ISL Online Reviews

Below are 3 samples of ISL customer reviews we found on public forums, included here for their value as unsolicited and uncensored user experiences. Note that these reviews are unverified, may include inaccuracies, and may provide outdated information (about rates, bonus offers, etc.). Some reviews have been edited for length or clarity.

“I have 37K in private loans from postbacc that I have regretfully not even looked into refinancing until now. I was approved through ISL with a fixed rate of 4.75% (worlds away from my current 8.5% with Navient). The finance charge is ~8K, which from what I can tell, is a normal part of this process right? Also, I signed on for the quickest repayment plan, which obviously has the highest monthly payments once residency is over. I won’t be able to afford that, but opted for the plan to get the lowest interest rate, with plans to just refinance again before I get to that full repayment period after residency.”_perestroika on reddit, 11/10/2021

“I was able to go through with a loan refinancing through the company ‘Iowa Student Loan’ and quite literally cut my payments in half. Knocked my interest rates in half as well. For the first time in over 5 years, I can breathe. I’m not going to bed stressed out about how I’m going to pay next month’s bills and therefor was able to get some time to better my mental health, job hunt a bit, and now work for a company that I really enjoy the work I do and, while I still don’t make GREAT pay, pays me enough to live comfortably. Sorry for the run-on sentence there, but I’m just over the moon with joy to type this.”eccles714 on reddit, 6/5/2020

“I’ve been in school on and off for awhile (stay at home Mom of two young children) and I’ve always dealt with Iowa student loan liquidity. Now all of a sudden I start getting info from [a different, for-profit loan servicer] and my monthly payments almost double. Doesn’t seem right!”Jenn2182 on, 8/22/2012

As part of their mission, the CFPB allows consumers to log official complaints. These complaints are publicly available on the CFPB official website.

Complaint 4865924

“On XX/XX/2019 I enrolled at digitalcraft bootcamp, skills fund advertised student loans. I was under the impression i applied for the XXXX XXXX XXXX student loan. According to credit agreement, the funds will not be disbursed unless the school is in compliance with its funding obligation. The school certification would determine if I am eligible for the loan and for how much. Skills fund recently stated they only do unsecured consumer debt loans, not student loans for bootcamps, and I do not generate 1098 forms. Myself I did not receive a student loan despite being approved by digitalcraft and promoted by skills fund. On my aspire account within my forbearance letter my loan is referred to as XXXX XXXX XXXX XXXX XXXX ( XXXX ) and/or private student loan ( s ). When I called Aspire customer service they stated it is not a student loan and this is a consumer loan despite it showing as an education loan on my credit report and no 1098 forms are listed in the tax information section.”

Complaint 4642587

“Facts : I XXXX XXXX am a consumer as defined by 15 USC 1692a ( 3 ). ” ASPIRE aka ISL/XXXX ” is a creditor as defined by 15 USC 1692a ( 4 ). ” ASPIRE aka ISL/XXXX ” alleges that I XXXX XXXX owe them a debt as defined by 15 USC 1692a ( 5 ). ” ASPIRE aka ISL/XXXX ” is a corporation whose residence is in the state of IOWA. XXXX XXXX is a natural person whose residence is in the state of CONNECTICUT. We are still within the statute of limitations for this case as the company in question is still violating my rights as a consumer willfully after being asked to stop since XXXX of XXXX and XXXX of XXXX. ” ASPIRE aka ISL/XXXX ” has failed to supply any record of payment by me validating these claims of late payments from XXXX. As you can see my account was closed because of SUCCESSFUL ON TIME PAYMENTS for the duration of the loan and relationship with ASPIRE aka ISL/XXXX. ALLEGATIONS/COMPLAINT : – ” ASPIRE aka ISL/XXXX ” in an attempt to collect on this alleged debt has violated 15 USC 1692 ( b ) by communicating with third parties about this alleged debt without expressed consent of myself the consumer. They have shared this debt with numerous credit data furnishers and sold this alleged debt to a data furnisher without verifying its validity after I the consumer notified them in writing that this alleged debt was not mine and I was taking steps to investigate it personally. – ” ASPIRE aka ISL/XXXX ” in an attempt to collect on this debt has sent letters threatening to ruin my reputation by sharing my private information violating 15 USC 1692d ( 1 ). – ” ASPIRE aka ISL/XXXX ” in concert with the consumer data furnishers both have caused my phone to ring repeatedly at work and on my personal phone even after I asked them to stop violating 15 USC 1692d ( 5 ) and 15 USC 1692e ( 8 ) by threatening to communicate to other persons and credit data furnishers information which I believe to be false.”

Complaint 4380066

“This student loan was in a repayment plan up until XX/XX/XXXX when I was told that the remaining debt was considered satisfied for less than the full balance following the plan completion. My parents received collection letters beginning in XXXX for an outstanding balance but I was never directly contacted. When I contacted Aspire Servicing Center about an outstanding balance of over {$1100.00} spanning 3 accounts in XX/XX/XXXX, I spoke with a representative and informed them that I had already paid off the balance following a repayment plan ending in XX/XX/XXXX. At that time, Aspire informed me that their legal team would investigate the account. Upon completion of the investigation, they informed me they would cease collection activities. I did not pay this account off in XX/XX/XXXX since it was already paid off as of XX/XX/XXXX, so the credit reporting incorrectly reflects the account as in a collection status from XX/XX/XXXX through XX/XX/XXXX.”

ISL Lawsuits

While ISL has faced charges from the U.S. Department of Education (for which the lender was required to pay $2.4 million) and 31 complaints to the Iowa Consumer Protection Division of the attorney general’s office, the lender has not face major litigation in the last decade.[1][2]

Iowa Student Loan Liquidity Corporation (ISLLC), ISL’s parent company, was heavily criticized for its own legal action in the early days of the COVID-19 pandemic when ISLLC initiated over a dozen lawsuits against indebted student borrowers. By early April, ISLLC agreed to cease new lawsuits and “retroactively dismiss any suits filed after the declaration was issued.”[3]

Note that while this information is updated regularly, ongoing legal action is subject to change.
