What a preapproval actually is

It's a lender telling you, in advance of any particular car, roughly what it would be willing to lend you and on what terms, based on what it knows about you so far. Usually that means a maximum amount, a rate or a range of rates, a term, and an expiry date. The key words are "so far." It is a conditional offer built on your application and your credit file, not on the car you haven't picked yet.

Closer to a reservation with conditions attached. A coupon is good for anyone who holds it. A preapproval is good for you, for a limited time, provided the things the lender hasn't checked yet come back the way you said they would. That usually includes proof of income, sometimes employment or residence, and always the car itself: its price, age, mileage and value relative to what you're borrowing.

In theory, prequalification is the lighter version: a quick estimate, often based on information you supply and sometimes a soft look at your credit. Preapproval is the heavier one, usually involving a fuller application and often a hard inquiry. In practice, lenders and websites use the two words loosely and sometimes interchangeably. So I'd stop caring about the label and ask three plain questions instead. Did you pull my credit, and was it a hard or soft inquiry? Is there an actual rate attached, in writing? What would have to be true for this to turn into a loan?

A hard inquiry can have a small effect on some scores, and it shows up on your report for a while. A soft inquiry doesn't affect scores. The lender should be able to tell you which it will use before you consent. On shopping around: credit scoring models have generally been built to recognize rate shopping for a car loan, grouping several auto-loan inquiries made within a limited window and treating them more like one. How long that window is depends on the scoring model, so the practical advice is simply to do your comparing within a short, deliberate stretch rather than spreading applications over months.

Because a preapproval turns financing from something you're told into something you can compare. Walk in with a written offer, and when the finance office presents its terms you have a benchmark. If theirs is better, take it. If it isn't, you already have an alternative and don't have to decide under pressure at the end of a long afternoon.

It also changes the conversation. Without a benchmark, it's easy for talk to drift toward the monthly payment, which can be lowered by stretching the term without the deal getting any cheaper. With one, you can talk about the price of the car and the APR as separate things, which is how they ought to be discussed.

You found out the dealer's offer was genuinely good, which you otherwise could only have hoped. That's the whole value of a benchmark. When comparing, compare like for like: same amount financed, same term, and look at the APR and the total of payments on the actual contract rather than the payment alone. Reading a retail installment contract shows where those two figures sit on the page.

It can. If the car you choose is older, has more miles, or costs more relative to its value than the lender assumed, the terms may shift or the lender may decline that particular car. If what you stated about income doesn't verify, same story. And offers expire. The written preapproval should say what can change it; if it doesn't, ask the lender directly and get the answer in writing.

Generally, no. A preapproval is an offer to you, not a commitment from you. You can let it expire. That said, read what you're given; if any fee or deposit is involved, understand what it's for before paying it.

Your credit history, your income against your existing debts, and later the car and how much you're borrowing against it. The credit part is its own subject, taken section by section in how a car lender reads your credit. It is worth pulling your own reports before you apply, so nothing on them surprises you in front of a loan officer.

It's information, not advice. The maximum is the lender's estimate of what it would be comfortable lending. It knows nothing about your childcare, your rent increase next spring, or the fact that you'd like to save for something that isn't a car. Set your own ceiling before you look at theirs. Three numbers to set before you shop is one way to do that: an all-in price, a maximum payment, and a point at which you walk away.

Treat the preapproved amount as the outer wall of the room, not the size of the furniture.
