Jeff Conry and 6312 Riviera Drive, Coral Gables (Google Maps, iStock) The president of a charter airline flipped his waterfront Coral Gables mansion for $19.4 million, pocketing a tidy profit less than a year after he purchased the property. Jeff Conry of iAero Airways and his wife, Sherianne, sold the home at 6312 Riviera Drive, records show. The buying entity — Registered Corporate Services LLC — is managed by Pablo S. Quesada and Roland Sanchez-Medina, both partners at Coral Gables-based SMGQ Law. The LLC took out a $13.4 million loan on the property from City National Bank of Florida, according to records. Mocca Realty’s Diana Gutierrez represented the sellers and Alex Pirez — also of Mocca Realty — represented the buyer.
