New to this? Quick definitions
- PITI —
- principal, interest, taxes, and insurance — the four pieces of your monthly mortgage payment, all added together.
- DTI (debt-to-income ratio) —
- what percent of your monthly income goes toward debt payments. Lenders use this to decide how much they'll let you borrow.
- Front-end vs. back-end DTI —
- front-end counts only your housing payment (PITI); back-end counts housing plus every other debt — car loans, student loans, credit cards.
- 28/36 rule —
- a lending guideline: housing costs shouldn't exceed 28% of your gross monthly income (front-end), and total debt payments shouldn't exceed 36% (back-end).
- Gross vs. net income —
- gross is your pay before taxes and deductions — the number lenders use. Net is what actually lands in your bank account, which is what you'll live on.
- PMI —
- private mortgage insurance, required when you put down less than 20%. It protects the lender, not you, and adds to your monthly payment until you build enough equity.

Where your money goes each month
Mistakes first-time buyers make
- Budgeting off gross income instead of what actually hits your bank account after taxes and deductions.
- Ignoring existing debt payments — car loans, student loans, credit cards — that count against your back-end DTI and shrink what you can borrow.
- Assuming a lender's maximum approval is what you should actually spend, rather than what you're comfortable paying every month.
- Forgetting that 10%-down loans carry PMI, which raises the monthly payment and the income you need to qualify.
Pro tips
- Treat the 28/36 rule as a ceiling, not a target — qualifying for a payment doesn't mean you should stretch to it.
- Pay down other debt before applying for a mortgage; lowering your DTI can qualify you for more house at the same income.
- Get pre-qualified early so you know your real number before you start house-hunting, not after you've fallen for a listing.
- Compare 20%-down and 10%-down scenarios side by side — the income required and monthly payment both shift with PMI.
