Will rising sea levels be a problem in the developed world sooner than we expect...
It's well known some mortgage companies won't lend on leasehold properties that have less than 60-70 years on their lease remaining. Could your seaside or riverside property be flooded in 60-70 years? How long before mortgage companies wake up to the fact that many freehold houses are really leasehold with Poseidon owning the lease? They could suddenly decide not to lend on such properties overnight. You might not have 60-70 years before the value is impacted.
