Spear’s Review

Sophie Panizzo, director of boutique buying service Argentum Property, is a seasoned operator who helps to connect HNW clients to their dream homes in London while also opening up the prime property market in Portugal’s capital city to international buyers.

Her firm works with Lisbon’s leading developers to help clients find homes tailored to their own needs and specifications, with the firm typically sourcing properties valued between £500,000 and £2.5 million. She launched the Mayfair-based enterprise with fellow agent Luis Diez de Oñate in 2016.

Panizzo previously headed Sterling Advisory’s central London office and oversaw Sotheby’s International Realty’s operations in Chelsea.
