I have to admit that Don Tepper's explanation on his blog sums it up.
You want to do your research and learn the basics of how a Lease-to-Own works so that when you're looking for people to assist you (like a real estate attorney, mortgage broker, and if you choose to use one ..... a real estate agent) you can ask intelligent and poignant questions. Make sure you work with only those people who have successfully completed one of these transactions so that all your bases are covered.
One key thing to do is to start working on your credit AS SOON AS YOU MOVE INTO THE HOUSE AND START THE LEASE. Too many times, people wait months and months to start improving their credit, then it comes down to the end of the lease option period and they aren't ready to get traditional financing....hence....they wasted their time. Develop a game plan with your credit repair specialist and mortgage person. Don't go out and buy any big ticket items until you have closed on the house.
Best wishes on your search!

It may be best to fix your credit before trying the rent to own. You do not want to get in more trouble by making another mistake.
