Side-by-side comparison of mortgage costs, property taxes, closing costs, and homeowners insurance between California and Idaho. Updated for 2026.

Estimated PITI payments assuming 10% down, 6.5% rate, 30-year fixed mortgage with PMI.
The monthly payment difference is $2,520/month — that’s $30,240/year or $907K over the life of a 30-year loan. Buying in Idaho is the more affordable option based on median home prices with identical loan terms.
Based on the 28% debt-to-income rule — your monthly housing payment should not exceed 28% of gross monthly income.
To afford the median home in California, you need a household income of approximately $232K/year. In Idaho, you need $124K/year — less by $108K/year. That $108K income gap means Idaho is accessible to a significantly wider range of households.
Idaho offers meaningfully lower home prices than California, with median prices running 46% less ($365K difference). This gap translates to both a smaller loan and lower monthly payments. First-time buyers priced out of California may find Idaho far more accessible, particularly when combined with local down payment assistance programs.
Property tax rates are similar in both states (California: 0.73%, Idaho: 0.63%), so taxes shouldn't be the deciding factor in your relocation decision. Instead, focus on differences in home prices, insurance costs, and state-specific programs. Both states collect roughly comparable property tax revenue relative to home values.
Insurance costs favor Idaho at $1,600/year versus $2,200/year in California, a difference of $600 annually. While not the largest cost factor, this adds up to over $6K over a decade of homeownership. Shop multiple carriers in either state — actual premiums depend on your specific property, coverage level, and claims history.
Closing costs are a one-time but significant expense. California averages $9K in closing costs (1.2% of purchase price) while Idaho averages $6K (1.5%). The difference is spread across title insurance, attorney fees, and recording costs rather than a single large tax. Budget for these upfront costs — they affect how much cash you need on hand at closing.
Both states offer down payment assistance for first-time buyers. California's CalHFA Dream For All provides Up to 20% shared appreciation loan, while Idaho's Idaho Housing DPA offers Up to 7% second mortgage. These programs can significantly reduce your upfront costs and make homeownership accessible even if you haven't saved a full 20% down payment. Check eligibility requirements on each state's housing finance agency website — income limits and purchase price caps apply.
The bottom line: Idaho homes cost $365K less than California on average. That translates to roughly $2,520 less per month in total housing costs if you choose Idaho. For most buyers, this price gap is the single biggest factor — it affects your loan size, monthly payment, and how quickly you build equity.
