TurboHELOC
A high-converting fintech landing page for a HELOC lender. Built with Astro + React islands architecture for optimal performance. Features an interactive equity calculator with real-time donut chart visualization, 4-step pre-qualification form, comparison tables, FAQ accordion, and blog CTA section. Fully responsive with pixel-perfect Figma-to-code execution.
01
The challenge
The client needed a high-converting landing page that could explain a complex financial product (HELOC) simply, build trust with borrowers, and capture pre-qualification leads, all while meeting strict financial compliance requirements.
02
The solution
Designed and built a 12-section single-page experience with interactive tools that let users self-qualify. The calculator gives instant borrowing estimates, reducing friction. Astro's islands architecture ensures sub-second load times while keeping React interactivity where it matters.
03
How it was built
- 01 Astro + React islands for optimal performance/interactivity balance
- 02 Custom slider and donut chart components for the HELOC calculator
- 03 Mobile-first responsive design with Tailwind CSS
- 04 Structured data (FinancialProduct JSON-LD) for SEO
04
Technical deep-dive
Built on Astro with React islands: static sections (Hero, How It Works, Footer) ship zero JS, while interactive components (Calculator, Comparison Table, FAQ, Use Cases carousel) hydrate on visibility via client:visible. The HELOC calculator computes borrowing power in real-time using 80% LTV with a $750K cap, rendered as a custom SVG donut chart. The pre-qualification form uses client:load for instant availability when triggered from any CTA button.
05
Growth and SEO
Targeted high-intent keywords like "HELOC calculator", "home equity line of credit rates", and "HELOC pre-qualification". Implemented FinancialProduct structured data for rich search results. The comparison table and FAQ sections capture long-tail queries around HELOC vs mortgage differences and eligibility requirements.
