When it comes to building a new home, the excitement of customizing every feature—from floor plan to finishes—can overshadow one crucial step: financing. Whether you’re planning to build in Idaho Falls, Rexburg, Rigby, Shelley, Firth, Pocatello, or Iona, understanding the new construction loan process and your financing options is essential. That’s where InterWest Mortgage comes in.
At InterWest Mortgage, we not only offer some of the most competitive construction loan rates in Southeast Idaho, but we also walk you through every step of the process, so you’re never navigating the complex world of home financing alone.
Why You Should Talk to a Lender First Before Building or Buying New Construction
Many people assume the first step in building a home is hiring a contractor or finding a suitable piece of land. In reality, your first conversation should be with a trusted lender. Here’s why:
- Pre-approval provides clarity on your budget: Knowing how much you can borrow helps you design a home within your financial comfort zone.
- Builder relationships: Lenders like InterWest Mortgage often have preferred relationships with builders, which can streamline the process and reduce costs.
- Avoid surprises: Understanding interest rates, down payment requirements, and timelines early prevents delays or financial setbacks later.
By connecting with InterWest Mortgage early in the process, you’re better prepared to work with builders, realtors, and even city officials on permitting and zoning.
Loan Options for New Construction in Idaho
Financing a new build isn’t the same as buying an existing home. Construction loans are more complex, but with InterWest Mortgage, the process is simplified and streamlined for a more straightforward experience. We offer a variety of construction and end-loan options suited for residents in Idaho Falls, Rexburg, Rigby, Shelley, Firth, Pocatello, and Iona.
1. Construction-to-Permanent Loan
This popular option combines two loans into one:
- Phase 1: Funds are released to the builder in stages (called draws) as construction progresses.
- Phase 2: Once construction is complete, the loan automatically converts to a permanent mortgage (usually a 15- or 30-year term).
Why it’s ideal: You only have to pay closing costs once, and you can lock in your mortgage rate early, which is great for the ever-changing market in Idaho.
2. Stand-Alone Construction Loan
This is a short-term loan (usually 12 months) to fund the construction phase only. After the home is built, you’ll need to apply for a traditional mortgage to pay off the construction loan.
Why it’s ideal: It can offer more flexibility during the build, especially if you’re selling another property or expecting a financial change in the near future.
3. Owner-Builder Loan
Planning to act as your general contractor? This is a specialized loan that supports self-managed construction.
Important note: These loans can be harder to qualify for and require solid experience and a detailed plan. InterWest Mortgage can help assess if this is right for you.
4. FHA Construction Loans
Backed by the Federal Housing Administration, these are great for buyers with lower credit scores or smaller down payments. InterWest Mortgage is experienced in FHA lending and can guide you through the extra paperwork.
Available in: Idaho Falls, Rexburg, and Pocatello, where FHA loans are standard among first-time buyers.
5. VA Construction Loans
For eligible veterans or active-duty military members, VA construction loans offer benefits like no down payment and competitive rates.
Note: These require VA-approved builders and strict inspections, but we’ll walk you through every detail.
