Don't hold out for "Rent to Own" Properties: It may seem like a good idea at first, but there is much more to consider.
If you are dedicated to the idea of buying your own home, you can create your own savings plan to save up enough money for a down payment. And when you have saved up enough for a down payment, if that takes a year or two or more, YOU get to decide on the price you're willing to pay for the house at that time based on current market conditions. You won't be locked in to a price that may be a lot higher than what the house is worth in the future.
With Rent To Own, even if you can find such properties, you'll be locked in both to the house and to the price, even if it takes you 3 years to save enough through the forced savings of the rent payments. What happens if three years from now your life situation has changed? Maybe you need a bigger/smaller home. Maybe your employment has relocated. Maybe your credit or income is insufficient to qualify for a mortgage loan.
Find a way to save up on your own; not with Rent To Own. Rent To Own is a better deal for the Seller than it would ever be for a potential Buyer, because he gets to lock in a purchase price and a buyer today for a future sale.
Sit down with a local Mortgage Banker and get yourself prequalified, too. You may find you're better qualified than you think you are, and, if you're not, at least you'll know how much loan your income and credit qualify you for, and how much you have to save towards down payment and closing costs.
