Assuming you have some credit challenges and/or need extra time for a down payment, renting to own can be a great idea. There are many different ways to structure them, but the process is not difficult. I wouldn't necessarily advise locking in the price upfront because values will likely continue to decline. You also have to decide how much, if any, of the rental payments will be credited back to you in the form of a down payment. You will also need to determine the length of the option period. I can definitely assist you with this process.
