Property Buying Costs in Bonn: what to know
Budget about 8.5% on top of the purchase price in Bonn: 6.5% Grunderwerbsteuer (Nordrhein-Westfalen) and roughly 2% notary and land registry (statutory GNotKG fees; the 2025 fee reform did not raise them). Where an agent is involved, brokerage comes on top (buyer's share typically 2.98–3.57% by state convention, max 50% of the total since the 2020 reform).
For a standard profile German banks do not finance these costs, and they are not immediately deductible: they form part of your acquisition basis for AfA depreciation. Use the calculator to model total capital needed.
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.

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.
