How to Get Pre-Approved for a Mortgage: A Complete Step-by-Step Guide

Q: Can I get pre-approved with bad credit?

Pre-approval is possible with scores as low as 580 (FHA with 3.5% down). With lower scores, expect higher rates and fewer lender options. Improving your score even 20-40 points before applying can save tens of thousands over the loan term.

Mortgage pre-approval is the gateway to serious homebuying. Without it, sellers won't take your offers seriously, you won't know your real budget, and you risk falling in love with homes you can't finance. This guide walks you through the complete process. See our companion guide on Pre-Approval vs Pre-Qualification to understand why pre-approval matters so much more than pre-qualification.

Step 1: Check and Improve Your Credit First

Pull your free credit reports from all three bureaus at annualcreditreport.com. Review for errors (up to 34% of reports contain them), high utilization, or negative items. Dispute errors immediately. Allow 60–90 days before applying so improvements can register. Even moving from 700 to 740 can meaningfully lower your rate — see our common mortgage mistakes guide for strategies.

Step 2: Calculate Your Real Budget

Use our Affordability Calculator to determine a realistic home price range. Use our Mortgage Calculator to see what different loan amounts cost monthly — including taxes, insurance, and PMI. Understanding how DTI works helps you know what to expect from lenders. Know your numbers before lenders run theirs.

Step 3: Research Your Loan Options

Conventional: 680+ credit, 5%+ down → read our FHA vs Conventional guide
FHA: 580–679 credit, limited down → same guide
VA: If eligible, always explore first → read our VA Loan guide
USDA: Eligible rural/suburban areas → read our USDA Loan guide
Jumbo: Loan above $766,550 → read our Jumbo Loan guide

Step 4: Gather Documents Before Applying

✅ Last 30 days of pay stubs (all employers)
✅ Last 2 years of W-2s from all employers
✅ Last 2 years of federal tax returns with all schedules
✅ Last 2–3 months of bank statements (all accounts)
✅ Government-issued photo ID
✅ Social Security number
✅ Residential addresses for past 2 years
✅ Employment history for past 2 years
✅ Gift letter if receiving down payment gift
✅ Divorce decree / child support documentation if applicable

Step 5: Apply With Multiple Lenders in the Same Week

Contact 3–5 lenders within the same 14-day window. Multiple mortgage inquiries in this period count as a single credit inquiry — no penalty for shopping. Include at least one bank, one credit union, and one online lender or broker. Request a Loan Estimate from each. Read our rate comparison guide to evaluate them properly.

Step 6: Compare Loan Estimates

Within 3 business days of each application, lenders must send a standardized Loan Estimate. Compare:

APR — the most useful single comparison number
Section A — origination fees where lenders differ most
Monthly payment including escrow
Rate lock period and extension costs
Points paid — calculate break-even using our points guide

Use our Loan Comparison tool to model different scenarios side by side.

Step 7: Choose a Lender and Lock Your Rate

Choose the lender with the best APR, fees, and service. Once you have an accepted purchase offer, lock your rate immediately. See our mortgage rates guide for why locking matters. Rate locks typically last 30–60 days — choose a period with adequate buffer for your closing timeline.
