Today, companies with many structures use the word turnkey to describe their services. 

What is the cost of the service?

However, I read some bad reviews about them. 10% service fee from landlord, plus 8% from tenants.

The other option is to file with the RTDRS (Residential Tenancy Dispute Resolution Service). 

After years of self-managing our single-family rentals, we decided to hire a property manager to provide full service management.

He works with us often here in Chicago, but can service loans across the country!

When evaluating a property management company, it's important to look beyond just the management fee and consider the full scope of services and costs involved.For example, at our company, we charge a 10% monthly management fee, a $250 lease renewal fee (unless it’s a takeover tenant, which requires additional effort to establish a strong relationship - because usually people are changing pm companies for a reason), and the first month’s rent as a leasing fee.

any lender wants to know how you plan to service the debt.

It's important to keep in mind that everyone you hire is providing you a service - no one is guaranteeing you any outcome.

There are best practices on certain items that provides a guidelines.Commissions are always negotiable like any other services, you can shop around for the best value for money.All depends on the risks that you are willing to take.
