Mortgage Preapproval Checklist for California Home Buyers

1. Know what a preapproval letter means

The CFPB defines a preapproval letter as a statement that a lender is tentatively willing to lend up to a certain amount. It can help show a seller that financing appears plausible, but it is not a guaranteed loan offer. Final approval depends on complete underwriting, updated borrower information, the property, and satisfaction of all conditions.

“Prequalification” and “preapproval” are not standardized labels used identically by every lender. Ask what was actually reviewed:

• Was credit checked?
• Were income and assets documented or only stated?
• Was the file run through an automated underwriting system?
• Which debts and housing costs were included?
• What assumptions could materially change the result?

The depth of review matters more than the label on the letter.

2. Choose timing that matches your shopping plan

Many buyers wait until they are preparing to shop seriously because lenders generally check credit and preapproval letters can expire. The CFPB notes that a letter is often valid for roughly 30 to 60 days, although the actual period is lender-specific. Starting earlier can still be valuable when you need time to correct a credit-report error, document an unusual income source, or build additional savings.

If your timeline is uncertain, begin with a planning conversation and ask when a full credit-based preapproval would be most useful. A request for general rate information alone does not authorize a credit pull; the CFPB explains that lenders generally need a permissible purpose such as a credit application.

3. Organize income and employment records

The objective is to show the source, amount, history, and expected continuity of income used to qualify. Depending on your situation, the requested records may include:

Do not assume gross business revenue, a current bank balance, or the amount deposited into your personal account is the same as qualifying income. If you own a business, read the self-employed mortgage guide before collecting records.

4. Organize assets and the source of funds

List the accounts and other acceptable sources you expect to use for the down payment, closing costs, and reserves. Have complete statements available for the period your lender requests, including every page even when a page appears blank.

Flag these situations before moving money:

• a gift from a relative or another eligible donor;
• sale of an asset;
• funds arriving from another account;
• a large or unusual deposit;
• retirement assets or investment accounts;
• business funds; or
• down-payment assistance.

A clean paper trail is easier to review than unexplained transfers made shortly before closing. Ask before consolidating accounts or accepting funds so you know what documentation may be needed.

5. Review monthly obligations and credit reports

Create a list of recurring obligations, including housing, auto, student, installment, credit-card, support, and other debts. If a debt is paid by someone else, disputed, deferred, co-signed, or tied to a business, flag it rather than assuming it will be excluded.

Review your credit reports for accounts you do not recognize, incorrect balances, duplicated debts, or personal-information errors. The CFPB’s credit preparation guidance explains what lenders review and how to address errors. Do not pay off or close accounts solely to “help” a mortgage application without first understanding how the change could affect available funds and credit.

6. Set realistic purchase and payment assumptions

A preapproval amount is meaningful only when its assumptions resemble the homes you may actually buy. Share a realistic range for:

• purchase price and down payment;
• property location, because taxes and insurance vary;
• property type and anticipated occupancy;
• HOA dues, if you are considering a condominium or planned community;
• seller credits or assistance funds, if part of the plan; and
• your desired cash reserves after closing.

Test payment scenarios with the mortgage calculator, then add estimated taxes, insurance, mortgage insurance, HOA dues, and other property-specific costs. The first-time home buyer guide explains how these pieces fit into the full purchase process.

7. Ask questions that expose the assumptions

Before using the letter, ask:

1. Which loan type, down payment, rate, and property costs were assumed?
2. Is the rate locked? If not, how could a different rate change the payment or approval amount?
3. Which income and assets have been documented, and what is still outstanding?
4. What conditions could reduce the approved amount or prevent final approval?
5. How long is the letter valid, and what must be refreshed?
6. Can the letter be tailored to a specific offer without displaying my full maximum amount?
7. What property types or conditions should I discuss before making an offer?

Preapproval is not the moment to choose a lender permanently. The CFPB recommends waiting until you have made an offer and received official Loan Estimates before making the final loan comparison.

8. Protect the file between preapproval and closing

Lenders may re-check credit and verify employment or assets later. Until the loan closes:

• avoid applying for new credit unless you have discussed it first;
• do not co-sign a loan;
• keep credit-card balances and payment timing steady;
• do not make unexplained transfers or cash deposits;
• save updated pay statements and account statements;
• report a job, compensation, debt, or occupancy change promptly; and
• respond to document requests completely and through the secure channel provided.

The CFPB confirms that a lender may obtain a credit report when you apply and again just before closing. Stability and early communication help reduce last-minute problems.
