The Quick Read: A home equity line is secured by a property you already own, so the lenders that write one for a build are lending against that property’s equity, not against the new house. The line can carry a build on its own only when its limit covers the whole project; otherwise it can serve as the equity behind a separate construction loan. The lenders that write these lines, and the terms they use, depend on the occupancy of the property securing the line, the credit profile, and the combined loan-to-value.
- The line is sized to current equity, not to what the finished home will be worth.
- Lendmire is a mortgage broker, so the answer to which bank fits is a program match, not a single name.
- Investment-property lines in the network top out at 70% CLTV, and primary-residence lines reach higher only with stronger credit.
- A finished rental can later move to a DSCR loan, which is qualified on the property’s rent.
Can a HELOC Really Pay for a New Build?
A HELOC can fund a build, but only as a source of cash. It is not a construction loan. A construction loan releases money in stages as the project hits milestones. A HELOC hands you a revolving limit tied to equity in a home you own today.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
That difference shapes everything else. The lender looks at the collateral property, subtracts what is owed on it, and lends a portion of what remains. Land, permits, site work, framing, and contingency all come out of that one limit. If the limit is smaller than the budget, the line cannot carry the project alone.
Investors usually use a line in one of two ways. The first is to fund the entire build from the line, which only works when the line is large enough. The second is to use the line as the equity or down payment behind a separate construction loan.
Lendmire approaches the question from the borrower’s side rather than the bank’s. The brokerage shops a network of wholesale HELOC lenders and matches the scenario to the program that fits. It does not lend and does not rank institutions.
Key Terms Defined
HELOC: An open-end line of credit secured by a home, which you can draw on repeatedly up to a limit.
CLTV: Combined loan-to-value, which adds the new line to existing liens and divides by the property’s value.
Draw period: The stretch of years when you can borrow from the line, usually with interest-only payments.
Repayment period: The years after the draw ends, when borrowing stops and the balance amortizes.
DTI: Debt-to-income ratio, which compares monthly debts to monthly income.
DSCR: Debt service coverage ratio, which divides a rental’s monthly rent by its monthly principal, interest, taxes, insurance, and any HOA dues.
Vesting: The way title is held, such as in an individual’s name or a revocable trust.
How Underwriting Treats the Line, Step by Step
A bank reviewing a line for a build does not underwrite the build. It underwrites the collateral and the borrower. Here is the sequence across the network’s wholesale programs.
1. Identify the collateral. The line attaches to one property with equity. That may be a primary residence, a second home, or an investment property. The occupancy decides the ceiling, the credit minimum, and the maximum line size.
2. Value the property. Lines at or below $500,000 ordinarily run automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation. Every line above $500,000 needs a full appraisal, and a borrower can ask for one in any case.
3. Count existing liens. The line can sit in first or second lien position. Combined balances are measured against the value, and that percentage is the CLTV.
4. Check credit. The program floor is 600. A single-bureau score keyed to the primary wage earner drives the tier, and the report cannot be more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal.
5. Run debt-to-income. The maximum is 50%, and it drops to 45% for credit profiles from 600 to 679. A ratio above 45% requires a 680 score at minimum. The payment used is interest-only on the maximum draw, not on what you plan to borrow first.
6. Confirm title and property type. Title must sit with the individual borrower or a revocable living trust. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial or agricultural properties are not.
7. Check exposure. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
The purpose of the funds is not the main driver of the decision. The collateral, the credit, and the combined leverage are. The line stays in place whether the money goes to a roof, a lot, or a framing crew.
What the Network’s Programs Look Like
The ceilings depend on occupancy, so one number never fits every borrower. Lendmire places these lines through two select wholesale programs. One uses a 3-year interest-only draw followed by a 17-year repayment. The other, the 5-year-draw structure, uses a 5-year draw followed by a 25-year repayment. Pricing floats across both the draw and the repayment period and never converts to fixed. Every figure is subject to lender guidelines and full file review.
| Occupancy | Top CLTV | Credit and line size |
|---|---|---|
| Primary residence | 90% | 720+, up to $500,000 |
| Primary residence | 75% | 700+ (720 on the longer-runway program), up to $750,000 |
| Second home | 90% | 720+, up to $500,000 |
| Investment property | 70% | 700+, up to $500,000 |
Lower credit tiers step the ceiling down. A primary residence at 640 tops out at 80% CLTV on lines up to $500,000, and at 620 it falls to 70% on lines up to $400,000. Investment lines have a 700 minimum and run the 5-year draw and 25-year repayment structure only.
Line size runs from $25,000 to $750,000. A line above $500,000 is for primary residences only. It needs a score of 700 or better (720 on the 5-year-draw structure), caps at 75% CLTV, and requires a full appraisal.
At least 75% of the line is drawn at closing. That matters for a build. This is not a line you open and leave idle until the foundation is poured. Interest accrues on most of the balance from the start, so the build budget and the draw schedule need to be planned together.
HELOC availability covers Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C.
Where the General Rule Breaks
Several edge cases change the answer. These are the ones that come up on build files.
Land you own outright. A lender can sometimes write a line against land that carries no mortgage. As Yahoo Finance explains, such lines are limited to the portion you own free and clear. The limit follows the land’s value, which is usually far below the cost of the finished house. The network’s programs are written for residential properties with a dwelling, so a vacant lot is not the usual collateral.
A property still under construction. A line is generally not available on a home that is still being built. The equity has to exist in a completed property today.
An LLC-owned property. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on these lines, per lender program requirements. A property already deeded to an LLC needs a vesting change first. A DSCR cash-out is the other route for those files.
An investment property as collateral. The investment line is real, but it is the tightest tier: 700 minimum credit, 70% CLTV, and a $500,000 cap. Using it to build means the existing rental carries the risk.
A home listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. Selling the old home and borrowing against it at the same time does not work in those states.
Ineligible structures. Manufactured homes, log homes, and barndominiums are not eligible collateral for the lines described here, and they are not offered under the network’s DSCR programs either.
The Risk Side: Variable Pricing and the End of the Draw
The CFPB describes a HELOC as a line you can draw on during a draw period, then repay over a set schedule once borrowing ends. It also warns that falling behind could cost you the home that secures the line. For a builder, that means the existing house carries the construction risk.
Underwriting qualifies the borrower on the interest-only payment at the maximum draw, but the payments you actually make during the draw follow the amount you have borrowed. The CFPB notes that payments are often significantly higher once repayment starts. A build that runs late can collide with the end of the draw period. The CFPB’s HELOC booklet also shows that the line is a fraction of equity, not of project cost, which is why budgeting from the line down matters more than budgeting from the dream house up.
There is no lender draw inspection on a HELOC. A construction lender watches milestones. With a line, the borrower manages cost overruns, contractor payments, and timing alone.
How the Three Pieces Compare
| Feature | HELOC on existing home | Construction loan | DSCR on finished rental |
|---|---|---|---|
| Collateral | Home you already own | The project itself | The completed property |
| Sized to | Existing equity | Plans and project value | Rent versus debt service |
| Funds released | Mostly at closing here | In stages | At closing |
| Personal DTI | Counts | Counts | Qualified on property rent |
A HELOC does not provide a permanent mortgage on the new home. The borrower still needs takeout financing when the build ends.
Where a DSCR Loan Fits After the Build
For an investor building to rent, the long-term loan usually comes after the keys. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The network’s complete DSCR loans guide walks through how that works.
On a purchase, most files land at 75% to 80% LTV, and select high-leverage programs reach 85% with roughly a 700+ score. A cash-out refinance on the finished rental tops out around 75% LTV, with about 6 months of seasoning as the common expectation. That seasoning is why a build finished last month does not usually refinance right away.
Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation.
Reserves vary by lender, leverage, loan size, and transaction type. Commonly they sit around 6 months of PITIA, with larger loans stepping up. Credit floors start at 620 in parts of the network, with most programs wanting around 660.
Which Bank or Program Fits Your Build?
The best program for your situation depends on four things: which property will secure the line, your credit tier, your combined leverage, and how much of the budget the line has to cover.
Some patterns hold across the network. A primary residence with strong credit has the most room, because it reaches the highest CLTV tiers and the largest lines. A second home sits in the middle. An investment property carries the lowest ceiling, so it rarely funds a full build alone.
Foreclosure history splits the programs. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4 years. The other declines that history regardless of age. That is one reason a broker shopping both matters. A single bank sees one set of overlays, and a broker sees several.
What the Investor Decision Looks Like
Start with the budget, not the line. Total the land, site work, construction, fees, and a contingency cushion. Then compare that total to what the collateral property can support at its ceiling. If the gap is large, the line is the equity layer and something else carries the build.
Next, decide who bears the risk. A primary-residence line puts the family home behind the project. An investment-property line puts a rental behind it. Neither is neutral.
Then plan the exit. If the finished property will be a rental, a DSCR loan is the usual takeout, and its terms depend on rent coverage, credit, and seasoning. Run both layers together before drawing a dollar.
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals.
Frequently Asked Questions
Can a HELOC be secured by the home I am building?
No. The line attaches to a property that already has equity. The new home does not exist as collateral until it is finished, and by then you would need a different loan.
Can I use a HELOC on a rental to build another property?
It is possible on an investment property, but the terms are the tightest tier in the network: a 700 minimum credit score, a 70% CLTV ceiling, and a $500,000 maximum line. Title must be held by an individual or a revocable living trust, so an LLC-owned rental needs a vesting change first.
What happens to the HELOC if I sell the old home before the build ends?
The line is secured by that property, so a sale pays it off. It stops being a funding source for the build. In several states, a property listed for sale within the past 60 days is not eligible for a new line at all.
Does a HELOC draw hurt my chances of a later construction or conventional loan?
It can, because a draw raises your personal debt-to-income ratio, and a construction lender will count it. A DSCR loan on a finished rental is different, because it is reviewed on the property’s rent.
How much of the line do I have to draw at closing?
On both of the network’s wholesale programs, at least 75% of the line is drawn at closing. The minimum draw after closing is $1,000 where a program states one. Plan the build budget around that, since interest accrues on most of the balance from the start.
