4M Properties of South Florida, LLC	Real estate	$500K–$1M	High	Report

Education, not investment advice. This is an estimate, not a holdings report. We start from the value ranges in the member's most recent financial disclosure and add or subtract later periodic transaction reports (PTRs). Disclosures give ranges, not exact values, and the result can be wrong: valuation dates differ, some trades can't be matched to a holding, and assets may have moved since. Confidence: High = taken directly from the report; Medium = changed by later trades or matched by name; Low = no stated value or unclear match.
