It's important to remember, especially with marginal credit, that you can probably be approved for a rent = 1/3 of your gross monthly income. So for a home renting at $1400, you would need to prove income of $4200 monthly.
Please feel free to call me if you are still looking for a home to rent. There are quite a few available in your price range of $1400 or less.
All the best,
