Rent Estimate Accuracy of Zillow vs Redfin vs Rent-O-Meter?

[William DeHaan]

I’m having a difficult time trying to figure out the rent value of my 5 bedroom, 3350sf single-family dwelling in Oceanside California. Zillow says $5600 per month, Redfin says $5000 per month, Rent-O-Meter says $4100 - $4500 per month. Which platform generally is more accurate and are there other tools out there for this? 

Thanks very much!
