Rent to Income ratio receiving negative reactions

[Rory Fowler]

I have a unit in a duplex posted for rent. The previous owners had some bad experiences with tenants in this duplex but it is in a great neighborhood (I live in this neighborhood. It's positioned in great suburb with a top school system, easy access to major corridors for the metro area. Newly remodeled in March 2017 with great interior upgrades - granite, cabinets, appliances, etc. The previous owners were terrible at screening and got burned out. Their last tenant before I purchased asked to leave because she couldn't afford to stay. So I have posted it today for $900/month with a requirement of $3,000 gross income. I am getting a ton of negative unsolicited feedback about this. I always post with the 3x income requirement, but decided to round it up another $300 on this one to trim down the borderline income qualified applicants. I've filled the other side with a great tenant who easily meets this requirement (didn't have to advertise that side). Am I out of line on this? This duplex should be attracting a high end tenant than what it has historically had. . How do you attract/"screen up" to better tenants?
