The Harder Question Is Whether Buyers Will Commit
Southern California real estate is facing a difficult combination: renewed inflation pressure, expensive financing and buyers who have more reasons to postpone a major commitment. For commercial investors, the concern is whether a property's income will support its operating expenses, debt and required return. For high-end residential buyers, it is whether the purchase still makes sense alongside growing household costs, business uncertainty and the value of keeping cash available.
My concern is less about a single dramatic price decline than about the willingness—and ability—of buyers to complete transactions. A market can lose momentum while desirable properties retain substantial value. Sellers can hold their asking prices, buyers can hold their cash, and very little business can get done between them.
The conflict in the Middle East is a major part of the current pressure. Disrupted oil flows affect fuel and freight costs, which work their way into business operations and construction. Tariffs add another source of uncertainty for building materials. Higher borrowing costs then make those more expensive projects and purchases harder to finance.
These forces affect commercial property throughout Southern California and luxury residential property in communities such as Arcadia in different ways. Understanding those differences matters before deciding to buy, sell, refinance or build.
The Cost Shock Reaches Far Beyond the Fuel Pump
The Inflation Report Looks Backward;
Purchase Decisions Look Forward
The Bureau of Labor Statistics reported that consumer prices rose 3.4% over the year ending August 2026. Prices increased 0.4% during August, following a 0.1% increase in July. Gasoline accounted for more than one-third of August's monthly increase, while energy prices were 16.3% above a year earlier. BLS: August Consumer Price Index
That report describes prices already measured. It does not capture every cost increase that will appear in a future freight invoice, contractor's bid or lease negotiation.
There is an important qualification: annual headline inflation was also 3.4% in July, and annual inflation excluding food and energy eased to 2.4% in August. The evidence therefore supports renewed monthly pressure, especially from energy; it does not establish that every inflation measure is accelerating together. BLS: August Consumer Price Index
For real estate, the forward-looking question is whether a buyer can confidently estimate the next several years of ownership costs. Uncertainty about those costs can discourage a commitment before it becomes visible in completed sales.
California Diesel Has Already Crossed the $8 Threshold
The Energy Information Administration's September 14 weekly survey put average on-highway diesel at $6.285 per gallon nationally and $8.039 in California, including taxes. California's average was $3.068 higher than a year earlier. These are weekly averages, not prices at every station. EIA: Gasoline and Diesel Fuel Update
That distinction matters. A possible $8 national average would be a further adverse scenario; an $8 California average is already present in the reported data.
Diesel costs reach real estate through deliveries of concrete, steel, fixtures and equipment; trucking and rail logistics; construction machinery; and the businesses that occupy commercial buildings. Suppliers may absorb part of an increase, pass some through, or change prices when contracts renew. Goods do not automatically rise in price by the same percentage as diesel, but repeated increases can put pressure on several parts of a project budget at once.
For a tenant, that may mean less money available for an expansion. For a developer, it may mean a contractor's quote needs updating before financing is even complete. For a household, higher everyday spending can reduce the comfort level around a larger monthly payment.
Construction Faces Material Costs as Well as Energy Costs
NAHB's analysis of August producer-price data found residential building-material prices, excluding energy, 5.1% above a year earlier. Energy inputs to residential construction rose 6.6% in the month. These measures describe inputs, not the percentage increase in every finished building's total cost. NAHB: Energy Prices Rise Again in August
Tariffs are an additional concern. In its September 17 discussion of proposed building-material tariff relief, NAHB identified higher costs, supply-chain disruption and difficulty pricing new homes as continuing problems. Proposed relief is not the same as relief already in effect. NAHB: Building-Material Tariff Relief
The practical issue is the combination: materials, delivery, labor, financing and the time needed to finish and sell or lease a project. A development that appeared viable under an earlier budget may no longer offer enough margin for the risk involved.
Higher Borrowing Costs Make the Same Property Harder to Buy
On September 16, the Federal Reserve raised its federal-funds target range by a quarter percentage point to 3.75%–4.00%. Federal Reserve: September Policy Statement
The federal-funds rate is not the rate on a commercial mortgage or a luxury-home loan. Longer-term Treasury yields, inflation expectations, lender pricing and the borrower's risk also matter. A Fed increase does not translate into an identical increase in every mortgage. Nevertheless, tighter financing conditions make it harder for a marginal transaction to work.
Freddie Mac's national average for a 30-year fixed mortgage reached 6.95% on September 17, up from 6.76% a week earlier and 6.26% a year earlier. Its survey covers conventional conforming purchase loans; it is a useful benchmark, not an Arcadia jumbo-loan quote. Freddie Mac: Primary Mortgage Market Survey
My working expectation is that another Fed increase at the October meeting is a serious possibility, with additional tightening possible if inflation remains persistent. That is a market assessment, not an announced decision. The next scheduled meeting is October 27–28. Federal Reserve: Meeting Calendar
For buyers, the more useful discipline is to test the transaction at financing terms available now and under a less favorable scenario. A purchase that only works if rates fall quickly carries a risk that deserves explicit attention.
Commercial Real Estate: Pressure on Income, Debt and Transaction Volume
Commercial property is particularly exposed because acquisition decisions depend on several moving parts at the same time: tenant income, operating expenses, financing, future capital needs and resale assumptions. The current environment can weaken more than one of those assumptions together.
Rising Expenses Can Reduce Income Faster Than Owners Expect
Consider a hypothetical property collecting $1 million in annual operating revenue, with $600,000 in operating expenses. Its net operating income, before debt service, is $400,000.
If expenses rise 10% while revenue stays unchanged, expenses become $660,000 and net operating income falls to $340,000—a 15% decline. The property's revenue has not fallen, but the income available to support debt and investor returns has.
At an unchanged hypothetical 6% capitalization rate, dividing those income figures by the cap rate produces an indicated value of approximately $6.67 million before the expense increase and $5.67 million afterward. This is an illustration, not an appraisal or a forecast for a particular property. It shows why expense control and realistic income assumptions matter so much.
A lease may allow some expenses to be recovered from tenants. That shifts the immediate burden; it does not eliminate it. A tenant paying more for occupancy, inventory and transportation may have less capacity to renew at a higher rent or commit to additional space.
Refinancing Can Change the Decision Even When a Building Is Occupied
An owner with a favorable fixed-rate loan can be in a very different position from an owner approaching maturity. The latter may face a higher debt-service requirement, a more conservative valuation or a need to contribute additional equity.
Marcus & Millichap's September 18 public research summary specifically highlights the difficulty rising rates create for investors with maturing debt and the possibility that sustained borrowing costs will require commercial prices to adjust. It also recognizes longer-term opportunity. Both points can be true: a property may have a sound long-term purpose and still be difficult to finance at today's price. Marcus & Millichap: Fed Rate Hike—Challenge or Opportunity?
This is where the gap between seller expectations and buyer capacity widens. A seller remembers earlier pricing. A buyer's lender is evaluating today's income and debt service. Unless the price, financing structure or required equity changes, the deal can stall.
Southern California's Commercial Markets Are Under Uneven Pressure
The latest completed-quarter reports illustrate why broad claims about a single commercial market can mislead:
- Los Angeles office: CBRE's second-quarter report shows vacancy at approximately 26% and roughly 430,000 square feet of negative net absorption, meaning occupied space contracted. A building competing for tenants may need to budget for downtime, improvements and concessions in addition to ordinary expenses. CBRE: Los Angeles Office, Q2 2026
- Orange County industrial: Vacancy reached 5.5%, while average asking rent fell 3.9% from the previous quarter to $1.49 per square foot per month on a triple-net basis. Space under construction was down 65.7% from a year earlier. That is a difficult combination for a project relying on rising rents to offset higher development costs. CBRE: Orange County Industrial, Q2 2026
- Inland Empire industrial: The picture was more mixed. Vacancy improved to 7.4% and new leasing was strong, yet asking rents still eased and taking rents fell 2.8% from the first quarter. Occupier activity can improve while landlords remain under pressure on the rent actually achieved. CBRE: Inland Empire Industrial, Q2 2026
These reports cover the second quarter; they are not measurements of September's transaction response to the latest rate increase. They show the property conditions on which the current financing and cost shock is landing.
Multifamily and retail require their own analysis. Apartment underwriting must account for repair and turnover costs, collections, and the ability to achieve projected rents. Retail analysis must examine the strength of the actual tenant and the lease. A financially secure tenant under a durable lease presents a different risk from a business already struggling with thinner margins.
Development and Office Conversions Face a More Demanding Test
Higher construction costs can discourage new projects even when the completed space would serve a real need. Developers need enough expected income or sale proceeds to cover acquisition, construction, financing, carrying costs and a return for taking the risk.
Office-to-residential conversion illustrates the issue. My experience at Marcus & Millichap included work involving downtown Los Angeles office space being converted into high-end apartments and lofts. That background makes me particularly attentive to the difference between an attractive concept and a project whose numbers actually work.
A lower office acquisition price does not settle the question. The buyer still needs to evaluate the building's suitability, conversion scope, approvals, construction budget, financing and achievable residential revenue. Longer schedules create additional carrying costs. If costs increase while achievable rents remain uncertain, a promising conversion may need a lower purchase price, more equity or a different plan.
High-End Residential: Substantial Wealth Does Not Remove Hesitation
Luxury-home buyers are not all dependent on a large mortgage, and their financial positions differ widely. But the ability to purchase and the willingness to purchase are separate questions.
In Arcadia's high-end residential market, the relevant analysis is the property's competitive position within its own price range: recent comparable closings, competing inventory, condition, lot characteristics and the buyer's actual financing options. A regional statistic provides context; it cannot replace that work.

Fewer Sales Can Coexist with Firm Prices
The California Association of REALTORS® reported that Southern California existing single-family sales fell 4.8% year over year in August, while the regional median price rose 2.9%. Statewide sales, by contrast, were up 1.4%. C.A.R.: August Sales and Price Report
That combination is relevant to the current concern: fewer completed transactions do not automatically produce an immediate fall in median prices. Nor does a rising median establish that every property's value increased; the mix of homes sold matters.
C.A.R. also reported that the statewide share of million-dollar sales slipped from 35.5% in July to 35.2% in August, its third consecutive monthly decline. These are broad statewide figures, not an Arcadia luxury-market index. They support caution about assuming the upper end is insulated, without establishing a local luxury price decline. C.A.R.: August Sales and Price Report
A Large Loan Magnifies the Payment Difference
For illustration, a $2 million, 30-year fully amortizing loan has monthly principal and interest of approximately:
| Hypothetical fixed interest rate | Monthly principal and interest |
|---|---|
| 6.00% | $11,991 |
| 7.00% | $13,306 |
| Difference | $1,315 per month |
That is approximately $15,780 more per year, before property taxes, insurance, maintenance or association charges. These are calculated examples, not lender offers; a buyer's jumbo-loan terms will depend on the application and lender.
An affluent household may be able to absorb the difference and still decide it would rather wait. If business costs are increasing at the same time, maintaining liquidity may feel more valuable than purchasing a larger home immediately.
Cash Buyers Still Have an Ownership-Cost Decision
A cash purchase removes mortgage payments, but it does not remove property taxes, insurance, utilities, maintenance, landscape care or the cost of future improvements. It also commits capital that could otherwise remain available for business needs or other investments.
For that reason, I would not assume that a market with cash buyers is unaffected by inflation or higher rates. The effect may appear through greater selectivity, more attention to price and condition, or a longer decision process rather than a failed loan qualification.
This is an assessment of the incentives buyers face, not a claim that every luxury buyer is withdrawing. A distinctive, well-positioned home can still attract a decisive purchaser.
Renovation Uncertainty Can Change What Buyers Are Willing to Pay
A residence needing substantial work carries a second purchasing decision: the buyer must commit to the house and to an uncertain construction budget. Where contractor bids, materials or financing are expensive, that uncertainty can create a preference for a completed home—or a demand for a larger discount on one needing work.
National builder sentiment reinforces the broader caution. The NAHB/Wells Fargo Housing Market Index fell to 32 in September; 38% of surveyed builders reported cutting prices and 66% reported using sales incentives. This is a national new-home survey, not a measure of Arcadia resale homes, but it shows the strain at the point where construction costs meet buyer demand. NAHB: September Builder Sentiment
For a luxury seller, the response is to price against current competition, explain the home's condition clearly and address known issues early. For a buyer, it is to obtain realistic ownership and renovation figures before treating an apparent discount as a bargain.
The Same Pressures, Different Decisions
| Current pressure | Commercial property | High-end residential |
|---|---|---|
| Higher operating costs | Less net income if rents or reimbursements do not keep pace | A larger household carrying-cost commitment |
| Expensive debt | Lower supported loan proceeds, higher debt service or more equity needed | Higher payments on large mortgages and more incentive to preserve cash |
| Construction uncertainty | More demanding development, improvement and conversion budgets | Greater scrutiny of homes needing renovation |
| Buyer hesitation | Wider gaps between asking prices and underwritten values | More selective offers and potentially longer decisions |
These are economic channels, not a prediction that every property will experience the same result. They explain why an attractive asset can become harder to transact even when its long-term usefulness remains intact.
Why I Am Planning for Pressure into Early 2027
My planning assumption is that these conditions could persist through at least the first quarter of 2027. A quick return to cheap fuel, easy financing and confident buyers is not something I would build into a purchase or development budget.
The EIA's September outlook gives that caution a factual basis. It assumes some Middle East export constraints will last through year-end and that the region's oil production will remain below pre-conflict averages until the second quarter of 2027. It also projects unusually low U.S. distillate inventories through much of 2027. EIA: September Short-Term Energy Outlook
The same forecast anticipates improving oil flows and lower average crude prices in 2027. It is therefore evidence for a prolonged adjustment, not proof that prices must rise continuously. Its assumptions were finalized September 3 and could change as the conflict, shipping access and production evolve. EIA: September Short-Term Energy Outlook
A durable improvement in oil supply would help. It would not instantly reset existing contracts, rebuild inventories, lower every mortgage quote or remove the other costs facing property owners. Conversely, a longer disruption would make the current pressure more difficult to work through.
Put the Current Numbers Ahead of the Preferred Outcome
The next decision should start with the specific property and the buyer's or owner's capacity to carry it through an unfavorable period.
For commercial property, I would examine actual income and expenses, lease rollover, deferred work, the loan's maturity date and realistic refinancing terms. Then I would test what happens if income disappoints or costs remain elevated longer than expected.
For a high-end residence, I would examine comparable sales, competing listings, current financing, insurance and other ownership costs, and firm estimates for any planned work. The goal is to understand the entire commitment before negotiating the price.
Some transactions will still make sense. Others will require a price adjustment, a different structure or more time. What concerns me in this market is committing to yesterday's assumptions while paying today's costs.
If you are evaluating a commercial property anywhere in Southern California, or a high-end home in the Arcadia area, contact Brion Costa, CCIM, to review the transaction against current market conditions and your objectives.
