VA and USDA are the last 2 programs standing that still offer 100% financing. They have specific qualifying guidelines so not everyone can take advantage of them. Some states offer 100% financing. Maryland has a CDA program that offers 100% financing. There are property and income restrictions with the program so once again it is not for everyone.
I'm doing my first HUD owned $100/down purchase right now. Pretty good deal too. HUD publishes a list of foreclosed properties that are eligible for the $100/down program.
Conventional still offers 3-5% down but it is a bear to qualify for. 10% down is much easier.
While I don't think a lot of programs from 2006 should have existed, there are quite a few that have been eliminated that I miss dearly right now.
