Generally not with conventional financing, but lots of ways with creative financing.
With conventional financing, if you're a veteran, you can get a 100% VA loan. You can get a 96.5% FHA loan. And some states have some special programs as well. Check with a good mortgage broker to find out what you might qualify for, and what programs are open to you.
With creative financing, you often can buy with no down payment. For example, look into "subject tos." Or, for no down payment now, look into lease-options.
Hope that helps.
