Best way to find a renter/ service provider

[Carlo D.]

Hi Everyone. New real estate investor here. 

A bit about my background. I am an insurance broker and a hedge fund manager and I am about to close on my first rental condo in NYC.  Since I have two full time businesses, I don't have a ton of extra time left in the day. So my question was what is the best way to find my first renter? Or the best service provider that helps me find a renter? redfin? zillow? my realtor?  

Also, considering joining pro. But I was wondering if there is a difference between Stessa and Rentredi. Are they the same type of platform, or do they work hand in hand? I am seeing some redundancies.  

Thank you in advance!
