Ask what the lender has verified, what conditions remain and how long the letter is valid. Keep your home budget separate from the lender’s maximum.

Conditions still need to be met before final approval.
Understand the letter
Preapproval means a lender is tentatively willing to lend up to a stated amount, subject to conditions. It is not a guaranteed loan. Lenders use “prequalification” and “preapproval” differently, so ask what has actually been checked.
Ask for a document list
The lender decides what records it needs. Ask about income documents, bank statements, debt information and any extra records for self-employment or gift funds. Provide documents through the lender’s secure process.
Know what could change
Ask when the letter expires, what assumptions it uses and what could affect final approval or pricing. Tell the lender about planned changes to employment, borrowing or assets before relying on the letter.
Keep your own spending limit
The approved amount may exceed what feels comfortable. Use your household budget and the full housing payment to set your limit. Getting a letter does not commit you to that lender; compare official Loan Estimates before choosing.
Prepare complete documents
Collect the records the lender requests and include every page of statements. Keep a list of when each document was issued. The lender may ask for newer versions as the process moves forward.
Separate loan qualification from household comfort
A lender’s debt-to-income calculation is not a full household budget. Use your actual take-home pay to account for food, utilities, childcare, healthcare, savings and other needs. A payment that passes lender review can still be uncomfortable for you.
SEE THE NUMBERS
DTI example: use gross income
| Illustrative item | Monthly amount |
|---|---|
| Proposed housing payment | $2,100 |
| Car payment | $350 |
| Student-loan payment | $150 |
| Counted card minimum payments | $100 |
| Total counted debt payments | $2,700 |
| Gross income, before taxes | $7,500 |
| Example DTI | $2,700 ÷ $7,500 = 36% |
The lender decides which income and payments count under its program. A 36% example is not an approval threshold. Groceries and utilities still affect your household budget even if they are not counted as loan debts.

Questions to ask
Bring these to your lender, agent or housing counselor, as appropriate.
- What documents have you verified already?
- What conditions could change the approval or price?
- How do you count my variable or self-employed income?
Common questions
What documents should I gather?
Ask for the lender’s list. Common starting records include recent pay statements, W-2s, tax returns, bank statements, identity documents and records of down-payment funds. Your situation may require different or additional records.
What if I am self-employed?
Tell the lender early. It may need extra records to verify your income. Ask what documents and income calculation apply before setting a purchase budget.
Is DTI based on take-home pay?
DTI uses gross monthly income for the ratio. Use take-home pay separately when testing what your household can comfortably spend.
Your next steps
