Mortgage Preapproval vs. Prequalification: What the Letter Tells a Seller
Mortgage preapproval vs. prequalification: what each letter means, why lenders use the terms differently and how credit checks work while you shop around.
The difference between mortgage preapproval and prequalification is smaller, and less standardized, than many home buyers expect. According to the Consumer Financial Protection Bureau, both are letters from a lender saying it is generally willing to lend up to a certain amount based on certain assumptions, and neither is a guaranteed loan offer.
What is the difference between preapproval and prequalification?
The CFPB says lenders use the two words differently. Some issue a prequalification based on unverified information the buyer reports and reserve the word preapproval for a letter based on verified information, such as documented income and assets. Others use the terms interchangeably. Some lenders also issue a written commitment, valid for a set period, to lend up to a specified amount subject to limited conditions.
The bureau's advice is not to focus on which word appears at the top of the letter, because the label alone says little about how thoroughly the lender reviewed a buyer's finances. The more useful question is what the lender actually checked. Whatever it is called, the letter is not loan approval; the loan is still subject to underwriting and approval.
Why sellers ask for a letter
A preapproval or prequalification letter helps a buyer make an offer because it gives the seller some confidence the buyer can get financing, the CFPB says. The bureau suggests asking a local real estate agent or a housing counselor whether a letter will be taken seriously in a given market.
Getting a letter early can also surface problems in time to fix them. The CFPB notes that preapproval can be a good way to spot credit issues before serious shopping begins, and that a lender that evaluates a buyer's creditworthiness and says the buyer does not qualify for a letter must provide an adverse action notice. Buyers can review the Iron Hill Mortgage home buying overview and estimate a comfortable price range with the home affordability calculator before they apply.
How credit checks work while you shop
A lender's credit check is recorded as an inquiry, which typically has a small negative effect on credit scores, according to the CFPB. Shopping among mortgage lenders does not multiply that effect: within a 45-day window, multiple credit checks from mortgage lenders are recorded as a single inquiry, so buyers can collect several preapprovals and official Loan Estimates. Checking your own credit report or score does not affect your scores.
The bureau also advises avoiding applications for other credit, such as a credit card or car loan, right before or during the mortgage process, because each one adds an inquiry.
Frequently asked questions
Is a preapproval a loan approval? No. The CFPB describes both prequalification and preapproval letters as useful indications of the likelihood of getting a loan, not guaranteed loan offers. A letter is not a commitment to lend: any loan remains subject to approval, which depends on the full application, verification of the buyer's information, the property and underwriting.
Will getting preapproved by more than one lender hurt my credit? Mortgage credit checks made within a 45-day window count as a single inquiry, according to the CFPB, so comparing lenders in that period has the same credit impact as using one.
When should I get a preapproval letter? Many buyers wait until they are ready to shop seriously, the CFPB says, though getting one earlier can reveal credit issues while there is still time to correct them.
