earnings fell 52% ($590 million to $283 million). This disproportionate drop in profitability compared to revenue suggests that fixed costs or margin compression are intensifying faster than sales volume declines, likely exacerbated by the PPI-driven cost inflation mentioned in the source.

Opendoor Technologies (NASDAQ: OPEN) reported robust second-quarter 2026 results, achieving its highest weekly contract volume in years with over 700 contracts signed in a single week. The company is on track to exceed $9 billion in annual revenue, driven by improved seller conversions at stable spread levels and significant operational efficiencies.

Management expressed confidence in reaching adjusted net income (ANI) profitability by the end of 2026, citing a structural improvement in unit economics rather than temporary market tailwinds.

Operational Efficiency Gains

The company highlighted substantial reductions in operating expenses relative to acquisition gross merchandise value (GMV). Marketing costs, previously a significant drag, fell to 0.3% of acquisition GMV, down from 1.6% under the previous "Opendoor 1.0" model. Variable operations costs also declined, now standing at 50 basis points of acquisition contract GMV, with management projecting this to remain around 70 basis points of acquisition GMV after accounting for contract fall-throughs.

Fixed operations costs dropped sharply to 2.1% of acquisition GMV in Q2, compared to over 8% in the third quarter of the prior year. This reduction is attributed to a shift from consultants to engineers and data scientists, leveraging code scalability over manual labor.

What the Numbers Show

The divergence between contract volume growth and marketing spend reveals a fundamental shift in customer acquisition efficiency. While the company signed more than 500 contracts per week—up 5x year-over-year—marketing spend for the quarter was just $5 million, compared to over $80 million during a similar volume period in the past. This indicates that growth is being driven by improved conversion rates at stable spread levels rather than aggressive pricing or increased advertising spend, validating management's claim that the profitability path is based on sustainable unit economics.

Margin Outlook and Seasonality

Contribution margins have improved every quarter this year, reaching target levels in Q2. However, management noted that Q3 margins are expected to decline seasonally, a historical trend where margins typically degrade by nearly 500 basis points between Q2 and Q3. Despite this seasonal dip, Opendoor expects to break with historical norms by delivering higher contribution margins in Q4 than in Q3.

Net interest costs currently run slightly above 2% of revenue, scaling with inventory turnover which stands at approximately three times per year. Management indicated ongoing efforts to lower these financing costs further.

Strategic Initiatives

Opendoor is integrating mortgage services directly into its transaction process to reduce friction. In Colorado, its first launch market, more than half of scheduled closes are financed through Opendoor Home Loans. In Texas, six weeks post-launch, nearly one in five transactions utilized the company's mortgage product. Management described this as building financial infrastructure inside the transaction rather than bolting it on, aiming to expand margins and reduce risk.
