Buying or selling a property is an exciting process, but it also involves a series of legal and administrative procedures that can be overwhelming if you are not prepared. Having all your documents ready from the start will save you time, avoid delays, and give the other party confidence.
In this article, you will find a practical checklist of the most important documents you will need, whether you are buying or selling a home.

Documents you need if you are buying a home  
Before signing, make sure you review and have the following documents in your possession:
1.    ID card or foreigner identification number (NIE)
To identify yourself throughout the process.
2.    Deposit agreement
This is the preliminary agreement setting out the basic terms and conditions of the sale.
3.    Simple note from the Land Registry
This confirms who the actual owner is and whether the property is free of encumbrances.
4.    Latest property tax and utility bills
To check that there are no outstanding debts.
5.    Property appraisal (if you need a mortgage)
Mandatory for the bank to grant the loan.
6.    Binding offer from the bank 
If you are financing the purchase, the bank will provide you with all the official documentation.

 Documents required if you are selling a property  
To ensure a smooth sale of your property, prepare the following documentation:
1.    ID card or foreign resident ID number
Mandatory personal identification.
2.    Deed
Document proving that you are the legal owner.
3.    Simple note from the Land Registry
Provides transparency to the buyer regarding any encumbrances or mortgages.
4.    Energy efficiency certificate
Required by law from the start of the sale.
5.    Latest property tax and utility bills (electricity, water, gas, community fees)
To prove that there are no outstanding debts.
