The First-Property Bundle

The step-by-step playbook, the six-calculator deal-analyzer toolkit, and the down-payment-assistance finder that turn these numbers into an actual plan — scripts, a real duplex case study, and the worksheets I wish I’d had when I started.

Pay what you want. Name your price — and if money’s tight, take it for less. If you can pay the suggested amount, it helps me keep the tools free.
