Yes! You can upgrade to Pro at any time. If you downgrade, you'll keep Pro features until the end of your billing period.
A property is a single address with one or more units. A duplex with 2 units counts as 1 property. A 10-unit building counts as 1 property.
A workflow is a reusable template for automated communication (e.g., "Move-In Workflow"). You can run the same workflow for unlimited tenants - only the template counts toward your limit.
The Free plan lets you try all core features with 1 property. When you're ready for more, upgrade to Pro - you can cancel anytime within the first 14 days for a full refund.
