Sam Primm explains that his first million was built through single-family rental investing, allowing equity to accumulate over time as properties appreciated and tenants paid down the mortgages. He says his last million came from apartment investing, where larger deals enabled him to scale and grow wealth more rapidly. Looking ahead, Sam expects his next million to come from the lending side of real estate, either by connecting capital with borrowers through his platform or by launching a fund that facilitates those transactions.
