It depends on how long you plan to stay and how prices compare with rents. Because you first need to earn back the buying costs, buying in Berlin usually beats renting after 3,5–5 years.

Signs that buying makes sense for you:

• You plan to stay at least 5 years
• The purchase price is less than about 25 times the annual rent for a similar apartment
• Your monthly mortgage payment would be close to your current rent

Compare both options with the rent or buy calculator and read Rent or buy in 2026. Your monthly payment depends on today’s mortgage rates.

Many inner-city Berlin neighbourhoods are social protection areas (Milieuschutzgebiete), and Berlin now has more than 70 of them. The Senate’s Geoportal map shows the exact boundaries street by street.

What it means if you buy there:

• Buying an existing condo and moving in isn’t affected
• Upgrades such as a second bathroom or merging two apartments need a permit
• Converting rental buildings into condos needs a permit and is largely banned until at least the end of 2030
• The district’s right of first refusal has rarely been used since a 2021 federal court ruling
