There is only one kind of good debt: Mortgage at under 4%, like 2.75% 30 year fixed loan that is great debt. Because you can basically put down 20% and leverage the rest from the bank. So you are putting down 200k on a 1,000,000 home so you are basically hoping for long term appreciation of 4-6% on the 800K that is not yours, while living in the house. That is good debt, the rest I don't think is worth considering.
