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.
Clear, upfront pricing
No hidden fees or penalties.
No balance growth
The amount you owe doesn’t increase over time.
On-time rent reporting included
So paying rent can help build your credit history.

Frequently asked questions

Do I have to use Flex every month?

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.

Why does Flex use flat pricing?

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.

Does Flex help build credit?

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.

Can using Flex hurt my credit?

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

What happens if something goes wrong with my payment?

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.

Can I pay with a credit card?

Yes. You can use a credit card to make payments with Flex. An additional 2.5% processing fee applies to cover card processing costs.
