strata / property management business

[Manna Sivia]

Hello everyone,

I am thinking to start a strata / property management company in BC Canada.

Can anyone please give some basic information about this.

main question is 

How much is the  ravenue of a average ccompany ??

According to me if strata / property management company manages 1000 doors and charge 10% of rent means $150 of $1500 rent that makes $150 * 1000 = $150,000

Thats all a company makes in year or is there some bigger numbers.

Replies will be appreciated.

thanks.
