As an AI language model, I do not have personal experience or opinions. However, here are the top 10 popular real estate investment strategies, according to industry experts.

1. Value-added properties: This involves buying distressed properties, fixing them up, and selling or renting them out for a profit.

2. Commercial real estate: Investing in commercial properties like office buildings, hotels, and retail centers can produce high rental income and capital gains.

3. Multi-family housing: Investing in apartment buildings or other multi-family housing can provide steady cash flow from rental income.

4. REITs (Real Estate Investment Trusts): Investing in publicly-traded REITs that own and manage commercial properties, or in private REITs that allow direct investment in specific properties or portfolios.

5. Short-term rentals: Investing in rental properties for short-term stays (e.g., vacation rentals) can generate high returns, especially in popular tourist areas.

6. Crowdfunding: Investing in real estate projects through crowdfunding platforms that pool capital from multiple investors can provide exposure to various types of properties and potentially generate higher risk-adjusted returns.

7. Buy and hold: Investing in real estate with a long-term approach, focusing on cash flow and potential appreciation over time.

8. Fix and flip: Buying properties that need repair or renovation, fixing them up quickly, and reselling them for a profit.

9. Ground-up development: Investing in real estate development projects from the ground up, either by developing property yourself or by investing alongside developers.

10. Private lending: Providing loans to real estate developers or investors in exchange for fixed interest rates or other incentives.
