Client Overview
Andes Mortgage is a U.S.-based lender offering personalized, transparent home financing. Operating across several states with a multilingual team, they help individuals find the best home loan options tailored to their financial needs. To provide a better user experience, they wanted to offer a seamless digital experience for their clients, providing real-time mortgage rates and advanced calculators to help users make informed decisions.
The Challenge
The mortgage industry is highly competitive, especially when it comes to attracting attention online. A well-designed website helps not only generate leads but also speed up sales cycles, stay available 24/7, and build trust with potential clients. Andes Mortgage needed a solution that would provide customers with accurate, real-time mortgage rates and offer tools such as mortgage calculators to simplify complex financial decisions. The goal was to enable more self-service and reduce the number of clicks needed to get results. Their existing website lacked these interactive, data-driven features, and they needed a way to deliver this functionality efficiently without overhauling their entire site and keeping it on budget.
Our Solution
The Southwave team was tasked with helping to improve Andes Mortgage's digital presence by building custom Elementor widgets and integrating them into their WordPress-based website. These widgets integrate with Zillow API to provide real-time mortgage data and custom mortgage calculators to give users a highly interactive experience.
Key Deliverables:- Custom Elementor Widgets We developed several Elementor widgets tailored to meet the needs of the mortgage industry. These widgets allow Andes Mortgage to display real-time mortgage rates and calculators directly on their site, offering an engaging, intuitive user interface for potential homebuyers and refinancing clients. Each widget is customizable and can be placed on any page built with Elementor, providing maximum flexibility of use.
- Zillow API Integration Leveraging the Zillow API , we enabled real-time data retrieval for mortgage rates and market insights, ensuring users have access to the most up-to-date information. This integration was crucial in building trust with clients who rely on accurate data when making significant financial decisions.
- Reusable Plugins We built the widgets and calculators as separate plugins, stored for future reuse. This modular approach means Andes Mortgage can expand their functionality in the future without needing to rebuild or redevelop from scratch, saving them both time and resources.
- Mortgage Calculators We developed a suite of custom calculators, including a mortgage calculator, FHA loan calculator, affordability calculator, and refinance calculator. These tools provide clients with instant insights into their mortgage options, making the loan process more transparent and user-friendly.

Technologies Used
- Technologies: WordPress + Elementor, Vue.js 3 (SCSS, Vite);
- Programming Languages: JavaScript, PHP;
- API Integration: Zillow API;
- Hosting & Version Control: GitLab for plugin storage and versioning.
In the mortgage industry, trust and transparency are vital. Custom solutions we provide not only improve the functionality of websites like Andes Mortgage's but also enhance their ability to serve their clients more effectively. By offering real-time mortgage rates and financial calculators, Andes Mortgage can now empower users to make more informed decisions faster.
Summary
This project wasn't about a complete redesign. It was about adding what really mattered. With custom-built Elementor widgets, real-time data via Zillow API, and calculators that actually help, Andes Mortgage now gives its clients the tools to make smarter decisions on their own terms. No heavy rebuild, no wasted effort, just the right solutions, built to grow with their business. If your website is missing the tools your clients actually need, let's discuss how we can help!
