The big data consulting firms seem to be out ahead of the academic researchers:
Real estate agents looking to sell coastal properties usually focus on one thing: how close the home is to the water’s edge. But buyers are increasingly asking instead how far back it is from the waterline. How many feet above sea level? Is it fortified against storm surges? Does it have emergency power and sump pumps?
Rising sea levels are changing the way people think about waterfront real estate. Though demand remains strong and developers continue to build near the water in many coastal cities, homeowners across the nation are slowly growing wary of buying property in areas most vulnerable to the effects of climate change.
A warming planet has already forced a number of industries — coal, oil, agriculture and utilities among them — to account for potential future costs of a changed climate. The real estate industry, particularly along the vulnerable coastlines, is slowly awakening to the need to factor in the risks of catastrophic damage from climate change, including that wrought by rising seas and storm-driven flooding.
But many economists say that this reckoning needs to happen much faster and that home buyers urgently need to be better informed. Some analysts say the economic impact of a collapse in the waterfront property market could surpass that of the bursting dot-com and real estate bubbles of 2000 and 2008. ...
Over the past five years, home sales in flood-prone areas grew about 25 percent less quickly than in counties that do not typically flood, according to county-by-county data from Attom Data Solutions, the parent company of RealtyTrac. Many coastal residents are rethinking their investments and heading for safer ground. ...Banks and insurers need to protect their collateral and investors more by improving their methods for estimating climate-change risks and creating more standardized rules for reporting them publicly, economists warn.
In April, Sean Becketti, the chief economist for Freddie Mac, the government-backed mortgage giant, issued a dire prediction. It is only a matter of time, he wrote, before sea level rise and storm surges become so unbearable along the coast that people will leave, ditching their mortgages and potentially triggering another housing meltdown — except this time, it would be unlikely that these housing prices would ever recover. ...
In the past year, home sales have increased 2.6 percent nationally, but have dropped about 7.6 percent in high-risk flood zones in Miami-Dade County, according to housing data. Many coastal cities are taking steps toward mitigation, digging runoff tunnels, elevating roads and building detention ponds.
But here is a new paper that is finding some impact of Hurricane Sandy on housing prices: Rising Sea Levels and Sinking Housing Prices. This literature is likely a growth area unless I'm missing something (i.e., please add references in the comments section).
