It signals to sellers that you are a serious, qualified buyer and provides you with a clear financial picture of what you can afford. Unlike a simple prequalification, which is often a quick estimate, a preapproval involves a thorough verification of your financial health by a lender. Understanding the requirements can help you prepare effectively and strengthen your application.

Core Documentation for Mortgage Preapproval

Lenders will request a comprehensive set of documents to assess your financial stability and ability to repay a loan. Being prepared with these items will streamline the process.

1. Proof of Income and Employment
Lenders need to verify that you have a stable, reliable income.
* Recent Pay Stubs: Typically the last 30 days, showing year-to-date earnings.
* W-2 Forms: From the past two years.
* Tax Returns: Personal and business (if applicable) from the past two years.
* Proof of Additional Income: Documentation for bonuses, commissions, alimony, child support, or Social Security benefits.

2. Credit History and Score
Your credit score is a primary factor in determining your interest rate and loan eligibility.
* Credit Report Authorization: You will sign a form allowing the lender to pull your credit report from the three major bureaus (Equifax, Experian, and TransUnion).
* A Strong Credit Score: While requirements vary, a FICO score of 620 or higher is common for conventional loans, though better rates are offered for scores above 740. FHA loans may accept scores as low as 580 with a higher down payment.

3. Proof of Assets and Down Payment
Lenders must verify you have the funds for the down payment and closing costs, and that the money has been seasoned (in your account for a period of time).
* Bank Statements: Usually two months’ worth for all checking, savings, and investment accounts.
* Gift Letters: If part of your down payment is a gift from a family member, a formal letter stating the funds are a gift (not a loan) is required.
* Retirement and Investment Account Statements.

4. Debt-to-Income Ratio (DTI)
This ratio compares your monthly debt payments to your gross monthly income. Lenders use it to gauge your ability to manage monthly mortgage payments.
* Calculation: Your total monthly debt obligations (including your prospective mortgage, plus auto loans, student loans, credit card minimums, etc.) divided by your gross monthly income.
* Common Threshold: Many lenders prefer a DTI below 43%, though some programs may allow higher ratios with compensating factors like an excellent credit score.

5. Personal Identification and Information
* Government-Issued ID: Such as a driver’s license or passport.
* Social Security Number: For the credit check and application.
* Residence History: Addresses for the past two years.

The Preapproval Process:

What to Expect

Shop around with banks, credit unions, and mortgage brokers.

Provide all required documentation.

The lender will perform a hard inquiry on your credit.

A loan officer or underwriter will verify all information.

This document will state the loan amount you are conditionally approved for, the loan type, and an interest rate (sometimes estimated). It is typically valid for 60 to 90 days.

Tips for a Strong Preapproval Application

* Check Your Credit Early: Review your reports for errors and address any issues.
* Avoid Major Financial Changes: Do not open new credit lines, make large purchases on credit, or change jobs during the process.
* Gather Documents Early: Having everything organized speeds up the process.
* Be Accurate and Truthful: Inconsistencies can delay or derail your application.
