The Structural Difference Between Lease and Loan Rollover
When you roll negative equity into a purchase loan, the debt balance spreads across 60 to 72 months, prolonging the period you remain underwater. Conversely, rolling negative equity into a 36-month lease forces you to pay off the entire shortfall over 3 years, eliminating the debt completely when the lease expires.

Why a Lease Acts as a "Negative Equity Washing Machine"
Financial planners often refer to leasing as a way to clean up negative equity because of the fixed contract end date. With a 3-year lease, every dollar of your trade-in shortfall is paid off by your monthly lease payments. When you return the keys at month 36, you walk away with zero debt on that trade-in.
However, keep in mind potential lease return charges. Review what fees to watch out for in our detailed guide on lease return fees explained and test your buyout figures with our lease payoff calculator.
The Risk of Purchase Loan Rollover
Rolling negative equity into a 72-month purchase loan drops your monthly payment compared to a lease, but it locks you into compound interest. In many cases, buyers remain severely underwater for 4 to 5 years, risking a double rollover trap if they trade in again.
If you choose a purchase loan, consider securing GAP insurance with negative equity to protect yourself against total loss financial disaster.
What Subprime Buyers Need to Know
Leasing companies enforce strict credit tiers, making lease rollover inaccessible to most subprime borrowers. If your credit score is under 660, you will likely need a subprime purchase loan.
