Is my security deposit too high?

[Morgan Ward]

Hi I own a duplex in Baltimore city and I'm wondering if my security deposit is too high? I feel like I haven't been getting enough hits on the listing in the past month. I've sent a couple applications but no one has filled them out. The security deposit is 2 months rent not 1. I've listed it on Zillow and a couple other places. It's my first rental and I'm living in the other unit, I guess I'm just wondering if 2 months deposit is too high for the area?
