Step-by-step client guide
Pre-approval with a heavy car loan
Vehicle loans are quietly the most common reason borrowers fail the stress test. The math is brutal: every $400/month of debt cuts your max mortgage by about $70,000.
Who this guide is for
Anyone carrying a vehicle loan or lease over $500/month, anyone shopping for a car within 6 months of applying for a mortgage.
Why this is harder than a standard file
A $800/month car payment can reduce maximum mortgage by $100,000+ depending on rate and amortization.

If you're within 12 months of a mortgage, lease or finance with the smallest possible monthly payment — or wait.

0 of 3 documents gatheredMistakes we see clients make in this scenario
- ·Buying a car between pre-approval and closing. Lenders re-pull credit before funding and a new loan can collapse the deal.
- ·Paying down the principal but not the payment. The TDS calculation uses the monthly amount, not the balance.
Red flags that will sink the file
- Recent car loan with high payment relative to income.
- Multiple vehicle loans in the household.
What this realistically costs you
- A $700/month car payment costs roughly $125,000 of mortgage qualification at current rates. That's often the difference between qualifying and not.
How the underwriter actually reads this
Underwriters use the full monthly payment in TDS — there is no offset for asset value. Paying down the principal does not reduce the payment; refinancing the loan to a longer term can.
What moves this file up
- Pay out the car loan entirely if possible before applying
- Refinance the loan to a longer term if payout isn't feasible
- Wait until under 10 payments remaining (some lenders exclude near-term loans)
Questions clients ask us
Usually yes, if you can do it without dropping below your minimum down payment. The qualification lift typically outweighs the cash cost.
Lease payments count the same as loan payments in TDS. Buyouts at end-of-lease don't help unless the buyout actually happens before application.
