Mortgage Pre-Approval Guide

Back to our main guide: The Ultimate First-Time Home Buyer Checklist.

The Difference Between Pre-Qualification and Pre-Approval

Before you start seriously house hunting, you need to know exactly how much you can afford and prove to sellers that you are financially capable of closing the deal. This is where the mortgage pre-approval process comes in. However, many first-time buyers confuse pre-qualification with pre-approval.

Pre-Qualification is a preliminary step. It involves providing a lender with an overview of your financial picture, including your debt, income, and assets. The lender reviews this self-reported information and gives you an estimate of how much you might be able to borrow. It is a quick process, often done online or over the phone, and usually does not require a hard credit pull. While helpful for getting a rough idea of your budget, a pre-qualification letter carries very little weight with sellers because the information hasn't been verified.

Pre-Approval, on the other hand, is a formal and rigorous process. You must submit official financial documents, and the lender will perform a hard inquiry on your credit report. They will thoroughly evaluate your financial history, creditworthiness, debt-to-income ratio, and employment status. If approved, you will receive a formal letter stating exactly how much the lender is willing to loan you, at what interest rate, and under what terms. In a competitive housing market, a pre-approval letter is absolutely essential; most sellers will not even consider an offer without one.

The Document Checklist: What You Need to Apply

Getting pre-approved requires gathering a significant amount of paperwork. To make the process as smooth as possible, collect these documents before you contact a lender:

How Pre-Approval Impacts Your Credit Score

Many buyers hesitate to get pre-approved because they fear the credit check will lower their score. When a lender checks your credit for a mortgage pre-approval, it results in a "hard inquiry" (or hard pull). A hard inquiry will temporarily ding your credit score, usually by about 3 to 5 points.

However, the credit bureaus understand that consumers need to shop around for the best mortgage rates. Because of this, they group multiple mortgage inquiries that occur within a specific timeframe (usually 14 to 45 days, depending on the credit scoring model used) into a single inquiry for scoring purposes. This means you can—and should—apply with three or four different lenders within a two-week window to compare rates without destroying your credit score.

Once you are pre-approved, it is critical that you do not make any major financial changes. Do not apply for new credit cards, do not buy a car, do not co-sign a loan for a friend, and do not change jobs if possible. Any of these actions can change your credit profile and debt-to-income ratio, potentially causing your lender to revoke your pre-approval right before closing.

How Long Does Pre-Approval Last?

A mortgage pre-approval is not open-ended. Financial situations change, and so do economic conditions and interest rates. Therefore, most pre-approval letters are valid for a specific timeframe, typically 60 to 90 days.

If you have not found a home and gone under contract within that window, your pre-approval will expire. Fortunately, renewing it is usually much simpler than the initial application. You generally just need to provide your lender with updated pay stubs and bank statements, and they will run another credit check to ensure your financial situation hasn't deteriorated.

If interest rates have risen significantly since your initial pre-approval, your maximum borrowing amount may decrease when you renew, as your projected monthly payment will now be higher.
