A Miami real estate appraiser has pleaded guilty to wire fraud for her involvement in the Southwest Ranches-area fraud scheme in Broward County, the office of the U.S. Attorney for the Southern District of Florida said.

Martine Yanisse Castrillon is one of 15 defendants charged with buying homes through straw buyers at an inflated price, and then getting cash back at the closings. So far, nine defendants have pleaded guilty to various federal charges in the indictment.

Castrillon admitted that she did fraudulent appraisals -- valuing the properties at the amount requested by another defendant, not the true market price -- and forged the name of the certified appraiser who was to review her work.

According to the indictment, co-defendants Lazara Villalba and Henry Quintero-Lopez would offer the owner's full asking price and then inflate the contract purchase price to allow their companies, New World International and D&H Investments of South Florida, to receive a finder's fee, assignment fee or additional funds to allegedly construct improvements to the properties. They would then recruit individuals, who, for a fee, acted as straw buyers of the properties. Villalba and a co-defendant would obtain fraudulent pay stubs, IRS documents, verification of employment and verification of deposit forms; documents would be submitted to cooperating mortgage brokers and the loans were approved to purchase the properties.

Castrillon faces a maximum of 20 years in prison on each of the wire fraud counts and a fine of up to $250,000 on each count. Sentencing is scheduled for May 22.
