DTI compares:
Monthly debt payments (minimum payments that show on credit + your new housing payment)
÷ Gross monthly income (before taxes)
Most lenders look at a back-end DTI (all debts + housing). Some also look at a front-end DTI (housing only).
Use this:
DTI % = (Total monthly debt payments ÷ Gross monthly income) × 100
What counts as "monthly debt" in the lender's eyes?
Lenders use the minimum required payment, not what you choose to pay monthly.
Minimum credit card payments
Auto loan / lease payments
Student loan payments (rule depends on loan type and repayment plan)
Personal loans
Child support / alimony (if applicable)
Any other mortgage payments
New housing payment (principal + interest + taxes + insurance + HOA)
In Broward, Miami-Dade, and Palm Beach, buyers often qualify on principal and interest, then get squeezed by the "extras." For a deeper breakdown, review how the true cost of owning a home in South Florida goes far beyond the mortgage payment.
And because insurance can swing your payment by hundreds each month, it helps to understand what Florida buyers should realistically budget for home insurance in 2026.
Below are simplified examples to show how DTI works. These examples assume typical underwriting guidelines and do not replace a personalized pre-approval.
Gross monthly income: $7,000 ($84,000/year)
Monthly debts:
Auto: $450
Credit cards: $120
Student loans: $200
Estimated housing payment (PITI + HOA): $2,600
Total monthly debts: $450 + $120 + $200 + $2,600 = $3,370
DTI: $3,370 ÷ $7,000 = 48.1%
What this means: This buyer is close to the edge. Paying down a car loan, lowering card balances, or choosing a lower HOA/insurance property can make the file feel much safer.
Gross monthly income: $9,500 ($114,000/year)
Monthly debts:
Auto: $525
Credit cards: $90
No student loans
Estimated housing payment (PITI + HOA): $3,300
Total monthly debts: $525 + $90 + $3,300 = $3,915
DTI: $3,915 ÷ $9,500 = 41.2%
What this means: This buyer has more breathing room, but Miami-Dade condos and HOA dues can change the outcome quickly. If you're buying a condo, review what's considered a reasonable HOA fee in Florida and which red flags to avoid in 2026.
Gross monthly income: $6,200 ($74,400/year)
Monthly debts:
Credit cards: $80
Student loans: $150
Estimated housing payment (PITI + HOA): $2,250
Total monthly debts: $80 + $150 + $2,250 = $2,480
DTI: $2,480 ÷ $6,200 = 40.0%
What this means: This buyer is in a healthier range. Keeping debts stable and documenting funds cleanly can speed up approval.
Pay off or refinance high monthly payments (auto loan is the most common DTI killer).
Reduce revolving utilization (it can help credit and sometimes lowers the minimum payment).
Shop smarter on total payment (insurance + taxes + HOA), not just price.
It also helps to understand how much cash Florida buyers realistically need to close and maintain healthy reserves in 2026.
