Why property buyers are seeking higher grounds

Parts of Nairobi were submerged following heavy rains on March 07, 2026. [Nicholas Biwott, Standard] As unrelenting rains pounded the country and flash floods disrupted key areas around Nairobi, Kiambu, Narok and other regions, killing more than 40 people, the calamity has left tens of thousands displaced and properties worth millions of shillings destroyed. This exposed deep vulnerabilities in the country's urban infrastructure. The catastrophe - which turned city streets into rivers and stranded motorists disrupted flights and inundated settlements - is rapidly transforming how Kenyans think about land and property in a climateuncertain future. But beyond the tragic loss of life and livelihoods lies another impact that is gathering momentum: a structural shift in the real estate market as homebuyers, investors and lenders alike rethink where to build, buy and finance homes. "In conversations with clients over the past six months, flood risk has gone from being a commuter inconvenience to a dealbreaker," says Kihonge Kagiri, the founder and chief executive of Epic Prime Real Estate (Epic Prime Investments) He added that properties in lowlying or poorly drained areas have lost appeal. Buyers now ask one question before any other: Is this home safe when it rains? This shift isn't anecdotal. Real estate professionals across the country report that estates historically prized for their proximity to transport hubs or commercial centres are now evaluated based on elevation, drainage infrastructure and resilience planning. Areas without engineered stormwater systems are seeing slower sales and buyer hesitancy - and in some cases, price corrections. Kagiri notes that even banks and lenders are adjusting. "Mortgage approvals are becoming stricter if a property is in a known floodprone area, with due diligence increasingly incorporating climate risk assessments," he said. For investors, this dynamic is ushering in a cautious rebalancing: funds once earmarked for raw land or speculative buildings are being redirected to floodresilient developments, financial instruments like Real Estate Investment Trusts (REITs) or instruments less tied to physical location risk. In Nairobi's informal settlements - polylined homes near rivers in Mukuru, Mathare and Kibra - floodwaters once again ravaged lives. These neighbourhoods, already underserved by infrastructure, bore the brunt of the March floods, as waters overwhelmed drains and spilt over riparian zones. In Mathare, where many residents lost possessions and homes constructed of lightweight materials were washed away, displacement is more than a statistic - it's a vivid reminder that climate risk translates directly into human insecurity. The crisis is more than a Nairobi story: flooding affected counties from Migori to Makueni and Kwale, compounding the losses of homes, livestock and agricultural land. The financial fallout from floods has been staggering. A 2024 surge in floodrelated insurance claims underscored the scale of the problem, with insurers reporting billions of shillings in damages from homes, factories and infrastructure. High claims volumes have prompted insurers to tighten underwriting and reconsider coverage terms for properties in floodexposed zones. For homeowners and developers, this translates into higher premiums or, in extreme cases, difficulty obtaining coverage at all.

Rapid urbanisation has swallowed natural waterways and wetlands, encroaching on riparian land that once absorbed heavy rain. Nairobi's drainage systems - narrow, blocked or antiquated - were simply not designed to cope with the pounding downpours seen in 2026. A recent opinion from urban planners highlighted that flooding reveals decades of infrastructure lag, where heavy downpours regularly overwhelm the city's capacity to channel water, disrupt commerce, and expose public health risks. Architects and developers are also sounding the alarm. According to Dennis Njoroge Muchemi of Archilly Construction Ltd, flood resilience should be integrated into every project from the outset. "As architects, we are already exploring designs that incorporate vegetated terraces, permeable surfaces, and other features that slow runoff and enhance water absorption," he said. He noted that beyond these measures, architects are raising building foundations, creating stilts or elevated floors, and using floodtolerant materials like concrete and treated timber to withstand water damage. Rainwater harvesting systems, retention basins, and landscaped swales are being installed to manage excess water, while buffer zones along rivers and wetlands help protect properties naturally. "We are also repositioning structures to preserve natural water flow, ensuring that urban development works with, rather than against, the environment. These approaches are part of a broader push toward climatesmart, resilient construction in floodprone areas," he said. Kenya is far from alone in this reckoning. Across Africa and beyond, flooding is reshaping property markets - eroding values in riskexposed zones, pushing buyers toward higher ground, and prompting policymakers to rethink planning frameworks with resilience at the centre. In Nigeria's Lagos, one of Africa's fastestgrowing cities with a population exceeding 23 million, recurrent floods have begun to influence real estate market behaviour. Surveyor experts suggest that properties in highflood zones - including Lekki Phase 1, Ajah and parts of Ikoyi - have experienced price drops of between 12 per cent and 18 peer cent in resale value compared with homes in safer areas. A fourbedroom duplex that might have fetched sh20.3 million in 2021 is now selling closer to Sh17.6 million in floodprone localities, reflecting both reduced demand and actual water damage risk. At the same time, rental income in these zones is under pressure as tenants increasingly avoid groundfloor units, pushing vacancy rates up and weakening investor confidence. Insurance premiums in these highrisk areas have also soared more than 40 per cent since 2021, while developers face 10-15 per cent higher mitigation costs for new builds, further stressing profit margins. These trends echo broader academic findings on how flood risk affects home prices globally. Research shows that residential property prices in floodprone areas can be discounted by four per cent to 12 per cent relative to comparable unexposed homes, and following a significant flood event, values can plunge as much as 20 -32 per cent before gradually recovering over several years.

In Australia's South Australia, for example, nearly 160,000 homes at risk of flooding have collectively lost over Sh271.5 billion in combined value, with individual homes in highrisk zones trading thousands of dollars less than similar properties in safer areas. In Asia, recurring floods in regions like Pakistan's urban centres have damaged thousands of homes and shaken investor confidence, while in India's megacities such as Mumbai and Chennai, floodaffected neighbourhoods - particularly lowlying suburbs - have seen price growth lag behind that of elevated areas due to buyer preference for safety and futureproof investment. Even in Europe, the pattern is emerging. Recent studies in the Italian housing market show that areas with repeated flood exposure have experienced price declines of up to 4 per cent in frequently flooded regions, Across the United States - where severe weather and rising flood risk affect over 25 per cent of the nation's homes, representing more than USD 12 trillion in property value at risk - flood exposure is increasingly shaping homeowner and investor behaviour. Some 6 per cent of U.S. homes face extreme flood risk, and rising insurance premiums linked to climate hazards are increasing holding costs and affecting affordability in highrisk coastal communities. Research published in leading property economics studies also finds that higher flood risk scores can translate directly into lower asking prices: properties with maximum flood risk can trade at discounts exceeding 30 per cent compared with lowrisk homes, even when controlled for other features. In many markets, buyers are willing to pay premiums for higher ground and resilience features such as elevated foundations, engineered drainage systems and green buffers that mitigate flood impacts. In contrast, homes with perceived flood exposure are trading at discounts or stagnant prices, and lenders are tightening credit for properties they judge to have a heightened risk of future loss. For Kenya, where national price growth and rental yields still show positive fundamentals, this global context has direct implications. Climate risk is quickly becoming a differentiator in how value is measured, negotiated and protected. Homebuyers and investors alike are increasingly learning that understanding historic flood patterns and infrastructure quality is not optional - it's essential. Estate agents now advise buyers to observe neighbourhood performance during rains, check drainage, consult surveyors, and factor flood history into investment decisions. If floods were once a weather headline, they are now a market signal - one demanding stronger planning, smarter construction, and property decisions that value resilience as much as price. "The future of Kenya's real estate market will not be defined solely by location or price, but by climate resilience and adaptability," says Kagiri, echoing a perspective gaining traction across the industry.
