I had a co-worker here in GA who obtained her home with NACA. She had a BK due to foreclosure in 2004/2005. I believe her process with NACA was over 3-6 months and she was financed for a 190K home. She was able to use combo of 401K and builder incentives for downpayment, I think. She had a great relationship with her counselor who she said always seemed to be on the ball and timely with confirmation of receipt for documents she had to fax in.
However, she referred another co-worker and gave her the counselor's contact info. Well, the counselor said she didn't have the availability to take another applicant and passed the referral to a different counselor. This person was extremely slow to respond to emails and ultimately the referred person became discouraged.
Nonetheless, the NACA placed homeowner has nothing but great things to say about NACA and she highly recommends them to anyone even remotely interested in homeownership.
