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
The ceiling counts every lien together: the first mortgage balance plus the new line, divided by the home’s value, may reach 90% on a primary residence at a 720 profile, with lower ceilings at lower tiers.
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 $10,000 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
3–5 years to draw, 17–25 years to repay: the two wholesale programs behind the table trade leverage for runway, and the file lands on whichever offers the stronger cell at the credit 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 Michigan 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; for rentals held by an investor, see the investment property HELOC.
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
Available equity is the gap between the ceiling and the balance already on the home. A Michigan home with a small first mortgage has a large gap; a recently purchased home with a high balance may have little room under the ceiling even at the top tier.
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 Michigan 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
A Michigan line closes on the lender’s own process: electronic income verification first, an automated valuation on most lines, automated eligibility checks followed by a manual quality check, notarization, and funding by electronic transfer or check.
The calculator applies this to a Michigan scenario: enter the value and the balance, pick the credit tier and the occupancy, and the available line follows from the ceiling and the cap the program tables assign to that cell.
Michigan’s equity in figures — and how a line fits it.
Equity in Michigan is a statewide picture made of local ones: values, ownership tenure, and incomes differ from one market to the next, and each shapes the lines the program writes there. The figures below come from the U.S. Census Bureau.
Statewide 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.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Where Michigan’s homeowners hold their equity — market by market.
Six Michigan markets, each with its own equity picture and its own guide. The tier ladder and the ceilings do not change from one to the next; the values, the balances, and the typical lines do.
Detroit
Detroit holds one of the largest pools of owner households among Lendmire’s Michigan markets — roughly 129,895, about 50% of households — a metropolitan market where a home equity line is an everyday tool for an established owner. Census context: median value near $83,900, median household income near $39,938, population near 639K.
Grand Rapids
Grand Rapids holds one of the largest pools of owner households among Lendmire’s Michigan markets — roughly 43,351, about 54% of households — a metropolitan market where a home equity line is an everyday tool for an established owner. Census context: median value near $244,500, median household income near $69,108, population near 199K.
Sterling Heights
In Sterling Heights, owner households number near 39,206, about 76% of households, and the metropolitan market there produces a steady flow of equity lines sized by tier. Census context: median value near $274,300, median household income near $79,909, population near 134K.
Warren
In Warren, owner households number near 38,922, about 71% of households, and the metropolitan market there produces a steady flow of equity lines sized by tier. Census context: median value near $193,400, median household income near $64,016, population near 138K.
Livonia
In Livonia, owner households number near 33,424, about 87% of households, and the metropolitan market there produces a steady flow of equity lines sized by tier. Census context: median value near $281,100, median household income near $98,460, population near 94K.
Lansing
Lansing ranks sixth by owner households among Lendmire’s Michigan markets — roughly 27,771, about 54% of households — a metropolitan market where a home equity line is an everyday tool for an established owner. Census context: median value near $128,700, median household income near $54,382, population near 113K.
Statewide, the program rules are the same in every Michigan market: the tier ladder, the combined loan-to-value ceilings, the valuation path, the property list, and the vesting rules. Where Michigan adds a rule of its own, this guide and every city guide carry it.
Four ways Michigan homeowners put a home equity line to work.
A good use of a HELOC is one that matches its shape: a need that is staged, repeated, or uncertain in size. Four common Michigan uses follow.
Bridge the move between homes
Sequencing matters: a line is opened on the Michigan home while the owner still lives there and before it is listed, then drawn for the next purchase and repaid at the sale. Listing first takes the home outside the higher-leverage program, and outside both programs in some states.
Consolidate higher-cost debt
Card balances and personal loans carry their own costs and payments; a Michigan owner with equity can draw on the line to retire them and manage one secured balance instead of several unsecured ones. The trade is that the home now secures the debt.
Cover a large planned expense
When the expense is known and the timing is near, a Michigan 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.
Repay and draw again as needs change
The line revolves through the draw period: a Michigan 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.
Estimate your Michigan home’s available credit line before requesting a quote.
The calculator applies the program tables to a Michigan scenario: enter the home’s value and the balance secured by it, pick the credit tier and the occupancy, and it returns the available line, the equity position, the combined loan-to-value before and after the draw, the minimum draw at closing, and the valuation path. Nothing here is a rate or a payment; those come in writing from a licensed loan officer.

Every field is editable.
Illustrative estimate only — not a credit decision, approval, quote, or commitment to lend.

Same equity, four very different ways to use it.
A Michigan 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.
Replaces the first mortgage with a larger one and hands over the difference in cash at closing. One payment, one lien, a fixed amount, but the entire mortgage is re-written, which matters when the existing first mortgage carries terms worth keeping. 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 Michigan need is a single known amount, such as one contractor bid, and the owner wants a fixed schedule from day one.
Credit cards and personal loans secure nothing and ask nothing of the home, which is their advantage, and they cost more and cap lower, which is their limit. For a small or short need they can be the right tool; for equity-sized needs they rarely are.
What to prepare for a Michigan scenario review.
A home equity line is verified electronically wherever it can be; the items below are what a Michigan scenario review typically draws on.
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.
Details that can change the line.
Most surprises on a Michigan line trace back to one of these: a tier that landed differently than expected, a valuation under the owner’s estimate, a vesting issue, or a state rule.
Use these checks to keep the Michigan 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: lines above the threshold take a full appraisal and a reduced ceiling.
- Know the history: recent housing lates close the program; the lookback runs longer at the lower tiers.
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 Michigan line can change size without the value or the balance moving at all.
Automated valuation on most lines, appraisal on the largest
Most Michigan 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.
Lien position and the first mortgage
A line usually sits in second position behind the first mortgage, and that first mortgage must be a conventional structure: no negative amortization, no balloon, no reverse-mortgage features. A Michigan home owned free and clear can take the line in first position.
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 Michigan 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.
From a Michigan prequalification to a funded line.
Four steps, most of them electronic: the scenario, the prequalification, the verification and valuation, and the closing. Here is the Michigan path.
Scenario review
Start with the value, the balance, the tier, and the occupancy. A Lendmire loan officer sizes the Michigan 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 Michigan property, the identity, the tier, and the valuation, then presents an offer. Accepting it is what triggers the hard credit pull.
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 Michigan 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.
Lendmire is never the lender. It is the broker that sizes the Michigan line against two wholesale programs, matches the structure to the use, and keeps the first mortgage out of the conversation unless a refinance is actually the better answer.
Two programs, the stronger cell quoted
A single program is a single answer; two programs are a choice. The Michigan 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
Lendmire sizes the Michigan line to the purpose, not to the maximum the ladder allows: the minimum draw at closing, the repayment runway, and the ratio all argue for a line that fits the job.
Licensed, consumer-purpose, in writing
The program figures on this page come from one guideline source; the terms for a specific Michigan file come from a licensed loan officer, in writing, after the review. Lendmire is a broker, never the lender.

Michigan HELOC FAQs
Plain answers to the questions Michigan 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 Michigan?
Start from the value, apply the ceiling for your tier, subtract the mortgage balance, and cap at the program maximum. A Michigan owner with a modest first mortgage and a strong tier reaches the largest lines; a recent purchase at a lower tier has less room.
What credit score do I need for a HELOC?
Scores from the program floor are eligible on a primary residence. The tier matters as much as eligibility, since it decides the ceiling and the cap; and the lender’s own report decides the tier, not an app or a self-pulled score.
Do I need an appraisal for a HELOC?
It depends on the size of the line. Up to the automated-valuation threshold the model’s value stands, sometimes with a secondary valuation at higher leverage; above it an appraiser values the Michigan home and that figure governs.
How do the draw period and the repayment period work?
Two phases: a draw period of interest-only payments on whatever is borrowed, then a repayment period in which the balance amortizes. The two wholesale programs differ in length, trading a shorter draw and faster repayment for more leverage, or a longer draw and runway for less.
How is my debt-to-income ratio calculated on a HELOC?
Liabilities plus the interest-only payment on the maximum draw, over total verified income. The ratio is one of the few places where the tier changes the rule rather than the figure: the cap on the ratio is lower at the lower tiers.
How is income verified for a HELOC?
Electronically first: a payroll-database match or a borrower-permissioned connection to the employer or bank account. Documents, including pay stubs, W-2s, and tax returns, are the fallback. Self-employed owners connect personal and business accounts for a deposit and trend analysis, or provide returns.
Can I get a HELOC on a home I am about to sell?
Only if the line comes first. A recent or active listing makes the Michigan home ineligible for the higher-leverage program everywhere, and for the longer-runway program in some states, so a buy-before-you-sell plan funds the line before the home goes on the market.
My rental is in an LLC. Can it get a HELOC?
No; entity vesting is outside both programs. A Michigan investor can move the rental into individual names before closing, or look at an investor cash-out refinance built for entity-held property.
Can I open a HELOC and not use it right away?
A reserve is a common use, with one caveat: the minimum closing draw funds whether or not you need it yet. Size the line to the closing draw you are willing to take, and hold the remainder for later.
Size a Michigan line, then get the terms in writing.
Ready when you are: a Michigan review sizes the line, settles the structure, and delivers the written terms. Nothing on this page is a commitment to lend.
