There is, indeed, tens of thousands of empty homes in London. In a city with millions of homes. Current statistics show a vacancy rate of 2.2% [1], which is an incredibly low rate, which implies a pathologically supply-constrained market. Additionally, there is no evidence to support that even a statistically relevant proportion of those empty homes are empty for investment purposes; vacancies can happen for a number of reasons, including being between tenants, non-primary homes, etc.
