Idaho Housing, Approved Lender

Cornerstone is an Idaho Housing, approved lender, licensed statewide from Ada and Canyon County up to Kootenai County. We originate the Finally Home! first mortgage and its down payment second directly.

Honest Advice

Real Boise and Nampa numbers, no salesy script. We will tell you when Idaho Housing's repayable 8% second costs more than a plain Conventional 97, because for some files it does.

First-time buyer in Meridian, self-employed in Coeur d'Alene, jumbo near Sun Valley, Boise rental investor, or a move-up seller in Eagle: we cover the full toolbox.

โ†ป

Mike and his seasoned Idaho loan officers handle every file directly, from pre-approval through the Ada County closing table. No handoffs. You always know where the loan stands.

First-time buyers

Down Payment Assistance

Chenoa, Arrive Home, and Essex/NHF national DPA we originate directly, plus the straight 2026 story on Idaho Housing's repayable 8% second, the FHLB Home$tart $15,000 grant, and who can actually offer each in Idaho.

Move-up buyers

Buy Before You Sell

Bridge financing that removes the contingency from your Boise or Meridian offer. Buy your next Treasure Valley home before the current one sells. Listing agents in a tight Ada County market: this is the deal-saver.

Self-employed buyers

Self-Employed Loans

Bank statement, 1099, and asset-qualifier paths for Idaho's contractors, farmers, and Coeur d'Alene small-business owners. Qualify on what your business actually makes, not what your Schedule C shows after deductions.

FHA / first-time

First-Time Home Buyer Loans

FHA at 3.5% down, $0-down USDA across the roughly 98% of Idaho that qualifies, and Conventional 97, plus Chenoa / Arrive / Essex DPA-paired structures. Designed for the Nampa or Pocatello buyer with real-life income and credit, not perfect-paper applicants.

Mike Certo is the Branch Manager at Cornerstone First Mortgage, licensed across Idaho from the Treasure Valley up to the Panhandle.

No handoffs in the middle of escrow.

What you get when you work with Mike:

For real estate agents

The lender you call when the deal has a complication.

Listing agents in Boise, Meridian, and Coeur d'Alene: when your buyer's offer is contingent on selling their existing home, our Buy Before You Sell program removes that contingency so the deal closes clean. Buyer agents across Ada and Canyon County: bring us self-employed buyers, complex-doc files, Sun Valley jumbo with student debt, investors with multiple Idaho rentals. We close the complex files.

FAQ

Common questions.

Why does ID Loan Experts have multiple websites?

Each lending niche has its own questions. We built dedicated Idaho guides for down payment assistance, buy-before-you-sell, self-employed loans, jumbo, investor, and first-time-buyer paths so a Boise or Coeur d'Alene buyer lands directly on the answers that matter. ID Loan Experts is the brand parent linking them, and Idaho Housing's Finally Home! programs run through every one.

What kind of borrowers do you typically work with?

First-time buyers in Nampa and Twin Falls using down payment assistance, self-employed borrowers who need bank-statement or 1099 loans, jumbo borrowers including St. Luke's and Saint Alphonsus doctors, investors using DSCR on Idaho rentals, and move-up buyers who need bridge financing to remove the contingency from their Treasure Valley offers.

Do you work with real estate agents?

Yes, we close the complex deals. Listing agents from Boise to Coeur d'Alene bring us their CCBS files (contract contingent on buyer sale) so we can provide bridge financing that removes the contingency. Buyer agents bring us self-employed, complex-doc, or unusual-property files across Ada, Canyon, and Kootenai County. Visit the For Agents page for the full referral playbook.
