I think keeping investors interested in the UK property market as a whole is quite a difficult question to address.

Property in London, for example, is on an international stage and thus fuels investors interest naturally given the general ethos associated with investing in the capital.

In order to keep investors interested in the broader UK property market; a possible reduction in stamp duty land tax on multiple purchases, made within a 12 month period, could be implemented.

In order to increase interest across the UK as a whole the reductions could be staggered to reflect larger decreases in SDLT the further away from the capital, or major city, a property is situated. Or , implement a 'Zoning' system for SDLT reductions on multiple purchases.
