Sell property – Selling a condominium in Bonn is more demanding than many think: The former federal capital is among the most expensive real estate locations in North Rhine-Westphalia, with prices per square meter fluctuating between 4,500 € (Tannenbusch, Medinghoven) and over 8,000 € (Südstadt, Poppelsdorf, Bad Godesberg-Villenviertel), depending on the district. Anyone selling an apartment here must provide WEG-specific documents, calculate the speculation tax, consider tenant rights, and reach the right buyer group — end-users, investors, or institutional investors. This guide will walk you through all phases: from the rating to the marketing strategy (offensive, defensive, Off-Market) up to the notarial processing. Do you have little time or want to sell directly? Contact us — we also buy directly in NRW.
Bonn is A-location with stable demand: UN location, DAX corporations (Deutsche Post DHL, Telekom), university, federal authorities — the buyer potential is broad and affluent. However, the price range within the city is considerable, and exactly here, private sales make the most expensive mistakes: too high an asking price burns reach, too low a price gives away five- or six-figure amounts.
In Bonn, the micro-location determines up to 70 % price difference per square meter — even within the same district.

Bonn: Location in North Rhine-Westphalia
Here’s an overview of Bonn’s location — nestled between Cologne, the Rhein-Sieg district and the Siebengebirge mountains.
Sell privately or with a real estate agent — what’s more profitable in Bonn?
Both ways are possible. The question is not “what is better?”, but: What do they cost you in terms of time, mistakes, and an unmaximized selling price compared to the real estate agent’s commission?
Real Estate Agent Commission in NRW: What You Need to Know
Since the reform of the real estate agent law, NRW has been following the half-split principle: buyer and seller usually split the commission equally.
Usual total commission in Bonn: 7.14 % including VAT (3.57 % buyer / 3.57 % seller)
For an ETW for 500,000 €, this corresponds to 17,850 € seller share
The commission is only due upon notarial certification (success commission)
When selling privately makes sense
You have at least 4–6 months time for the entire process
You know the local Bonn market and your micro-location realistically
You can create a professional exposé with high-quality photos
You are strong in negotiations and conduct credit checks yourself
It’s about an “easily sellable” apartment in a solid location
When a real estate agent is worth it
Premium property in A-location (Südstadt, Poppelsdorf, Bad Godesberg) — price optimization over 17,850 € realistic
Rented apartment with complex tenant structure
Off-market sale to institutional investors desired
You live outside of Bonn or have no capacity due to professional commitments
Real estate appraisal: Determine the realistic purchase price
A professional appraisal is the basis of every serious sale. Gut feeling and ideal values either lead to holding out or to five-figure losses on the selling price.
Which appraisal method for condominiums?
Method
When to apply
Data basis
Comparison value method
Owner-occupied ETW (Standard)
Selling prices of comparable apartments, standard land value
Income value method
Rented ETW / Investment
Annual net cold rent, management costs, property interest rate
Asset value method
Rarely used for ETW (rather for single-family homes)
Construction costs minus depreciation
Value drivers for Bonn condominiums
Micro location: Street noise B9, view of the Rhine, proximity to Hofgarten/Kreuzbergpark
Floor & elevator: 4th floor without elevator = up to 15% price discount
Energy efficiency: Energy certificate from class E upwards has a noticeable negative impact today
Balcony, terrace, garden: Outdoor area is a major value driver in Bonn
Parking space / underground garage: in inner city locations adds 25,000–45,000 € value
Taxes when selling an apartment: Speculation tax & Co.
The biggest lever when it comes to taxes is the speculation tax according to § 23 EStG. Those who plan incorrectly here are giving away six figures.
Understanding the 10-year deadline
Apartment was purchased within the last 10 years → capital gain is fully taxed at the personal income tax rate (up to 45 % + solidarity surcharge)
Apartment owned for more than 10 years → tax-free sale
Exception for personal use: If the apartment was exclusively occupied by the owner in the year of sale and in the two previous years → tax-free, even within the 10-year period
Calculation example: Rented out ground floor apartment in Bonn-Südstadt
