Real experiences
Real cases from buyers and sellers
“We sold our flat without paying commission to third parties and handled almost everything online. What we valued most was not having to coordinate calls and documents across different channels.”

“We used Firma Vivienda with the launch promotion and the savings versus a traditional estate agency were huge. The platform let us stay in control without feeling left alone.”

Are you buying or selling a property and need an earnest money contract?
Most people encounter unclear templates, doubts about deadlines and penalties, and disorganised documentation and follow-up procedures.
The usual approach (and what tends to go wrong)
Incomplete or outdated online templates.
Contracts that don't properly reflect the transaction (earnest money, deadlines, parties, annexes…).
Scattered documents (IDs, Nota Simple, receipts).
No guidance for the later stages (notary, utilities, follow-up).

Firma Vivienda helps you complete the entire property sale: lawyer-reviewed contract, electronic signature, earnest money transfer, appraisers, mortgages, notaries and utilities. The seller pays nothing.
Guided generation of the earnest money contract.
Access for buyer and seller.
Organised and accessible documentation.
Follow-up and subsequent procedures from the dashboard.

Frequently asked questions
We answer the most common questions before creating an online earnest money contract.
Is an online earnest money contract legal?
Yes. It is a private agreement between buyer and seller. The important thing is that the document correctly includes the data, the price, the earnest money amount, the deadlines and the agreed conditions. Firma Vivienda guides you to generate the contract with that information.
Can I preview the contract before paying?
Yes. You can review a preview and send it to the other party for review. After payment, the full PDF download is unlocked for both buyer and seller.
Who pays for the service?
The buyer makes the payment. After payment, the contract download is unlocked and the invoice is automatically generated, which the buyer can view/download from their dashboard.
What documentation do I need?
Usually: IDs of the parties and the Nota Simple of the property. The platform will tell you what to upload and when, and will keep it organised within the file.
Is Firma Vivienda an estate agency?
No. Firma Vivienda is a digital platform for generating and organising property sale documentation and helping with subsequent procedures (such as utilities). We don't intervene in negotiations and don't charge estate agent commission.
