The Quick Read: Only a small group of lenders write a line of credit secured by a rental you already own, and the money can pay for a ground-up build because the existing property, not the new one, is the collateral, though an investment line in Lendmire’s wholesale network tops out at 70% CLTV and $500,000, subject to lender guidelines.
- The collateral is a property you already own, and the unbuilt project plays no part in securing the line.
- On an investment property, the network ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on these lines.
- At least 75% of the line is drawn at closing, so it works as a lump-sum equity tool more than a staged construction draw.
- The usual exit is a DSCR cash-out refinance once the new property is built, rented and stable.
Which Banks and Lenders Write These Lines?
Very few do, and the list changes. Big banks rarely advertise an investment-property line, and Experian describes the product as less common, harder to qualify for and not offered by every lender. Taxstra adds that most national banks do not offer it at all, while some regional banks and credit unions run investor programs.
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 is why a named list of banks goes stale. A bank that wrote these lines last year may have paused them this year. Underwriters also change the rules at the portfolio level without announcement.
Lendmire does not lend. It is a mortgage broker that shops several wholesale HELOC lenders and matches the property, equity, credit profile and goals to a program. The lenders that write this product for your file depend on your state, the property type, how title is held and how much leverage you need.
Two practical points help the search.
1. Ask for a line of credit secured by investment property rather than a home equity line. Some lenders decline the word HELOC outright even when they offer a similar product.
2. Ask in writing whether the lender allows non-owner-occupied collateral, what the CLTV cap is, and whether LLC title is accepted.
Availability through the network is narrower than the DSCR footprint. Lendmire’s DSCR investor programs run across 41 markets, including Washington, D.C. The HELOC programs are limited to 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA.
How Underwriting Treats an Investment Property Line, Step by Step
The mechanics are simple on paper. Each step has a place where files stall.
1. Collateral. The line attaches to a property you already own. Eligible types include single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.
2. Vesting. Title must be held by you as an individual or by an inter vivos revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan, and it is the step investors forget.
3. Equity sizing. The lender adds every lien on the property, divides by value, and tests the result against a CLTV cap. On an investment property, the cap in the network is 70% CLTV. The line is what remains after your existing mortgage. The CFPB HELOC booklet describes the same logic: a percentage of appraised value, less what you owe, along with a review of your ability to repay.
4. Credit. Investment lines require a 700 minimum. A 720 score and a 700 score both reach 70% CLTV, so a higher score buys no extra leverage here. It only keeps the file eligible. Programs run a single-bureau score keyed to the primary wage earner, the report can be no more than 90 days old at closing, and rescores are not allowed.
5. Debt-to-income. The maximum is 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to draw. A large line therefore stresses DTI even if you intend to draw little.
6. Valuation. Full appraisals begin only above $500,000, and an investment line never reaches that size. So these lines sit in the automated-valuation lane and commonly close with no traditional appraisal. A borrower may still ask for a full appraisal.
7. Lien position. The line can sit in first or second position. That matters if the same property also carries a mortgage you intend to keep.
8. Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure seasons at 7 years and a deed-in-lieu, pre-foreclosure or short sale at 4.
9. Exposure limits. A borrower is limited to three lines, and a borrower with more than 15 financed properties is not eligible.
All of this is subject to lender guidelines and full file review, and none of it is a commitment to lend.
The 75% Draw at Closing Changes How You Use It for a Build
This is the detail that matters most for construction. At least 75% of the line is drawn at closing. Later draws carry a minimum, typically $1,000 and higher in Texas, where stated.
A construction loan works the other way. It pays out in installments tied to milestones, with inspections along the way. An investment HELOC has no lender-run draw schedule and no inspections. Once it closes, you control the spending, and the lender generally does not restrict what the proceeds pay for.
That freedom has a cost. Most of the line is drawn and accruing interest on day one. A new build produces no rent while it is under construction. Nothing covers the carry except your own cash flow.
The structure is also long-dated and floating. The investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both periods and never converts to fixed. The CFPB notes that payments on lines like this often jump once repayment begins, and some plans require a minimum draw. A build that runs long can push you toward that jump before the property is leased.
Run the carry as a sizing test. Plan for the whole construction period as if the line were fully drawn, with no rental income offsetting it.
HELOC, Construction Loan, Cash-Out or Closed-End Second?
The right tool depends on where the equity sits and how predictable the build budget is. A rough comparison:
| Option | Collateral | Fit for a new build |
|---|---|---|
| Investment property line | Existing rental | Flexible, but mostly drawn up front |
| Construction loan | The project itself | Built for ground-up work, milestone draws |
| DSCR cash-out refinance | Existing or stabilized rental | Equity access or takeout, not construction money |
| Closed-end second | Existing property | Fits a fixed budget, no repeat draws |
A few notes on each.
- Construction loan. If you have little equity elsewhere, this is usually the workable path, because the project itself secures the money.
- DSCR cash-out refinance. It reads the rent against the full payment instead of your personal DTI. A DSCR loan generally reads a finished, rentable property and does not fund active construction.
- Closed-end second. It fits a fixed budget but cannot be redrawn, which is a poor match for costs that move.
Which one fits depends on your equity, your build budget and your timeline.
Where the General Rule Breaks
The basic answer is that a line on an existing rental can fund a build. These cases change it.
The build is on the property that secures the line. If a construction loan is open on the same property, lien order becomes the problem. A construction lender usually wants first position, and a line placed behind a still-drawing construction loan is hard to place. The cleaner structure uses separate properties: the line secured by the rental you own, the build funded from the proceeds.
The rental is held in an LLC. Many investors hold rentals in entities. These lines cannot take LLC title, so you either move title to yourself or a revocable trust, or you skip the line and use a DSCR cash-out refinance. Subject to program terms, DSCR cash-out refinances can be written to entities, which is why the DSCR route often fits portfolio investors better.
The line you need is larger than $500,000. An investment line cannot exceed $500,000. Lines up to $750,000 exist, but only on a primary residence, with at least a 700 credit profile (720 on the longer-runway structure), a 75% CLTV cap and a full appraisal. Putting a primary-residence line to work on a rental build shifts the collateral risk to your home. The CFPB booklet warns that the home secures the line.
The property is listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX and WA.
The property is in a state the network does not cover. HELOC programs run in 16 states only. Outside them, the options are a DSCR cash-out refinance or a local portfolio lender.
You have thin equity. At 70% CLTV on an investment property, the line is only what remains after your existing mortgage. If the first lien already uses most of that room, no line will fund much of a build.
Credit is between 600 and 699. Investment lines floor at 700 with no tier beneath it. A 700 minimum cannot be offset by extra equity.
The Takeout: Retiring the Line With a DSCR Loan
A new build with no rent cannot support its own debt. The investor needs an exit before drawing a dollar.
The usual sequence has three steps. The line pays for the build. The investor then leases the finished property and lets it stabilize. A DSCR cash-out refinance then replaces the line with fixed, long-term debt.
Across the wholesale network, most DSCR cash-out files top out around 75% LTV on standard long-term rentals. About 6 months of seasoning is the common expectation. Credit expectations vary by lender, and a higher score opens the strongest leverage tiers. Reserves vary by lender, leverage, loan size and transaction type, and commonly sit around 6 months of PITIA.
Some select programs begin at a 1.00 DSCR. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
A ratio of 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capex sit outside the calculation. A new build also has to prove it can rent before a lender will count the rent.
Consider an investor whose finished property leases to roughly 1.2x coverage on the full payment, with leverage inside the cash-out cap. That file can retire the line, subject to lender guidelines and property review. If the property leases at 0.95x, the investor looks at select-lender sub-1.00 options, with lower leverage and adjusted terms. The point of the plan is to finish lease-up and stabilize the property before the line’s repayment period begins.
The complete DSCR loans guide covers how coverage is calculated and which documents lenders ask for.
What the Decision Looks Like in Practice
Consider a rental owner with strong equity, a 700-plus score, personal or revocable-trust title and a budget that fits under $500,000. A line at up to 70% CLTV can fund part of a build. The investor should size the carry for the entire construction period, with the line mostly drawn from day one.
Now picture an investor with a rental in an LLC and a build costing more than the available equity. The line is the wrong tool. A construction loan on the build itself, and a DSCR cash-out refinance as the takeout, is the cleaner structure.
A third investor has good credit and little equity. A line may not produce enough money, and a closed-end option or construction loan may fit better.
Questions worth putting to any lender before applying:
- Does the lender allow non-owner-occupied collateral in my state?
- What is the CLTV cap, and how is value determined?
- Can the property be vested in an LLC, or must it sit in my name?
- How much of the line is drawn at closing?
- What happens when the draw period ends?
- Does pricing float, and can it convert to fixed?
Key Terms Defined
HELOC: A revolving line of credit secured by property you own, with a draw period followed by repayment.
CLTV: Combined loan-to-value, which adds every lien on the property and divides the total by its value.
Draw period: The stretch when you can borrow from the line, often with interest-only payments.
Construction draw: A staged payout from a construction loan, tied to build milestones and usually inspected.
DSCR: Debt service coverage ratio, which compares a property’s rent to its full monthly obligation of principal, interest, taxes, insurance and any HOA dues.
Vesting: The legal form in which title to a property is held, such as an individual, a revocable trust or an LLC.
Frequently Asked Questions
Can I use a home equity line on a rental to fund a new construction project?
Yes, in principle. Once the line closes, lenders generally do not restrict how you spend it. The new build is not the collateral, and you carry the interest cost with no rent coming in during construction.
What is the maximum amount I can borrow against an investment property?
In the network, the investment ceiling is 70% CLTV, with a maximum line of $500,000. Experian reports that market lenders more commonly cite 80% for investment lines, but that is a broader market figure, not what the network offers. The line is whatever remains after your existing liens.
Will a DSCR loan fund the construction itself?
Generally no. A DSCR loan underwrites a finished, income-producing property. It works as the takeout once the build is leased, and it can also be an equity-access option on an existing rental.
Can my LLC hold title on the property securing the line?
No. Title must sit with you individually or in an inter vivos revocable living trust. If the rental is already in an LLC, a vesting change or a DSCR cash-out refinance is the alternative, subject to program terms.
What happens when the draw period ends?
The line moves into a 25-year fully amortizing repayment on investment lines, and the payment steps up. Pricing floats the whole way and never converts to fixed. Plan the DSCR takeout so the property is leased and stable before repayment begins.
