Why Mortgage Preapproval Matters
Mortgage preapproval is a conditional assessment from a lender that indicates how much you may be able to borrow for a home loan. It involves a review of your financial documentation and credit history, and it can strengthen your position when you make an offer on a home.
Having a preapproval letter shows sellers that you are a serious and prepared buyer. It also helps you focus your home search on properties within a realistic price range, potentially saving time and reducing uncertainty.

Steps to Get Preapproved
The preapproval process is straightforward when you have your information ready. Here are the typical steps, in order.
- Choose a lender: Research mortgage lenders and select one that fits your needs. You can use their online tools or visit a branch.
- Submit an application: Provide personal information, including your income, assets, and the loan amount you are seeking.
- Consent to a credit check: The lender will typically perform a hard inquiry on your credit report to assess your creditworthiness.
- Provide documentation: Submit the required documents, such as identification, pay stubs, tax returns, bank statements, and any other requested items.
- Receive your preapproval letter: If the lender approves your application, you'll get a letter stating the loan amount for which you're conditionally approved.
- Use the letter to shop for homes: Present the preapproval to real estate agents and sellers as evidence of your financial readiness.

Documents Typically Required
While the exact list can vary by lender and your financial situation, most lenders ask for the following documents when you apply for preapproval. Gathering these in advance can speed up the process.
- Government-issued identification, such as a driver's license or passport, and your Social Security number.
- Recent pay stubs, typically from the last 30 to 60 days.
- Two years of federal tax returns and W-2s, or similar income documentation.
- Recent bank statements, usually for the last two months, to verify your assets.
- If your down payment includes gifted funds, a gift letter and documentation of the transfer.
- If you are self-employed, additional documentation such as business tax returns and profit-and-loss statements.

How Lenders Evaluate Your Application
Lenders assess your preapproval application by reviewing your credit history, income, and assets. They aim to determine whether you are likely to repay the loan and how much they are willing to lend you.
A hard credit inquiry is usually part of this process. This can temporarily lower your credit score by a few points, but the impact is generally small and short-lived.
Your income documentation helps lenders verify that you have a stable source of funds to make mortgage payments. They will also look at your existing debts and monthly obligations to gauge your overall financial health.

Preapproval vs. Prequalification
Preapproval and prequalification are not the same. Prequalification is typically based on self-reported information you provide, without the lender verifying your financial details. It is a quicker, less formal estimate.
Preapproval, on the other hand, involves a thorough review of your financial documentation and credit history. It is more comprehensive and carries more weight with sellers and real estate agents.

What Preapproval Does Not Guarantee
It's important to understand that preapproval is not a final loan approval or a guarantee that your mortgage will close.
Preapproval letters also have an expiration date—typically 30 to 90 days, depending on the lender. If your letter expires, you might need to restart the process or ask for an update.
