Flex is a financial technology app designed to give renters breathing room by allowing them to split their monthly rent into smaller, more manageable payments. Instead of depleting a bank account on the 1st of the month, a user pays a portion of their rent upfront, and Flex pays the property management company the full rent amount on time. The renter then pays Flex back for the second half later in the month when their next paycheck arrives. Operating as a line of credit rather than a traditional payday loan, Flex works seamlessly whether a renter pays through a property portal or directly to a landlord.
