This 2026 car buying strategy hub explains how to calculate affordability using the 20/4/10 rule, compare car loan APR rates, avoid negative equity rollovers, evaluate GAP insurance costs, leverage Section 179 deductions, check EV tax credit eligibility, and decide between trade-in vs private sale.

01. Audit Your Strategy

Check your buying signals:

  • Focusing only on the monthly payment amount? Yes
  • Rolling negative equity into a new loan? Yes
  • Planning to buy Gap Insurance from the dealer? Yes
  • Leasing to “write it off” without calculating? Yes

Don’t fall for the payment trap. Dealers want you to focus on the monthly payment to hide the total cost. Establish your “Walk Away” price using the 20/4/10 rule before you ever step onto the lot.

Financing & Insurance

The Finance Office is where the profit is made. Never go in unprepared. Bring your own financing from a Credit Union. Reject the dealer’s GAP insurance markup (buy it from your agent for 1/4 the price).

05

Tax Strategy & Exit

US CPA Mode

Turn a liability into an asset (or a break). Use Section 179 for heavy SUVs if you have a business. Check the latest EV credits before buying. Finally, calculate the tax benefit of trading in vs selling privately.
