The prices of detached houses in Sweden have in recent decades shown a price development that has been record high. The purpose of this study is to estimate whether there is a significant relationship between different economic variables for detached house prices in Sweden's municipalities. The thesis was carried out through an economic multiple regression analysis with panel data where “fixed effect” was included. The study covers 289 municipalities in Sweden during the period 2001–2019 and the total number of observations is 5491. The study is carried out in the form of two analyzes where the variables supply ratio, income, unemployment, interest, population, tax and debt are included.

In the first analysis in 2001–2019, debt is excluded because there is no basis and lack of data. In the second analysis in 2010–2019, the purpose is mainly to estimate the relationship between price as the dependent variable and debt as the independent variable. The study is based on the first analysis to answer the research question: Factors that affect the price development for detached houses in Sweden.The result of the thesis shows that income is the variable with the most estimated correlation and impact on housing prices relative to the other independent variables.

The result also shows an expected positive relationship between the variable population and the detached house prices, as well as an expected negative relationship between the variables supply ratio, unemployment, mortgage interest, tax and debt on detached house prices. The study contributes to an increased understanding of how different economic factors affect the relationships for detached houseprices in Sweden's municipalities during the period 2001–2019. The study includes observations over a long period of time with a data base where there is no loss of observations. The validity of this study is based on the study's implementation and theoretical basis with authentic references.
