3 official sources linked💡 Key takeaways
- Prequalification usually relies on information you report; preapproval relies on information the lender verifies.
- Neither is a guaranteed loan offer.
- A Loan Estimate is a standard form of terms and costs, not an approval.
- Get preapproved before house hunting and compare Loan Estimates from several lenders.
The three documents
| Document | What it is |
|---|---|
| Prequalification letter | How much a lender may lend, often based on information you report yourself (unverified). |
| Preapproval letter | A similar letter, but based on information the lender has verified. |
| Loan Estimate | A standardized form of the loan’s terms and costs, provided after you give the lender six pieces of information. It is not an approval or denial. |
CFPB notes that prequalification and preapproval letters give useful information about your likelihood of getting a loan but are not guaranteed loan offers.
How to use them
- Get a preapproval letter before you house-hunt so sellers see a verified figure.
- Request Loan Estimates from more than one lender and compare them line by line.
- Try the mortgage calculator and affordability calculator first to set a realistic budget.
What lenders ask for
- Recent pay stubs, tax returns and W-2s
- Bank statements
- Identification and Social Security number
- Permission to check your credit
Timeline
- Check your credit reports and budget.
- Get prequalified for an early idea, then preapproved.
- Shop for a home within the approved range.
- After choosing a home, apply and receive a Loan Estimate.
🔤 Key terms
