Thinking about buying your first home? The excitement is real, but so are the details. Mortgages, credit scores, disclosures, and DTI ratios can feel like alphabet soup. Let’s break it down so you know what matters before you make your move.
Start with Your Financial Foundation
Lenders look at two things first: your income compared to your debt and your credit score.
Debt-to-Income Ratio (DTI):
- DTI = total monthly debt ÷ gross monthly income.
- Aim for 36% or lower.
- 28% or lower for housing expenses alone is considered strong.
- Conventional loans may approve up to 1%. FHA loans sometimes allow up to 57%.
- High DTI was the most common reason lenders denied mortgages in 2022.
Action steps:
- Pay down credit cards.
- Avoid new loans or credit cards before applying.
- Increase income where possible.
Student loans:
- Lenders count your minimum monthly payment, not your full balance.
- If you’re in an income-driven repayment plan, get documentation to prove your reduced monthly obligation. It can help you qualify.
Credit score:
- 620 = baseline for a conventional loan.
- 740+ = best rates.
- Check your credit at AnnualCreditReport.com.
- Fix errors quickly. Corrections can bump your score within 30 days.

Pre-Approval vs. Pre-Qualification
You’ve probably heard both terms. They aren’t the same.
- Pre-qualification: A quick, informal estimate based on self-reported info. Good for setting a budget.
- Pre-approval: Formal review of your income, assets, and debts. The lender confirms how much they are willing to lend. Sellers take this seriously.
Documents you’ll need:
- Pay stubs (last 30 days).
- W-2s and tax returns (2 years).
- Bank and retirement statements (60 days).
- Debt list (credit cards, loans, child support).
- Gift letters if you’re getting help with the down payment.
Timeline: Most letters last 60–90 days. Apply when you’re ready to shop seriously.
Pro tip: Get quotes from at least 3 lenders. Comparing saves thousands over the life of your loan. Multiple applications within 45 days usually count as one credit inquiry.
Know Your Loan Options
Not all mortgages work the same. Here’s a quick snapshot:
Feature | Conventional | FHA | VA (for veterans/military) |
|---|---|---|---|
Min credit score | 620 | 580 (3.5% down) / 500 (10% down) | No set minimum |
Min down payment | 3%–5% | 3.5% | Often $0 |
DTI tolerance | <1% | Up to 57% | Flexible |
Mortgage insurance | Required under 20% down; can cancel | Required regardless | None |
Appraisal | Standard, waivers possible | Strict HUD standards | VA-specific |
| Best if… | You have good credit and savings | You have lower credit or less saved | You qualify for VA benefits |
Read the Fine Print
Two documents will matter most:
- Loan Estimate (LE): Issued within 3 business days of applying. Breaks down rates, fees, and risks.
- Closing Disclosure (CD): Given at least 3 days before closing. Shows your final numbers.
Compare these carefully across lenders. Focus on:
- Total Loan Costs (Section D, page 2).
- Annual Percentage Rate (APR).
- Total Interest Percentage (TIP).
Rate locks: Protect your interest rate for 30–60 days. Extensions can be costly if your closing is delayed.
Lender credits: Can cover some closing costs, but expect a higher interest rate in return.
Avoid Mistakes After Pre-Approval
Yes, your loan can still be denied after pre-approval. Keep your finances stable until closing.
- Do not switch jobs or quit.
- Do not open new credit accounts or take on loans.
- Keep bank transactions clean. Document large deposits.
- Stay current on all bills.
- Watch for property issues. FHA appraisals are strict about safety and condition.
- Make sure the property is insurable. Coverage gaps can stop a loan.
Takeaway for First-Time Buyers
Buying a home isn’t only about finding the right house. It’s about proving to a lender that you are a safe bet. Your DTI, credit score, and stable financial behavior carry as much weight as your dream neighborhood.
Think of pre-approval as your green light to shop. Once you get it, protect it by keeping your finances steady.
Final Thought
Your first home purchase comes with steps you might not expect, but each step is designed to protect you and your lender. Start with strong credit and a solid DTI, get pre-approved with multiple lenders, compare loan terms carefully, and avoid financial missteps until the keys are in your hand.
