First Time Selling a Rental

[Corbin H.]

Hello, This is my first time selling a property. I purchased a home in Tacoma, Washington very low in 2013. I am attempting to sell the home now with an agent for a substantial markup. My tenant wants to make an offer on the home 2 months from now. I spoke with my listing agent about holding off on the listing until June. I'm getting some of the red flags I've read about in the BiggerPocket books about the agent. Being rushed to complete documents, confusing my property with another, etc. I just don't have enough experience to know if I'm getting the best deal or being over cautious. 

1. Does a listing agent fee of 4% and buying agent fee of 2.5% sound correct for this area?

2. Can I legally install the keybox as well as show the home while I have a tenant inside the property or do I have to wait for them to vacate? 

Any advice would be appreciated.
