As Mack pointed out, and the many professionals who will respond to your question will confirm, for most entering into a lease purchase will also result in 'throwing your money away."
There are NO shortcuts to establishing a qualifying credit history. The temptation to take a credit repair/recovery short cut will also result in "throwing your money away."
Here is a great option you should consider. Contact a local lender (NOT at too big to fail) who has a historic record of investing in your community through small business loans, home loans and refinances. These are "A" and "B" graded lenders. The 'Too Big To Fails" are all "F" rated, justifiably.
Simply enter our city or zip code and make an appointment with the lender(s) that appeal to you.
Share with them your desire to purchase and your need for their guidance to get you fully qualified for a home mortgage. They will guide you through the best sequence of steps to reduce your debt, manage your budget, establish saving and create the needed down payment. There will be real discipline required. But, very quickly you will begin to see the magic of fiscal responsibility and the security that follows. It's common sense that is very uncommon.
Now call, YOU WILL BE GLAD YOU DID!
