If you are thinking about selling a house privately, you have probably already realised that it is not as simple as publishing a listing and waiting for a buyer to appear.
There is paperwork to prepare, important decisions to make and a series of steps worth following to avoid mistakes that could delay the sale or create problems later on.
The good news is that more and more people complete a private property sale without using an estate agent. That gives you more control over the whole process, lets you negotiate directly with the buyer and helps you avoid commissions that can amount to a significant sum of money.
That said, selling a property without intermediaries does not mean doing it without support. If you want to manage the whole transaction in an organised way, from preparing the documents to the final signing, you can do it with Firma Vivienda. Our platform is designed to help you sell your home more easily and with the support you need at each stage.
You can also manage the full private property sale from one place and review how Firma Vivienda works before getting started.
Prepare the sale of your property
Before publishing the property or starting to receive calls, it helps to organise the whole preparation stage properly.
A well-prepared sale saves time, creates trust and avoids many of the bottlenecks that appear when a genuinely interested buyer shows up.
Gather all the paperwork before you start
One of the biggest mistakes when selling a property is waiting until you have a buyer before looking for the paperwork.
When someone is genuinely interested in buying, they usually ask for information and documents very early. If it takes you days or weeks to gather them, the transaction can cool down.
That is why it is best to get ahead of it. Before putting the property on the market, it is advisable to locate the title deed, request an updated land registry extract, check whether there are charges or outstanding mortgages and have the relevant energy certificate ready.
Having the documents prepared builds trust and shows that the transaction is properly organised from the start.
If you have questions on this point, it helps to read our guide on documents needed to sell a house, where we explain which papers are usually requested and why they matter.
Set a realistic asking price
One of the factors that most influences the success of a sale is the asking price.
Many owners value their property based on emotional attachment or on the money they have invested over the years. The market, however, works differently.
The buyer will compare your property with similar homes available in the area. If the price is too far above the market, they may not even visit it.
That is why it makes sense to analyse comparable homes, review recent transactions and set a competitive price from the beginning.
A well-adjusted price usually leads to more visits, smoother negotiations and a much faster sale.
Prepare the property for viewings
When someone visits a house, they are not only assessing square metres or layout. They are also imagining what it would be like to live there.
That is why presentation matters. This does not necessarily mean carrying out major renovations. Often, better lighting, tidier spaces, minor repairs or clearing certain rooms is enough to make the property much more appealing.
A strong first impression can be the difference between just another viewing and a serious offer.
Negotiation and agreements with the buyer
Once the property starts receiving genuine interest, a decisive stage begins: negotiation.
Here, it is not only the price that matters. Timing, financing and the conditions each side is willing to accept also play an important role.
Negotiate directly with the buyer
One of the most interesting advantages of a private sale is that communication is direct.
There are no intermediaries filtering information or relaying messages from one side to the other. You can speak directly with the interested buyer and resolve doubts immediately.
Even so, it is worth being clear on a few points before negotiating:
- the minimum price you are willing to accept
- the timeline you can realistically handle
- the real situation of the property
- the conditions you consider essential
Having these points clear will help you negotiate more calmly and avoid rushed decisions.
The earnest money contract: the first major commitment
When buyer and seller reach an agreement, the next step is usually signing the earnest money contract.
This is one of the most important documents in the process, although many people underestimate it. It sets out the terms of the transaction, the planned timing for going to the notary and the consequences of a possible breach.
That is why it is not advisable to rely on any random internet template.
If you want to see how this document should be structured, you can review our earnest money contract template. It also helps to read this guide on what must be included in an earnest money contract, because a poorly drafted clause can create serious problems later.
Check the buyer's financial position
Many transactions depend on the buyer obtaining a mortgage.
And this is where one of the most common problems in property sales appears: the buyer signs the earnest money contract convinced they will secure financing, but weeks later the bank refuses the mortgage.
That is why it is important to talk about this from the start and reflect the situation properly in the contract.
If you want to understand this scenario better, you can read our guide on what happens if the bank does not approve the mortgage after signing an earnest money contract, where we explain what can happen and how to protect yourself properly.
Formalising the sale
Once there is an agreement, the paperwork is ready and the financing is reasonably clear, it is time to prepare the final stretch.
This is the stage where the benefits of a well-organised transaction become most visible.
Organise the signing before the notary
Once all the documentation is ready and the buyer has their financing in place, it is time for the notary signing.
This is usually the most visible moment of the whole operation, even though it is really the result of all the work done beforehand.
The notary will check the documents, verify the identity of the parties and formalise the transfer of ownership through the public deed.
The better organised the transaction has been in the previous weeks, the easier this stage will be.
Calculate the selling costs correctly
Many people focus only on the money they will receive from the sale and forget that there are also specific costs linked to the transaction.
Depending on the case, there may be costs related to municipal tax, certain tax obligations or cancelling a previous mortgage registration.
That is why it is advisable to calculate these amounts in advance and know what net proceeds you are really going to receive after the sale.
If you want to go deeper into this point, you can read our guide on costs of selling a house, where we break down each of these items.
Hand over the property properly
Once the deed has been signed, one last important step remains: handing over the property.
The best approach is to provide the buyer with all keys, access remotes, available documentation and relevant information about utilities or property maintenance.
It is also advisable to record the final water, electricity and gas meter readings to avoid later disputes.
These are small details that help close the transaction in a much more professional way.
Mistakes you should avoid when selling a property
Most problems in a private property sale do not come from major conflicts.
They usually arise from small oversights: incomplete paperwork, poorly drafted contracts, unclear deadlines or financing issues.
Avoid the most common mistakes
That is why it is worth taking time to prepare each stage properly.
A well-organised sale reduces risk and gives both buyer and seller more peace of mind.
Avoiding the most common mistakes does not mean overcomplicating everything. It means having order, foresight and support in the sensitive parts of the transaction.
