Maria got it almost right, the website you want is WWW.THECHA.ORG.
But don't hold your breath, 'section 8', now called HCV or home-choice voucher,
doesn't appear to be a viable solution. The waiting list is closed, has been for

If you're looking to buy a home, call or visit the FHA website to locate a local lender
familiar with them. The HOMEPATH and HOMEPATH RENOVATION mortgages sound
pretty good.. interview realtors, they can tell you about various programs.
