The Quick Read: An investment property HELOC is a revolving credit line secured by the equity in a rental you own personally, and investors use it for down payments, rehabs, and reserves before refinancing into long-term debt, with investment lines on Lendmire’s network capped at 70% CLTV and $500,000 for borrowers with a credit score of 700 or better. The product is narrower than most investors expect. Title, credit, property type, and portfolio size all limit who can use it. Lendmire arranges these lines through select wholesale partners in 16 full-service states, subject to lender guidelines and full file review. This is not a commitment to lend.
- Leverage: an investment line tops out at 70% combined loan-to-value, and a higher credit score does not raise that ceiling.
- Credit: 700 is a hard floor on investment property, and there is no tier beneath it.
- Structure: a 5-year interest-only draw, then a 25-year amortizing repayment, with a floating payment throughout.
- Title: the borrower must hold title personally or in a revocable living trust. An LLC cannot hold title.
- Role in a portfolio: it is acquisition and rehab capital. A long-term DSCR loan is usually the takeout.
What Is an Investment Property HELOC?
An investment property HELOC is a standalone line of credit that sits in first or second lien position on a non-owner-occupied property. Lenders measure it against the equity in the home, which is the value minus what you owe. The line size is the property value times the lender’s maximum combined LTV, minus the existing mortgage balance.
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.
The word HELOC can cause confusion here. Strictly, it means home equity line of credit, and a rental is not a home. Some lenders may decline a HELOC on a rental but write a line secured by investment property under another name. Ask for the product by what it does.
Two collateral structures exist in the broader market. One puts the lien on the rental itself. The other puts it on the investor’s primary home and uses the money for rentals. The lines Lendmire brokers for investment property use the first structure. The borrower pledges the rental, and a default puts that rental at risk.
Experian describes this financing as less common than primary-residence lines. Availability depends heavily on which lender you reach.
How Underwriting Treats It, Step by Step
Underwriting an investment line follows a fixed sequence. Each step can end the file, so the order matters.
Step 1: Eligibility of the borrower and title. Title to the property must be held by an individual or 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 the investor needs a different product.
Step 2: Eligibility of the property. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. A property with five or more units is also outside the product.
Step 3: Credit. Investment property requires at least a 700 score. Credit above 700 buys no extra leverage on an investment line, because 720 and 700 both reach the same 70% ceiling. The score is a single-bureau figure tied to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
Step 4: Equity and combined leverage. Take the value, apply the 70% CLTV ceiling, and subtract the first mortgage. What remains is the maximum line, up to $500,000. The minimum line is $25,000, or $10,000 in Michigan. A free-and-clear rental has up to 70 points of value available, bounded by the dollar cap, and a first mortgage at 50% of value leaves about 20.
Step 5: Valuation. Because an investment line caps at $500,000 and full appraisals begin only above that size, the file runs in the automated-valuation lane. It commonly closes with no traditional appraisal. A higher CLTV may call for a second valuation, and a borrower can request a full appraisal in any case.
Step 6: Debt-to-income. The ceiling is 50%. The lender qualifies you on the interest-only payment calculated on the maximum draw. That means the line is tested as if fully drawn, whether or not you plan to draw all of it. Every financed property on your personal credit counts toward that ratio, so the ratio can become the binding limit before the equity does. How rental income counts toward the ratio varies by lender, so expect to document leases and rent.
Step 7: Portfolio limits. A borrower is limited to three lines in total. A borrower with more than 15 financed properties is not eligible.
The Draw and Repayment Lifecycle
A HELOC has two phases. The CFPB’s plain-language explanation describes a draw period, during which you can borrow up to the limit, followed by a repayment period in which borrowing stops and the balance is paid down. It also notes that HELOC pricing is usually variable, so payments can change from month to month.
Investment lines run one structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats across both phases and never converts to fixed. The CFPB’s HELOC brochure adds that on a variable plan the payment can change even when you draw no more money.
Two details separate this product from the revolving line most investors picture:
- Most of the line is funded at closing. At least 75% of the line is drawn at closing. This works like a funded second lien with a small amount of dry powder, not a large standby reserve.
- Later draws have a floor. After closing, a subsequent draw is typically at least $1,000, and higher in Texas.
The step-up at the end of the draw phase deserves a plan. When the interest-only years end, principal repayment begins. A balance that felt manageable on interest-only payments can strain a rental’s income once it amortizes. The draw period is temporary, so build the repayment payment into the plan from the start.
Structures and Variations That Exist
Four structures show up in practice, and they behave differently.
A line on the rental, in second position. The first mortgage stays untouched, and the line sits behind it. This is the common case. It keeps the original first-lien terms but adds a second payment.
A line on the rental, in first position. This applies to a property with no existing mortgage. The line is the only lien.
A fixed second mortgage instead of a line. Some lenders offer a fixed-amount second mortgage rather than a revolving line. Investors who know the exact amount they need sometimes prefer it. It is a different product with different mechanics.
A line on the primary home. Many investors pull equity from the home they live in and deploy it into rentals. That is a different product with different leverage rules, and it puts the home at risk. A DSCR refinance on the rental itself is the other way to reach rental equity.
The table below compares the two most common ways to pull equity from a rental you own personally.
| Factor | Investment line (HELOC) | DSCR cash-out refinance |
|---|---|---|
| Lien | First or second | New first mortgage |
| Leverage cap | 70% CLTV | About 75% LTV, standard rental |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
| Payment | Floats; 5-year interest-only draw | Fixed 30-year spine; options vary |
| Reviewed on | Personal credit and DTI | Rent versus PITIA, plus credit |
| Title | Individual or revocable trust | Individual or entity |
On a cash-out refinance of a standard rental, most programs in the network top out around 75% LTV, with about six months of seasoning expected. Short-term-rental collateral tops out at 70% on a cash-out. DSCR loans to LLC-titled borrowers are available subject to lender program eligibility, which is the sharpest structural difference from the line.
Where the General Rule Breaks
The general rule says a rental with equity can support a line. Several named edge cases break it.
The LLC problem. Many investors hold rentals in entities for liability reasons. The line cannot follow them there. An investor who has already moved properties into an LLC faces a vesting change that may carry its own costs and consequences, or a move to the DSCR route.
The credit gap. Many DSCR programs in the network start around a 620 floor, with most wanting about 660. An investment line starts at 700. An investor at 680 may qualify for a DSCR cash-out and not for a line.
The multifamily gap. Properties with 2-4 units are eligible here. Five or more units are not. Investors holding small apartment buildings need a commercial or portfolio product instead.
The portfolio cap. Past 15 financed properties, the product is closed. An investor scaling fast can reach that number sooner than expected.
The blanket-line myth. A single line against several properties usually requires a commercial or portfolio product. A standard investment line is secured by one property, so cross-collateral deals fall outside it.
Geography. Lendmire arranges these lines in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. The DSCR footprint is wider, at 41 markets including Washington, D.C. Some states add their own conditions. Texas, for example, limits properties to 10 acres.
How the Line Fits a Portfolio, Stage by Stage
An investment line is useful at some points in a portfolio and a liability at others. The sequence below shows how the roles change as the portfolio grows.
| Stage | Typical use | Main risk | Exit |
|---|---|---|---|
| Property 1 | Down payment on property 2 | Floating payment on drawn funds | Refinance or paydown |
| Property 2-3 | Rehab capital | DTI climbing | DSCR cash-out |
| Property 4-8 | Reserves, next deposit | Stacked second liens | Refinance, then repay |
| Property 9+ | Selective only | Portfolio cap, DTI | DSCR as the main tool |
The takeout matters more than the draw. The line has to be repaid by refinancing, selling, or paying it down from cash flow. A property bought with line proceeds and then rehabbed gives a clean exit, because a DSCR refinance can pay the line off once the rent is stabilized. A turnkey rental bought at market gives no such exit, since there is no forced equity gain to refinance into.
A DSCR refinance on a property that already carries a second lien has to pay that lien off or work around it. How a lender treats a second lien depends on its own guidelines. Check this before drawing, not after.
Stress-Testing the Plan
Three pressures hit a line-funded plan, and each can be sized in percentages.
Value drops. The 70% ceiling is measured against value. A rental carrying 60% combined leverage has 10 points of room. A decline of roughly 15% in value pushes that same debt past 70%, which matters if you later refinance or if the lender revalues the property.
Payments rise. Pricing floats across both phases. Any plan that only works at today’s payment is fragile. Run the rental’s coverage with a meaningfully higher payment on the line and see whether it still holds.
Vacancy. DSCR compares monthly rent to PITIA only. A property that clears 1.00 is not necessarily producing positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation. A line payment on top makes that gap wider.
Coverage thresholds also affect the takeout. Many select DSCR programs start at 1.00, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Neither path helps if the property cannot support its own debt.
Is It the Right Tool for You?
For an individual owner with 700-plus credit, a rental held in personal name, and a defined project, a line can supply capital without disturbing the first mortgage. For an investor whose rentals sit in LLCs, whose credit sits near 680, or who already carries many financed properties, the DSCR cash-out is usually the better tool. It is built on the property’s own income and tolerates entity titles.
A few questions settle most cases:
1. Who holds title today? If an LLC does, the line is likely off the table.
2. What is the takeout? If you cannot name one, do not draw.
3. How many financed properties do you have? Near 15, the line is closed to you.
4. How long do you need the money? A short bridge fits a line. Long-term capital fits a fixed first mortgage better.
5. What is your DTI after the line is counted as fully drawn? If it breaks 50%, the file fails before it starts.
Lendmire’s complete DSCR loans guide explains the long-term side of this sequence.
Key Terms Defined
CLTV: combined loan-to-value, which adds every lien on the property together and divides by its value.
Draw period: the stretch when you can borrow against the line, which is five years on an investment line.
Repayment period: the stretch after the draw period when you repay principal and interest, which is 25 years on an investment line.
Automated valuation: a computer-based estimate of value used in place of a full appraisal on smaller lines.
DSCR: debt service coverage ratio, which is monthly rent divided by monthly principal, interest, taxes, insurance, and any HOA dues.
Takeout: the refinance or sale that repays a short-term line.
Vesting: how title to a property is held, whether by an individual, a trust, or an entity.
Frequently Asked Questions
Can I get an investment property HELOC on a rental held in an LLC?
No. Title must be held by the individual borrower or a revocable living trust, so LLCs, corporations, partnerships, and irrevocable, blind, or land trusts are all excluded. A property already deeded to an entity needs a vesting change, or the investor can look at a DSCR cash-out instead. That second route is available subject to lender program eligibility.
How much can I borrow against a rental?
Up to 70% combined LTV, with a line between $25,000 and $500,000 (the minimum is $10,000 in Michigan). Credit must be 700 or better, and 720 buys no extra leverage on investment property. The line equals value times 70%, minus the existing mortgage balance. Every figure is subject to lender guidelines and full file review.
Will the lender order a full appraisal?
Usually not. Investment lines cap at $500,000, and full appraisals are required only above that size. A higher CLTV may call for a second valuation, and a borrower can ask for a full appraisal.
What happens when the draw period ends?
Repayment begins. The five-year interest-only draw gives way to a 25-year amortizing schedule, and the monthly payment steps up as principal is added. The pricing floats the whole way and never converts to fixed. As the CFPB brochure notes, the payment can also change during the draw period even if you borrow no more.
Does a line on one rental affect my next DSCR loan?
Yes, it can. A second lien adds debt to the property, and a later refinance has to pay the line off or work around it. Personal debt-to-income also rises as financed properties accumulate. How a lender treats a second lien depends on its own guidelines, so check before drawing.
