3. Full Range of Loan Options for Every Situation
InterWest Mortgage is more than just a conventional lender. They provide a comprehensive suite of mortgage products that fit nearly every borrower type — from first-time buyers to veterans to those purchasing rural properties.
Here’s a breakdown of their most popular loan programs:
Conventional Loans
Perfect for borrowers with strong credit and stable income, conventional loans often feature lower interest rates and flexible terms. InterWest Mortgage helps clients secure conventional loans with as little as 3% down and offers refinancing options that can eliminate private mortgage insurance (PMI) once you reach 20% equity.
FHA Loans
Backed by the Federal Housing Administration, FHA loans are an excellent option for borrowers with lower credit scores or limited down payments. InterWest’s team simplifies the FHA process, guiding you through every step and ensuring you take advantage of the program’s affordable and accessible terms.
VA Loans
For eligible military members, veterans, and surviving spouses, InterWest Mortgage proudly offers VA home loans with zero down payment and no private mortgage insurance. Their loan officers are experts in the VA process and take special care to ensure veterans receive the benefits they deserve.
Rural Development (RD) Loans
Ideal for homebuyers in smaller or rural communities, USDA Rural Development loans make it possible to buy a home with no down payment and competitive interest rates. InterWest Mortgage has helped countless Idaho families — especially in areas like Shelley, Rigby, Ammon, and Rexburg — secure RD financing quickly and affordably.
Idaho Housing and Finance Association (IHFA) Loans
For Idaho residents, InterWest Mortgage is a trusted partner with the Idaho Housing and Finance Association (IHFA). This program offers down payment assistance, affordable mortgage rates, and educational resources to help Idahoans achieve homeownership — even if they thought it wasn’t possible.
Personalized Guidance From Start to Finish
One of the most significant differences with InterWest Mortgage is the personalized support you receive throughout the entire process. From the initial pre-approval to closing day, their loan officers work side-by-side with clients to explain every detail and help them feel confident in their decisions.
You’re never left guessing about your loan status or next steps. The team provides frequent updates, fast communication, and clear explanations — making it easy for even first-time buyers to understand complex mortgage terms.
They also offer digital tools for online applications, document uploads, and rate comparisons, so you can move through the process efficiently, no matter where you are in the U.S.
A Local Feel With Nationwide Reach
While InterWest Mortgage is deeply rooted in Southern Idaho, their lending services extend nationwide. Whether you live in Idaho Falls or on the opposite side of the country, you’ll get the same exceptional care, expertise, and competitive rates.
Their national reach allows them to assist borrowers in all 50 states while still maintaining the small-town customer service values that define their Idaho roots. That’s why so many clients continue to work with InterWest Mortgage — even after relocating out of state.
