- Shopping around with at least three to five mortgage lenders can save you thousands of dollars over the life of your new loan.
- The rate shopping window does not expire in the traditional sense, but you must submit all applications within the defined period for them to count as one inquiry.
- Prequalification often uses a soft credit check that does not affect your credit score, while preapproval requires a hard credit pull.
- Use Wirly’s refinance calculator and break-even calculator to compare offers before committing to a lender.
If you want to refinance your mortgage at the lowest possible interest rate, you need to compare offers from multiple lenders. The good news is that credit scoring models are designed to let you do exactly that without wrecking your credit score. The refinance rate shopping window is a specific time period – usually 45 days under the most common FICO scoring model – during which all hard inquiries for the same type of loan count as just one inquiry on your credit report.
This means you can apply with several mortgage lenders, compare their rates and fees, and choose the best deal – all while minimizing the impact on your credit. According to the Consumer Financial Protection Bureau, shopping around for a mortgage loan will help you get the best deal, and they recommend contacting multiple banks, credit unions, and brokers to compare rates, fees, and annual percentage rates (APR). Below, we break down exactly how the rate shopping window works, how to use it strategically, and what pitfalls to avoid.
What Is Rate Shopping?
Rate shopping is the process of applying with multiple lenders to compare interest rate offers for the same type of loan. When you refinance, each lender will pull your credit report and run a hard credit check to assess your creditworthiness. Without the rate shopping window, each of those hard inquiries would individually ding your credit score.
Credit scoring models recognize that applying with several mortgage lenders is smart consumer behavior, not a sign of financial desperation. So FICO and VantageScore both include a rate shopping provision that groups applications within a defined window into a single inquiry for scoring purposes.
How Does the Rate Shopping Window Work?
The mechanics are straightforward but important to understand. When you submit a mortgage refinance application, the lender pulls your credit report, creating a hard inquiry. If you submit additional applications within the rate shopping window, those extra inquiries are bundled together and treated as one.
The 45-Day Window Under FICO
The most widely used FICO scoring models (FICO Score 8 and newer) use a 45-day window. This means all mortgage-related hard inquiries that occur within a 45-day period are counted as a single inquiry when calculating your credit score. Older FICO models (such as FICO Score 2, which some mortgage lenders still use) may use a shorter 14-day window.
VantageScore models use a 14-day rolling window for rate shopping across all loan types. Since you may not know which scoring model your lender uses, the safest strategy is to complete all your rate shopping within 14 days. That way, you are covered regardless of the scoring model in play.
What Types of Loans Qualify?
The rate shopping window applies to specific loan types, including:
- Mortgage loans (purchase and refinance)
- Auto loans
- Student loans
It does not typically apply to credit card applications or personal loans. Whether you are pursuing a standard refinance, a cash-out refinance, or switching your loan term from a 30-year mortgage to a 15-year term, the window applies as long as the inquiries are coded as mortgage-related.
Prequalification vs. Preapproval
Before diving into full applications, it helps to understand the difference between prequalification and preapproval, because they affect your credit differently.
Prequalification is usually a preliminary estimate based on self-reported financial information. Most lenders perform only a soft credit check during prequalification, which does not affect your credit score at all. This is a useful first step to narrow down your list of lenders.
Preapproval is a more thorough process. The lender will verify your income, assets, and debt, and they will perform a hard credit pull. This is the step that triggers the hard inquiry on your credit report – and the step where the rate shopping window becomes relevant.
A smart strategy is to prequalify with several lenders first, then submit formal applications within the 45-day window only to those offering competitive rates.
How Do Hard Inquiries Affect Your Credit Score?
A single hard inquiry typically lowers your FICO score by fewer than five points, according to FICO’s own published guidance. Hard inquiries remain on your credit report for two years but only affect your credit score for 12 months.
When you shop around for a mortgage refinance within the rate shopping window, all those inquiries count as one. So instead of seeing your score drop by a few points for each application, you experience only one small dip. This is why the window exists – to encourage consumers to compare and find the best rate without penalty.
New Credit and Your Score
The “new credit” category makes up roughly 10% of your FICO score calculation. This category considers both hard inquiries and recently opened accounts. While the inquiry impact is minimal when you use the rate shopping window, opening the new loan itself (the refinance) will also show up as new credit. This is normal and temporary – your score should recover within a few months of consistent payments.
Rate Shopping Strategies
Here is a step-by-step approach to make the most of the rate shopping window when you refinance.
Step 1: Check Your Credit Before You Apply
Before any lender pulls your credit report, check your credit yourself. You are entitled to a free credit report from each of the three major bureaus (Equifax, Experian, and TransUnion) through AnnualCreditReport.com. Review your reports for errors, outdated accounts, or incorrect balances. According to CFPB guidance, disputing errors before applying can help ensure you receive the most accurate rate quotes.
Step 2: Get Prequalified With Multiple Lenders
Start by getting prequalified with five or more lenders. Since prequalification usually involves only a soft credit check, this stage has no impact on your score. Use these preliminary quotes to create a short list of lenders worth pursuing.
According to the Consumer Financial Protection Bureau, you should ask each lender for a list of current interest rates, the fees they normally charge, and the APR for each loan product. The APR is especially important because it includes both the interest rate and certain fees, giving you a more complete picture of the loan’s true cost.
Step 3: Submit Formal Applications Within 14 Days
Once you have your short list, submit formal applications to at least three to five lenders. While the FICO 45-day window gives you generous room, aim to complete all applications within 14 days. This ensures coverage under both FICO and VantageScore models, regardless of which credit scoring model your lender uses.
Step 4: Compare Loan Estimates Side by Side
Each lender is required to provide you with a standardized Loan Estimate within three business days of receiving your application. This document shows your estimated interest rate, monthly payment, closing costs, and other key terms. Compare these documents carefully.
Pay attention to more than just the interest rate. The total closing costs, origination fees, discount points, and third-party fees all matter. Use Wirly’s refinance calculator to model different scenarios and our break-even calculator to determine how long it will take for your savings to exceed your refinance costs.
Step 5: Lock Your Rate
Once you have chosen a lender, ask about their rate lock policy. A rate lock guarantees your interest rate for a set period (typically 30 to 60 days) while your loan is processed. Ask whether there is a float-down option that lets you benefit if mortgage rates drop before closing.
What Are the Benefits of Rate Shopping?
The financial case for comparing lenders is compelling. Even a small difference in interest rate can translate into significant savings over the life of a home loan.
- Lower interest rate: Even a 0.25% reduction on a 30-year mortgage can save you tens of thousands of dollars over the full loan term.
- Lower closing costs: Lenders vary widely in what they charge. Shopping around lets you spot outliers.
- Better loan terms: You may discover that one lender offers more favorable terms for your specific situation, whether that is a cash-out refinance, a shorter loan term, or a specific type of loan like an FHA or VA refinance.
- Negotiating leverage: When you have multiple offers in hand, you can ask lenders to match or beat a competitor’s rate.

Risks and Considerations
Refinancing is not always the right move, even if you find a great rate. Before you proceed, consider these important factors.
When Refinancing Does Not Make Sense
- You plan to move soon: If you are selling your home within a few years, you may not reach the break-even point where your savings exceed closing costs.
- Your break-even period is too long: Use our break-even calculator to determine how many months it takes to recoup costs. If that number exceeds your expected time in the home, refinancing may not pay off.
- You are far into your current loan: Refinancing a mortgage resets your amortization schedule. If you are 15 years into a 30-year mortgage and refinance into a new 30-year mortgage, you restart the clock and may pay significantly more in total interest – even at a lower rate.
Hidden Costs to Watch For
- Appraisal fees: Most refinances require a new home appraisal, which can cost $300 to $600 or more.
- Title insurance and search fees: These protect the lender against title defects and can add $500 to $1,500 to your costs.
- Prepayment penalties: Some existing mortgage loans carry penalties for paying off the loan early. Check your current loan documents before applying.
- Origination fees: Some lenders charge 0.5% to 1% of the loan amount as an origination fee.
Credit Score Considerations
While the rate shopping window protects you from multiple inquiry damage, there are still credit-related factors to keep in mind. If you submit applications within the window but also apply for new credit cards or other loans outside of it, those additional hard inquiries will count separately and could affect your credit score. Keep your credit activity focused during this period.
Rate Lock Risks
If your rate lock expires before closing, you may lose your locked rate and be subject to current mortgage rates – which could be higher. Make sure you understand the lock period and any extension fees. Ask your lender whether they offer a float-down option in case rates drop after you lock.
Common Questions About the Rate Shopping Window
According to CFPB complaint data from 2024, issues related to applying for a mortgage or refinancing an existing mortgage accounted for a notable share of consumer complaints across major servicers. Being informed about the process – including the rate shopping window – can help you avoid common frustrations.
Frequently Asked Questions
Does the refinance rate shopping window expire?
The window itself does not expire in the way a coupon does. It is a rolling period that starts with your first mortgage-related hard inquiry. You have 45 days from that first pull (under FICO 8 and newer) to submit additional applications within the same window. After 45 days, new inquiries would count separately.
Do all credit scoring models use the same rate shopping window?
No. FICO Score 8 and newer models use a 45-day window. Older FICO models (like FICO 2, 4, and 5, which are still used in some mortgage lending) use a 14-day window. VantageScore models typically use a 14-day window. To be safe, try to complete all your applications within 14 days.
Will rate shopping for a cash-out refinance work the same way?
Yes. Whether you are doing a standard rate-and-term refinance or a cash-out refinance, the hard inquiries are coded as mortgage loan inquiries. The rate shopping window applies the same way for any mortgage-related application.
How many lenders should I apply with during the rate shopping window?
According to the CFPB, you should contact multiple banks, credit unions, and brokers to compare. Most experts recommend getting quotes from at least three to five lenders. More quotes give you better leverage and a clearer picture of the market. You can start by visiting our best refinance lenders page.
Can I rate shop if my credit score is low?
Absolutely. Rate shopping is especially important if your credit score is on the lower end, because rate differences between lenders tend to be larger for borrowers with lower scores. Just be sure to check your credit report for errors before applying, and submit all applications within the shortest window possible to protect your score.
