The war started in late February. By mid-March, your maintenance quotes were wrong, your tenant retention assumptions were outdated, and the mortgage rate environment your spring strategy was built on had completely reversed. Here is what is actually happening and what to do about it.
What Is Happening Right Now
Going into 2026, property managers finally had reason to feel good about the year ahead. The U.S. housing market was showing its best fundamentals in three years. Inventory was climbing. Mortgage rates had broken below 6% for the first time since 2022. Economists were calling it a genuine recovery. Then February 28 happened.
The U.S. and Israel launched coordinated airstrikes against Iran. Within hours, oil markets went into shock. The Strait of Hormuz, which carries about 20% of global oil and LNG supply, effectively closed. Brent crude surged past $110 per barrel. Inflation fears spiked. Treasury yields climbed. And the 30-year fixed mortgage rate, which had been sitting at a tantalizingly low 5.99%, climbed to 6.38% over four consecutive weeks — the largest sustained jump since the April 2025 tariff shock.
For property managers and HOA boards, the ripple effects did not stop at mortgage rates. Energy costs, materials prices, insurance premiums, contractor rates, and tenant financial stress all moved in the same direction at once. This is what property management during a war economy actually looks like in practice.
Mortgage Rates and the Housing Slowdown
The most immediate and visible impact of the Iran conflict is what it did to the mortgage rate trajectory that property managers had been counting on. And the reason this matters so directly to your business is simple: every buyer who gets priced out of a home purchase does not disappear. They stay in your rental units, often longer than they planned.

One day before the February 28 strikes, rates were at 5.99%, the lowest since September 2022. They have climbed every single week since. The Mortgage Bankers Association reports mortgage applications for home purchases dropped 5% in the first week of the conflict. The spring selling season that was supposed to revive the for-sale market is now stalling.
Zillow chief economist Mischa Fisher summed it up plainly in a late March 2026 update: the housing market had entered 2026 with data-driven optimism, but elevated mortgage rates were now acting as "a slight drag on the spring season, already removing about a third of the year-over-year affordability gains" seen when rates fell below 6%. Zillow had originally forecast a 4.3% gain in existing home sales this year. That forecast is now hostage to how quickly the conflict de-escalates.
What the rate shift means for affordability
• The climb from 5.99% to 6.38% (Freddie Mac, March 26) adds roughly $50 to $63 per month on a median-priced home purchase, depending on loan size
• Over a 30-year loan, that translates to more than $22,000 in additional total interest
• First-time buyers are hit hardest, since they have no prior sale equity to cushion the higher borrowing cost
• The Federal Reserve held rates at 3.50% to 3.75% in March and signaled just one potential cut in 2026, now expected in October at the earliest
Here is the practical takeaway: the higher mortgage rates climb above what your tenants could afford as buyers, the stickier your tenant base gets. That is good for occupancy. It also means fewer of your tenants will leave voluntarily, which changes how you should think about lease renewal negotiations this spring.
Oil Prices, Inflation, and Rising Property Costs
Mortgage rates are the headline. But for the property manager actually running a portfolio day to day, the more operationally disruptive part of this crisis is what it is doing to the cost of maintaining and operating a property.
Oil is not just gasoline. It is an input in the production of PVC piping, roofing membranes, sealants, asphalt, insulation, and the transportation of every contractor who drives to your building. When the Strait of Hormuz closes, the shock travels through global supply chains in ways most property managers do not see coming until the invoice arrives.
Construction materials, already elevated from post-pandemic disruptions and the 2026 tariff regime, are now posting their sharpest year-over-year increases since early 2022. Here is what the Associated General Contractors of America reported in March 2026:

When the pain actually shows up: the 30 to 60-day delay
Here is something most property managers miss. Construction suppliers typically adjust pricing 30 to 60 days after energy costs move. That means quotes you received in late March are still based on pre-war input costs. The actual pricing pressure hits in May and June. If you are planning capital projects or major repairs for Q2, get your quotes locked in now.
• HVAC system replacements will cost more as aluminum and copper components reprice
• Plumbing repairs are exposed to the copper and brass spike, up 15.1% year over year
• Roofing projects using asphalt-based membranes face petroleum-driven cost increases
• Landscaping, pest control, and waste removal will reprice at contract renewal as diesel costs pass through
Insurance and utilities: the secondary cost wave
Beyond direct maintenance, property managers are absorbing secondary cost increases that trace back to the same energy shock. Insurance carriers price replacement cost into their premiums, and as materials prices rise, so do replacement valuations. That means your next insurance renewal will likely come in higher than the last one. Utility costs, particularly heating oil and natural gas, are also affected by the Persian Gulf disruption.
Action item for HOA boards
If your last reserve fund study predates Q4 2025, its cost assumptions are nowmaterially obsolete. Commission an updated study before approving any 2026 capital projects. Add a 15 to 20 percent contingency buffer to all project quotes received before March 2026. For a primer on reserve fund mechanics, see ManageCasa's HOA reserve fund guide (linked in the sources below).
What This Means for Property Managers
The honest read on the Iran war impact on U.S. property management is that it is squeezing from both sides at once. Demand conditions are moving in your favor. Operating costs are moving against you. The managers who understand both sides of that equation will navigate 2026 significantly better than those who only see one.
Rising rents vs. tenant affordability
Higher mortgage rates push buyers out of the market and into yours. That gives landlords real pricing leverage at lease renewal in 2026. At the same time, the same inflation that is lifting your costs is also squeezing your tenants through higher gas, groceries, and utilities. This tension is real and it plays out at the renewal table.
• Landlords in markets without rent control have genuine pricing leverage at renewal this spring
• That said, the cost of a vacancy in this environment is high: marketing, lost rent, and turnover typically exceed the benefit of a $50 to $100 per month increase if the tenant walks
• Tenants under financial stress from inflation pay later and push back harder on increases; expect more collection friction regardless of how the conversation goes
• Transparent communication about rising operating costs is not just good practice, it is tactically smart: it frames rent adjustments as cost recovery, not opportunism. See ManageCasa's guide to communicating HOA fee increases for a framework that translates directly to rental contexts
Longer tenant stays
One of the clearest near-term trends is an extension of average tenant tenure. When the path to homeownership closes, renters stay put. That is operationally good for property managers who value stability. It also means a concentrated wave of renewal negotiations in Q2, all happening in the same inflationary window. You will be having the same cost conversation with a lot of different tenants in a short period.
• Expect above-average lease renewal rates through Q3 2026
• Plan for a Q2 concentration of renewal discussions as spring leases come due
• Some tenants who had planned to buy this year will request longer lease terms for certainty; consider whether offering 18 or 24-month leases at a modest discount gives you occupancy certainty worth the tradeoff
Budget pressure across the board
HOA boards and professional property managers are facing the same uncomfortable arithmetic: the budgets approved in 2025 were built on 2025 cost assumptions. Those assumptions are now wrong. The Iran war changed the cost environment in a matter of weeks, not quarters.
• Capital improvement projects are likely to come in 15 to 25 percent over original quotes
• Vendor contract renewals in Q2 and Q3 will reflect higher fuel and materials costs
• Insurance premium renewals will incorporate higher replacement valuations
• Reserve fund adequacy, already a concern for more than 70 percent of HOAs according to Association Reserves' analysis of 100,000+ reserve studies, now requires fresh review. See ManageCasa's HOA financial management guide for a reserve fund assessment framework
Opportunities for Landlords and HOAs in a War Economy
Economic disruption has a way of separating operators who are prepared from those who are not. The landlords and HOA boards that come through 2026 in the best shape will not be the ones who simply absorbed each new cost as it arrived. They will be the ones who used this period to tighten their operations, improve their financial visibility, and build the kind of systems that hold up when the environment is unforgiving.
This is exactly the kind of market where the right property management platform pays for itself. When every dollar in your operating budget is under scrutiny, manual processes and disconnected workflows become expensive liabilities, not just inconveniences. Every delay in rent collection, every maintenance invoice reconciled in a spreadsheet, every communication that slips through the cracks represents a real cost to your net operating income.
Automate rent collection: your first line of defense against cash flow uncertainty
When tenants are financially stressed, payment timing gets less predictable. Late payments that might have been outliers in a stable economy become more common when gas, groceries, and utilities are all rising at once. Automated rent collection through ManageCasa removes the friction from the process on both sides: tenants get flexible payment options that make on-time payment easier, and property managers get real-time cash flow visibility without manual tracking. In a market where cash flow predictability is increasingly hard to count on, automated collection is not a convenience. It is a financial control.
Reduce operational costs with centralized management
One of the most effective responses to rising input costs is finding and eliminating the operational waste that already exists in your workflows. Every hour spent reconciling maintenance invoices manually, re-entering tenant information across disconnected systems, or generating owner reports from scratch is an hour that compounds into real money as your portfolio grows. ManageCasa's platform centralizes communications, maintenance tracking, financial reporting, and lease management in one place, so the work that scales poorly in manual systems stops consuming your time.
Improve communication with residents and boards
In a volatile economic environment, residents want to understand what is driving cost changes. Property managers and HOA boards that communicate proactively, explaining why a project is running over budget or why an assessment increase is necessary, retain the trust that reactive managers lose. ManageCasa's built-in communication tools make consistent, documented resident communication a repeatable workflow, not something you scramble to do when a problem surfaces. That trust has real dollar value when you need board approval for a budget amendment or tenant cooperation during a maintenance project.
Stay ahead of budget shifts with real-time reporting
The Iran war has made financial planning harder because cost assumptions are changing faster than annual budgets can accommodate. Property managers using ManageCasa can run income and expense reports in real time that surface cost overruns as they happen, not at year-end when it is too late to adjust. For HOA boards managing reserve funds and capital budgets, that visibility is the difference between a proactive conversation and an emergency special assessment. See ManageCasa's HOA budgeting guide for a full framework on adjusting budgets mid-year when assumptions change.
The bottom line
Demand conditions favor you: fewer buyers means more long-term renters. Cost conditions demand efficiency: rising expenses require tighter operational control. Technology advantage is real: operators on modern platforms absorb disruption better. ManageCasa is built for exactly this environment.
The 2026 Outlook: Short-Term and Long-Term Scenarios
The honest answer to where the U.S. housing market goes from here is that nobody knows. And that is not a hedge, it is the actual situation. The economic impact of the Iran conflict depends almost entirely on variables, primarily the conflict's duration and whether it expands to include sustained infrastructure damage in the Persian Gulf, that no economist can reliably forecast right now.
What Marcus and Millichap, one of the most closely watched commercial real estate research firms, published in March 2026 is the most useful planning framework available. They outlined three scenarios:
Source: Marcus & Millichap Iran War Multifamily Report, March 2026
Where markets are pricing things right now
As of late March 2026, financial markets are effectively treating Scenario 2 as the base case. The Federal Reserve held its benchmark rate at 3.50% to 3.75% at its March meeting, raised its core inflation forecast to 2.7%, and the CME FedWatch tool currently shows a 74% probability that rates remain unchanged through December 2026. Oxford Economics projects that without a relatively quick resolution, higher mortgage rates and softening labor conditions will suppress residential spending throughout the year.
Fannie Mae still projects rates drifting toward 5.75% to 6.0% by late 2026, but that projection requires meaningful de-escalation in the near term. If conflict persists into summer, that forecast becomes hard to defend. Zillow's scenario modeling gives the clearest picture of what each outcome means for housing activity:
• Conflict ends by April 2026: existing home sales still rise 3.48% year over year
• Conflict ends by July 1: the gain drops to 2.33%
• Conflict ends by September 1: the gain falls to 1.21%
• Rates stay elevated and unemployment also rises: a 0.73% decline is projected
For property managers, the planning implication is to build your operating budgets and lease renewal strategy around Scenario 2 for at least the next 90 days. Keep enough flexibility to adapt if things resolve faster than expected. Texas and California markets, both of which ManageCasa tracks separately, are likely to see the most pronounced rental demand effects given their structural affordability challenges and large renter populations.
"Trying to time the perfect mortgage rate is a losing game because the variables that move rates, like geopolitics, Federal Reserve policy, inflation, and global capital flows, are genuinely unpredictable."

Frequently Asked Questions
How is the Iran war impact on the U.S. housing market affecting property managers specifically?
The most direct effects are a cost squeeze and a demand shift happening simultaneously. On the cost side, construction materials are up 15% to 39% year over year, insurance replacement valuations are rising, and vendor contracts are repricing as fuel costs pass through. On the demand side, the jump in mortgage rates from 5.99% to 6.38% has priced many would-be buyers out of the market, pushing them back into rentals and extending average tenant tenure. For property managers, that means more stable occupancy but tighter operating budgets. The managers who will navigate this best are those who update their capital budgets now, lock in vendor pricing before the delayed cost pass-through hits in May and June, and treat automated operations as a financial control rather than a convenience.
How does the Iran war affect rent prices in the USA?
The war does not directly set rent prices, but it is reshaping the conditions that determine them. Higher mortgage rates are reducing homebuyer competition, which gives landlords more pricing leverage at lease renewal. At the same time, the same inflation driving up oil, materials, and insurance costs is also squeezing tenant budgets through higher gas, food, and utility bills. The practical result: landlords in markets without rent control have real justification for measured rent increases at renewal — operating costs are rising — but aggressive increases carry risk because financially stressed tenants are more likely to leave or pay late. The cost of filling a vacancy in the current environment often exceeds the annual benefit of a $50 to $100 per month rent bump. Tenant retention is unusually valuable in 2026.
Should landlords raise rent during inflation in 2026?
Modest, cost-recovery-justified increases at lease renewal are defensible and, for many landlords, necessary. Insurance premiums, maintenance costs, and vendor contracts are all moving higher. That said, the decision should account for local rent control laws, the tenant's payment history, and the true cost of vacancy in your market. A well-documented explanation of why costs have increased — framed as operating reality, not opportunism — significantly reduces pushback and improves tenant cooperation. Transparent communication before renewal conversations begin is the most underrated tool landlords have in an inflationary environment. See ManageCasa's guide on communicating HOA fee increases for a framework that applies directly to rental lease renewals.
What do oil prices and the Iran conflict mean for property maintenance costs?
Oil is a direct input in the production of roofing membranes, PVC piping, sealants, asphalt, and insulation — and it drives the transportation cost of every contractor who visits your property. With Brent crude surging more than 30% since the conflict began, these materials are repricing. The critical thing to understand is the timing lag: suppliers typically adjust pricing 30 to 60 days after energy costs move. Quotes you received in late March 2026 are still based on pre-war input costs. The real maintenance cost pressure arrives in May and June. Capital improvement projects budgeted in 2025 should be stress-tested now, and a 15% to 20% contingency buffer added to all active quotes. For HOA boards, this means any reserve fund study completed before Q4 2025 is already using obsolete cost assumptions.
Is the U.S. heading into a recession because of the Iran war?
Most analysts are not forecasting a full recession in the base case — but they are stress-testing one. Marcus and Millichap's March 2026 analysis outlines three scenarios. In their moderate scenario (three to six months of conflict without major infrastructure damage), U.S. GDP stays near 2.25% for 2026 with no Federal Reserve rate cuts. In their most severe scenario (prolonged conflict with significant Middle East energy infrastructure damage), GDP falls below 2% and recession risk increases materially. As of late March 2026, financial markets are pricing in the moderate scenario. The Federal Reserve held its benchmark rate at 3.50% to 3.75% at its March meeting, raised its core inflation forecast to 2.7%, and the CME FedWatch tool shows a 74% probability that rates remain unchanged through December 2026. Property managers should plan for the moderate scenario while maintaining enough operational flexibility to adapt if conditions worsen or improve faster than expected.
How should HOA boards adjust their reserve fund plans given rising construction costs?
The most important immediate step is to commission or update a reserve fund study if your last one predates Q4 2025. The cost assumptions in older studies — for roofing, HVAC, structural metal, and plumbing — are now materially understated due to the tariff-driven and war-driven materials price spikes of early 2026. Association Reserves, which has analyzed more than 100,000 reserve studies, reports that 74% of HOAs are already underfunded. In the current cost environment, that gap is widening. Before approving any 2026 capital projects, add a 15% to 20% contingency buffer to all active quotes. For boards facing assessment increases, transparent financial communication with residents — explaining the operating cost environment clearly and early — significantly reduces the friction of necessary fee adjustments. ManageCasa's HOA reserve fund guide and budgeting guide both offer practical frameworks for navigating this.
What is the 2026 outlook for the U.S. housing market if the Iran conflict continues?
It depends almost entirely on duration. Zillow's chief economist Mischa Fisher modeled four outcomes. If the conflict resolves by April, existing home sales still rise 3.48% this year. If it persists to July 1, the gain shrinks to 2.33%. Through September 1, only 1.21% growth. If elevated rates and rising unemployment persist all year, sales could decline 0.73%. Fannie Mae and the Mortgage Bankers Association both project rates drifting toward 5.75% to 6.0% by late 2026, but those forecasts assume meaningful de-escalation. For property managers, the planning implication is clear: build budgets and lease renewal strategies around the moderate case — sustained elevated rates, rising maintenance costs, and strong rental demand — for at least the next 90 days. Monitor Freddie Mac's weekly PMMS and the CME FedWatch tool as the two clearest leading indicators of how this scenario is evolving.
