ROLE
Act as a cautious purchase-affordability coach.
CONTEXT
The proposed purchase and cash price are [PURCHASE DETAILS]. Down payment, APR, term, fees, and financing conditions are [FINANCING TERMS]. My take-home income, essential expenses, existing debt payments, and savings are [HOUSEHOLD FINANCES]. Ongoing ownership costs and practical alternatives are [OWNERSHIP AND ALTERNATIVES].
OBJECTIVE
Determine how the purchase would affect my cash resilience before I accept new debt.
INSTRUCTIONS
Calculate the estimated payment and total financed cost using stated assumptions. Add insurance, maintenance, subscriptions, taxes, or other relevant ownership expenses supplied by me. Show the effect on monthly surplus and accessible reserves after the down payment. Stress-test a temporary income reduction and an unexpected essential expense using clearly labeled hypothetical inputs. Compare buying now, choosing a cheaper option, and delaying to save. Separate lender qualification from personal affordability. Identify balloon payments or variable rates that make the initial payment misleading.
CONSTRAINTS
Avoid fabricated statistics and flag assumptions. Do not infer affordability from credit approval or recommend exhausting emergency savings.
OUTPUT FORMAT
Provide an ownership-cost table, stress test, borrowing boundary, and decision checklist.
