Multi-DEV the multiple listing service for the real estate developers within the Costa Vallarta region. It was created in 2001 as an additional MLS service for real estate developments. Only properties that exist and can transfer titles are allowed in Multi-List Vallarta, which made it difficult for developments trying to pre-sell the products. Multi-DEV (MDV) was created specifically for new developments in the region and it now works seamlessly with Multi-List Vallarta, available for all members of MLV to access and available for the public to view at VallartaRealEstateGuide.com

The properties listed in Multi-DEV Vallarta are new homes or condominiums within developments at various stages of completion.
