There are a number of value added services that Propertyware provides. The most basic component is based on the number of units. I think they cut out the lower numbers that they had. The lowest now is 1-50 units for $75/ mo. As the number of units go up, the monthly price also goes up.
The other component consists of a number of optional value added services, such as online storage ( first 500 meg is free ), integrated web hosting, marketing, etc. each has their pricing. There is some discount for annual payment in advance.
My guess is, if the sales person is unclear of your specific needs, she would have some difficulty providing you with a quote.
