According to Bolgarskiydom (EN section), citing the national statistics office NSI, Bulgaria's house price index rose 6.2% quarter on quarter and 14.8% year on year in the first quarter of 2026.
According to Bolgarskiydom (EN section), which cites an NSI release dated 24 June 2026, Bulgaria's house price index grew 6.2% quarter on quarter and 14.8% year on year in the first quarter of 2026. The article stresses that this is an index of price change in registered household transactions. It is not an average price per square metre and not a forecast of where the market goes next. For the largest cities, the quarterly figures published by NSI were: Burgas +5.9%, Sofia +5.8%, Varna +4.0% and Plovdiv +3.9%. The article also presents a table of overall figures by city and by segment: Sofia 16.0% (new dwellings 16.2%, existing 15.8%), Plovdiv 8.8% (1.9% and 15.2%), Varna 13.2% (4.5% and 17.0%) and Burgas 17.7% (25.8% and 13.0%). NSI calculates each city's overall figure as a standalone index rather than a simple average of the new and existing segments. The source cautions that a city-wide percentage cannot be applied to a single apartment: the index does not explain the reasons for the change, the stage of a given development, or the liquidity of a particular unit. For context, it recalls that in January 2026 BTA reported an analyst's forecast of a 5–10% rise nationwide and 8–12% in Sofia. That is an attributed market forecast, not NSI data, and it is not directly comparable with a first-quarter year-on-year index because the horizons and methods differ.
