Starting small with multifamily properties is my ideal preference at the moment, as I focus on learning, growing, and immersing myself in as much information, data, and real-time experience as possible.As I build my investment portfolio, I could definitely see myself being interested in scaling up to larger acquisitions in the future, but for now, my focus is on mastering the fundamentals and starting small.
