What Does Your DTI Mean?
Front-End DTI โ just your housing payment divided by gross income. Most lenders want this below 28โ31%.
Back-End DTI โ ALL monthly debts (housing + car + student loans + cards) divided by income. This is what lenders focus on most.
Every $200/month in debt reduces your buying power by roughly $40,000. Paying off a car loan before buying can make a significant difference.
VA loans have a 41% guideline but lenders regularly approve above that with strong compensating factors โ residual income plays a bigger role than DTI on VA loans.
