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 $29 per month billed yearly, and you can stop at the end of any billing period. On yearly billing Letting also undercuts Breeze at 50 and 150 units ($94 against $100 and $150). 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.
