That question is difficult because the down payment requirement depends on loan type....typically, you can expect 3.5% for an FHA loan, 5% for a conventional loan, 0% for a VA loan, 0% for any USDA eligible homes with a USDA loan, $100 for an eligible HUD foreclosed property.....
You can see the variances. I recommend you find a local lender to discuss your financial situation and obtain a pre-approval. If you qualify for an FHA loan, you should be good to go to locate a real estate agent and start discussing homes in your price range. An FHA approval is probably where you want to start unless you are eligible for a VA loan. The other loans I discussed (HUD $100 down program & USDA) are possible, but if you just focus on these, you may never find what you need or want.
Hope this helps.
