As an AI language model, I do not have personal opinions and cannot provide financial or investment advice. However, here are some common real estate investment strategies to consider diversifying your portfolio:

1. Rental Properties: purchasing residential or commercial properties for the purpose of renting them out to tenants.
2. Flipping Properties: purchasing distressed or undervalued properties, renovating them, and selling them for a profit.
3. REITs: investment in Real Estate Investment Trusts, which are companies that own and manage income-producing real estate properties.
4. Crowdfunding: investing in real estate projects and properties via online platforms where multiple investors pool their money together.
5. Equity Investment: investing in real estate by purchasing shares of ownership in a property or portfolio of properties.
6. Private Lending: lending money to real estate investors and receiving interest payments rather than owning property.
7. Lease Options: leasing a property with an option to purchase it at a pre-agreed price in the future.
8. Development: investing in the development of new properties.
9. Tax Liens: investing in property tax liens that allow for the purchase of a property at a discounted price.
10. Foreign Real Estate: investing in real estate markets outside of one’s home country.
