Summary answer: Most lenders want your total debt-to-income (DTI) ratio at or below 43%–45% to qualify for a conventional loan in Arlington, though some go higher with strong compensating factors like a high credit score or large reserves. VA loans can go higher still, often into the 50s, using a residual-income method rather than a hard DTI cap. Given Arlington's price point, staying well under that ceiling — closer to 36% — is what actually gives you competitive purchasing power.
I'm Johnny with JQ Real Estate. Let me break down what DTI actually means for your Arlington search.
Front-end vs. back-end DTI
| DTI Type | What It Measures | Typical Max |
|---|---|---|
| Front-end | Housing payment only (mortgage, taxes, insurance, HOA) ÷ gross income | 28%–31% |
| Back-end | All debt (housing + car, credit cards, student loans, etc.) ÷ gross income | 43%–45% (conventional); higher for VA |
Why Arlington makes back-end DTI the real constraint
In a lot of markets, front-end DTI is the binding limit — buyers simply can't afford a big enough mortgage payment to hit the back-end cap. In Arlington, it often flips: because condo HOA fees frequently run $300–$600+/month and get counted as part of your housing payment, buyers hit their front-end limit faster than expected, even with modest other debt. This is worth knowing before you fall in love with a building that has high monthly fees — the fee itself can be the thing that caps your qualifying price, not the mortgage.
What counts against you
- Car payments
- Minimum credit card payments (even if you pay in full monthly, lenders often use the statement minimum)
- Student loans (see how these get calculated specifically)
- Any other reported monthly debt obligation, including co-signed loans
What doesn't count
- Utilities, phone bills, subscriptions, groceries
- Debt that will be paid off before closing (if documented)
- Income-based child support or alimony you're receiving (this counts as income, not debt, on the receiving side)
How to improve your DTI before you shop
- Pay off or pay down a car loan or credit card — even eliminating one smaller debt can meaningfully shift your qualifying amount
- Avoid financing new purchases before closing — a new car loan mid-process can derail an approval
- Consider a co-borrower — combines both income and debt, which can help or hurt depending on the other person's profile
- Target lower-HOA buildings if you're condo shopping — this directly protects your front-end ratio in Arlington specifically
