Conventional loans are private‑sector mortgages that are not insured or guaranteed by the federal government. Lenders use your credit score as a quick gauge of how reliably you have managed debt in the past.

Typical credit‑score floor

Most lenders require a minimum score of 620 for a conventional loan. This threshold is set because borrowers below that level have historically shown higher default rates, which increases the lender’s risk.

Score ranges that affect pricing

  • 620 – 679: You will likely be approved, but the interest rate will be higher than the lender’s “best” rate.
  • 680 – 739: You qualify for moderate rates and may avoid some higher‑priced loan features.
  • 740 and above: You are in the “prime” or “super‑prime” category, giving you access to the most competitive rates and terms.

Why the thresholds exist

Lenders use statistical data that links credit‑score bands to default likelihood. By setting a floor, they protect themselves from loss while still offering mortgages to a broad segment of borrowers.

Montana‑specific considerations

  • Most home‑closing transactions in Montana are handled by attorneys rather than title‑company representatives. This can add a small flat fee but often provides more legal oversight.
  • The Montana Home Loan Program, administered by the state’s Department of Commerce, offers down‑payment assistance and may accept scores as low as 580** for qualified first‑time buyers, though the conventional‑loan floor of 620 still applies for standard private‑lender financing.

Keep in mind that a higher score not only improves your chances of approval but also reduces the overall cost of the loan.
