Unfortunately, your situation is not uncommon. So many have gone through the same distress you describe. You can be sure the rental market recognizes your situation and has accommodated the need.
Here is what you need to prepare.
#1. Document you have been a home owner and know how to care for a single family home.
#2. Explain how your hardship was created.
#3. Describe how your situation is different
#4. Reveal how the cause of previous difficulty no longer exists.
#5. Have sufficient cash on hand to make security deposit and pay professional fees.
#6. Work with a real estate professional who can identify those home owners and investors with a home to rent that meets your needs and understands your situation.(Don't under estimate the importance of working with a professional)
You will find your situation is not dire at all.
Best of success to you,
