Patricia, any real estate agent can help, if they choose to work in lease-to-own. Some don't include leasing in their general business policy, so just walk-in at a local agency and ask for the broker/manager (yes - we still take walk-ins). They'll know which agent to suggest, based on your needs.
Residential leases are great, because you are typically dealing with an individual landlord, and your specific story on your credit history and your current financial status can more openly be discussed and included in the decision of the landlord to rent to your family, or not. I am finding 1-2 year leases common right now. Many people are in situations that will take longer than 12 months from which to recover. A 2-year residential lease is perfect for financial recovery. I'm also seeing custom short-term leases, for individuals looking for flexibility toward the end of a lease. These are great for people who are looking to time their lease to the estimated completion date of a new home, or for folks who need a little more time in order to allow their current home to sell.
Have a blessed day!
