If it is operated in the form of rent-for-purchase, the funds you mentioned are still quite sufficient.

The low yield is investment and financial management tools, such as insurance and national debt. Others live a mortgage life, buy houses around some universities, and then rent out their houses or run hotels to rent and raise houses. As a long-term investment, it takes little time and is worth considering.
