# Buyer Underwriting and Finance (/docs/playbooks/buyer/underwriting-and-finance)



Direct Answer [#direct-answer]

Underwriting must include total monthly carry, board/liquidity constraints, taxes, and transaction fees. Treat financing as a risk-control system, not just a rate-shopping step.

Key Workstreams [#key-workstreams]

* Model all-in monthly costs: principal, interest, taxes, maintenance/common charges, insurance, reserves.
* Validate board-style liquidity and DTI constraints before offers.
* Include mansion tax and closing-cost tiers in EV analysis.
* Pre-negotiate lender timeline and contingency windows.
