Flex gives you the flexibility you need today—without sacrificing tomorrow.

Rent is large, fixed, and due all at once—even though income rarely arrives that way. And it comes due alongside everything else that matters: utilities, transportation, childcare, and healthcare.

Fair by design

No late fees or penalties

Flex doesn’t profit if you fall behind.

No balance growth

The amount you owe doesn’t increase over time.

Clear, upfront pricing

No hidden fees or penalties.

On-time rent reporting included

So paying rent can help build your credit history.

Frequently asked questions

No. Your monthly membership keeps the option to split your rent available every month. You choose when to use Flex based on what works best for you.

Because needing more time shouldn’t cost you more. When you split your rent with Flex, the total cost is clear upfront and stays the same throughout the month. You can make your second payment when it works for you without the price changing. A stable monthly fee also helps you plan for access to Flex for when you need it and lets you compare Flex to alternatives such as late fees and bank overdraft charges that are often charged in dollars, not percentages.

Flex reports on-time rent payments to TransUnion at no additional cost, which can help build your credit history over time. You can decide to turn off this feature if you choose.

Flex only reports positive activity towards your credit profile. It’s designed to help you stay current on rent—not create new credit problems.

If something doesn’t go as planned, our support team works with you to help make it right. We’re here to help you stay on track, not to penalize you.
