• if you just had a bankruptcy (because of it you could have a disaster in your credit rating) you need to wait two years in order to get/apply for a va loan.
• wait one year after bankruptcy - if you did not control it; you have been fired or you have any other problem that you could not be controling - this does not mean you have to wait an year in order to get the loan - there are also sub prime lender that are willing to give you the money. This type of bad credit lenders are there in order to make some business and win some money based on the many people having this kind of problems - with bad/poor credit.
• you need to wait an year or two - but in this year you need to show that you have payed your bills and taxes in time in order to show you are a good borrower and you could give back the money in time. 

   Start to repair your credit faster in order to get loans with natural and normal interests - not from bad credit lenders. You may need to monitor your credit score and get some loans you have to pay in time (no late payments) in order to be sure you're not going to have any more problems into the future. It's good to improve your credit score in order not to have problems - because, as I've been saying, it's always easier to get a va home loan when having a good credit score, rather than having a bad credit score. 

   Get new sources of credit in order to improve your credit score. It's better to open some sort of secured credit card in order to improve your credit history - in the case of secured credit cards you are going to have to put some sort of deposit - like up to $1000 on the card. But, beside this you should know a couple of tricks, that you have to use a small sume from the card and then repay the money in order to improve your credit score in time. 

   How you could get a secured credit card? Is this going to help you with your va loan? Sure, you may not get one if you have a bad credit history/rating, so it's better to improve your credit score in order to get it - wait a little before taking the money, it's better and in overall you're not going to spent so much money, you don't have them, think about them. You have that credit score bad for a reason, you had some sort of financial problems, and you may still havem them. Getting a secured credit card is easy, just go to the bank and ask to apply for one, anyone could easily get one of this, if he/she puts money on the card.
