Why This Matters If You Are Buying in Greece
When you buy a property in Greece, the transfer tax is calculated on the property's value, and that value is the higher of the purchase price or the property's "objective value." So how the objective value is set has a direct effect on what you pay. Clearer, more consistent valuation rules mean you can be confident the tax is appropriate for the property. For investors, better valuation data also makes for more informed decisions.
What is "Objective Value"?
The objective value is the tax office's own estimate of what a property is worth, based on set criteria rather than the actual sale price. When you buy, the transfer tax is charged on the purchase price or the objective value, whichever is higher. The current transfer tax rate on an existing home is 3.09% of that value.
What is Changing
Greece is reforming how objective values are set, with the broad aim of bringing them closer to real market values and making the whole system more transparent. Two developments stand out. The first is a move towards a digital property value registry, through the valuemaps.gov.gr platform, intended to make valuation data available online. The second is that the official zone values, which sit at the heart of every objective value, were revised in 2025 and apply to 2026 taxes, with adjustments up or down depending on the area to better reflect current conditions. For buyers, the direction of travel is positive: a more digital, more transparent system that should make property values easier to understand and harder to dispute.
What Determines a Property's Value
These are the kinds of factors that feed into a valuation. It is not an exhaustive list, and the exact weighting varies.
Location
Usually the single biggest factor. Properties in tourist areas or near the coast tend to be worth more, while remote locations carry lower values.
Size and Usable Space
The floor area, layout, the floor an apartment sits on, recent maintenance, and whether it is furnished all play a part.
Age and Condition
Newer properties generally carry higher values, and older ones lower, though a well-renovated older home can be worth considerably more than a comparable un-renovated one.
Renovation and Development Potential
Whether you can extend the floor space, add a storey or a pool, can lift a property's value, as buyers pay for the ability to adapt a home. In Greece, the scope to extend can be limited by planning and forest regulations, so this is worth checking.
