The renter makes a first payment when rent is due, and Flex pays the property in full and on time. The renter then chooses a date later in the month for the second payment. Flex reviews the renter's financial information to approve a credit line, which determines how the rent is split, and the payment amounts are shown before the renter proceeds.

Does the landlord have to partner with Flex?

No. Flex works directly with many properties and payment portals, but a renter can use it without their building or landlord partnering with Flex. In that case Flex provides a virtual debit card or bank account that is used to pay the rent. Availability is still subject to renter and landlord eligibility.

Paying rent through Flex costs a monthly membership fee of up to $5.99, a 0.5% processing fee, and a split fee of up to 3% on the second payment based on how much is borrowed. Using a credit card adds a 2.5% surcharge. The split fee is not reduced by repaying early.

Does Flex charge late fees?

No. Flex states that it does not charge late fees and that a member's cost is set upfront and does not increase the longer the balance is outstanding.

Payments & rent collection

Flex

Flex splits a renter's monthly rent into two payments. The renter makes a first payment when rent is due and Flex pays the property in full and on time; the renter then picks a date later in the month for the second payment. The same split is offered for mortgage payments and for everyday bills such as car payments, utilities, and phone.

Flex works with properties and payment portals directly, but a renter does not need their landlord to partner with Flex: where there is no integration, Flex issues a virtual debit card or bank account used to pay rent. Approval rests on a review of the renter's financial information, which sets the credit line and the split amount, and the amounts are shown before the renter commits. On-time payments are reported to all three national credit bureaus at no extra cost.

Flexible Finance, Inc. is a financial technology company, not a bank; loans, lines of credit, banking services, and disbursements come from Lead Bank or Column N.A. Brokering is performed by Flexible Finance Brokering, Inc. (NMLS ID #2599800) and servicing and collections by Flexible Finance Servicing, Inc. (NMLS ID #2256673). The company reports 3.5 million renters served since 2019 and support for nearly 2 million households in 2025.

Availability is subject to both renter and landlord eligibility, and the cost is a membership fee plus percentage fees rather than a flat charge, so check the quoted total before pointing residents at it. The site does not describe what happens at the property when a second payment is missed, which is worth asking about.

Best for

Operators who want residents to be able to pay rent in two installments without the property extending the credit, and renters whose pay cycle does not line up with the first of the month. The cost falls on the renter, not the property.
