A 2025 Guide from InterWest Mortgage
When preparing to buy a home, many borrowers wonder, “What do mortgage lenders look for?” Whether you’re a first-time buyer, refinancing your current home, or investing in real estate, knowing what lenders evaluate can make your journey much smoother.
At InterWest Mortgage, we believe in transparency, education, and helping you feel confident throughout your home loan process. With nearly 440 five-star Google reviews, recognition as Idaho’s Best of 2025, and Best of Greater Idaho Falls 2025, we’re proud to offer personalized service and competitive mortgage rates in all 50 states — especially throughout Idaho Falls, Rexburg, Rigby, Shelley, Firth, Pocatello, and Iona, Idaho.
Let’s explore precisely what lenders review during your mortgage application and how to set yourself up for success.
1. Your Credit Score and Credit History
Your credit score is one of the most significant factors lenders use to determine eligibility. It helps them measure how reliably you’ve handled past debt.
- Conventional Loans: Minimum credit score of 620+
- FHA Loans: Accepts scores as low as 580
- VA and USDA Loans: More flexibility for qualifying borrowers

Lenders also review your credit report for:
- Late or missed payments
- Loan defaults or collections
- Total credit utilization
- Recent credit inquiries
Pro Tip: Request a free copy of your credit report and correct any errors before applying. Even minor adjustments can improve your interest rate and loan options.
2. Your Debt-to-Income Ratio (DTI)
Your debt-to-income ratio (DTI) measures your monthly debt compared to your gross monthly income. It helps lenders assess whether you can comfortably afford a new mortgage payment.
Most lenders prefer a DTI below 43%, though specific programs may allow higher ratios with compensating factors.
Formula:
Monthly Debts ÷ Gross Monthly Income = DTI
Example: If your debts total $2,000 per month and your income is $6,000, your DTI is 33%.
Lower DTI = less financial risk = stronger loan application.
3. Employment and Income Stability
Mortgage lenders value steady employment and reliable income. They’ll usually review your work history for the past two years, checking:
- Pay stubs
- W-2s or 1099s
- Tax returns (for self-employed borrowers)
If you’re self-employed, consistent income documentation is key. Our InterWest Mortgage team can help you gather and present your financials clearly to improve your chances of loan approval.
4. Down Payment and Loan-to-Value Ratio (LTV)
Your down payment directly affects your loan terms and approval odds.
- Conventional Loans: 3–5% minimum down
- FHA Loans: 3.5% minimum down
- VA Loans: Often 0% down
- USDA Loans: Often 0% down for rural homebuyers
Your loan-to-value ratio (LTV) is the amount borrowed versus the property’s value. A lower LTV typically earns better interest rates and can eliminate the need for private mortgage insurance (PMI).
Pro Tip: A 20% down payment is ideal for avoiding PMI and securing the best possible rates.
5. Savings and Assets
Beyond your income, lenders also review your cash reserves and other assets. This shows that you have funds for emergencies, closing costs, or unexpected repairs.
Examples include:
- Checking or savings accounts
- Retirement plans (401k, IRA)
- Stocks or mutual funds
- Cash gifts (adequately documented)
Having even two to three months of mortgage payments in savings can make a strong impression on underwriters.
6. The Property Itself
The home you choose is part of the lender’s risk assessment. A licensed appraiser will verify that the property’s market value supports the loan amount.
Lenders will also ensure the home meets the minimum condition standards required by the loan type. For example, FHA and USDA loans require specific property safety and habitability checks.
Working with a local real estate agent familiar with these guidelines can make your process faster and smoother.
7. Loan Type and Program Selection
The type of mortgage you apply for shapes your qualification path. InterWest Mortgage offers a range of programs to meet your goals:
- Conventional Loans: Great for solid credit and flexible terms
- FHA Loans: Perfect for first-time homebuyers or those rebuilding credit
- VA Loans: Exclusive to veterans and service members
- USDA Loans (Rural Development): Ideal for low- to moderate-income buyers in rural areas
- Idaho Housing and Finance Loans: Designed for Idaho residents needing down payment help
👉 Visit our Refinancing page if you already own a home and want to lower your rate or access equity.
Our experienced loan officers will help you find the best-fit program based on your credit, income, and long-term financial goals.
8. Documentation and Transparency
A well-organized loan file is key to a smooth approval process. Lenders will ask for:
- Government-issued ID
- Pay stubs and tax returns
- Bank statements
- Proof of assets and debts
- Purchase agreement (for new homes)
At InterWest Mortgage, we simplify this step with our secure online application portal, allowing you to upload documents, sign forms, and track progress from any device.
