Assuming you are waiting to go FHA, at least based on your credit score. That said for FHA you need 3.5% for the downpayment. I keep seeing some FHA lenders doing a zero downpayment but not sure if the qualifing score is higher or not. Best bet is to shop around and see if a Loan Officer can tell you if they can help or not.
Judging from what you listed you have a decent employment record and the score for FHA.
Good luck to you!
You can try USDA if your state has it. It requires $0 percent down. The only thing is you have to buy USDA approved homes within a ceratian area. Rual areas. This can be a drive to work and back depending on where you live. We are looking at this option right now. I'm trying to remove the "disputes" on my credit report. You need a min score of 640 to qualify. Good Luck!
