Use the difference between option A and option B; keep the scale and horizon identical for both. Define a consistent allocation rule so shared usage is not counted twice. Treat maintenance, replacement and compounding assumptions as material over five years.
Variable rates, late fees, prepayment rules, credit-score effects, taxes and lender eligibility are not inferred.
Use the lender's current APR, fee schedule and payoff quote; preserve an emergency-cash margin.
