New vs. old construction: where are prices rising and what will happen in 2026?

A clear division is emerging in the Bulgarian housing market: on one side stand modern new complexes with energy-efficient facades and underground garages, and on the other – panel and brick buildings from the 70s, 80s, and 90s, often located in better-established neighborhoods. The question "new or old construction?" is increasingly deciding not just the interior, but the entire budget, quality of life, and resale prospects.

In recent years, the prices of newly built homes have grown faster than those of the old housing stock, and the demand for new construction is stable – especially in large cities. At the same time, statistics on actual transactions show that the majority of purchases are still in "old" homes. This creates a paradox – the new sets the direction for the market, but the old remains its backbone.

Where prices are rising faster

The dynamics during 2023–2025 show that it is new construction that is leading the growth. A number of analyses report that the prices of newly built homes are increasing by clear double-digit percentages on an annual basis, while the pace of appreciation for the old stock is lower. This confirms the trend of new projects "pulling up" average levels, especially in Sofia, Varna, Plovdiv, and Burgas.

At the end of 2025, the overall growth of housing prices in Bulgaria remains above the EU average, with the country ranking among the markets with the most dynamic price increases. Expert analysis emphasizes a "clear distinction between quality new buildings and aging housing stock" – it is in new projects that prices reach and surpass the highest levels for the respective cities, while old construction in the same neighborhoods remains noticeably cheaper.

The fact that the growth rate of new construction is higher does not mean that old homes are "lagging" completely. In well-positioned neighborhoods with developed infrastructure and limited supply, prices for the old stock are also rising, albeit more moderately, as the location compensates for some of the technical disadvantages.

Share of transactions: we buy more "old", but pay more for "new"

Although new buildings are in the spotlight, real transactions show that the old stock continues to dominate in terms of numbers. In recent years, approximately two-thirds of apartment transactions were in existing buildings, and about one-third – in new construction. That is, nearly three out of every four apartments sold in a typical year are in the old housing stock.

The picture changes when we look at the value of transactions. Approximate estimates show that despite the smaller number of deals, new construction accounts for a disproportionately large share of the total monetary value of the market. The average transaction price for new buildings is significantly higher, reflecting both more expensive square meters and larger mortgage loans.

In practice, purchases of new construction are fewer in number but more expensive. The old stock provides volume and liquidity – especially in well-developed neighborhoods – while new projects concentrate higher budgets and long-term financial commitments.

Prices and differences: new vs. old in numbers

Comparisons between new and old construction in large cities show a persistent price stratification. In Sofia, new apartments in the mass segment often start from levels significantly above those in old brick and panel buildings in the same or similar districts. In popular neighborhoods, new construction reaches and surpasses average prices that old buildings rarely reach, unless they offer an exceptionally good location or have already been renovated.

In Plovdiv, Varna, and Burgas, the picture is similar, albeit with lower absolute values: new complexes, especially in developing areas or near key infrastructure projects, command a premium over the old stock. In smaller towns, the price difference between new and old construction is smaller, but as a percentage, it often remains noticeable and influences buyer decisions.

For households, this means that the "new vs. old" choice is not just aesthetic, but also strategic: for the same budget, one can buy a larger property or a better location in the old stock, while new construction offers less area, but a more contemporary standard and lower maintenance costs.

Quality, energy efficiency, and "green" features

One of the key differences between new and old construction is energy efficiency. New buildings are as a rule designed with better thermal insulation, modern joinery, more efficient heating and cooling systems, and often with formal energy efficiency certificates. This lowers energy and maintenance bills and is becoming an increasingly important criterion for buyers against the backdrop of high price levels and European climate policies.

The old housing stock – especially panel blocks without major renovation – lags behind in this regard. Many owners face high heating costs, dampness, poor sound insulation, and depreciated common areas. Energy renovation programs partially mitigate the problem but are far from covering the entire stock. As a result, new construction is often perceived as "greener" and more sustainable in the long term, which justifies the higher price in the eyes of buyers.

In the higher segment, complexes with distinct "green" features are appearing – photovoltaics, rainwater systems, electric vehicle charging stations, and landscaped common areas. This attracts a younger and more demanding urban population that views a home not just as square meters, but as a complete ecosystem for living.

Buyer preferences: security of location vs. security of construction

When looking at buyer preferences, two main profiles emerge. The first seeks "new, modern, energy-efficient" – often young families or people with higher incomes who invest a significant percentage of their budget in a home with guaranteed quality, a parking space, and a well-organized environment. For them, the advantages are clean common areas, new installations, and the lack of need for immediate repairs.

The second profile prefers "old but secure" – established neighborhoods with built-up infrastructure, schools, transport, and green spaces, where new construction is less common or unaffordable. These are often families who want more space for the same money, or people who view the purchase as a flexible investment – a property that can easily be rented out or resold.

Between these two groups stands a significant number of buyers willing to compromise – for example, to choose an older property that has already been renovated, or a newer one in a peripheral area that is yet to be developed. It is precisely these compromises that often determine price dynamics in specific neighborhoods.

What to expect in 2026

In 2026, the housing market in Bulgaria will likely move at a more moderate pace compared to previous years, but the division between new and old construction will remain distinct. Overall price growth is expected to slow down compared to the peaks of 2023–2024, with base projections being for average annual appreciation in the range of a few percent, with higher values seen specifically in new construction in the most sought-after cities and neighborhoods.

New projects with good "green" characteristics, quality execution, and a convenient location will likely maintain their price advantage and remain the center of interest, even among more cautious buyers. At the same time, the old stock will continue to provide the majority of actual homes acquired, especially for households with limited budgets and those who prioritize location over the newest standard.

It is possible that in 2026, the "filtering" within the two categories will deepen. In new construction, projects weaker in quality or location will face stronger pressure for discounts and promotions, while the best ones will maintain their positions. In the old stock, properties in poor technical condition or in undeveloped areas may face difficulties in selling, while well-maintained and renovated homes will remain in demand.

For buyers, 2026 will be a year in which the slogan "new is always better" will be replaced by a more complex calculation: "what exactly am I getting for my money", "what are the long-term costs" and "how sustainable is this choice" – whether it is a new or an old building.
