The cost of being a realtor is not only the class, it's the test and license, joining a brokerage (they charge), joining the board of Realtors, and gaining access to the MLS. 

Any idea on cost comparison or up charge for the service?

I charge for them, because so many of the deals don't pan out.I charge my time plus scope of work, usually works out to be about $275-$500 depending on size of property and how large it is. 

Aside from the very legitimate legal complications to work out.

They say that a landlord may not charge a late fee unless the resident is more than 10 days late on their rent. 

I actually prefer to leave them as the titled owner because there are no property taxes as government entities cannot be charged taxes.

There is not enough info here to know if you have a legitimate out of the contract.

Each time we serve a legal notice, we charge an additional twenty dollars ($20.00) posting fee.If you do not follow the terms of the “Notice to Pay Rent or Quit” we may then begin eviction proceedings against you and you will be charged with the crime of “Unlawful Detainer” if a judge upholds our claim.The amount of rent now due, as of today’s date _________________, is as follows:Current Month Late Fee_______________Current Month Rent_______________TOTAL DUE_______________Time is of the essence.  

Of that $22.25 is the basic charge.

@Anthony Capaldi  Is he charging you 15% interest rate?
