IHFA 8% repayable second mortgage — the true cost vs grant alternatives
Idaho's IHFA offers a repayable second mortgage at 8% interest as down payment assistance. It's not a grant. Over the life of the loan, that 8% second can cost a buyer $30K+ in interest. Sometimes a higher first-mortgage rate with a grant alternative is cheaper.
How the IHFA second mortgage really costs
On a $15K second at 8% over 10 years, monthly payment is roughly $182. Total payments: $21,840. Interest paid: $6,840. That's the true cost of using IHFA's repayable DPA — $6,840 in additional interest the buyer pays for the privilege of having $15K at close.
Compare: pulling $15K from a 6% HELOC (10-year payoff at $166/mo) = $19,920 total, $4,920 interest. Same outcome, $1,900 less cost.
FHLB Welcome Home Grant — the better deal when available
Federal Home Loan Bank of Des Moines offers Welcome Home Grant up to $20,000 for income-qualifying Idaho first-time buyers. Forgivable over 5 years if you stay in the home. Functionally free money.
Idaho lenders with FHLB membership can offer this — Cornerstone is one. Application opens annually with allocation that depletes fast.
USDA Section 502 Direct — rural Idaho path
USDA Section 502 Direct offers 1% interest rate for income-eligible rural buyers. Many Idaho areas qualify — Coeur d'Alene metro suburbs, Idaho Falls, Pocatello, most of Eastern Idaho.
Income limit ~80% of area median. Property must be in eligible USDA area. 0% down. 1% rate over 33-year term — dramatically lower lifetime cost than conventional or FHA.
