Actually, after I answered this, I saw a Mortgagee letter from HUD dated 5/11 in which it seems that state and local governments and qualified non profits will be permitted to "loan" first time home buyers their expected tax credit, up to the amount of their down payment + closing costs for the home. There's a fee, of course, but I suspect this is the next role for Nehemiah. The letter didn't say Nehemiah - but it makes sense they will fill this bill since they're fundraising services were knocked out of existenace last fall.
"Colorado" - is this what you were referring to? I've not seen much press on this and even the Nehemiah site didn't have information on it yet. So, if you're looking for someone that knows the ins and outs of THIS you won't find them, it's never existed before.
