Nikolai “Nick” Castillo, Regional Manager

Guarantee Rate Affinity NMLS # 36862

 

A U.S. Army combat veteran, Nick Castillo brings the same dedication, discipline and problem-solving skills to his career that he did in service to his country. “After my years in military service, I wanted a career where I could continue helping people,” he explains. “I’ve always been an acts-of-service guy, and the lending industry allows me to support my community by guiding people into achieving the dream of homeownership.”

In the industry for 24 years, Castillo is a regional manager with Guarantee Rate Affinity. Serving the entire state of Arizona, he leads a team specializing in first-time homebuyers, the luxury market and VA loans. Fluent in both English and Spanish, he excels in connecting with a diverse clientele, ensuring clear communication and personalized service. “Setting proper expectations from the start and managing the process every step of the way provides a positive and successful experience,” he says.

A member of the National Association of Hispanic Real Estate Professionals, Castillo is an avid supporter and representative of the Veterans Association of Real Estate Professionals. Recognized for his strategic leadership and deep market expertise, he believes his commitment to excellence, integrity and customer satisfaction has made him a trusted leader in the industry. “Along with my military career, I also trained as a firefighter,” he shares. “Both taught me the discipline to never give up and continue to give the best service with integrity and high level of communication and trust.”

With three of his older kids having graduated from college this past year, Castillo moved his family into their new home. When he’s not busy working or attending his kids’ sporting activities, he enjoys golfing, hiking and playing pickleball.
