If you selected the Flex provided virtual card as your payment method during sign up, here's everything you need to know — how to pay rent, what to expect after, and answers to common questions.

How it works

2. Log in to your rent portal and add the Flex provided virtual card as a payment method
3. Use it to submit your rent payment in the portal
4. Once your payment goes through, Flex automatically charges your 1st payment amount
5. Your 2nd payment will be charged on the date you selected during onboarding

Frequently asked questions

Where do I find my card details?
Your card number, expiration date, and CVC are visible right on your home screen in the Flex app.

Do I need to do anything before using the card?
No, your card is ready to use as soon as you see the details on your home screen. Just add it to your rent portal and submit your rent.

Before you submit rent: make sure you have enough funds available on your personal card for your 1st Flex payment. Flex charges your 1st payment automatically as soon as your rent settles.

How do I know if my rent portal accepts virtual cards?
Most rent portals accept virtual cards. Keep in mind that some portals charge a card processing fee when you pay by virtual card — this fee is charged by your portal, not Flex, and is typically a percentage of your rent. If you're not sure whether your portal charges a fee, check with your property manager.

When do I need to submit rent?
The rent window opens 5 days before the end of the month and closes on the 5th at 9 PM ET. You'll need to submit your rent in your portal before then. Please note, you are responsible for submitting rent in accordance with your property’s due date to avoid potential late fees from your property.

What happens after I pay rent with the card?
Once your rent payment settles, Flex automatically charges your 1st payment to your personal card — you'll get a notification when this happens. Your 1st Flex payment is charged after your rent goes through. No action needed on your end.

I got an alert saying my rent amount doesn't match — what do I do?
If the amount charged at your portal is significantly different from your estimated rent, your payment may be paused and you'll see a yellow alert on your home screen in the Flex app. Here's what to do:

1. Tap "Update" on the alert
2. Check the amounts shown — your current estimate and the new amount from your portal
3. If the new amount looks right, tap "Confirm"
4. If you need to update it, tap "Edit rent amount," enter the correct total, and tap "Continue"
5. Go back to your rent portal and retry your rent payment

I got an alert about my 1st payment failing — what do I do?
After you submit rent, Flex charges your 1st payment automatically. If there's an issue, you'll see an alert on your home screen:

• Not enough funds: Add funds to your linked card (or tap "Change card" to switch to a card with enough funds available), then return to your rent portal and retry your rent payment using your Flex provided virtual card details
• Card declined: Tap "Change card" in the alert, update your card in Settings, then return to your rent portal and retry your rent payment using your Flex provided virtual card details

You'll need to resolve the issue before the rent window closes at 9 PM ET on the 5th. If it isn't resolved in time, you'll need to pay rent directly to your property this month.

Can I switch to a Flex-provided bank account instead?
Yes, you can switch at any time from:

• Your home screen — tap "Switch to bank account"
• Settings → Rent and payments

If you've already submitted rent using the Flex provided virtual card this month, wait until after your 1st payment is collected before switching.

My card isn't working in my portal — what should I do?
Double-check that you've entered the card number, expiration date, and CVC exactly as they appear in the Flex app. If you're still running into trouble, contact Flex support and we'll work to help you identify the problem.
