Real estate broker ZipRealty and banking giant Citigroup (C) formed a strategic marketing agreement to provide mortgage services to the former’s homebuyers.

Citigroup will provide ZipRealty with a multilevel mortgage services platform that will allow prospective homebuyers access to services such as pre-qualification, application tools and home financing assistance.

"The relationship with Citi allows ZipRealty to present an array of mortgage options to meet the individual needs of our homebuyers," ZipRealty Chief Executive Lanny Baker said.

Prospective homebuyers are matched to a customer service representative to guide them through the entire application process. Citi has a dedicated call center, and also has loan professionals in every ZipRealty market. This model, and its ease of execution, ZipRealty said, allows Citi to offer homebuyers an on-time closing guarantee.

This is the second mortgage alliance ZipRealty has announced in the past 30 days forming a dual platform to service its homebuyer's needs.
