Current refinance guidelines, updated from one source.
One guideline source per program feeds every number here, and the page updates when a source does. Read the four cards as the program’s settings, not an offer: how far a conventional refinance may reach as a share of value, where mortgage insurance begins and ends, what an FHA streamline and a VA IRRRL ask of the loan being replaced, and where the credit floor and the ratio ceiling sit.
One-unit principal residence; mortgage insurance above 80%
95% is the conventional ceiling on a one-unit principal residence for a refinance that returns no cash, with 97% reserved for the first-time-buyer programs where the existing loan qualifies. Above 80% loan-to-value the new loan carries mortgage insurance; at or below it there is none, which is the line an FHA borrower crosses to shed the premium for good.
An existing FHA loan, refinanced with a net tangible benefit and a limited credit review
FHA offers two routes. The streamline requires no appraisal, limits the credit review, requires a net tangible benefit, and applies the previous loan’s seasoning and payment rules; the rate-and-term uses an appraisal and a full credit review and reaches 97.75% on a principal residence occupied the previous year. Both carry FHA mortgage insurance on the new loan.
An existing VA loan, no VA appraisal; seasoning of 210 days and six payments
An existing VA loan can be refinanced to a lower rate or from an adjustable to a fixed rate through the IRRRL: a 0.5% funding fee that can be financed and that exempt veterans do not pay, no appraisal required by VA, a net tangible benefit, and seasoning of 210 days and six payments on the loan being replaced. The home may be a primary, second, or investment property where the veteran previously occupied it.
DTI to 50%; jumbo from 660 on its lanes
Score and ratio for a Big Sky refinance: 620 is the conventional floor, 50% the automated ratio ceiling, and the finding weighs the rest of the file. The jumbo lanes, for balances above the conforming limit, start at 660, reach 90% of value on the headline lane, lend to $5,000,000, and hold the ratio to 50% on the fixed lanes with reserves per the lane.
| Program | Loan being replaced / occupancy | Maximum LTV | Conditions |
|---|---|---|---|
| Conventional rate-and-term (Fannie Mae / Freddie Mac) | One-unit principal residence | 95% | limited cash-out: the old loan, the closing costs and a purchase-money second roll in, incidental cash only; 97% where the existing loan is agency-owned and the first-time-buyer program allows; mortgage insurance above 80% |
| FHA streamline | Existing FHA-insured loan | No LTV test | appraisal not required; net tangible benefit; limited credit review; the previous loan’s seasoning and payment history apply; FHA mortgage insurance continues |
| FHA rate-and-term | Principal residence (owner-occupied the previous twelve months) | 97.75% | with an appraisal and full credit review; FHA mortgage insurance on the new loan |
| VA IRRRL | Existing VA loan; a home the veteran previously occupied | No LTV test | 0.5% funding fee (financeable; exempt veterans pay none); no VA appraisal; net tangible benefit; seasoning the later of 210 days and six payments |
| Jumbo rate-and-term (wholesale lanes) | Above the conforming limit | 90% | 660+ score on the headline lane, loans to $5,000,000, DTI to 50% on the fixed lanes; reserves and the appraisal count per the lane |
A refinance that returns cash is a cash-out refinance and is covered by the conventional, FHA, VA and jumbo cash-out programs; a line of credit that leaves the first mortgage in place is the HELOC program. Each carries its own leverage and its own rules.

What a rate-and-term refinance is — and how the file is qualified.
A rate-and-term refinance is simple to describe and particular in its rules. The four cards below cover what the new loan is and what it may pay off, which of the four programs applies to the loan being replaced, how the benefit test and the break-even decide whether the refinance pays, and what to do when the real goal is cash rather than terms.
For the program overview, see Lendmire’s refinance program, or the statewide guide at Refinance in Montana; when the goal is cash, see the cash-out refinance program.
One new loan replaces the old one
Mechanically the file is a payoff and a new note. The lender orders the payoff of the existing first mortgage, adds the closing costs and the prepaid items if the borrower rolls them in, includes a purchase-money second where one exists, and writes a new loan for the total on the chosen term. The homeowner keeps the home and the equity and exchanges the old terms for the new.
Four programs, one question: which applies
Four programs serve four situations. The conventional refinance fits most Big Sky homeowners, including FHA borrowers leaving the premium behind. The FHA streamline fits an FHA borrower who wants a lower payment with the least paperwork. The VA IRRRL fits a veteran with a VA loan, including a home once occupied and now rented. The jumbo lanes fit a balance the conforming limit cannot hold.
The benefit test and the break-even
A refinance pays when the owner keeps the loan past the break-even and the term reset does not give back the saving in interest. On an FHA streamline or a VA IRRRL the new loan must also deliver a net tangible benefit as the agency defines it, and VA requires the fees and costs to be recouped within its window when the new loan does not exceed the payoff. The Big Sky calculator below runs all three figures.
When the goal is cash, not terms
A rate-and-term refinance returns no cash. A Big Sky owner who wants money at closing, to consolidate debt, renovate, or buy another property, wants a cash-out refinance, which is a different program with its own leverage, seasoning, and cost, and is covered by the conventional, FHA, VA, and jumbo cash-out guides on this site; a home equity line that leaves the first mortgage in place is the third option.
Nothing in the formula is a quote. The new rate is a published weekly benchmark you can overwrite, the costs are your estimate, and the result is the shape of a Big Sky refinance, not its terms: the loan, the payment, the saving, the break-even, and the interest comparison, which a loan officer then prices in writing.
Where Big Sky’s mortgages were written — and what a refinance changes.
Three Census figures frame a Big Sky refinance file. Ownership says how much of the market holds a mortgage that can be rewritten, the median value says how much room a typical balance has under the leverage cap, and household income says what ratio a typical payment produces.
Market context only. Ownership and income describe the market; the appraisal and the pay stubs describe the file. The figures below say what is typical for Big Sky, and the calculator says what a particular balance and value produce.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct Big Sky neighborhoods, distinct refinance questions.
Big Sky is not one housing stock, and the refinance question changes with it: the vintage of the mortgage, the equity built since, the project review on a condominium, the conforming limit on a high-value home. Sort the neighborhoods by what a refinance there turns on.
Condominiums and condotels
Resort buildings in Big Sky divide into projects the agencies accept and projects they do not, and the refinance follows that line before any arithmetic. An accepted project refinances at the occupancy’s cap; a condotel or a building with hotel operations is a portfolio question. The loan officer collects the project documents first. Roughly 914 Big Sky households own their homes on the latest Census estimate — 84% of all households, the pool a refinance draws on.
Second homes and vacation homes
Owners of Big Sky vacation homes refinance to fix a rate or shorten a term as readily as owners of primary homes, at the second-home leverage the loan officer states, and the jumbo lanes carry the balances the conforming limit cannot. Cash out of a second home is the cash-out program; the IRRRL serves a veteran who once lived in the home. About 16% of Big Sky’s households rent — roughly 173 renter households on the latest Census estimate.
Primary residences in a resort town
Full-time Big Sky residents refinance on the full program: the principal-residence leverage in the snapshot, the mortgage-insurance line, the streamlines where the existing loan is FHA or VA, and the rescission period at funding. The resort market shapes the appraisal through its comparable sales; the file itself is the standard rate-and-term refinance. The median owner-occupied home value in Big Sky runs near $1,137,900 on the latest Census estimate.
High-value homes near the limit
Values in Big Sky put many homes above the conforming threshold, and a refinance there uses the jumbo lanes: a higher score floor, leverage set by the lane, reserves after closing, and a second appraisal on the largest loans. The county limit is confirmed by a loan officer; a balance that straddles it, with the costs included, is placed before the program is chosen. Median household income in Big Sky sits near $138,805 on the latest Census estimate.
Fixing a rate before the next season
Owners of Big Sky vacation and rental homes often carry adjustable loans taken when the home was bought, and the refinance that matters to them is the fixed rate before the next reset, timed to the season’s cash flow. Conventional, streamline, and IRRRL all allow it, the program follows the loan being replaced, and the benefit is certainty rather than a saving the calculator can price. Big Sky is home to about 2.4K people.
Seasonal rentals
The seasonal-rental refinance is an investment file: its own leverage, the income by the agencies’ method, no rescission period, and the lease or operating record in the documents. Big Sky owners most often use it to fix a rate before a reset or to shorten a term on a property they intend to keep. On a home at Big Sky’s median value, a conventional rate-and-term refinance at the leverage cap allows a new loan up to $1,081,000 — the existing loan, the closing costs, and a purchase-money second lien are what it may pay off.
Neighborhood moves the appraisal and the equity cushion; the program stays put. Wherever in Big Sky the home sits, the leverage, the mortgage-insurance line, the streamline and IRRRL conditions, and the credit figures are the ones in the snapshot.
Four reasons Big Sky homeowners rewrite the mortgage.
A mortgage is refinanced for a reason, and the reason picks the program and the term. These are four of the reasons that bring Big Sky homeowners to a rate-and-term refinance most often, with what each one asks of the file.
Shorten the term
A shorter term is the refinance that costs more each month and less in total. The ratio is tested on the new, higher payment, the appraisal and the cap apply as on any conventional file, and the saving shows up as interest avoided rather than as cash in the budget. The calculator sets the interest over the new term beside what remains on the old loan.
Get rid of mortgage insurance
An FHA borrower whose home has gained value can refinance into a conventional loan at or below the no-insurance line and leave the premium behind for good; a conventional borrower paying private mortgage insurance can do the same, or can ask the servicer to cancel it at the published line without refinancing at all. The appraisal sets the value, and the value decides which route is open.
Fix an adjustable rate
Fixing the rate trades a payment that can move for one that cannot. On a conventional loan the refinance is an ordinary rate-and-term file with an appraisal; on an FHA or VA loan the streamline or the IRRRL makes the same move with less paperwork. The benefit is certainty rather than a lower payment, and the break-even is measured against the risk removed.
Lower the monthly payment
A lower payment comes from a lower rate, a longer term, or both. The first is a saving; the second is a loan stretched across more years, which can cost more in interest even as the payment falls. The break-even on the costs and the interest comparison over the two terms are the figures that separate a refinance that pays from one that only feels like it does.
Estimate the new payment and the break-even on a Big Sky home before requesting a quote.
The calculator does the refinance arithmetic for a Big Sky home: current payment from the balance, the current rate and the years remaining; new payment from the new loan, the new term and the benchmark rate; the saving between them; the break-even on the costs; and the interest comparison that prices the term reset. Choose the program to apply its cap, its insurance line, or its fee.
Big Sky refinance savings and break-even estimate

Editable benchmark: 7.28% as of October 1, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $1,140,000 home value near Big Sky’s median owner-occupied value, a $798,000 current balance, a current rate and remaining term you enter, closing costs seeded at $16,000 as an editable placeholder (not a fee quote), a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated for Montana (U.S. Census Bureau). Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

Same home, four ways to refinance it.
Four programs, four files. The conventional refinance tests the value and the credit profile and sheds mortgage insurance at the line; the FHA streamline and the VA IRRRL refinance an existing government loan on a benefit test with little paperwork and no appraisal; the jumbo lanes carry the large balances with their own scores and reserves. Here is where each one fits a Big Sky owner.
Conventional, streamline, or jumbo.
The general route: any first mortgage on a home the borrower lives in, refinanced to a new fixed term with an appraisal, tested against the leverage in the snapshot, and carrying no mortgage insurance at or below the line. It rolls in the costs and a purchase-money second, returns no cash, and is how an FHA borrower leaves the premium behind. The price is a full file: income, credit, value. See the conventional loan program.
For a Big Sky owner whose loan is already FHA or VA, the streamline or the IRRRL is the lightest file on this page: no appraisal in most cases, a limited review, a benefit the new loan must deliver, and the agency’s own seasoning and payment-history rules on the loan being replaced. The FHA premium stays; the VA fee is financed or waived. Neither reaches a borrower whose loan is conventional. See the FHA and VA programs.
Above the conforming limit the agencies step aside and the wholesale jumbo lanes take over: a higher score floor, leverage set by the lane, reserves measured in months of payments, and a second appraisal on the largest loans. The rate-and-term jumbo refinance fits a Big Sky owner whose balance the conforming limit cannot hold, on a fixed, adjustable, or interest-only structure. See the jumbo loan program.
The loan being replaced points to the program, the balance points to conforming or jumbo, and the goal points to the term: shorter to save interest, longer to lower the payment, fixed to end the resets. What none of the four does is return cash; for that, the cash-out programs and the HELOC are the instruments, each with its own guide.
What to prepare for a Big Sky scenario review.
Most of what a refinance needs is already in a Big Sky homeowner’s files: the mortgage statement, the pay stubs, the insurance declaration, the tax bill. This list says what to gather and why each item matters to the file.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the transaction, the property, the automated finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
Most refinances are routine; the ones that are not usually trip on one of the details below. Read them before the appraisal is ordered on a Big Sky home.
Use these checks to keep the Big Sky file clean and fundable.
Before the appraisal is ordered: run the break-even on realistic costs, compare the interest over the new term with what remains on the old loan, and confirm which program the existing loan points to for the Big Sky home.
- Run the break-even: Closing costs divided by the monthly saving is the break-even in months.
- Weigh the reset: A longer term lowers the payment and can raise the total interest.
- Confirm who carries the loan: The remaining borrowers qualify on their own income and credit.
The costs are recovered only through the saving
Closing costs are paid from the loan or at the table, and the only thing that earns them back is the monthly saving. Divide the costs by the saving and the result is the number of months the Big Sky owner must keep the new loan to come out even; an owner planning to sell or refinance again before then is paying for a loan they will not use.
The term starts over unless you choose a shorter one
A new thirty-year loan on a balance that had ten years of payments behind it restarts the clock, and the interest over the new term can exceed what remained on the old loan even at a lower payment. The calculator sets the two side by side. A Big Sky owner who wants the saving without the reset chooses a term close to the years remaining, or shorter.
Removing or adding a borrower rewrites the note
The Big Sky file for a borrower change is an ordinary rate-and-term refinance with documents added: the decree, the death certificate, or the trust papers. The remaining borrower must carry the ratio on their own income, and the loan must be the type the existing loan points to. Where equity is paid out through the loan, the cash-out rules apply.
A second lien decides whether this is rate-and-term at all
A second mortgage taken when the home was bought can be paid off inside a conventional rate-and-term refinance. A second lien or a line of credit opened after the purchase cannot: paying it through the new loan makes the file a cash-out, with cash-out leverage and cost, even when the borrower receives nothing. The origin of the lien, not its balance, decides.
The rescission period on a principal residence
Federal law gives the borrower a short window after signing to cancel a refinance of a principal dwelling, so the payoff and the funding wait until it has passed. Second homes and investment property refinances have no such window. A Big Sky loan officer sets the signing date with the window in mind.
From a Big Sky scenario review to a new first payment.
From the first conversation to the new first payment, a Big Sky refinance moves through four stages, and the first one, the review, is where most files should be decided. The rest is documentation, the appraisal where the program needs one, and the closing.
Scenario review
Start with the balance, the current rate, the years remaining, the value, the score, and the costs. A Lendmire loan officer identifies the program the existing loan points to, runs the new payment, the saving, the break-even, and the interest comparison, and provides the terms in writing before anything is ordered.
Application and automated finding
The application turns the reviewed scenario into a file. For most Big Sky refinances the automated finding arrives quickly and lists the documents; for a streamline it is the agency’s checklist instead. Either way the appraisal, where one applies, is ordered only after this step.
Appraisal and underwriting
Value first, then verification. On a conventional or jumbo refinance the appraisal is the one input the Big Sky owner cannot control; on a streamline or an IRRRL there is none. Underwriting reads the finding’s conditions, the payoff, and the benefit test where it applies, and, where the file supports it, approves the loan on the terms the review set out.
Closing, rescission, and funding
The closing documents are signed, and on a principal residence the rescission period runs before the old loan is paid off and the new one funds. The Big Sky owner’s first payment on the new loan follows the funding date; the old loan’s final interest is in the closing figures, and nothing is skipped or forgiven.
A brokerage that runs the break-even honestly.
Why Big Sky owners bring a refinance to a brokerage: the programs are compared side by side, conventional, the streamlines, and jumbo, on the same numbers; the file is placed with the wholesale program that fits it rather than the only one a lender sells; and the answer, including the answer not to refinance, is given in writing first.
The break-even, run before anything else
The arithmetic is run on the owner’s own figures before an application exists: the saving, the months to break even, the term reset. When the refinance does not pay, the recommendation is to wait, and that recommendation is given as readily as the other.
Shopped across wholesale programs
Lendmire places the file with the wholesale program that fits it, conventional, FHA, VA, or jumbo, rather than with the one program a single lender sells. A Big Sky refinance is compared on the same numbers across programs before a route is chosen.
Terms in writing, before any fee
The review ends with written terms on a cautious value, and nothing is ordered until the Big Sky owner agrees the plan is worth an appraisal where one applies. The appraisal is not ordered for a plan the review has already ruled out.

Big Sky refinance FAQs
Plain answers to the questions Big Sky homeowners ask most about refinancing, in the order they usually ask them.
What is a rate-and-term refinance, and how is it different from a cash-out?
It is the refinance that changes the loan and leaves the equity alone. The balance, the costs, and a purchase-money second become one new loan on a new term; nothing comes back as cash. If a Big Sky owner wants money at closing, the cash-out programs are the right ones, and this page says so plainly rather than sizing the wrong loan.
When does refinancing actually make sense?
It makes sense for a reason you can name: a lower payment that recovers its costs, a shorter term that cuts the interest, an FHA premium that ends, an adjustable rate that becomes fixed, a name that comes off the note. It rarely makes sense for a payment that is only slightly lower, because the costs and the term reset eat the difference. The Big Sky review says which case you are in.
What does a refinance cost to close?
A refinance carries lender and third-party charges, prepaid interest and escrow deposits, and title and recording costs; on a VA IRRRL the funding fee is added unless the veteran is exempt. The figures depend on the loan, the program, and the state, and are stated in the written terms and on the Loan Estimate rather than on this page. They can be paid at closing or, within the program’s rules, rolled into the loan, where they raise the balance and lengthen the break-even slightly.
Can I get rid of mortgage insurance by refinancing?
Yes, in two situations. An FHA borrower can refinance into a conventional loan at or below the no-insurance line in the snapshot and leave the FHA premium behind for good; an FHA streamline does not do this, because FHA insurance stays with an FHA loan. A conventional borrower paying private mortgage insurance may not need a refinance at all: cancellation can be requested at the published line on the original value, and the servicer must end it on its own at the lower line. Where the home’s value has risen enough, a conventional refinance with a new appraisal puts the loan under the line sooner.
What is an FHA streamline, and who can use it?
The FHA streamline refinances an existing FHA-insured loan into a new FHA loan with no appraisal, a limited credit review, and a requirement that the new loan deliver a net tangible benefit as HUD defines it; the previous loan’s seasoning and payment-history rules apply, and FHA mortgage insurance continues on the new loan. Only a borrower whose current loan is FHA can use it, and a borrower who wants the premium gone refinances conventionally instead.
What if I want cash out of my home as well?
This page covers the refinance that changes terms. Cash at closing is the cash-out refinance, sized on the value and returning the difference, and this site has four guides for it, one by program. The line of credit behind a first mortgage worth keeping has its own guide. The two are compared on the same numbers in a Lendmire review.
Can I refinance to remove my ex-spouse, or to add someone, to the mortgage?
Yes. A name comes off a mortgage only when the loan is rewritten, so a refinance is the ordinary route after a divorce or a change in the household: the remaining borrower qualifies alone on income, credit, and the ratio, and the title is conformed at closing. Adding a spouse or a family member whose income helps the ratio works the same way. If the departing owner is paid their equity through the new loan, the file becomes a cash-out or a special-purpose refinance, which is a different program.
Is the rate in the calculator what I would get?
The calculator’s rate is a published survey average, not an offer. It exists so the payment, the saving, and the break-even can be estimated before a quote; the quote itself comes from the lender for the specific file and is given in writing. Edit the field freely.
Can I refinance an adjustable-rate mortgage into a fixed rate?
The move from adjustable to fixed is allowed on the conventional route and on both government streamlines, and it is the refinance whose value is measured in risk removed rather than dollars saved each month. The costs still apply, and the break-even is judged against the reset avoided.
How does a VA IRRRL work?
For a Big Sky veteran with a VA loan it is usually the lightest refinance available: limited documentation, no VA appraisal, the fee rolled in or waived, and a benefit test that protects the veteran from a refinance that does not pay. The seasoning clock on the old loan is the detail that most often sets the date.
Run the Big Sky refinance numbers, then get the terms in writing.
A Big Sky refinance starts with arithmetic and ends with written terms. Send the mortgage statement and the goal; the loan officer returns the program, the new loan, the payment, the saving, and the months to break even, and orders nothing until you agree.
