Selling a home is a complex, emotionally and financially demanding process that goes far beyond the confines of a typical transaction. A common, yet costly, mistake is thinking that simply posting an ad and passively waiting for a buyer. However, the market reality can be much more demanding, and success depends on a methodical approach and thorough preparation at every stage.

This article is a comprehensive guide that will guide you through the entire, often complicated, process of selling real estate – from the initial analyses and preparations, through marketing and negotiations, to finalization at the notary and post-transaction obligations.


How to sell an apartment?

The success of the entire transaction depends largely on a solid foundation. Neglecting the initial stages can lead to a prolonged process, the need to lower the price, or, in the worst-case scenario, serious legal issues. So, how can you sell your apartment thoughtfully and strategically?

Step 1: Preparing the property for sale – from cleaning to home staging

A potential buyer decides whether they’re interested in a property within the first few seconds, often based on online photos ; first impressions are therefore decisive and unique. The aesthetic and functional design of the apartment is therefore absolutely crucial.

The process should begin with the basics: a thorough cleaning, depersonalization of the interior, and minor but significant repairs if necessary. A leaky faucet, a squeaky door, or a burned-out light bulb are all minor details that can effectively discourage a buyer, creating a subconscious image of a neglected property requiring significant financial investment.

Then it is worth using home techniques Staging is the strategic preparation of a home for sale, involving neutral design, functional furniture arrangement, and subtle décor changes to make the interior welcoming, spacious, and aesthetically pleasing to the widest possible audience. Home staging has a powerful psychological impact on buyers, evoking positive emotions and helping them imagine themselves in the space.

  • DIY Home Staging : no major investment required. Sometimes simple tricks are enough: new, neutral textiles (pillows, curtains), strategically placed lamps that create a warm atmosphere, fresh flowers, or minimalist decorations. Smell is also important – the aroma of freshly brewed coffee or a baked cake works wonders.
  • Virtual Home Staging : for empty apartments or those requiring renovation, a perfect alternative is virtual staging, which shows the potential of the interior through visualizations.

This stage culminates in a professional photography session and the preparation of a floor plan . Good photos enhance the effect, presenting the space in its best light, and a clear floor plan is now standard, significantly increasing the attractiveness of the offer.

Step 2: Realistic Pricing – The Key to Attracting Buyers

Determining the appropriate asking price is one of the most difficult and simultaneously crucial decisions. An incorrect valuation—whether too high or too low—inevitably leads to losses. An inflated price will deter potential customers and cause the offer to languish on the market for months, losing credibility and becoming a “spot on the wall.” An underpriced price, on the other hand, translates into direct financial loss.

To properly value your property, you must:

  • Conduct a comparative market analysis: carefully analyze the transaction prices (not offer prices!) of similar properties in the same location, taking into account the square footage, finishing standard, floor, technical condition of the building and access to infrastructure.
  • Enlist the help of a real estate appraiser: For unusual or high-value properties, it’s worth considering having a professional prepare a valuation report . This official document serves as a powerful argument during negotiations.

The pricing strategy should include a negotiating margin, typically 5-10% of the target price. This gives the buyer a sense of success and allows the seller to achieve their financial goal.

Step 3: Completing documentation and formal issues

Before an offer hits the market, all necessary documents must be gathered. Failure to do so could delay or even prevent the transaction. The basic package includes:

  • Basis for acquiring real estate: Notarial deed of purchase, donation or court decision confirming the acquisition of inheritance.
  • Land and mortgage register number: Enables verification of the legal status of the property.
  • Certificate of no arrears in fees from a housing cooperative or community.
  • Certificate of no registered persons.
  • Energy Performance Certificate: As of April 2023, this document is mandatory for all sales or rentals. It determines the building’s energy requirements, and failure to submit one with the notarial deed may result in a fine.

Sale of an apartment with a mortgage

This is a very common scenario that requires additional formalities. You must obtain a certificate from the bank confirming the current debt balance and a promise to cancel the mortgage upon full repayment of the loan. On the transaction date, a portion of the buyer’s funds is transferred directly to the bank’s technical account to repay the mortgage, while the remaining amount is transferred to the seller’s account.


Financial and marketing aspects – how to earn and not lose?

Once the foundations are in place, it’s time to understand the full financial picture and effectively reach potential buyers.

Step 4: Tax Issues and Transaction Costs

Selling a home comes with costs that should be kept in mind when budgeting. The seller typically bears the following costs:

  • Remuneration for the real estate agency (if using its services).
  • The cost of preparing an energy performance certificate (several hundred zlotys).
  • Costs of obtaining necessary certificates.
  • Costs of extracts from the notarial deed (usually the notary fee is paid by the buyer, but the parties may agree otherwise).

The most important issue, however, is income tax . The seller must pay 19% income tax (the difference between the selling price and the acquisition cost) if the sale occurs within five years of the end of the calendar year in which the purchase occurred. However, it is possible to be exempt from this tax thanks to the so-called housing tax relief . The condition is that the proceeds from the sale are used for personal housing purposes (e.g., purchasing another property, building a house, repaying a loan) within three years of the end of the tax year in which the sale occurred.


Finalizing the process – from presentation to handing over the keys

The final stage is a straightforward path to closing the transaction, but it requires interpersonal skills and knowledge of legal procedures. After successful negotiations, the parties typically sign a preliminary agreement . This protects the interests of both parties and constitutes the moment of payment of a specified sum. However, it is important to understand the fundamental difference between a deposit and an advance payment.

  • The advance payment is part of the price and is refundable in the event of non-fulfilment of the contract. It is less binding.
  • The deposit (regulated by the Civil Code) serves a disciplinary purpose. If the transaction fails due to the buyer’s fault, the deposit is forfeited to the seller. If it is due to the seller’s fault, the seller must return double the deposit to the buyer .

Step 5: Final Notary Office and Post-Sale Obligations

The transaction is finalized at the notary’s office by signing a notarial deed of sale . After the deed is signed and payment is made, the final step is the physical handover of the property, which must be documented with a handover protocol . The protocol records meter readings (electricity, water, gas) and describes the technical condition of the apartment and the transferred furnishings.

But that’s not all. After the sale, there are a few formalities to complete:

  • Check out of the premises.
  • Report the sale to the cooperative or housing community.
  • Terminate contracts with utility suppliers (electricity, gas, internet ) or transfer them to a new owner.
  • Report the sale to the city/municipality office to stop paying property tax.

Selling a home is a marathon, not a sprint. Every step is crucial to the final outcome. Systematic and thoughtful action not only maximizes profit but also minimizes stress and ensures complete security of the entire transaction. With proper preparation, this complex process can become much simpler and ultimately successful.
