๐Ÿ“Š How This Works

We simulate two financial timelines based on different mortgage decisions. Life A uses your current path. Life B uses the optimized decision. The difference compounds over time โ€” showing not just the money gap but the life milestones affected.

๐Ÿ“‹ Assumptions & Data Sources

Investment returns assumed at 6% annually for cash not spent on housing. Home appreciation at 3.5% annually. Inflation at 3%. Educational use only โ€” not financial advice.

Prices and rates are widely reported. Whether a lender says yes is not. In the complete 2025 federal record, denial rates across the 100 largest FHA lenders ran from 1.8% to 78.7% — same programme, same year.

And it is not simply who applies where: standardizing on state, loan amount, income, debt-to-income and loan-to-value, applicant mix explains only a 2.7× range in expected outcomes.
