Once you've compared prequalification offers and picked the best one, it's time to formally apply. This triggers a hard inquiry on your credit report. A single hard inquiry typically has a small, temporary effect — usually less than 5 points and it recovers within a few months.
Rate shopping protection: If you apply to multiple lenders within a 14-to-45-day window (depending on the scoring model), all those hard inquiries for the same type of loan count as a single inquiry for scoring purposes. This means you can apply to your top two or three choices without stacking penalties — just do it within the same two-week period.
What happens after you apply:
1. Verification. The lender reviews your documents and may ask for additional information. Common requests include a letter of explanation for gaps in employment, additional bank statements, or verification of your identity.
2. Underwriting. The lender evaluates your risk. This can take anywhere from a few minutes (some online lenders use automated underwriting) to a few days (traditional banks and credit unions). Don't make large purchases, open new credit accounts, or change jobs during this period — all of those can change your risk profile.
3. Conditional approval or denial. If approved, you'll receive a loan agreement with the final terms. Read every page. Compare the final APR, fees, and terms to what was shown in prequalification. If the numbers changed significantly, ask why.
4. If denied: the lender must send you an adverse action notice explaining why, under the FCRA. Common reasons include DTI too high, credit score too low, insufficient income, or too many recent inquiries. This notice tells you exactly what to work on before trying again.
Before you sign: Calculate the total cost of the loan. Multiply the monthly payment by the number of months. That total is how much you'll actually pay — and it will always be more than the amount you borrowed. Make sure you're comfortable with the total amount, not just the monthly number.
