Mortgage Preapproval: What It Proves and What Comes Next

A preapproval letter can help you shop for a home, but it is not a reason to stop checking your finances or reading the loan terms. The lender still needs to evaluate the application and the property. Understand how prequalification differs from preapproval, what a formal application involves, and what to ask if the lender turns you down.

The questions below use selected Consumer Financial Protection Bureau guidance, adapted and organized by Fynoptic. Source links and the dates displayed by those sources are provided at the end.

What’s the difference between a prequalification letter and a preapproval letter?

Prequalification and preapproval letters both specify how much the lender is willing to lend to you, up to a certain amount and based on certain assumptions. These letters provide useful information about your likelihood of getting a loan but are not guaranteed loan offers.

Lenders use the terms “prequalification” and “preapproval” differently. Some lenders may use the word “prequalification,” while other lenders may call the letter a “preapproval.” Some lenders offer a prequalification letter based on unverified information that you report and will only issue a preapproval letter based on verified information. In connection with a prequalification or preapproval request, some lenders may issue a written commitment letter valid for a certain period of time to extend a loan up to a specified amount subject to limited conditions.

Don’t worry about which word lenders use. Lenders’ processes vary widely, and the words they use don’t tell you much about a particular lender’s process even if it may result in legal differences. Both terms refer to a letter from a lender that says the lender is generally willing to lend to you, up to a certain amount and based on certain assumptions. This letter helps you to make an offer on a home, because it gives the seller confidence that you will be able to get financing to buy the home. It is not a guaranteed loan offer, but it should provide enough information for sellers in your area to take it seriously. The best way to make sure that the letter you have will serve its purpose is to ask a local real estate agent or a housing counselor.

Lenders may check your creditwhen issuing a prequalification or preapproval letter. Many people wait to get a preapproval letter until they are ready to begin shopping seriously for a home. However, getting preapproved earlier in the process can be a good way to spot potential issues with your credit in time to correct them. In addition, even if you have not submitted a formal loan application, a lender that evaluates your creditworthiness and tells you that you do not qualify for a prequalification or preapproval letter must provide you with an adverse action notice.

What do I have to do to apply for a mortgage loan?

To apply for a mortgage loan, you will have to provide a lender with personal financial information and information about the house you want to finance.

The first step of applying for a mortgage is to request a Loan Estimate from three or more lenders.

To receive a Loan Estimate, you need to submit only six key pieces of information:

  • Your name
  • Your income
  • Your Social Security number (so the lender can check your credit)
  • The address of the home you plan to purchase or refinance
  • An estimate of the home's value
  • The loan amount you want to borrow

Although you're not required to provide documents in order to get a Loan Estimate, it's a good idea to share what you have with the lender(s). The more information the lender has, the more accurate your Loan Estimate will be.

Tip: It's a good idea to request Loan Estimates from several lenders. That way, you can compare your options and choose the best loan for you. Each lender is required to send you a Loan Estimate within three business days of receiving your six key pieces of information.

Once you're ready to choose a loan offer, you need to notify the lender that you are ready to proceed with the loan application. If you don't notify a lender that you'd like to proceed within 10 business days, the lender may revise the Loan Estimate or close your application as incomplete and you may need to start over. The 10 business days are calculated from when the lender delivers the Loan Estimate to you or places it in the mail, whichever is earlier.

Once you've notified the lender that you would like to proceed with an application, the lender may ask you to provide additional information and documents to verify the information you have already submitted. The lender processes this information and may follow up with you to request additional information or clarification. Once the lender has received all the necessary information, the lender approves or denies your loan application.

I applied for a mortgage loan and my lender denied my application. What can I do?

You should request an explanation from your lender as to why your application was denied. The lender is required to provide you this explanation in writing if you request it, and must to give you copies of the credit score upon which the denial was based.

Don’t be discouraged. Another lender may approve you for a loan.

In addition, you may want to examine your credit by obtaining a credit report at no cost to you if you have not already done so to make sure there are no mistakes. You may also want to talk to a U.S. Department of Housing and Urban Development (HUD)-approved housing counselor who can help you evaluate your ability to pay for a mortgage loan.

What is a debt-to-income ratio?

Your debt-to-income ratio (DTI) is all your monthly debt payments divided by your gross monthly income. This number is one way lenders measure your ability to manage the monthly payments to repay the money you plan to borrow.

Different loan products and lenders will have different DTI limits.

How do I calculate my debt-to-income ratio?

To calculate your DTI, you add up all your monthly debt payments and divide them by your gross monthly income. Your gross monthly income is generally the amount of money you have earned before your taxes and other deductions are taken out. For example, if you pay $1500 a month for your mortgage and another $100 a month for an auto loan and $400 a month for the rest of your debts, your monthly debt payments are $2,000. ($1500 + $100 + $400 = $2,000.) If your gross monthly income is $6,000, then your debt-to-income ratio is 33 percent. ($2,000 is 33% of $6,000.)

What is the ability-to-repay rule?

The ability-to-repay rule prohibits most lenders from giving you a mortgage unless they have made a reasonable and good faith determination that you are able to pay back the loan.

Under the rule, lenders must generally find out, consider, and document a borrower’s income, assets, employment, credit history, and monthly expenses. Lenders cannot just use an introductory or “teaser” rate to figure out if a borrower can repay a loan. For example, if a mortgage has a low interest rate that goes up in later years, the lender has to make a reasonable effort to figure out if the borrower can pay the higher interest rate too.

One way a lender can follow the ability-to-repay rule is by making a "Qualified Mortgage."
