Return On Investment (Definition, Example)| How to Interpret ROI? Investing in London has the potential to be very profitable. In terms of real estate and property, London is a prime location to purchase land. That is because the real estate market is very stable here. Even though recessions, such as the one in 2008-9, the London real estate market was able to quickly recover. This is evident through the lack of defaults on mortgage loans in the UK, as it happened in the US (Coobrick). According to Coobrick Property Consultants, the average cumulative return on investment for commercial property in London is 12.7%. With profitability this high, it will be possible for us to expand and find real estate value in other regions and countries.
