The previous advice is your first step, talk with a loan officer and get pre-approved and find out what needs to be done to repair your credit.
You mentioned that you want to use your VA loan to purchase and that the house is a manufactured home. I checked the MLS for homes sold on Brownlee (not sure which one was yours) but most are older manufactureds. VA will not approve a loan on a manufactured home older than 1979, so that could be a problem using VA. Remember ... not only you have to qualify for a VA loan, but also the property.
I would be glad to give you some names of loan officers in the area if would like.
I hope this helps and thank you for serving our country!
