Tennessee Housing Development Agency - As enacted, increases, from $4 billion to $5 billion, the maximum aggregate principal amount for which the agency may issue bonds and notes at any one time. - Amends TCA Section 13-23-121.

SB 129 increases the Tennessee Housing Development Agency's (THDA) maximum bond limit from $4 billion to $6 billion. This change allows THDA to issue more bonds to fund below-market interest rate loans for low- and moderate-income Tennesseans. The bill directly affects THDA's ability to provide housing assistance programs, addressing rising demand since 2008. It amends Tennessee Code Annotated Section 13-23-121(a) to update the financial cap.
