From the FBI Financial Crime Report Property Flipping
Property is purchased, falsely appraised at a higher value, and then quickly sold. What makes property illegal is that the appraisal information is fraudulent. The schemes typically involve one or more of the following: fraudulent appraisals, doctored loan documentation, inflating buyer income, etc. Kickbacks to buyers, investors, property/loan brokers, appraisers, title company employees are common in this scheme. A home worth $20,000 may be appraised for $80,000 or higher in this type of scheme.
Silent Second - The buyer of a property borrows the down payment from the seller through the issuance of a non-disclosed second mortgage. The primary lender believes the borrower has invested his own money in the down payment, when in fact, it is borrowed. The second mortgage may not be recorded to further conceal its status from the primary lender.
Nominee Loans/Straw Buyers - The identity of the borrower is concealed through the use of a nominee who allows the borrower to use the nominee's name and credit history to apply for a loan.
Fictitious/Stolen Identity - A fictitious/stolen identity may be used on the loan application. The applicant may be involved in an identity theft scheme: the applicant's name, personal identifying information and credit history are used without the true person's knowledge.
Inflated Appraisals - An appraiser acts in collusion with a borrower and provides a misleading appraisal report to the lender. The report inaccurately states an inflated property value.
Foreclosure Schemes - The perpetrator identifies homeowners who are at risk of defaulting on loans or whose houses are already in foreclosure. Perpetrators mislead the homeowners into believing that they can save their homes in exchange for a transfer of the deed and up-front fees. The perpetrator profits from these schemes by re-mortgaging the property or pocketing fees paid by the homeowner.
Equity Skimming - An investor may use a straw buyer, false income documents, and false credit reports, to obtain a mortgage loan in the straw buyer's name. Subsequent to closing, the straw buyer signs the property over to the investor in a quit claim deed which relinquishes all rights to the property and provides no guaranty to title. The investor does not make any mortgage payments and rents the property until foreclosure takes place several months later.
Air Loans - This is a non-existent property loan where there is usually no collateral. An example of an air loan would be where a broker invents borrowers and properties, establishes accounts for payments, and maintains custodial accounts for escrows. They may set up an office with a bank of telephones, each one used as the employer, appraiser, credit agency, etc., for verification purposes.
