Our Take

ISL refinance loans are best for creditworthy borrowers seeking competitive fixed rates, no fees, and the ability to prequalify through a soft credit check. They also provide flexible repayment terms and a cosigner release after 24 on-time payments. However, eligibility is limited as borrowers in Connecticut, Maine, and Puerto Rico are not eligible to apply.

Iowa Student Loan Liquidity Corporation (ISL) is a nonprofit education lender founded in 1979 and headquartered in West Des Moines, Iowa.

Through its Reset Loans, ISL offers nationwide access to its private student loans and refinancing products, which include parent loans and in-school refinancing.

Unlike some other lenders, ISL offers a loan product specifically for those needing to refinance while in-school. However, those using that option may have slightly higher rates and a lower maximum loan refinance amount of $200,000.

Even if ISL has competitive rates, compare multiple refinance lenders before committing to a loan. Prequalifying and comparing lenders is the best way to ensure you’re getting the lowest possible rate and most affordable repayment plan for your budget.

  1. Check your eligibility.

    Iowa Student Loans, offered by Iowa Student Loan Liquidity Corporation, evaluates applicants based on credit history, income stability and overall ability to repay. Borrowers can typically apply on their own or with a qualified co-signer.

  2. Prequalify to explore your rate options.

    Start with the lender’s online pre-qualification process to see estimated rates and repayment terms. This step generally uses a soft credit inquiry, allowing you to compare potential offers without affecting your credit score.

  3. Choose your repayment term.

    If you qualify, you’ll be able to review available fixed or variable rate options and select a repayment term that fits your monthly budget and long-term repayment goals.

  4. Complete the full application.

    Move forward with a formal application by submitting documentation such as proof of income, identity verification and current loan statements. A hard credit check is typically performed during underwriting.

  5. Finalize the refinance and transition your loans.

    Once approved, review and sign your loan agreement. Iowa Student Loans will then coordinate payoff with your existing lenders, after which you’ll begin making payments under your new refinance terms.

As you review your offer, it may also be helpful to consider whether applying with a co-signer could improve your rate or approval odds, particularly if your credit profile or income is still developing.
