What this Montana mortgage calculator shows

- Add $280/month for property tax at the state average
- Add $80–$200/month for homeowners insurance
- Add PMI if putting less than 20% down (roughly 0.3%–1.5% of loan amount annually)
- Add HOA dues if applicable (varies widely)
Montana-specific considerations
Rates shown are indicative state-level averages aggregated from public lender data. Actual offers depend on credit score, down payment, debt-to-income ratio, loan program (conventional, FHA, VA, USDA), and the specific lender. Always compare at least three lenders and request a Loan Estimate within three business days per the TILA-RESPA Integrated Disclosure rules.
Refinance vs. new purchase
If you already own a home in Montana, use the same calculator with your current balance to model refinance scenarios. A common rule of thumb: refinance makes sense when you can cut the rate by 0.75%+ and you plan to stay in the home long enough to cover closing costs (typically 2–5% of the loan amount).
