1. I qualified some folks that owned a mobile home. It was not considered a home and they qualified for 1st time buyer, even though they had the mobile home.
2. Not sure if it hits you as hard as losing a home, but it will still show up as a repo, which will prevent you from qualifying. A - having the repo hurts your credit. B - if you have a "remaining balance" after the repo, in other words if you owe $10K, they sell it for $4K, then you will still owe $6K to them on top of having the repo on your credit. So both the repo as well as the amount owed will affect your credit.
As much as losing a home? No. But it will still prevent you from buying a home anytime soon.
