The Quick Read: Wait until the build is finished, the construction loan has converted or been paid off, the title is clean, and the lender’s seasoning period is met. Then apply for a standalone line that sits behind the permanent first mortgage, or in first position if no mortgage remains.
- A HELOC (home equity line of credit) is a revolving line on a finished home. It cannot stand in for the construction loan.
- No special product exists for this situation. Once the loan converts, the house is an ordinary completed property.
- A HELOC is judged mainly on you: credit, debt-to-income, combined leverage, and the as-built value.
- Across Lendmire’s wholesale network, investment-property lines cap at 70% CLTV with a 700 minimum credit profile, subject to lender guidelines.
- LLC title is not allowed on these lines, and many ground-up rentals are titled that way.
Plenty of investors build a rental from the ground up and then ask the natural question. The builder is paid, the certificate of occupancy is in hand, and the house has equity. Can that equity fund the next project?
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.
Often it can. The path just has an order of operations, and skipping a step is the usual reason a file stalls.
Why Can’t You Open One While the House Is Still Going Up?
A lender wants a finished, insurable home with a stable first lien before it adds a second claim. During construction the collateral is a half-built structure, the title carries open work, and the existing loan is still drawing. A line of credit on that foundation is a poor risk.
Think about what a lender actually sees mid-build. The value on paper is a projection. Contractors may still have lien rights. The construction lender holds a loan that has not yet turned into permanent financing. A second-lien lender cannot tell how much will end up owed or what the house will appraise for.
The result is simple. A HELOC does not replace a construction loan, and you cannot switch to one halfway through. A construction loan pays out in stages and then converts into a mortgage. A HELOC is a revolving line you open on a home that already exists. They are two tools for two different stages. Lendmire’s piece Can You Open a HELOC on a Newly Built Home? covers the general question.
What Has to Happen First?
The construction loan must become permanent financing, or be paid off, before a HELOC lender will look at the file. How that happens depends on how the build was financed.
| Factor | One-close loan | Two-close loan |
|---|---|---|
| Structure | Converts to a mortgage | Separate permanent loan |
| Who acts at completion | Same lender converts | You apply for new loan |
| HELOC timing | After conversion | After new loan funds |
| Extra qualifying step | Possible credit refresh | Full new application |
Once the permanent first mortgage is in place, the one-close versus two-close distinction stops mattering. A HELOC lender cares about the permanent first lien, the certificate of occupancy, the title, and how long you have owned the home. It does not care which path produced the loan.
If you paid the construction loan off with cash or other funds, there may be no first mortgage at all. In that case a standalone line can sit in first position. The related question of selling later is covered in Lendmire’s piece Can You Sell Your Home While a HELOC Is Open and Drawn?.
What Does a Lender Want to See Before You Apply?
Lenders want proof that the build is truly finished and paid for. Gather these items before you submit anything. A missing lien release is a common reason a new-build file sits unanswered.
| Item | Why the lender cares | How you document it |
|---|---|---|
| Certificate of occupancy | Home is legally habitable | Copy from the local building office |
| Lien waivers | No open contractor claims | Signed by builder and subs |
| Final draw statement | Build is fully paid | Construction lender’s payoff record |
| Updated title | Clean lien position | Title company search |
| Homeowner’s policy | Builder’s risk has ended | Permanent policy declarations page |
| Permanent mortgage statement | First lien is stable | Latest statement |
For a picture of what “complete” means, Fannie Mae’s guidance on single-closing construction-to-permanent loans lists a completion report (Form 1004D), lien waivers, and a certificate of occupancy. That guidance governs agency-backed loans, not these lines. It is still a useful checklist, because any second-lien lender wants the same evidence that the work is done and paid for.
How Do Lenders Value a Brand-New Home?
They value it on what it is worth today, not on what you spent. A new build has few direct comparable sales, so the valuation can land above or below your total cost. The appraisal from your construction loan does not carry over as the number for the new line.
Across the network, lines of $500,000 or less ordinarily run an automated valuation instead of a traditional appraisal. A higher combined loan-to-value (CLTV, meaning all liens added together divided by value) may call for a secondary valuation. A full appraisal is required on every line above $500,000, and you can request one on any line. On a new build with thin comps, asking for the full appraisal can make sense.
Here is how the equity math works, using modeled percentages instead of dollars. Say the as-built value comes in at 100% and the first mortgage balance equals 55% of it.
- On an investment property capped at 70% CLTV, the line has room for about 15% of value.
- On a primary residence at 720 or better, a 90% CLTV ceiling leaves up to 35% of value, though the line itself cannot exceed $500,000 at that tier.
Those are modeled assumptions, not a quote. If your build ran over budget and the home appraises near cost, the room can shrink fast. A lender also may not credit value above the price you paid for a period of time. A poster on a myFICO forum thread describes exactly that: financing available right after closing, but with value capped near the purchase price for several months. That account is anecdotal, yet it matches how many lenders behave.
Step by Step: From Final Draw to Funded Line
Here is the sequence that works on most files.
1. Finish and pay for the build. Make the final draw, collect lien waivers, and obtain the certificate of occupancy.
2. Convert or refinance the construction loan. Wait until a permanent first mortgage is in place, or the loan is paid off.
3. Confirm the seasoning clock. Seasoning is the waiting period a lender wants between buying or finishing a home and lending against it. It is lender policy, not law. The clock typically runs from the recorded deed date, so ask whether it starts at the lot purchase, the construction closing, or the conversion.
4. Pull your documents. Collect the checklist above, plus a current credit review and proof of occupancy type.
5. Apply and get a valuation. The lender checks credit, debt-to-income, CLTV, and the as-built value.
6. Review the terms before you sign. Look at the draw period, the repayment period, and how much you must draw at closing.
7. Close and draw. After closing, you can draw on the line as the terms allow.
Underwriting on this product is borrower-based. NerdWallet’s explainer on investment-property HELOCs reports debt-to-income limits of roughly 40–50% across the broader market. On Lendmire’s network the maximum is 50%, and a ratio above 45% requires a credit profile of 680 or better. Lenders review your file on the interest-only payment calculated on the maximum draw, so a bigger line can hurt your ratio even if you never use it all.
What Do the Network’s Lines Actually Look Like?
The ceiling depends on how the home is used, so one number never fits everyone. Lendmire brokers HELOCs through select wholesale partners and is never the lender. Every figure below is subject to lender guidelines and full file review.
| Occupancy | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Primary residence | 90% (at 720+) | 600 floor | $750,000 |
| Second home | 90% (at 720+) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
The primary-residence ceiling is tiered. At 720 or better, 90% CLTV applies only up to $500,000. Above that, 75% CLTV is the cap, up to $750,000. A line above $500,000 is for primary residences only and requires a 700 credit profile or better (720 on the longer-runway program, the 5-year draw structure covered below), plus a full appraisal.
Two draw structures exist across the network. A higher-leverage program uses a 3-year interest-only draw followed by a 17-year repayment. The longer-runway program uses a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment structure only.
On both, at least 75% of the line is drawn at closing. Pricing floats during the draw and repayment periods and never converts to fixed. For comparison, NerdWallet describes a typical market structure as a 10-year draw followed by repayment of up to about 20 years. Network terms differ, so compare the structure before you compare anything else.
Availability is narrower than the DSCR side of the business. Lendmire’s HELOC placements cover 16 full-service states, while its DSCR investor loans reach 41 markets, including Washington, D.C.
Where Does the General Rule Break?
Most of the surprises sit in the property, the title, and the lender. Check each of these early.
Your home is held in an LLC. Many investors put a ground-up build in an LLC for the construction loan. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Title must sit with you personally or in a revocable living trust. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to program eligibility.
The home is a rental. A lender sees more default risk on a rental than on a primary residence. NerdWallet notes that this shrinks the lender pool and tightens borrowing limits. On Lendmire’s network, an investment line requires 700 or better and tops out at 70% CLTV and a $500,000 line.
The build type is not eligible. Manufactured homes, log homes, condotels, and co-ops are not eligible on these lines. Modular factory-built homes are eligible on the longer-runway program only. Single-family homes, 2-4 unit properties (640 minimum on the longer-runway program), PUDs, townhomes, and condominiums are eligible, including non-warrantable condos.
Your credit sits below the tier. The floor is 600, and a score under 640 limits you to single-family primary residences with a clean 12-month housing history on the longer-runway program. Second homes floor at 640 and investment properties at 700.
You have a derogatory event. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On primary residences and second homes, one program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines that history entirely.
You hold a lot of exposure. A borrower is limited to three lines, and one with more than 15 financed properties is not eligible.
The lender waives seasoning. Some portfolio lenders and credit unions will shorten or skip the wait for strong borrowers. Do not count on it. Get the commitment in writing before you plan around it.
What If You Need Money Before the Home Is Finished?
A HELOC will not solve a mid-build cash gap on the house being built. The builder or construction lender still holds the project. Your realistic options are a change order or loan-amount increase with the construction lender, a contingency built into the original budget, or funds from another property.
An equity line against a different home you own is a separate transaction. That other home must meet the program’s occupancy, credit, and title rules on its own. Any draw also shows up in bank statements and in the source-of-funds review of a later loan. It adds debt to your profile even though it does not change a future DSCR ratio.
A borrowed line is debt, not savings. Lenders generally do not count it as reserves.
HELOC or DSCR Cash-Out on a Ground-Up Rental?
For a finished rental, the real decision is usually between a HELOC and a DSCR cash-out refinance. The two are underwritten on different things. A HELOC looks at you. A DSCR loan looks at the property, and it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide explains the full mechanics.
A HELOC leaves your first mortgage in place. That helps if the permanent loan has terms worth keeping. A DSCR cash-out refinance replaces the first mortgage entirely. On a standard rental, cash-out tops out around 75% LTV across most of the network (70% on short-term-rental collateral), and about 6 months of seasoning is the common expectation. Every figure here varies by lender and program: guidelines, property type, leverage, and credit profile all apply.
Coverage matters on that side. A 1.00 coverage ratio is where many select programs start. 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 the ratio compares rent to the principal, interest, taxes, insurance, and any association dues only. Repairs, vacancy, management, and capital expenses sit outside it.
A practical way to choose:
- Pick the HELOC when your personal profile is strong, you want to keep the first mortgage, and the title is in your name.
- Pick the DSCR cash-out when the property is in an LLC, your debt-to-income is tight, or the rent carries the file better than your income does.
- Use the line sparingly if you plan to refinance the first mortgage soon, because a second lien adds a step to that refinance.
Brokers see these ground-up files regularly. The deals that go smoothly usually have lien waivers, the certificate of occupancy, and the permanent mortgage statement collected before the application starts. The ones that stall often discover an open lien or an LLC deed after the lender has already ordered a valuation.
Key Terms Defined
HELOC. A home equity line of credit is a revolving line you borrow against a property’s equity. The CFPB describes it as an open-end line you can draw on repeatedly, with a draw period that can last 10 years.
CLTV. Combined loan-to-value adds every loan secured by the home and divides the total by its value.
Seasoning. This is the waiting period a lender wants after you buy or finish a home before it lends against it.
First lien and second lien. A lien is a legal claim on a property. The first lien gets paid first, and a second lien sits behind it.
Certificate of occupancy. This local document confirms a new home is safe and legal to live in.
Lien waiver. A contractor signs this to confirm they have been paid and give up their claim on the property.
One-close and two-close. A one-close construction loan converts to a permanent mortgage. A two-close build uses a separate permanent loan.
DSCR. The debt service coverage ratio divides a property’s monthly rent by its monthly payment of principal, interest, taxes, insurance, and any association dues.
Frequently Asked Questions
Can I get a HELOC while my house is still being built?
Not on the house under construction. The collateral is unfinished, the title has open work, and the construction loan is still active. Lenders that write lines in this phase are conservative and base value on the land. Wait for completion and conversion, then apply on the finished home.
Does the seasoning wait start when I buy the lot or when the build ends?
It depends on the lender, so ask directly. The clock typically runs from the recorded deed date, which may be the lot purchase. Some lenders instead count from the construction closing or the permanent loan. Get the answer before you apply so you do not pay for a valuation you cannot use.
Will my construction appraisal work for the HELOC?
Usually not. Lenders set value on the home as it stands for the new line. On the network, lines of $500,000 or less ordinarily use an automated valuation, and a full appraisal is required above that size. You can request a full appraisal on any line, which helps when a new build has few comparable sales.
What if my home is titled in an LLC?
These lines cannot be placed on LLC, corporate, partnership, or land-trust title. You would need to move title to yourself or a revocable living trust first, depending on your situation. A DSCR cash-out refinance is the other route, subject to program eligibility.
Is a HELOC the same as a DSCR loan?
No. A HELOC is underwritten on your credit, income ratios, and CLTV. A DSCR loan is reviewed primarily on whether the property’s rent covers its payment. The two can solve the same cash need, but they sit on very different qualification tests.
Next Steps
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. Run the illustrative calculator for a first read, then bring your lien status and title to a broker who can compare more than one lender.
A finished ground-up build is an unusually clean piece of collateral once the liens are released, which makes the paperwork, not the property, the thing most worth getting right first.
