The short answer
Yardi Breeze lists residential pricing at $1 per unit per month with a $100 monthly minimum, on an annual agreement. Breeze Premier keeps the $1 rate but raises the minimum to $400. That makes Breeze cheap for a manager with 100 to 200 units, and expensive per door for a landlord with 12. A 12 unit owner pays the $100 minimum, which is $8.33 per unit, and signs for a year.
Letting charges $59 per month for up to 25 units, billed monthly or yearly, and you can stop at the end of any billing period. If you need tenants to pay rent online, tenant screening and RentCafe listings in one system, Breeze includes those and Letting does not. That is the line to decide on.
