Buy Apartment (Expat) in Bonn: what to know
Thousands of international professionals live in Bonn, and none of them need German citizenship to buy. Residents with German income get near-domestic financing terms; Blue Card holders are treated like locals by most banks after probation.
The binding step is the notarised contract: the notary is neutral, and you may demand the draft 14 days in advance and bring an interpreter. Read the Teilungserklärung, Hausgeld statements and WEG minutes before you sign.
The Bonn market in numbers
Bonn (Nordrhein-Westfalen) has 340,226 residents. Existing apartments average around €4,460/m² (citywide range roughly €2,900–€6,630/m²), with new-builds at about €6,120/m². Average asking cold rent is about €14.25/m², putting the gross rental yield near 3.8%.
Price momentum: +1% year-on-year. After the 2022/23 rate-shock correction (existing-flat prices -4.9% in 2024 vs 2023 per KAMPMEYER), prices stabilised and turned slightly positive: Q1 2025 avg 3,905 EUR/m² vs 3,865 EUR/m² in Q1 2024 (+1.0%). Existing-flat prices rose from ~3,200 EUR/m² (2021) to ~3,650 EUR/m² (2024), new-build from ~5,000 to ~6,120 EUR/m²; asking rents rose ~18% 2021–2024 and +5.2% in 2025 alone.
Vacancy: roughly 0.9% (Wüest Partner, Wohnungsmarkt NRW, 2023). That is effectively full occupancy: supply scarcity drives both rents and letting speed.
Where to buy in Bonn
Südstadt, Poppelsdorf and Zentrum trade clearly above the city average; that is where investment demand concentrates. Value- and yield-oriented buyers look at Hardthöhe and Beuel, which trade clearly below the city average, where gross yields are usually higher and management takes more work.
Südstadt: Bonn's most prestigious quarter with one of Germany's largest intact Wilhelminian (Gründerzeit) townhouse ensembles, next to the university and Rhine promenade. Apartments trade around €5,200–€6,360/m².
Poppelsdorf: Sought-after academic quarter around Poppelsdorf Palace and the botanical gardens, mixing period buildings with student and professional demand; commands Bonn's highest rents (~15 EUR/m²). Apartments trade around €4,880–€6,070/m².
Bad Godesberg: Former diplomatic quarter in the south with villa districts, international schools and UN-related expat demand, at more moderate average prices than the centre. Apartments trade around €3,810–€4,810/m².
Beuel: Up-and-coming right-bank district across the Rhine with good value, riverside location and strong new-build activity. Apartments trade around €3,960–€4,370/m².
Zentrum (Stadtbezirk Bonn): The central city district including Altstadt and Nordstadt, combining offices, retail and dense period housing; existing stock is mid-priced while new-build tops 6,000 EUR/m². Apartments trade around €3,530–€6,030/m².
Hardthöhe: Modest western district dominated by the Federal Ministry of Defence campus and post-war housing; the cheapest entry point in the city. Apartments trade around €2,900–€3,690/m².
Taxes & buying costs in Bonn
Property transfer tax (Grunderwerbsteuer) in Nordrhein-Westfalen is 6.5%. Add approximately 2% for notary and land registry (statutory GNotKG fees), so purchase costs come to about 8.5% of the price; buying through an agent adds the buyer's commission (typically 2.98–3.57%). For a standard profile German banks do not finance these costs.
Held privately, the property can be sold tax-free after the 10-year Spekulationsfrist; before that, gains are taxed at your personal rate. Depreciation (AfA) shelters rental income: 2% p.a. for buildings completed 1925–2022 (2.5% before 1925), 3% for buildings completed from 2023, and qualifying new projects started between October 2023 and September 2029 can choose 5% degressive depreciation instead of the linear rate.
General information, not tax advice; LDP Group gives no tax advice.
Bonn is a designated tight housing market: the Mietpreisbremse caps new-lease rents at roughly 10% above the local comparative rent (Mietspiegel), and the reduced Kappungsgrenze limits in-tenancy increases to 15% within three years. Factor the achievable regulated rent, not the asking-rent headline, into your underwriting.
