Investing In Portugal: Four new developments in Portugal, two on the Algarve and two near Lisbon, are being launched in the Four Seasons Hotel in Ballsbridge, Dublin 4, this weekend.

The two on the Algarve are the Vale Santo Antonio - where a mix of apartments, townhouses and villas in a resort near Quinta do Lago will cost from €500,000 - and Monte Santo Resort in Carvoeiro, where two and three-bedroom townhouses will cost from €405,000.

The two developments near Lisbon are Troiaresort, where apartments by a beach south of Lisbon (a 30-minute drive on the motorway, according to the agents) will cost from €205,000; and Quintas de Óbidos Country Club, near Lisbon on Portugal's "Silver Coast", where custom-built villas cost from around €1.375 million.

The four developments are being sold through IRG Portugal, Christies Great Estates and Ganly Walters.
