I just got preapproval for a mortgage — How long does it last?

But how long does a preapproval for a mortgage last?

After all, circumstances can change — your financial situation, for instance, or the economy as a whole — and you can’t expect a preapproval to last forever.

Here's a look at how to get a preapproval, how long it lasts and what to do if it expires.

How long does a mortgage preapproval last?

Most preapprovals are good for 60 to 90 days, but some may expire in as little as 30 days. How long your mortgage preapproval is good for will depend on the mortgage lender. Your financial situation may change, your lender’s financial situation may change and/or the state of the economy itself may change. Because of this, preapprovals are valid for only a set timeframe.

That means no time for dilly-dallying. Armed with your preapproval, it’s time to initiate full-on house-hunting mode.

It would be a shame if your preapproval were to expire just as you found your dream home.

What is a mortgage preapproval?

A mortgage preapproval is a letter from your lender stating the estimated amount you’ll be able to borrow. The letter also specifies the type of loan, interest rate and other terms.

This does not guarantee approval for a mortgage (hence the name, preapproval). Rather, it’s an educated guess.

To estimate the loan amount, lenders take a bird’s eye view of your financial situation. They look over your credit history, credit score, income, assets, debts and employment history to determine how much you can afford.

Once your offer is accepted on a house, they will appraise the home and take a deeper look into your finances to determine final approval.

Do you need a preapproval for a mortgage?

It’s worth noting that you are not required to get preapproved in order to buy a house. But as you’re about to see, it’s almost always a good idea.

Without a preapproval, you won’t have a clear idea of how much lenders are willing to lend you. That means you could waste your time searching for, touring, negotiating and closing on properties that aren’t even in your price range.

And you won’t just waste your own time.

If you try to close on a house and your mortgage application is denied, you also will have wasted the seller’s time.

Because of this, many sellers won’t take your offer seriously unless you have a preapproval to back it up. This is especially true in a hot seller’s market.

Think about it: If a home attracts multiple competitive offers backed by preapprovals, why would the owners risk selling to someone without one?

As you can see, it almost always makes sense to get preapproved.

The only time it might not be necessary is if you’re a low-risk borrower buying a home well below your means in a slow market. That, or you’re buying with cash, of course.

How to get a preapproval for a mortgage

To get a preapproval for a mortgage, you’ll need to submit a mortgage application to a lender.

This involves gathering documentation to prove your identity, employment, income, assets and debts. You’ll need:

• A social security card
• Bank account statements or a proof-of-funds letter
• W-2 statements, pay stubs, tax returns and other documents showing proof of a steady income
• Anything else your lender requests

Digging for information and collecting these documents may seem tedious, but it will make life easier when the time comes to close on a property.

After you submit your documents, your lender will have your information on file, and you’ll have one less task to juggle during the closing process.

Keep in mind that, to get the best mortgage rates, you will want to be preapproved by multiple lenders. This will allow you to compare lenders and shop around for the best loan terms. The good news is that once you gather all your documentation, applying to additional lenders won’t take much extra time.
