Reviewed by the HomeMath editorial team Updated 2026-08-06

Key takeaways

Conventional refinance usually requires at least a 620 credit score.
You can borrow up to 80% of your home’s appraised value without paying private mortgage insurance (PMI).
Montana has no state income tax, which can slightly lower the overall cost of borrowing compared with states that tax income.

Refinancing a conventional loan in Montana can lower your monthly payment, shorten your loan term, or free up cash for other needs. Before you decide, understand how the loan works, what the eligibility requirements are, and which Montana‑specific factors might affect the bottom line.

How Conventional Refinancing Works

A conventional refinance replaces your existing mortgage with a new loan that has its own interest rate, term, and payment schedule. The new loan pays off the balance of your current mortgage, and you start fresh with the terms you secure.

Key Eligibility Factors

Credit score: Most lenders look for a minimum score around 620, though a higher score often yields better rates.
Equity: Lenders typically allow you to refinance up to 80% of the home’s appraised value without requiring private mortgage insurance (PMI). If you have less than 20% equity, you may need to pay PMI.
Debt‑to‑income (DTI) ratio: A DTI of 43% or lower is common, but some programs can accommodate higher ratios if you have strong compensating factors.
Stable income and employment: Documentation of consistent earnings helps verify that you can afford the new payment.

Montana‑Specific Considerations

Montana does not levy a state income tax, so you won’t lose a portion of your income to state tax when calculating affordability.
Most closings in Montana are handled by attorneys rather than title companies. Attorney fees are a normal part of the closing cost structure and should be factored into your total out‑of‑pocket expenses.
The state’s Montana Housing program offers assistance for first‑time homebuyers, but it does not apply to most refinance transactions.

Cost vs. Benefit

Monthly payment: A lower rate or longer term can reduce your payment, but extending the term may increase total interest paid.
Cash‑out option: If you have enough equity, you can pull out cash for home improvements or debt consolidation, but that increases your loan balance.
Break‑even point: Calculate how long it will take to recoup closing costs with the monthly savings. If you plan to stay in the home longer than the break‑even period, refinancing is more likely to be worthwhile.

FAQ

Can I refinance a conventional loan if I have less than 20% equity?

Yes, you can still refinance, but you’ll likely need to pay private mortgage insurance (PMI) because the loan‑to‑value ratio will be above the typical 80% threshold that allows you to avoid PMI.

What happens to my existing PMI if I refinance and reach 20% equity?

When you refinance into a new conventional loan that meets the 20% equity requirement, the new lender can cancel PMI on the new loan. The old PMI does not transfer; it ends when the original loan is paid off.

Does Montana’s lack of state income tax affect my mortgage interest deduction?

The federal mortgage interest deduction works the same regardless of state tax structure. However, because Montana does not tax personal income, you won’t receive a state tax deduction for mortgage interest, which can make the net benefit of the deduction slightly smaller compared with states that have an income tax.

How long does the refinancing process usually take in Montana?

Typical timelines range from 30 to 45 days, depending on factors such as appraisal scheduling, document collection, and the attorney’s workload during the closing. Promptly providing required paperwork can help keep the process on the shorter end of that range.
