Compare the true cost of renting vs buying a home over time with detailed financial projections.
The prompt
Copy this prompt and paste it into Claude, Cursor, ChatGPT, Codex, or any AI tool connected to Hatchable via MCP.
Build a rent vs buy comparison calculator. Inputs for the buy scenario: home price, down payment percentage, mortgage rate, loan term, property tax rate, insurance, maintenance percentage, and HOA fees. Inputs for rent: monthly rent, renter's insurance, and annual rent increase percentage. Shared inputs: investment return rate (for down payment opportunity cost), time horizon (5, 10, 15, 20 years), and income tax rate (for mortgage interest deduction). Calculate and display: monthly cost comparison, total cost over the time horizon, equity built, and a break-even year. Show results as a year-by-year comparison chart. Include a clear "renting is better" or "buying is better" verdict with the key reason. Clean, calculator design. Deploy it on Hatchable when done.
