How much you need for a down payment in the Boise area, known locally as the Treasure Valley, depends on the loan program you qualify for, and there is a wide spread. The table below lays out the common programs; your lender confirms which ones fit your situation and your exact terms.
Down payment by loan program
Typical down payment by loan program
| Loan program | Typical minimum down payment | Notes |
|---|---|---|
| Conventional | As little as 3% | Private mortgage insurance typically applies below 20% down |
| FHA | 3.5% | For eligible borrowers; mortgage insurance is required |
| VA | 0% for eligible buyers | For qualifying veterans and service members |
| USDA | 0% for eligible buyers | For eligible rural areas, subject to income and location limits |
| Idaho Housing DPA | Up to 8% of the sales price | Down payment and closing cost assistance for eligible buyers (idahohousing.com, checked October 6, 2026) |
A worked example
On a $500,000 home, a 20% down payment is $100,000 and a 10% down payment is $50,000. At 3% down, the down payment is $15,000 and the loan amount $485,000. A larger down payment lowers the loan amount, which lowers the monthly payment and can remove private mortgage insurance; a smaller one preserves cash. The right point between them depends on your savings, your monthly budget, and the loan program.
Idaho down payment assistance
Idaho Housing and Finance Association, Idaho Housing, offers down payment and closing cost assistance of up to 8% of the sales price for eligible buyers, along with homebuyer education and approved lenders statewide. Eligibility details, income limits, and the current program terms live on the Idaho Housing website, idahohousing.com, and you should confirm them with an approved lender when you apply.
The real question is the payment
The down payment matters, but the monthly payment decides the budget. We build the full picture, down payment, loan amount, taxes, insurance, and HOA dues, before you shop, and we pick the down payment strategy that fits your savings and your life. The buyer guide walks through the whole process.
Sylvia's Advice
I tell buyers not to aim for 20% down just because it sounds traditional. In the Boise area, many buyers use a smaller down payment and keep cash in reserve, or pair a conventional or FHA loan with Idaho Housing assistance. What matters is that the payment fits comfortably and you are not emptying every account the week after closing. Talk to a lender about which program fits you, then bring me the approval and we will shape the search around the homes your payment supports.
