The importance of the real estate market in the economy can be seen from several aspects. On the one hand, real estate represents a source of income for investors, that is, construction entrepreneurs, and on the other hand, it is an investment for the buyer that solves his housing problem or is a means of acquiring additional income. Oscillations in the real estate market in terms of supply and demand are diverse and depend on the general economic situation. It was precisely with the onset of the pandemic that certain changes in supply and demand took place. Research in the paper showed that in Croatia the construction industry faced challenges such as labor shortages and material price increases, but also had increased demand due to reconstruction after the earthquake.
