Here’s how Cozy Express Payouts works:• $2.99 per month per unit• You can enable Express Payouts for any of your units, or all of them• No limits on rent amounts• No limits on number of transactions per unit• If your tenant pays with a card, we won’t charge you for Express Payouts because card payments can be processed faster (and your tenant pays 2.75% to use a card).So that’s it!

The trick is, as you have found out, is getting financing when you own most or all the units.
