Audited planning profile
This conservative annual profile applies a 1.2× editable baseline across 12 model periods to the mortgage debt breakeven model.
Compare the break-even period with the time you realistically expect to keep or use the option. Use this profile when protecting downside matters more than optimizing the headline result. Include annual renewals, maintenance, taxes and seasonal variation.
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.
