No home goes live without FISBU's verification.
We confirm the information needed to guarantee real, safe listings.
Ownership
We confirm that you own the property and have the right to sell it.
Property documents
We validate the caderneta predial with the tax authority before the listing goes live.

More safety for you and a more efficient process.
Identity
We verify buyers' identity before they contact you.
Financial capacity (optional)
Some sellers only want to be contacted by financially verified profiles. By validating your financial capacity, you unlock these homes.
The deal in the chat
Everything is recorded in the same place.
From the first contact, follow messages, visits and offers on the platform, with every step recorded.

- Book and confirm visits to the home.
- Send and answer offers.

Still have questions? Start with these.
Yes. Listing, selling and buying are free, including the promissory contract (CPCV).
No. FISBU holds a real estate brokerage licence (AMI no. 27887), but it doesn't work like a traditional agency: it doesn't take on listings, doesn't represent sellers or buyers and charges no commission.
It connects sellers and buyers directly: you get the tools, the support and buyers with verified identities to sell your home fully in control.
Selling on your own doesn't mean being alone.
Whenever you need it, you have support throughout the process to answer questions and help at each stage of the sale.
Because selling a home is important enough already.
It makes no sense to lose thousands of euros in commission, take constant calls from agents and still deal with dozens of curious visitors.
On FISBU, you talk directly to qualified buyers and stay in control of the sale from start to finish.
Have a home to sell?
No commission. No exclusivity. At your own pace.
