Best legal entity to whole land for later future development

Hi All,

I am considering buying some land in Chicago to hold for future development (likely not less than 2-years). The parcels are ready-to-build, with city services (power, sewage, etc) already available. But I want to wait until the neighborhood improves before committing resources to developing and building on the land.

What entity structure(s) would you recommend? Thanks in advance.
