30-year wealth projection

We don't just compare monthly payments. We track equity, home appreciation, opportunity cost on the down payment, and rent growth — then chart the wealth each path produces.

Assumptions and limits. This is a deterministic projection, not a guarantee. Real outcomes depend on selling costs (5–6% of home value), capital gains tax on the investment account, refinancing, life events, and market timing. Use this to understand directionally which path builds more wealth under your specific assumptions — then sanity-check with a CPA before making a 30-year commitment.
