HUD is issuing this interpretive rule to clarify the scope of the provision in the National Housing Act that prohibits certain sources of a homebuyer's funds for the required minimum cash investment for single family mortgages to be insured by the Federal Housing Administration (FHA). Uncertainty has arisen as to the effect of this provision on State and local governments and their agencies' and instrumentalities' homeownership programs that provide funds for the minimum cash investment. This rule provides HUD's interpretation that this statutory provision does not remove the availability of FHA insurance for use in conjunction with State and local government programs that provide funds toward the required minimum cash investment. Although interpretive rules are exempt from public comment under the Administrative Procedure Act, HUD nevertheless invites public comment on the interpretation provided in this rule.
