Current HELOC guidelines, updated from one source.
The figures below are the primary-residence tier of the program, read from Lendmire’s centralized guideline source and refreshed on this page as the wholesale programs change: the combined loan-to-value ceiling, the credit score to start, the line sizes, and the draw and repayment periods.
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
A 600 score opens the program on a primary residence; the leverage ceiling and the maximum line step up through the tiers from there, some tiers sharing a cell, and second homes and rentals carry higher floors.
Automated valuation on lines to $500,000
$10,000 to $750,000 is the primary-residence line range; an automated valuation ordinarily serves lines to $500,000, and a full appraisal, a higher floor, and a reduced ceiling apply above it.
Interest-only, then 17–25 years of repayment
Draw for 3–5 years on interest-only payments, then repay over 17–25 years on a fully amortizing schedule; the shorter structure buys more leverage, the longer one a longer runway.
| 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.
What makes a HELOC different from a refinance is that nothing about the first mortgage changes. In Mackinac Island, the line is written behind it, sized by the equity and the tier, drawn at closing and then as needed, and repaid over the years that follow. Here is how each piece works.
For the program overview, see Lendmire’s home equity line of credit program, or the statewide guide at HELOC in Michigan.
A line you draw on, not a lump sum
The line is a credit limit, not a check: a Mackinac Island owner draws against it as needs arrive, pays interest only on the outstanding balance during the draw period, and amortizes whatever remains over the repayment period that follows.
Equity and the combined loan-to-value ceiling
The lender measures every lien against the value: the first mortgage balance plus the new line, divided by what the Mackinac Island home is worth. That combined loan-to-value ratio may reach the ceiling for your tier, and the line is whatever room remains under it, capped by the program maximum.
Your credit tier sets the ceiling and the cap
Start with the tier ladder under the snapshot for a primary residence: find the credit profile, read the ceiling and the cap beside it. Debt-to-income, vesting, property type and listing status also decide eligibility. Second homes and rentals carry their own floors and ceilings, which the calculator applies.
Valuation, verification, and closing
Most Mackinac Island 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.
This is the same math the lender runs on a Mackinac Island file. The only moving parts are the value, which comes from the valuation, the balance, which is whatever the payoff statement says, and the tier, which the credit report decides.
Mackinac Island’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 Mackinac Island homes are worth and what is still owed on them. These Census figures sketch the market that frames every file.
Citywide figures provide general market context, not an appraisal or an income calculation. Take these figures as the range of equity positions in the market, not as a forecast of any one line. The lender values the specific home, subtracts the specific balance, and applies the specific tier.

Distinct Mackinac Island neighborhoods, distinct equity pictures.
A line follows the house. These Mackinac Island submarkets differ in the property types the program accepts, the valuation each needs, and the equity a typical owner holds, which is what the cards below describe.
Waterfront and view homes
On a Mackinac Island 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 Mackinac Island’s median value, the primary-residence ceiling puts total liens near $659,970 — 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 Mackinac Island 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. Roughly 86 Mackinac Island households own their homes on the latest Census estimate — 49% of all households, the pool a home equity line is written for.
Luxury homes above the threshold
The luxury file in Mackinac Island is about the cap and the lane: above the threshold the ceiling drops and an appraisal is required, and the owner weighs the largest line against the standard terms on a smaller one. About 51% of Mackinac Island’s households rent — roughly 90 renter households on the latest Census estimate.
Rental condominiums and condotels
A Mackinac Island condominium rented to guests is an investment-property file: a hard credit floor, a flat ceiling, and the longer-runway program only. A condotel, a unit operated like a hotel room, is excluded outright on both programs. Mackinac Island is home to about 561 people.
Short-term rental properties
A Mackinac Island 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 Mackinac Island sits near $95,000 on the latest Census estimate.
Year-round primary residences
The Mackinac Island primary residence is the strongest column in the tables, and local owners who live in the resort town full time reach it: the full ceiling at the top tier and the largest lines the program writes. The median owner-occupied home value in Mackinac Island runs near $733,300 on the latest Census estimate.
Whatever the neighborhood, the program rules are the same: the value is confirmed by the lender’s valuation, the balance by the payoff, the tier by the credit report, and the property type by the program’s eligibility list. Condominiums and multi-unit homes have their own conditions; entity-vested homes are not eligible.
Four ways Mackinac Island homeowners put a home equity line to work.
Mackinac Island owners open home equity lines for a handful of reasons that repeat: the renovation, the higher-cost debt worth consolidating, the next property, and the large expense that arrives on its own schedule.
Cover a large planned expense
A line gives a Mackinac Island household a planned source for the large expense: the closing draw covers the bill, repayment follows over the years after, and during the draw period the line stays available for the next expense as the balance comes down.
Bridge the move between homes
Buying before selling is easier with a line on the current Mackinac Island home: the down payment on the new house comes from equity, and the line is paid down when the old home sells. The higher-leverage program does not accept a home already listed for sale, so the line is opened first.
Repay and draw again as needs change
The line revolves through the draw period: a Mackinac Island owner takes the closing draw, pays the balance down, and draws again when the next repair, income gap, or opportunity arrives, up to the limit. The program requires most of the line drawn at closing; the remainder waits.
Fund the next property
Equity in a Mackinac Island 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.
Estimate your Mackinac Island home’s available credit line before requesting a quote.
This sizer runs the program’s own math on your Mackinac Island inputs: value times the ceiling for the tier, minus the balance, capped at the program maximum, with the equity, the leverage, the closing draw, and the valuation path alongside. A loan officer provides the rate and payment in writing.

Same equity, four very different ways to use it.
Equity can be reached four ways, and the structures differ more than the headlines suggest: a line that stays open, a refinance that replaces the first mortgage, a closed-end second that funds once, or unsecured credit that costs more and secures nothing.
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.
One mortgage, one closing, cash in hand: a cash-out refinance is the simplest structure, and the most consequential, because it replaces the first lien entirely. The amount of equity it reaches depends on the size of the new loan. 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 Mackinac Island 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 Mackinac Island home takes over, and a refinance or a closed-end second takes a lump sum.
What to prepare for a Mackinac Island scenario review.
Most verification runs through permissioned connections; have these ready for a Mackinac Island review all the same.
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 Mackinac Island line actually becomes once the file is reviewed.
Use these checks to keep the Mackinac Island file clean and fundable.
A clean Mackinac Island file answers three questions in advance: what tier, what valuation, and whether the property and its title are inside the program.
- Confirm the tier: the lender’s report sets the tier, and the ladder sets the ceiling and cap for it.
- Know the valuation: the model’s value, not the owner’s estimate, is what the ceiling applies to.
- Plan the draw: later draws carry minimums on one program.
The credit tier decides the ceiling and the cap
The tier is read from the lender’s report, not an app. On a Mackinac Island file the difference between two adjacent tiers can be a full step in the ceiling and a different line cap, which is why the tier is confirmed before anything is sized.
Automated valuation on most lines, appraisal on the largest
An automated valuation is a model’s opinion of the Mackinac Island home from public records and sales; it may not reflect the value a recent renovation added. Where the line is large enough to require a full appraisal, the appraiser’s figure replaces it.
The minimum draw at closing and the draw mechanics
Both programs require a large share of the line to be drawn at closing, so a Mackinac Island owner who wants a mostly undrawn reserve should size the line to the amount they are willing to take at funding. Later draws carry their own minimums on one program.
Occupancy changes the floor and the ceiling
The three occupancy columns differ most at the floor: primary residences reach the furthest on the floor and the high-balance lane, second homes start a step behind on the floor, and investment property has a hard floor and a flat ceiling.
A home listed for sale is outside the higher-leverage program, and in some states both
Sequencing matters for the owner who wants to buy before selling: the line on the current Mackinac Island home is opened and funded before the listing goes live. A recent listing takes the home outside the higher-leverage program, and outside both programs in some states.
From a Mackinac Island prequalification to a funded line.
From the first conversation to a funded line, a Mackinac Island file follows a set sequence. Here is what happens at each step and what the owner does.
Scenario review
A Mackinac Island scenario review is a sizing exercise: value, balance, tier, occupancy, and the use of the line. The loan officer confirms eligibility against the program rules and puts the terms in writing.
Prequalification
Prequalification runs in a set order on a Mackinac Island file, with a soft pull first and the hard pull only after a prequalified offer is accepted. The valuation and the ceiling check happen here, before any commitment.
Verification and valuation
Income is verified electronically first, through payroll-database matches or permissioned account connections, with documents as the fallback. The automated valuation stands on most lines; an appraisal applies where the size requires it.
Closing and funding
The Mackinac Island closing is signed remotely or with a mobile notary, the right-to-cancel period runs where it applies, and the line funds to a connected account or by check. From then on, draws and payments run on the lender’s portal.
A brokerage that matches the line to the equity.
A brokerage sees both programs; a single lender sees one. For a Mackinac Island owner that difference shows up in the ceiling, the cap, and the runway quoted at your tier, because Lendmire quotes the stronger cell and explains the trade.
Two programs, the stronger cell quoted
At every credit tier the two wholesale programs offer different ceilings, caps, and runways. Lendmire reads both for the Mackinac Island file and quotes the stronger cell, explaining what the leverage costs in runway, or the runway in leverage.
Structure matched to the use
The loan officer’s first question is what the line is for, because the use decides how much to draw at closing, whether a longer runway matters, and whether a line is even the right structure next to a refinance or a closed-end second.

Mackinac Island HELOC FAQs
What a line is, how much it can be, what credit it takes, whether an appraisal is needed, and how the draw and repayment work, answered for Mackinac Island owners.
What is a HELOC, and how is it different from a home equity loan?
The difference is the draw period. A home equity line stays open for years so a Mackinac Island owner can draw in pieces; a home equity loan is a single advance with a fixed repayment path. The program on this page is the line.
How much can I borrow on a HELOC in Mackinac Island?
Use the calculator above: enter the value, the balance, the tier, and the occupancy, and it returns the line the program tables support. The figure is an estimate until the valuation and the credit report set the real value and tier.
What credit score do I need for a HELOC?
The floor and the top tier are both in the snapshot above: a Mackinac Island owner at the floor is eligible with the smallest ceiling and cap; at the top tier the full ceiling and the largest cap apply. The ladder under the snapshot shows every step between them.
Do I need an appraisal for a HELOC?
Not for most Mackinac Island lines. The automated valuation draws on public records and comparable sales, so it may not reflect a recent renovation. Where the line is large enough to require an appraisal, the appraiser’s value replaces the model’s.
How do the draw period and the repayment period work?
Draw, then repay. In the first phase a Mackinac Island owner can borrow, repay, and borrow again up to the limit, paying interest only on the balance; in the second phase no new draws are allowed and the balance pays down on schedule. The rate is variable through both.
Is there a minimum line amount or a minimum draw?
Yes: a minimum line and a minimum draw apply, both in the snapshot on this page, and the minimum line shown is Michigan’s own, below the program’s standard minimum. The closing draw surprises Mackinac Island owners planning a reserve: a minimum share of the line is drawn at closing on both programs, ready project or not.
Can I get a HELOC on a second home or a rental property?
Yes. The occupancy decides the floor and the ceiling: primary residences reach the furthest, second homes sit a step behind, and rentals carry the tightest terms on the longer-runway program.
Is the rate on a HELOC fixed or variable?
Both programs carry a variable rate from the first draw through the last payment of the repayment period. A loan officer provides the actual terms in writing; nothing on this page is a quote.
How is my debt-to-income ratio calculated on a HELOC?
The line is qualified on the interest-only payment at the maximum draw, added to every other monthly obligation and divided by total verified income. The ratio ceiling is reduced at the lower credit tiers, and a ratio above the reduced band needs a stronger profile.
How does a HELOC close, and when do I get the money?
A Mackinac Island line closes with a notary, remote or in person, and funds by transfer or check after any applicable cancellation period. The timing depends on verification and valuation; a loan officer sets expectations for your file.
