Again, there's no magic formula, but each rental property investment type has its pros and cons: 1.) Single-family homes and duplexes: Stable income, predictable maintenance, good for beginners. But, higher upfront costs and potentially fewer tenants. 2.) Multi-unit buildings and student housing: Higher rental yields, but more management demands and tenant turnover. 3.) Short-term rentals and Airbnb: Flexible, potentially high returns, but require intense work and dynamic pricing strategies. Ultimately, the best choice depends on your budget, risk tolerance, and desired level of involvement.
