This data is contained in the Economic Experts Survey, a quarterly global survey carried out among experts in economics. They arise at a time when house prices slowed down to 8.7% in the first quarter of 2023, marking the smallest year-on-year increase since the 2nd quarter of 2021, as reported by the INE's Housing Price Index.

Portugal, which should see an increase of 8.2% per year in house prices over the next ten years, according to a report from CNN Portugal, is analyzed globally in conjunction with other countries in Southern Europe. As a whole, the surveyed economists believe that in this region the value of the sale of houses could rise between 10 and 15% in the next decade.

Even so, this “quite high” average for Southern Europe is mainly supported “by the expectations that economists have in relation to Malta, Serbia and Albania”, says Timo Wochner, a researcher at the IFO institute.
