That $20k car loan could cost you $50,000 when you go to buy a house.
Not in interest. In borrowing power.
Lenders don’t look at what you owe on the car. They look at the monthly repayment. Every $100 a month in repayments cuts roughly $12,000 from what you can borrow for a home.
📉 $10k car loan: about $25k less borrowing power
📉 $20k car loan: about $50k less
📉 $30k car loan: about $76k less
📉 $45k car loan: about $114k less
And the twist: paying the same $20k car off faster, over 3 years instead of 5, makes the hit bigger, at about $77k. A higher monthly repayment means a bigger hit, even though you’re clearing the debt sooner.
None of this means don’t buy the car. It means get the order right. If a home purchase is on the cards in the next year, run the numbers before you sign at the dealership, not after.
