Factors That Impact the Cost to Build a House in Idaho

  • Location – Urban vs. rural areas, surrounding home values
  • Property type – Raw land, infill lot, teardown rebuild
  • House size – Square footage, number of bedrooms/bathrooms
  • Layout and design – Simple vs. complex shapes and angles
  • Number of stories – Single vs. multi-level
  • Materials used – Grades, finishes, and types of products selected
  • Energy efficiency upgrades – Insulation, windows, HVAC systems
  • Labour rates – Local construction crews and subcontractor pricing
  • Customizations – Unique architectural details, visibility upgrades
  • Permits and fees – Development, municipal, utility charges
  • Site considerations – Sewer vs. septic, grading, landscaping, etc.
  • Contractor efficiency – Production vs. custom builders, change orders

Saving on Costs Through the Build Process

  • Use efficient floor plans that minimise complex framing shapes
  • Build on flat land requiring less grading and foundations work
  • Install roof trusses vs. stick framing for quicker erection
  • Use standardised material sizes to reduce custom cuts/waste
  • Partner with an experienced local production builder familiar with normative regional pricing
  • Research prices thoroughly yourself if acting as own general contractor
  • Use open flow kitchens with single runs for plumbing and electrical
  • Install carpet and vinyl instead of premium hardwoods and stone
  • Buy appliances, sinks, faucets and fixtures on sale or off the shelf vs custom
  • Eliminate unnecessary decorative touches and overbuilding rooms

House Building Financing Options

  • Construction Loans: A construction loan covers building costs in instalments as specific project milestones are met. Typically provided up to 9 months with variable rates. Require approximately 20% down payment. Interest payments due during the build.
  • Bridge Loans: A short-term temporary loan used to purchase land or secure financing between closing on an existing home sale and new home construction. Usually 12 months or less term at higher interest rate. Useful when timing between transactions don’t align perfectly.
  • 203k Rehab Mortgage: FHA insured loan covering purchase and renovation costs for distressed homes. Allows buying and rebuilding a rundown house. Require only 3.5% down payment. Limited to 1-4 unit residential buildings. Low credit score options available.
  • Cash Savings: Self-financing a new custom build often results in better pricing control and timing flexibility. Many Idaho builders offer discounts from 5-20% for cash deals avoiding bank loan costs and delays. Money can come from a home equity line if available.
  • Owner Financing: Some builders or land developers may directly hold a mortgage for qualified buyers if bank loan terms are unfavourable. This allows periodic payment plans tied directly to the property itself.

Building vs. Buying a House: Key Differences

Constructing a new custom residence enables you to dictate every facet of design from overall aesthetics down to the tiniest interior fittings. If a recently built production home fails to offer the exact floorplan innovations or highly-specified finishes your family requires, building from scratch is preferred. Despite typically higher base pricing, personalising a home through components like open concept entertaining venues, chef’s kitchens, spa bathrooms, optimised storage, integrated smart controls, electric vehicle charging, and beyond allows creating an ideally-tailored abode.

Alternatively, purchasing an existing or spec home provides move-in readiness, established neighbourhoods, and landscaping maturity at lower risk. Though less control over layouts and materials, resale homes present value opportunities to secure coveted locations or modernised amenities without long construction timelines. Whether modernising interiors over time or selecting a new community with preferred society dynamics, buying can achieve similar customization through strategic renovations or furnishings to call any dwelling your own. Weighing costs against customization flexibility helps determine the optimal new home procuring method.


Building a new home in Idaho allows you to customise the perfect sanctuary for your family’s needs and lifestyle aspirations. With costs averaging $158 per square foot, expect to spend $316,000 to $450,000 constructing a typical 2,000 square foot residence over an 8 to 12 month schedule. Carefully weighing key factors like design, finishes, property details, and financing will enable realising your dream Idaho living environment while controlling budgets.
