Refinance With Student Loans: A Complete Guide

If you carry student loan debt and also have a mortgage, you may be wondering whether it makes sense to refinance your student loans, your mortgage, or both. The short answer: refinancing student loans can lower your monthly payment and reduce total interest costs, which in turn improves the debt-to-income ratio lenders use when you apply for a mortgage refinance. However, this strategy involves tradeoffs – especially if you hold federal student loans with protections you would lose by refinancing into a private loan.

This guide walks through how student loan refinancing works, how it interacts with mortgage refinancing, and what to consider before making a decision.

What Does It Mean to Refinance Student Loans?

When you refinance student loans, a private lender pays off your existing student loan (or multiple loans) and issues you a new refinance loan. The new loan comes with its own interest rate, loan term, and monthly payment amount. The goal is typically to secure a lower interest rate, reduce your monthly payment, or combine multiple loans into one simplified payment.

Student loan refinancing is different from federal student loan consolidation. With a Direct Consolidation Loan from the federal government, you combine federal loans into one federal loan – but your interest rate is simply the weighted average of your existing rates, rounded up. According to the Consumer Financial Protection Bureau, consolidation does not lower your interest rate. Refinancing through a private lender, on the other hand, can potentially offer a lower interest rate based on your current creditworthiness.

Why Refinance Student Loans?

There are several reasons borrowers choose to refinance their student loans:

• Lower interest rate: If your credit score has improved since you first took out your loans, or if market rates have dropped, you may qualify for a lower interest rate than your current loan carries.
• Lower your monthly payment: Extending your loan term can reduce your monthly obligation, freeing up cash flow for other goals like saving for a home or managing mortgage payments.
• Pay off debt faster: Conversely, choosing a shorter loan term with a lower rate can help you pay less total interest over the life of the loan.
• Simplify loan payments: If you have multiple loans with different servicers, refinancing lets you combine them into one monthly payment.
• Switch rate types: You can move from a variable rate to a fixed rate (or vice versa) depending on your risk tolerance and market conditions.

What Types of Student Loans Can Be Refinanced?

Most types of student loans are eligible for refinancing through private lenders. This includes both federal and private student loans:

• Federal Direct Subsidized and Unsubsidized Loans
• Federal Direct PLUS Loans
• Parent PLUS Loans
• Federal Perkins Loans
• Private student loan products from banks, credit unions, and online lenders

Yes, banks do refinance student loans. Many major banks, credit unions, and online lenders offer student loan refinance products in the USA. Lenders like SoFi, for example, are active in both the student loan and mortgage spaces. According to CFPB complaint data for 2024, SoFi received just 23 mortgage-related complaints with a 100% timely response rate, suggesting relatively strong customer service in their lending operations.

A Critical Warning About Federal Student Loans

When you refinance a federal student loan into a private student loan, you permanently lose access to federal benefits. These include income-driven repayment plans, Public Service Loan Forgiveness (PSLF), federal forbearance and deferment options, and any future federal relief programs. According to the CFPB, borrowers should carefully weigh these protections before refinancing federal loans with a private lender. If there is any chance you might need these safety nets, refinancing your federal loans may not be worth it.

How Student Loan Debt Affects Mortgage Refinancing

Your student loan debt directly impacts your ability to refinance your mortgage. Mortgage lenders evaluate your debt-to-income ratio (DTI) – the percentage of your gross monthly income that goes toward debt payments. Student loan payments count toward this calculation.

According to Freddie Mac guidelines, lenders generally prefer a DTI ratio below 45%, though some programs allow higher ratios with compensating factors. If your student loan payments push your DTI too high, you may struggle to qualify for a mortgage refinance or may receive a higher interest rate.

This is where refinancing your student loans strategically can help. By securing a lower interest rate or extending your loan term, you can reduce your monthly student loan payment, which lowers your DTI and potentially qualifies you for better mortgage terms.

How to Refinance Your Student Loans: Step by Step

1. Gather your current loan information: List all your student loans, including the lender, balance, interest rate, monthly payment, and whether each is a federal loan or private loan.
2. Check your credit score: Most student loan refinance lenders require a credit score of at least 650 to 680, though the best rates typically go to borrowers with scores above 750. You can check your score for free through many credit card issuers or through AnnualCreditReport.com.
3. Compare multiple lenders: Get quotes from at least three to five lenders. Many offer prequalification with a soft credit pull that will not affect your score. Compare the interest rate, loan term options, fees, and borrower protections each lender offers.
4. Choose between fixed rate and variable rate: A fixed rate stays the same for the life of the loan, offering predictability. A variable rate may start lower but can increase over time based on market conditions. If you are planning to pay off the loan quickly, a variable rate might save money. For longer loan terms, a fixed rate provides stability.
5. Submit your application: Once you choose a lender, you will complete a full application. This typically requires proof of income, employment verification, and a hard credit inquiry.
6. Review and sign your new loan agreement: Carefully review the terms before signing. Your new lender will pay off your existing loans directly.

How to Refinance Student Loans Without a Cosigner

Many borrowers wonder if they can refinance student loans without a cosigner. The answer is yes, provided you have sufficient income and a strong credit score. Lenders evaluate your application based on your individual financial profile.

If your credit score or income is not strong enough to qualify on your own, adding a cosigner can help. A cosigner with good credit essentially agrees to take responsibility for the loan if you cannot pay. This reduces the lender’s risk and can help you qualify for a lower interest rate. However, remember that your cosigner is legally responsible for the debt, so this is a serious commitment for both parties.

Risks and Considerations

Refinancing student loans is not always the right move. Consider these important factors before proceeding:

• Loss of federal protections: As noted above, refinancing federal student loans into a private loan eliminates income-driven repayment, forgiveness programs, and federal forbearance options.
• Extending your loan term increases total interest: While a longer loan term can lower your monthly payment, you may pay significantly more in total interest over the life of the loan. This is similar to resetting a 30-year mortgage clock when you refinance your home.
• Credit score impact: Each formal refinance application triggers a hard credit inquiry. Multiple hard inquiries in a short period can temporarily lower your credit score. However, most credit scoring models treat multiple student loan inquiries within a 14 to 45 day window as a single inquiry.
• Fees and costs: While many student loan refinance lenders charge no origination fees, some do. Ask about any application fees, late payment fees, or prepayment penalties before committing.
• Variable rate risk: If you choose a variable rate loan, your payments could increase significantly if interest rates rise.
• Timing with mortgage applications: If you are planning to refinance your mortgage soon, be cautious about taking on a new student loan refinance simultaneously. The hard inquiry and the new account could temporarily affect your credit profile. According to CFPB guidance, consumers should be strategic about the timing of credit applications.

According to CFPB complaint data from 2024, applying for a mortgage or refinancing an existing mortgage was a top complaint category across many lenders. For instance, 28% of Rocket Mortgage’s 339 complaints involved the application and refinancing process. This underscores the importance of thorough preparation and documentation when applying for any type of refinance.

The Difference Between Refinancing and Consolidation

These two terms are often confused but refer to different processes:

• Student loan refinancing: A private lender issues a new private loan to replace your existing federal and private student loans. You may get a lower interest rate based on your creditworthiness. You lose federal loan benefits.
• Student loan consolidation: The federal government’s Direct Consolidation Loan program combines multiple federal loans into a single federal loan. Your new rate is the weighted average of your existing rates. You keep federal protections but do not save on interest.

If your goal is to lower your interest rate, refinancing is the path to consider. If your goal is to simplify payments while keeping federal benefits, consolidation may be more appropriate.

Frequently Asked Questions

Is refinancing my student loans worth it?

It depends on your specific situation. If you have a strong credit score, stable income, and are not relying on federal loan protections like PSLF or income-driven repayment, refinancing can save you money through a lower interest rate. Use a student loan refinance calculator to compare your current total costs against a refinanced scenario. If the savings are meaningful and you do not need federal benefits, it is likely worth pursuing.

Does refinancing student loans cost money?

Many private lenders do not charge origination fees or application fees for student loan refinancing. However, you should always read the fine print. Some lenders may charge late payment fees or have other costs. Unlike mortgage refinancing, student loan refinancing typically does not involve appraisal fees or title insurance.

Will refinancing student loans hurt my credit?

In the short term, a hard credit inquiry from the application can cause a small, temporary dip in your credit score – typically 5 to 10 points. However, over time, consistently making on-time payments on your new loan can help build your credit. If you are rate-shopping, try to submit all applications within a 14 to 45 day window so they count as a single inquiry.

Can I refinance parent PLUS loans?

Yes. Several private lenders allow you to refinance parent PLUS loans. Some also allow the student to take over the debt by refinancing the parent PLUS loan into their own name. This can be a helpful strategy for families looking to transfer repayment responsibility.

Should I refinance student loans before or after refinancing my mortgage?

Generally, it makes sense to evaluate both decisions together. Lowering your student loan payment can improve your DTI for a mortgage refinance. However, applying for a new student loan refinance right before a mortgage application could temporarily affect your credit.
