As an experienced real estate agent and previous mortgage lender, I can answer any questions you might have.
What you are looking for is a lease to own list of properties. Investors will buy homes for qualified buyers and allow you lease to own.
Here is an agent I know who explains it very well in her blog
I might be able to refer you to an agent in Billings that can provide you with a list.
Are you already working with a realtor? And would you be willing to get pre-qualified by a lender?
