Determining how to lease with the First Property

[Cobe Mouton]

Currently myself and my wife are trying to decide between hiring a broker to least our 1st house and losing the security deposit upfront. From fees using the broker and coming out of our pocket when the tenant leaves and paying them the deposit back originally if the property is well maintained of course. The other option is listing the property ourselves with not that much exposure other than your typical sites as Truila, Zillow etc ourselves and making sure we still have the security deposit sitting in an account and not be touch. 

What is the benefit of using a broker to list the property if at the end you come out pocket paying the security deposit? The contract I can buy for $100 dollars based on the state and using a rent pay website to collect funds and do the background check for tenants within that site.

Am I missing something?
