The Missouri Application For Registration of Single Family Mortgage Revenue Bonds is a legal document used by the state of Missouri to issue mortgage revenue bonds for the purpose of financing single family housing. The bonds are issued by the Missouri Housing Development Commission (MDC) and are secured by a mortgage lien on the property being financed. There are two types of Missouri Application For Registration of Single Family Mortgage Revenue Bonds: taxable and tax-exempt. Taxable bonds are issued to finance projects that provide housing for people who are below the median income level and are subject to federal income tax. Tax-exempt bonds are issued to finance projects that provide housing for people who are above the median income level and are exempt from federal income tax. Both types of bonds are subject to MDC approval and require registration with the Missouri Secretary of State.
