If you've started looking at homes, you've probably heard that you need to "get preapproved" before making an offer. Then a lender's website offers to "prequalify" you in minutes, and it's fair to wonder whether those are the same thing, which one sellers want, and whether either one hurts your credit.

The short answer from the Consumer Financial Protection Bureau (CFPB): both are letters saying how much a lender is generally willing to lend you, based on certain assumptions, and neither is a guaranteed loan offer. What matters is not the label but what the lender actually checked. This guide explains how the two letters differ in practice, how credit checks work while you shop, when to get a letter, and what to do if you're declined. Any dollar examples are illustrative.

Prequalification and preapproval, defined

Comparison of prequalification and preapproval letters as the CFPB describes them: both state how much a lender is generally willing to lend based on assumptions and neither is a guaranteed loan offer, but some lenders base prequalification on unverified information you report and issue preapproval only after verifying information

The CFPB says prequalification and preapproval letters both specify how much the lender is willing to lend you, up to a certain amount and based on certain assumptions. They give useful information about your likelihood of getting a loan, but they are not guaranteed loan offers.

Where they differ is in how individual lenders use the words. According to the CFPB, some lenders offer a prequalification letter based on unverified information you report, and will only issue a preapproval letter based on verified information. In connection with either request, some lenders may issue a written commitment letter, valid for a certain period, to extend a loan up to a specified amount subject to limited conditions.

So, in everyday use:

Prequalification often means a quick estimate built on what you tell the lender about your income, debts, and savings.
Preapproval often means the lender has also pulled your credit and looked at documents, so its estimate rests on firmer ground.

"Often" is doing real work in those sentences. The CFPB's Buying a House guide notes that some lenders offer only a prequalification and others only a preapproval, and that some base preapproval letters solely on the information you provide while others dig into the details and documents up front.

Why the label matters less than the process

Five points the CFPB makes about the two terms: lenders use them differently, the label tells you little about the process, both are letters saying a lender is generally willing to lend up to an amount, neither is a guaranteed offer, and you should ask what was verified

The CFPB's advice is plain: don't worry about which word lenders use. Lenders' processes vary widely, and the words don't tell you much about a particular lender's process, even if the process may result in legal differences.

What sellers care about is confidence that you can get financing. The CFPB explains that the letter helps you make an offer because it gives the seller confidence you'll be able to get a loan, and that it should provide enough information for sellers in your area to take it seriously. The Buying a House guide adds that sellers frequently require a preapproval letter before accepting an offer. To check that your letter will do its job locally, the CFPB suggests asking a local real estate agent or a housing counselor.

The practical lesson: a letter based on verified information is generally stronger, because there are fewer surprises later. The CFPB points out that all lenders require documentation at some point if you apply, and that it's better to learn now that you need an extra document than when you're about to close.

What lenders look at

The CFPB says lenders preapprove you by looking at your income, assets, debts, and credit record. Ask each lender exactly which documents it wants; requirements differ. One number lenders will calculate is your debt-to-income ratio (DTI), which the CFPB defines as all your monthly debt payments divided by your gross monthly income. Different loan products and lenders have different DTI limits. Our debt-to-income ratio guide walks through the math with examples.

How preapproval affects your credit

How mortgage credit checks affect your score according to the CFPB: an inquiry typically has a small negative effect, multiple mortgage checks within a 45-day window are recorded as a single inquiry, checking your own credit has no effect, and applying for other credit adds separate inquiries

Lenders typically check your credit before issuing a preapproval, according to the CFPB, and they may check it for a prequalification too. Here's what that does to your scores.

Each lender credit check is an inquiry. The CFPB says an inquiry typically has a small negative effect on your credit scores and is visible to other lenders.
Mortgage shopping is treated as one event. Within a 45-day window, multiple credit checks from mortgage lenders are recorded as a single inquiry, the CFPB explains, because lenders know you're only buying one home. The impact is the same no matter how many lenders you consult, as long as the last check is within 45 days of the first.
Scoring models allow for shopping. In a separate answer, the CFPB says inquiries within 14 to 45 days of each other for the same type of loan are generally treated as no more than a single inquiry, and for the most common scoring models, mortgage-related inquiries in the 30 days before scoring have no effect at all.
Other credit is different. Applying for a credit card, car loan, or other loan adds a separate inquiry, so the CFPB suggests avoiding new credit right before or during the mortgage process.
Your own checks are free of impact. Checking your own credit report or score doesn't affect your scores.

Even if a lender needs to check your credit after the 45-day window, the CFPB says shopping around is usually still worth it: the extra inquiry has a small effect, while a better deal can save a lot over time. For more on how inquiries work, see our guide to hard vs soft inquiries.

When to get preapproved

Timeline of where a preapproval fits in buying a home: check your credit reports, get preapprovals from several lenders, shop for homes while the letter is valid for typically 30 to 60 days, make an offer, then request Loan Estimates and choose a lender

Timing involves a trade-off. The CFPB notes that preapproval letters can carry an expiration date, typically 30 to 60 days, and that lenders usually check your credit. For those reasons, many people wait until they're ready to shop seriously for a home.

But there's a good argument for starting earlier. The CFPB says getting preapproved earlier in the process can be a good way to spot potential issues with your credit in time to correct them. A middle path many buyers use:

Months before you shop: pull your free credit reports and fix any errors. Our guides cover how to check your credit score and get free reports and how to dispute credit report errors.
When you're ready to tour homes: request preapprovals from several lenders in a short span, so the credit checks fall inside the 45-day window.
If your search runs long: ask the lender to refresh the letter before it expires.

Shop at least three lenders

The CFPB's Shopping for a Mortgage guide recommends asking at least three different lenders for preapproval. It explains that preapproval lets you "try out" each lender to see what loans and prices it offers, and that getting all three within a short time should have no major impact on your credit score. Contact banks, credit unions, and organizations that specialize in situations like first-time buyers or veterans.

A preapproval is not a loan approval

This is where buyers most often get tripped up. The CFPB's Buying a House guide says getting a preapproval letter isn't the same thing as applying for a loan. The letter just says a lender is willing to lend to you, pending further confirmation of details.

It also doesn't lock you into that lender. According to the CFPB, preapproval letters don't give you enough information to decide which lender offers the best deal, and getting one doesn't commit you. The CFPB suggests waiting to choose a lender until you've made an offer on a house and received official Loan Estimates from each potential lender. A Loan Estimate is the standard three-page form a lender must send within three business days of your application; even then, the CFPB notes, the lender hasn't yet approved or denied your loan.

Things can still change between preapproval and closing. The CFPB's rate-lock answer lists common reasons a rate can change even after it's locked: you change the kind of loan or your down payment, the appraisal comes in higher or lower than expected, your credit score changes because you took out a new loan or missed a payment, or the lender can't document overtime, bonus, or other income. Avoid applying for new credit while you're under contract, and ask about a rate lock once you have an accepted offer.

The preapproval amount is a ceiling

The CFPB is emphatic that you're the only one who can decide how much to spend. Lenders look at income, assets, debts, and credit, but your financial life is more complicated than that. Its answer on affordability says to focus on a mortgage that's affordable given your other priorities, not on how much you qualify for.

In the illustrative chart above, a buyer preapproved for up to $350,000 has set a $300,000 budget of their own. The CFPB's guidance for that situation: use the letter to shop without changing your target price, and tell your real estate agent if you don't want to see homes above a certain amount. If you were preapproved for less than you hoped, ask the lender which factor limited the amount, such as income, and adjust expectations if needed.

Questions to ask each lender

Four questions to ask a lender when you request a preapproval: what information will you verify, what assumptions did you make, how long is the letter valid, and is there anything that could lead to denial or higher costs later

The CFPB suggests finding out each lender's preapproval process and what documentation it requests, and then asking what assumptions it made. Good questions include:

What did you verify, and what did you take from my own answers?
Which documents will you need now, and which later?
What interest rate, down payment, and debt figures did you assume?
When does this letter expire, and how do I refresh it?
Is there anything about my situation that could lead to denial later, or raise my rate or costs?
Does your letter include a written commitment, and on what conditions?

Write the answers down. When you compare lenders later, you'll know whose letter rests on verified information and whose is closer to a quick estimate.

If you're declined

Five steps if a preapproval is declined, drawn from the CFPB: ask why, review the adverse action notice, ask for the credit score used, get credit report errors corrected, and contact a HUD-approved housing counselor

A "no" at the preapproval stage is useful information, and you have rights. The CFPB says that even if you haven't submitted a formal application, a lender that evaluates your creditworthiness and tells you that you don't qualify for a prequalification or preapproval letter must give you an adverse action notice.

The CFPB's next steps:

Ask the lender to explain why you were declined. Was it your credit score, or specific negative information on your report?
Ask to see the credit score used. If the lender used your score to deny the request, it must send you a notice with that score and instructions for getting a free copy of your credit report.
Get any errors on your credit report corrected.
For help improving your credit, contact a HUD-approved housing counseling agency, online or at 1-800-569-4287.

Then try again once the issue is fixed, or ask another lender. Requirements vary between lenders and loan programs.

FAQ

Is preapproval better than prequalification?

Not automatically. The CFPB says lenders use the terms differently and the label tells you little about the process. A letter based on verified income, assets, and credit is generally more reliable, so ask what each lender checked.

Does getting preapproved hurt my credit?

A lender's credit check is an inquiry that typically has a small negative effect, the CFPB says. Multiple mortgage credit checks within a 45-day window are recorded as a single inquiry, so you can compare several lenders.

How long does a mortgage preapproval last?

The CFPB says preapproval letters can have an expiration date, typically 30 to 60 days. If your search takes longer, ask the lender to update the letter.

Do I have to use the lender that preapproved me?

No. The CFPB says a preapproval doesn't commit you to that lender. Wait to choose until you've made an offer and compared official Loan Estimates.

Can I be denied after preapproval?

Yes. A preapproval is not a loan approval or a guaranteed offer. It depends on assumptions and on details being confirmed, such as your income, credit, and the property's appraisal.

What happens if I'm denied a preapproval?

The CFPB says a lender that evaluates your creditworthiness and denies the letter must send an adverse action notice. If your credit score was used, you're entitled to see that score and learn how to get a free credit report.

How many lenders should I get preapproved with?

The CFPB's Shopping for a Mortgage guide recommends at least three. Getting them within a short time should have no major impact on your credit score.
