The short answer is no. Except if you are paying cash, but since you are bringing credit into the question I must assume that you are wanting to take out a mortgage. Qualifying for a HUD repo. is no different than qualifying for any other type of home except that you will probably need a rehabilitation loan for repairs.
With the current economy the only way to obtain any house without a great credit score is to pay cash! HUD houses are generally lower price and some are quite affordable.
Yes I think you can get a HUD home with bad credit as long as you meet the required demands ent in place to qualify. To obtain more information to get the process started you need to contact the Hud office in your area. Once they get your information they will have a better understanding of what you need
It is possible to acquire a home through HUD with bad credit however to better your changes it is recommended that you have a down payment available to show that you would be able to make the payments. I recommend talking with a Realtor in person about your situation.
