Anyone who sells without an estate agent saves the commission—but also bears sole responsibility for every step. This is exactly where costly mistakes happen: An excessively high price, an incomplete property brochure or an unchecked buyer can quickly cost more time and money than an estate agent ever would. We show you the most common pitfalls when selling privately and how to avoid them from the outset.
Why Particularly Many Mistakes Happen When Selling Privately
When selling without an estate agent, you take on all the tasks that a professional would otherwise handle: valuation, property brochure, marketing, viewings, price negotiations and preparation for the notary appointment. There is no obligation to involve an estate agent—the only mandatory requirement is notarisation of the purchase agreement (§ 311b BGB).
The reward is the commission saved: It is usually between 5 and 7 percent of the purchase price including VAT and, since December 2020, is generally shared between the buyer and seller (§ 656c BGB). Anyone who wants to benefit from this saving must know the mistakes that slow down or increase the cost of the sale. The following nine are the most common.
The Most Common Mistakes When Selling Without an Estate Agent
Mistake 1: A Price That Does Not Match the Market
The asking price is the biggest lever—and the most common source of mistakes. A price that is too high scares off potential buyers; the property becomes a slow seller, and later price reductions signal that something is wrong. A price that is too low gives away cash. Use the standard land value, current comparable listings in your location and—in case of doubt—a professional short valuation report as a guide, instead of estimating based on intuition.
Mistake 2: Poor Photos and a Thin Property Brochure
Whether buyers are interested or click away is often decided by the very first photo. Dark, shaky mobile-phone pictures, cluttered rooms and a property brochure without a floor plan cost you the best prospects. Take photos in daylight, tidy up beforehand and provide all the key details: living space, year of construction, floor plan and an honest description. A well-prepared property brochure looks professional and saves you many follow-up questions later.
Mistake 3: Forgetting Mandatory Information About the Energy Performance Certificate
As soon as a valid energy performance certificate is available, the listing must already contain certainInformation included: the type of certificate, the final energy demand or consumption, the main energy sources, the year of construction and the energy efficiency class (§ 87 GEG). If this information is missing, this constitutes an administrative offense punishable by a fine of up to 10,000 euros—and warnings may also follow. You must present the certificate itself no later than during the viewing and hand it over after the sale.
Mistake 4: Concealing known defects
Many private sellers agree on an exclusion of liability for defects (“bought as seen”) and feel they are on the safe side. This is a mistake: You cannot invoke such an exclusion if you fraudulently concealed a defect (§ 444 BGB). Known defects that are material to the purchase decision—for example, a damp basement, mold or contaminated sites—should be disclosed openly and, ideally, included in the contract. Anyone who conceals them risks having to pay damages or having the entire purchase rescinded.
Mistake 5: Not checking the buyer’s creditworthiness
Nothing is more frustrating than taking the property off the market for an interested party who ultimately cannot pay. Before accepting the offer, ask to see an objective, property-specific financing confirmation from the bank or a current self-disclosure. Check that the documents are originals, bear the correct name and are dated no more than two weeks ago. This prevents the sale from falling through shortly before the notary appointment.
Mistake 6: Entering negotiations emotionally
Your property is associated with memories for you—for the buyer, it is a number. Anyone who takes offers personally negotiates poorly. Set a minimum price in advance, have your arguments regarding location, condition and modernizations ready, and separate feelings from facts. A matter-of-fact negotiation almost always leads to a better result.
Mistake 7: Compiling documents too late
Missing documents delay the sale and make buyers view you as unprofessional. Obtain the current land register extract, floor plan and energy certificate before the first listing. For a condominium, the declaration of division, the minutes of the most recent owners’ meetings, the budget plan and the amount of the maintenance reserve are also required. Anyone who has these documents readily available appears prepared and speeds up the closing.
Mistake 8: The Underestimating the notary appointment and the contract
The notary notarizes the purchase agreement neutrally – they advise neither you nor the buyer strategically. Therefore, read the draft thoroughly and clarify payment security, the handover date and meter readings. Give the buyer the draft in good time: If a consumer buys from a business, the text generally must be available two weeks before notarization (§ 17 para. 2a BeurkG). Even when selling privately to a private individual, this period is a fair standard that helps avoid disputes.
Mistake 9: Overlooking taxes and deadlines
If you sell a rented or vacant property within ten years of purchasing it, the profit may be subject to speculation tax – at your personal income tax rate (§ 23 EStG). The sale remains tax-free if you occupied the property yourself in the year of the sale and the two preceding years. Check this period before listing: Sometimes postponing the sale by a little can save several thousand euros.
Advantages and disadvantages of selling without an agent
Whether a private sale is worthwhile depends on your time and your market. You should weigh these points:
- Advantage – cost savings: You save the share of the commission, which can amount to several tens of thousands of euros for higher purchase prices.
- Advantage – full control: You know your property best and manage the price, appointments and communication yourself.
- Advantage – direct contact: You speak directly with prospective buyers and can respond to questions immediately.
- Disadvantage – time required: Marketing, viewings and negotiations take a noticeable amount of time.
- Disadvantage – lack of market experience: Assessing the price and negotiations realistically is difficult without experience.
- Disadvantage – legal pitfalls: Errors in mandatory information or in disclosing defects can become expensive.
FAQ about selling without an agent
What is the most common mistake in a private sale?
Setting the wrong price. An asking price that is too high makes the property a slow seller, while one that is too low gives away money. A realistic valuation based on the standard land value and comparable listings is therefore the most important decision point.
Do I have to disclose defects even if I exclude liability?
Yes. A disclaimer of liability does not protect you if you are aware of a material, known Fraudulently concealing a defect (§ 444 BGB). Disclose known defects and record them in the purchase agreement.
Which energy details are mandatory in the listing?
If an energy performance certificate is available, the certificate type, final energy demand or consumption, main energy sources, year of construction and energy efficiency class must be included in the listing (§ 87 GEG). Missing information may result in a fine.
How do I check whether a buyer is financially capable of paying?
Ask for a property-specific financing confirmation from the bank or a current self-disclosure. You should only be shown originals that are no more than two weeks old.
When does speculation tax become payable on a sale?
If less than ten years pass between the purchase and sale and you have not lived in the property yourself (§ 23 EStG). If you have continuously used the property yourself in the year of sale and the two preceding years, the profit remains tax-free.
