As the UK’s housing market goes in to reverse, property search startup Nestoria is looking overseas for growth. Founded by former Yahoo (NSDQ: YHOO) execs Javier Etxebeste and Ed Freyfogle under their Lokku company, Nestoria will today announce a partnership with Spanish regional publisher Vocento, which has the popular freesheet Que in its portfolio. At the same time, it’s launched an Italian site, partnering for classifieds with publishers like 123Case,  Casa.it, Idealista, Repubblica, Casaclick, Immobiliare, and Trovocasa.
