Land Contracts are harder to find but possible. You should contact an experienced Realtor to help you locate the right property and terms. If you want someone to work hard for you, hire them as your Buyer's Agent.
You will likely need at least 10-15% for down payment since Sellers still have to pay closings costs with a Land Contract. The shorter term you require the better in the Seller's eyes.
