It’s clear that there’s an incredible wealth of knowledge and experience here, and I’m excited to continue learning and growing with this community.I’m looking to connect with members who are open to mentoring or collaborating on real estate deals, particularly in buy-and-hold strategies for single-family or multi-family properties.
