Standard Compliance & Fraud Check
Real Estate Due Diligence

Turnkey Diligence delivers an Independent Certification of Completion of A Compliance & Fraud Risk Review after each Standard Compliance & Fraud Check.

Each project focuses on: (i.) Compliance Checks - where we look for corruption or compliance problems with the other people involved in the deal; and (ii.) Fraud Checks - where we look for signs that you are being scammed.  This is a basic level check designed to satisfy FinCEN, FCPA, and other regulatory requirements,  These checks are also used for fraud risk analysis, especially on cash deals. 

Compliance Checks include database and records research to identify indicators of money laundering that could get you into legal trouble, including the hidden interests of sanctioned foreigners.  Fraud Checks include unannounced site visits to the property and government offices looking for information that a standard appraisal or document review may overlook.  Final reports include an executive summary and a risk score, detailed results of the diligence activities, and brief recommendations.
