Hi, I need help building a real estate deal analyzer SaaS app in Bubble.io with an OpenAI API integration.

App name:
AI Sonara

Inputs (user enters these values):
1. Purchase Price ($)
2. Repair Costs ($)
3. After Repair Value (ARV) ($)

5. Down Payment %
6. Loan Interest Rate %
7. Loan Term (Years)
8. Closing Costs ($)
9. HOA Fees ($/month)

12. Property Taxes ($/year or %)
13. Insurance ($/year or %)

Outputs (from AI analysis):
• Monthly cash flow

• Notes on deal strength/weakness (pros & cons)

Requirements:
• Build a clean landing page with subscription pricing tiers:
• Starter Plan: $19/month
• Pro Plan: $49/month (set up but can be hidden for now)
• Integrate Stripe (or another payment gateway) for subscriptions.
• Ensure all inputs are connected properly to the AI so analysis is accurate.
• Final product should be professional, mobile-friendly, and simple for investors to use.
