Usually scores below 600 have a tough time getting an automated approval unless there are some significant compensating factors. Compensating factors such as a significant down payment (10% or more), a low debt to income ratio (usually below 30%), and excessive reserves (usually 6-12+ months). Your debt to income ratio is low, but it's around 33%, so in my opinion that might not cut the mustard regarding getting an automated underwriting approval or not. How much are you putting down? If it's 10% or more, and because you have a low debt to income ratio, then that would improve your chances of getting the automated underwriting approval. If you can wait, and it appears you can, I'd wait until the collection comes off and your scores update... the FHA pre-approval process would require less paperwork if you are able to get an automated underwriting approval.
