Missouri Housing Development Commission (MHDC) has lowered the interest rates on mortgages offered under its first-time homebuyer program. A 3.50 percent 30-year fixed rate mortgage is available to homebuyers not needing assistance with down payment and/or closing costs, while a 4.0 percent 30-year fixed rate mortgage is available to those buyers who do take advantage of cash assistance. These rates are the lowest ever offered by MHDC.
