With a middle score of 519, would I be able to qualify for a mortgage to buy ?

Go to Wells Fargo retail and see if they can assist you. Wells Fargo has an FHA program for 500 credit scores and up with 10% down. Obviously there are other factors and the reasons for the low score may be an issue, but that's where I would recommended you start.

My advise would be to have someone analyze your credit and see what can be done to raise your scores whice will give you more options. When we pull credit reports we have the abillty to see if there is anything that can be done to raise your fico scores. If you would like any more info contatct us jafonso@azhomerates.com.
