You can invest in real estate with minimal capital through options like publicly traded REITs, crowdfunding platforms, house hacking, wholesaling, and seller financing. REITs offer liquidity and income without control, while crowdfunding pools funds for managed projects. House hacking involves living in part of a property and renting out the rest to offset costs. Wholesaling requires contracts and market knowledge, and seller financing allows direct payments to sellers. Research and legal review are essential to manage risks and ensure profitable investments.
