## About the MLS for Spain

### What is an MLS?

An MLS (Multiple Listing Service) is a shared database where estate agencies publish the properties they are instructed to sell, so that other professional agents can sell them too and share the commission. In the United States almost every sale goes through one. Spain never had a single national MLS: agencies relied on portals, local exchanges and informal sharing agreements.

### Is there an MLS in Spain?

Yes. The NLS (National Listing Service) is the MLS for Spain. It brings member agencies' properties together in one place, each verified to the agent authorised to sell it, with the tools agents need to collaborate across agencies, match buyers and manage every sale through to completion.

### What The NLS includes

- A shared database of properties for sale, verified to the authorised listing agent
- AI property search in plain English or Spanish
- Buyer Wants: live buyer demand matched against inventory
- Recently sold and agreed prices
- Real estate CRM, client showcases and open houses
- 49 real estate contracts with built-in e-signatures and deal management
- XML import and export with portals and CRMs
- A public directory of agents and agencies

### For buyers

Buyers search one verified listing instead of seeing the same home repeated across portals at different prices. Every listing links to the agent authorised to sell it.

### For agents and brokerages

Agencies share inventory with the whole network, find buyers for their listings and listings for their buyers, and run clients, contracts, signatures and deals in one platform.
