Current HELOC guidelines, updated from one source.
Every figure in this block comes from one guideline source and updates here when the wholesale programs change. These are the primary-residence terms; second homes and rentals follow their own tables, summarized under the ladder.
Of the home’s value, first mortgage included
Up to 90% combined loan-to-value is the primary-residence ceiling at the top tier; the tier ladder below shows how the ceiling and the line cap step down with the credit profile.
Credit score to start
Scores from 600 are eligible on a primary residence, with the smallest ceiling and cap; the ceiling and the cap step up with the credit tier, and a debt-to-income ratio above the reduced band needs a stronger profile.
Automated valuation on lines to $500,000
Lines run from $25,000 to $750,000 on a primary residence; lines up to $500,000 ordinarily use an automated valuation, and every line above that amount takes a full appraisal and a stronger credit profile.
Interest-only, then 17–25 years of repayment
The draw period is 3–5 years of interest-only payments, followed by 17–25 years of repayment; which structure applies depends on the program that offers the stronger cell at your tier.
| Credit profile | Max combined LTV | Max line | Valuation |
|---|---|---|---|
| 720+ | 90% | $500,000 | Automated valuation |
| 720+ | 75% | $750,000 | Full appraisal; primary residence only |
| 700+ | 85% | $500,000 | Automated valuation |
| 700+ | 75% | $750,000 | Full appraisal; primary residence only |
| 680+ | 85% | $500,000 | Automated valuation |
| 660+ | 85% | $500,000 | Automated valuation |
| 640+ | 80% | $500,000 | Automated valuation |
| 620+ | 70% | $400,000 | Automated valuation |
| 600+ | 60% | $400,000 | Automated valuation |
The 90% combined loan-to-value ceiling requires a 720 credit profile; lower tiers carry lower ceilings or smaller line caps, as the table shows. Second homes start at a 640 profile; investment property requires 700 and caps at 70% combined loan-to-value. Lines above the automated-valuation range: $750,000 at 75% with a full appraisal (700+ credit profile).

What a home equity line of credit is — and how the line is sized.
A home equity line of credit is a revolving lien, usually in second position: the home secures it, the line is sized from the equity, and the balance moves as you draw and repay. The pieces that decide the line in Big Sky are the value, the balance already on the home, the credit tier, and the occupancy.
For the program overview, see Lendmire’s home equity line of credit program, or the statewide guide at HELOC in Montana.
A line you draw on, not a lump sum
Think of it as a credit limit secured by the house. During the draw period you borrow and repay as you like, paying interest only on what is out; once the draw period ends, the balance converts to a fully amortizing repayment schedule.
Equity and the combined loan-to-value ceiling
Every lien counts toward the ceiling. The first mortgage, any existing second, and the new line are added together and divided by the Big Sky home’s value; the result must sit under the ceiling for the credit tier, and the line is sized to fit exactly there.
Your credit tier sets the ceiling and the cap
The program is a ladder: the higher the credit profile, the higher the combined loan-to-value ceiling and the larger the maximum line. A Big Sky owner at the top tier reaches the full ceiling; the tiers below it carry smaller ceilings or smaller caps, down to the floor.
Valuation, verification, and closing
Most Big Sky lines are valued by an automated model, with a secondary valuation at higher leverage and a full appraisal above the program’s threshold. Income is verified electronically first, through payroll-database matches or borrower-permissioned account connections, with documents as the fallback.
The result is an estimate, not a decision: a Big Sky valuation may land above or below the figure you enter, and the tier is set by the credit report, not by the score you guess. The ceiling and the cap themselves do not move within a tier.
Big Sky’s equity in figures — and how a line fits it.
A line is only as large as the equity behind it, and equity is set by what Big Sky homes are worth and what is still owed on them. These Census figures sketch the market that frames every file.
Market context only. Household income matters for the debt-to-income ratio, value for the ceiling, and the balance for the gap underneath it; the Census tells you the market, the file tells you the line.
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 equity pictures.
The Big Sky submarkets below show where the equity sits and what a line there turns on: the property type the lender sees, the valuation it takes, and the leverage the tier allows.
Waterfront and view homes
On a Big Sky waterfront home the model’s value is less certain, and larger lines route to an appraiser sooner. Flood coverage applies on a first-lien line where the property sits in a designated zone. On a one-unit principal residence at Big Sky’s median value, the primary-residence ceiling puts total liens near $1,024,110 — the line is what remains after the first mortgage balance; a second home starts at a higher credit floor and matches the primary column at the top tier, and a rental caps lower at every tier.
Second homes
The Big Sky vacation home is eligible for a line in the second-home column, which starts at a stronger credit profile and caps the line lower. The two programs are compared at each tier here as everywhere. The median owner-occupied home value in Big Sky runs near $1,137,900 on the latest Census estimate.
Year-round primary residences
Residents who live in Big Sky year-round are sized on the primary-residence column: the lowest floor, the highest ceiling, and the largest caps, with the high-balance lane available above the threshold. About 16% of Big Sky’s households rent — roughly 173 renter households on the latest Census estimate.
Short-term rental properties
A Big Sky short-term rental is eligible as investment property on the longer-runway program only, with its hard floor and flat ceiling. It must be vested in the owner’s name or a revocable trust rather than an entity. Median household income in Big Sky sits near $138,805 on the latest Census estimate.
Luxury homes above the threshold
Big Sky’s highest-value homes meet the program cap before the ceiling. On a primary residence the high-balance lane applies above the automated-valuation threshold, with a reduced ceiling, a stronger floor, and a full appraisal; second homes and rentals cap lower. Big Sky is home to about 2.4K people.
Rental condominiums and condotels
The Big Sky rental condo is eligible as investment property when vested in the owner’s name rather than an entity. The condotel form is the one exclusion that catches resort owners most often. Roughly 914 Big Sky households own their homes on the latest Census estimate — 84% of all households, the pool a home equity line is written for.
The property drives the file as much as the credit: the program accepts single-family homes, condominiums, townhomes, and small multi-unit homes with their own conditions, while manufactured homes, co-ops, mixed-use buildings, and homes vested in an entity are outside it.
Four ways Big Sky homeowners put a home equity line to work.
A line is flexible by design: draw for the project in front of you, repay, and draw again during the draw period. These are the four uses that bring Big Sky homeowners to a HELOC most often.
Consolidate higher-cost debt
Consolidation is one common use of the program in Big Sky: equity pays off unsecured balances, the owner manages one line, and the first mortgage is untouched. The decision turns on discipline, because the house is the collateral.
Fund the next property
Equity in a Big Sky home can become the down payment on a second home or a rental: the line funds ahead of the new purchase, the draw covers the cash to close, and it repays over the years while the first mortgage on the original home stays in place.
Cover a large planned expense
When the expense is known and the timing is near, a Big Sky owner opens the line sized to it, funds most of it at closing, and pays the bill from the draw. Later expenses can be covered by drawing again after the balance is paid down.
Renovate and repair without a refinance
Renovation is the classic Big Sky HELOC: the budget is uncertain until the walls are open, and contractors are paid in stages. The line has a seventy-five percent minimum draw at closing, so the owner should plan around it.
Estimate your Big Sky home’s available credit line before requesting a quote.
Size the line before you ask for a quote: the Big Sky value, the balance, the tier, and the occupancy are the only inputs, and the ceiling and cap come from the same guideline source as the snapshot above. The result is an estimate of the credit line, not a decision, and it does not show a rate or a payment.

Same equity, four very different ways to use it.
A Big Sky owner choosing between a HELOC, a cash-out refinance, a closed-end second mortgage, and unsecured credit is choosing a structure, not just an amount. Here is how each one works and where it fits.
A line, a refinance, a closed-end second, or unsecured credit.
A revolving second lien sized by equity and tier, drawn at closing and then as needed, interest-only until repayment, and the first mortgage untouched. A fit when the need is staged, repeated, or uncertain in size, and the first mortgage is worth keeping.
A refinance resets the whole first mortgage to take cash out once. It suits the Big Sky owner who wants a single lien and a known amount, and who is content to replace the existing mortgage rather than keep it. For the first-mortgage route, see Lendmire’s refinance program.
A second mortgage that funds once in a lump sum and amortizes from the first payment. No draw period, no revolving balance. It fits when the Big Sky need is a single known amount, such as one contractor bid, and the owner wants a fixed schedule from day one.
Unsecured credit fits small, short needs and asks nothing of the home; it costs more and caps lower, so as the amount grows a line secured by the Big Sky home takes over, and a refinance or a closed-end second takes a lump sum.
What to prepare for a Big Sky scenario review.
What the lender looks at on a Big Sky line, and what you can gather before the review.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the occupancy, the property, the lien position, and the income picture. Nothing here is legal or tax advice.
Local details that can change the line.
The ceiling and the cap are only part of the answer; these are the details that decide what a Big Sky line actually becomes once the file is reviewed.
Use these checks to keep the Big Sky file clean and fundable.
Run these before asking for a quote: know where the credit profile lands on the ladder, know which valuation applies, and know that the home is vested and occupied the way the program requires.
- Confirm the tier: a self-pulled score can land a tier away from the one the program uses.
- Know the valuation: a recent renovation may not show in an automated value.
- Know the history: a foreclosure-family event is declined on one program and seasoned on the other.
The credit tier decides the ceiling and the cap
The score that counts is the primary wage earner’s, on a single-bureau model, from a report the lender pulls; a self-pulled score can land a tier away. Each tier on the ladder carries its own ceiling and cap, so a Big Sky line can change size without the value or the balance moving at all.
Automated valuation on most lines, appraisal on the largest
Most Big Sky lines are valued by an automated model; a higher combined loan-to-value may bring a secondary valuation, and every line above the program’s threshold takes a full appraisal with a stronger floor and a reduced ceiling. The model’s value, not the owner’s, is the one the ceiling is applied to.
Housing history and derogatory credit
Recent mortgage or rent lates close the program, and the lookback is longer at the lower tiers. A bankruptcy seasons four years after discharge on both programs; a foreclosure, deed-in-lieu, or short sale is seasoned on one program and declined on the other.
The debt-to-income ratio on the full draw
The line qualifies on the interest-only payment at the maximum draw, added to every other obligation and divided by verified income. The ratio ceiling is reduced at the lower credit tiers, so a Big Sky owner near the floor has less room for debt.
Lien position and the first mortgage
The program writes first and second liens. Behind an existing mortgage the line is a second lien; on a Big Sky home with no mortgage it is the first. Either way, the line has a three to five year interest-only draw period, and then repayment begins.
From a Big Sky prequalification to a funded line.
The Big Sky process is built around verification you authorize rather than documents you gather: identity, income, the property, and the valuation are each checked in order, and a prequalified offer comes before the hard credit pull.
Scenario review
Start with the value, the balance, the tier, and the occupancy. A Lendmire loan officer sizes the Big Sky line against the two programs, explains the structure that fits, and provides the terms in writing.
Prequalification
Nothing is committed at prequalification: the lender confirms the Big Sky property, the identity, the tier, and the valuation, then presents an offer. Accepting it is what triggers the hard credit pull.
Verification and valuation
The Big Sky valuation path is set by the line: automated on most lines, with a second opinion at higher leverage and an appraiser above the threshold. Income and obligations are verified in parallel.
Closing and funding
Documents are signed by remote online notarization where Montana permits it, otherwise a mobile notary meets you in person. Funds disburse by electronic transfer to a connected account or by mailed check, and the minimum closing draw funds with the line.
A brokerage that matches the line to the equity.
The value of a brokerage on a home equity line is comparison: two programs with different ladders, different runways, and different rules on history and property, read side by side for the Big Sky file and quoted in writing.
Two programs, the stronger cell quoted
A single program is a single answer; two programs are a choice. The Big Sky owner at a given tier sees the higher-leverage cell and the longer-runway cell side by side, and the review quotes the one that serves the use.
Structure matched to the use
A staged renovation, a consolidation, a down payment on the next property, and a reserve are four different uses, and the size of the line, the closing draw, and the runway should follow the use. A Big Sky scenario review starts there.
Licensed, consumer-purpose, in writing
Lendmire is licensed in sixteen states for consumer mortgages, the line is a consumer-purpose transaction with full disclosures, and every figure a Big Sky owner relies on, from the ceiling to the draw to the terms, is provided in writing by a licensed loan officer.

Big Sky HELOC FAQs
Plain answers to the questions Big Sky homeowners ask most about a home equity line of credit, in the order they usually ask them.
What is a HELOC, and how is it different from a home equity loan?
A HELOC is a line with a closing draw and the rest drawn as needed, with interest-only payments during the draw period and a longer repayment period after. A home equity loan funds once and repays on a set schedule. Both usually sit behind the first mortgage, and either can be a first lien on a home with no mortgage; the line is the flexible one.
How much can I borrow on a HELOC in Big Sky?
As much as sits under the ceiling for your tier, up to the cap. On a primary residence the ceiling is highest at the top tier and steps down with the credit profile; a second home starts at a higher floor with less leverage at the lower tiers and matches the primary column at the top, and a rental caps lower at every tier.
What credit score do I need for a HELOC?
The floor is in the snapshot above. More useful than the floor is the ladder: find the tier your report lands in and read the ceiling and the cap beside it, because that is the line the program supports.
Do I need an appraisal for a HELOC?
Most lines are valued by an automated model rather than an appraiser’s visit, with a secondary valuation at higher leverage. A full appraisal is required on every line above the program’s threshold, which is shown in the snapshot, and on the high-balance lane for a primary residence.
How do the draw period and the repayment period work?
The draw period is the flexible phase, with interest-only payments; the repayment period is the amortizing phase. The program requires a large share of the line to be drawn at closing, so the balance is never zero on day one.
Can I get a HELOC on a home I am about to sell?
A listed home, or one listed recently, is out on the higher-leverage program and out in some states on the longer-runway program. If the goal is equity for the next purchase before selling, the line is opened ahead of the listing and repaid from the sale.
How does a HELOC close, and when do I get the money?
The signing is remote or mobile, the file clears a manual quality check before it closes, and on a primary residence the funds arrive after the federal rescission period, by electronic transfer or check. The closing draw is part of the funding on both programs.
My rental is in an LLC. Can it get a HELOC?
No; entity vesting is outside both programs. A Big Sky investor can move the rental into individual names before closing, or look at an investor cash-out refinance built for entity-held property.
Is the rate on a HELOC fixed or variable?
The rate is variable for the life of the line on both programs. What that means in dollars for a Big Sky owner is something a loan officer provides in writing after the review; the program pages state parameters, not terms.
Is there a minimum line amount or a minimum draw?
Yes: there is a minimum line and a minimum draw, and both figures sit in the snapshot on this page. The closing-draw rule is the one that surprises Big Sky owners planning a reserve: the required initial draw, most of the line, funds at closing whether the project is ready or not.
Size the Big Sky line, then get the terms in writing.
A Big Sky home equity line begins with a conversation about the equity and the use. Lendmire compares the two programs at your tier and puts the stronger one in writing.
