Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The Quick Read: An investment property HELOC is a revolving credit line secured by a rental. Lenders usually want cash left in the bank after closing, called reserves, on top of equity and credit. Across Lendmire’s wholesale network, an investment line tops out at 70% combined loan-to-value (CLTV) and $500,000, and the reserve count is set by the lender and the file.
- Reserves are your own liquid cash after closing. They prove you can keep paying the line if the rent stops.
- Market surveys set a higher bar than a primary home. Bankrate reports at least six months on investment lines. On the network, an investment line also requires a 700 minimum credit score and allows a 50% maximum debt-to-income ratio.
- Title matters. The property must be held by you personally or by your revocable living trust. An LLC cannot hold title on these lines.
- Availability is narrow. Investment lines run in Lendmire’s 16 full-service states, not the full 41-market DSCR footprint.
- LLC-held rentals and higher leverage usually point to a DSCR cash-out refinance instead.
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.
What Does a Cash Reserve Actually Mean on a Rental Line?
A cash reserve is liquid money you still have after closing. It is not the money you used for closing costs or a down payment. The lender wants proof that you could carry the payment for several months if a tenant leaves or stops paying.
That is the whole logic. A rental can go vacant. A credit line secured by a rental sits on top of that risk. So the lender asks for a cushion outside the property.
Bankrate says lenders weigh both the borrower’s finances and the property’s finances, and that investment-property criteria tend to be stricter than for a primary home. Its comparison puts cash reserves at the center of the difference: at least six months of payments on an investment line, while a primary-residence line may need none. That figure is a market-wide survey number. It is not a statement of what any single lender in Lendmire’s network requires.
Here is how the two views line up on the points the network sets.
| Item | Market survey | Lendmire network, investment line |
|---|---|---|
| Reserves | At least 6 months of payments | Set by lender and file |
| Minimum credit | Set by the lender | 700, hard floor |
| Maximum line | Set by the lender | $500,000 |
The network’s guideline set does not hand you one universal reserve number for an investment line, so be wary of anyone who offers one. Reserves depend on the lender, the leverage, the line size, and the file. What is fixed is the rest of the box: 70% CLTV, 700 credit, 50% DTI, and a $500,000 ceiling.
How Underwriting Handles an Investment Line, Step by Step
Underwriting an investment line runs through six checks. Some of them are hard gates, and some are judgment calls. Reserves sit in the middle.
Step 1: Eligibility of the property and title. The property must be a single-family home, a 2-4 unit building, a townhome, a PUD, or a condo (including non-warrantable condos). Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. Title must sit with you or your revocable living trust.
Step 2: Equity and combined leverage. CLTV adds every lien on the property, including the new line, and divides by value. On an investment property, the network ceiling is 70% CLTV. Credit above 700 does not buy more leverage here, because 720 and 700 reach the same tier.
Picture a rental whose first mortgage equals 45% of its value. A 70% CLTV cap leaves room for a line equal to 25% of value. If that math lands above $500,000, the line size cap binds first. A property owned free and clear has the full 70% to work with, subject to the same ceiling.
Step 3: Credit. The floor on an investment line is 700. Lenders use a single-bureau score tied to the primary wage earner, and the report can be no more than 90 days old at closing.
Step 4: Debt-to-income. The maximum is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to draw. A small planned draw does not shrink the number the file is tested against.
Step 5: Reserves. Here the lender checks your statements for liquid assets left after closing. Then it compares them to the required months of payments. Which accounts count, and how the months are measured, is a lender-specific call.
Step 6: Valuation. Because investment lines cap at $500,000, they commonly use an automated valuation with no traditional appraisal. A borrower can request a full appraisal, and a higher CLTV may call for a second valuation.
That sequence matters. Equity gets you in the door. Credit and DTI keep you there. Reserves are the cushion at the end.
How Much Reserve Cash Do You Need? A Sizing Method
Sizing your reserve takes a few moves, which are listed below. The method matters more than any one lender’s month count, because the month count changes from file to file.
1. Find the qualifying payment. On this product it is the interest-only payment at the maximum draw. Ask the lender for that payment.
2. Multiply by the required months. If a lender wants six months, your target is six times that payment.
3. Add other properties if the lender stacks reserves. Some lenders count reserves across every financed property. Ask which way yours works.
4. Keep the reserve separate from the line. At least 75% of an investment line is drawn at closing. That means you start paying on most of the line immediately, and the undrawn balance is not a substitute for cash in your own account.
Run it as a modeled example. Say the lender requires six months, and the qualifying payment is P. Your target is 6P in eligible accounts after you pay all closing costs. If you hold 6P exactly and then spend some on a repair, you have slipped below the requirement before the line even funds. Hold a buffer.
Notice what the line itself does to your reserve math. The draw period is five years. After that, the line moves into a 25-year fully amortizing repayment, and the payment steps up. The payment floats across both periods and never converts to a fixed payment.
Which accounts count?
Do not guess here. Ask each lender these questions before you pay for anything:
- Do checking and savings count at full value?
- Are brokerage balances counted at full value or reduced?
- Do retirement accounts count, and at what percentage?
- Can proceeds from another line or loan count?
- Must funds be seasoned in the account for a set period?
- Are reserves measured per property or across all financed properties?
Answers differ by lender, so get them in writing for your own file.
The Structures Behind the Line
An investment line is a standalone line that can sit in first or second lien position. If you already have a mortgage, the Consumer Financial Protection Bureau describes a HELOC as an open-end line you can borrow against repeatedly during a draw period. After that comes a repayment period. It is a second mortgage you pay in addition to the first.
The same agency’s older HELOC booklet shows how a limit is built. The lender takes a percentage of appraised value and subtracts what you owe. The network’s version of that percentage on an investment property is 70%.
Three variations are worth knowing.
A line on the rental itself. This is the true investment property HELOC. It carries the 700 floor, the 70% CLTV cap, and the reserve test this article is about.
A line on your primary home, used for investing. The ceiling is higher on a primary residence. It reaches 90% CLTV only at a 720-or-better credit profile. Many investors tap their home for this reason, and a primary-home line may carry little or no reserve test. The catch is risk: your house, not the rental, secures the debt. The CFPB booklet also warns that renting out the home itself may be prohibited by a line’s terms. That is about renting the home, not about spending the funds elsewhere.
A line on a property you own free and clear. With no first mortgage, the line takes the first lien position. Sizing is simple, and the 70% cap does the work.
On lines above $500,000: they exist only on primary residences, with a full appraisal. An investment line never gets there.
Where the General Rule Breaks
Reserve rules live inside lender policy. These other limits are written into the guidelines.
Entity title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your rental is already deeded to an LLC, you need a vesting change or a different product. This is the sharpest structural difference from a DSCR loan.
Property and line counts. A borrower is limited to three lines. Combined exposure caps vary by program, from $750,000 to $2,000,000. Anyone who owns more than 15 financed properties is not eligible.
Listed properties. A property that is listed for sale, or was listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Thin lender market. Many banks do not offer lines on non-owner-occupied rentals at all. A BiggerPockets thread describes smaller community banks and credit unions as the usual source. Availability also shifts. A lender that offers the product today can pull back.
Property decline. The CFPB’s HELOC booklet says a lender can reduce your credit line if the home’s value falls substantially. It also says that if you sell, you generally must pay off the line in full. For an investor planning an exit, that last point matters.
Derogatory credit. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow seven years for a foreclosure and four for a deed-in-lieu, pre-foreclosure, or short sale.
Cash flow also matters after closing. The payment floats, and a vacancy can squeeze you. Lendmire’s piece How to Use an Investment Property HELOC When Rental Cash Flow Dips covers that scenario.
HELOC or DSCR Cash-Out? Pick by What You Actually Need
Choose by structure, not by habit. A HELOC is a revolving line with a floating payment. A DSCR loan is a term loan. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Structure | Revolving line, floating payment | Term loan, 30-year fixed spine |
| Leverage | 70% CLTV ceiling | Around 75% LTV on standard rentals |
| Credit | 700 minimum | 620 floor in parts of network |
| Title | Individual or revocable trust | LLC allowed, subject to program terms |
| Reserves | Set by lender and file | Commonly around 6 months of PITIA |
PITIA stands for principal, interest, taxes, insurance, and association dues. DSCR reserves vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, while larger loans can carry higher requirements. Those are ranges, not promises.
A HELOC fits an investor who needs flexible access to cash, owns the property personally, and can hold the reserve. A DSCR cash-out fits an LLC-held property, a larger draw, or a borrower who wants a fixed-term structure. Many investors compare both. For the full picture, see the complete DSCR loans guide.
One caution. Clearing a coverage ratio of 1.00 on a DSCR loan does not mean the property cash flows. DSCR compares rent to PITIA only. Repairs, vacancy, management, and utilities sit outside it.
Honestly, this one is a genuine toss-up for investors with clean personal title. The HELOC’s flexibility is real, but so is the floating payment and the reserve cash tied up behind it.
Key Terms Defined
Reserves: Liquid assets you still hold after closing, separate from closing costs and any down payment.
HELOC: A home equity line of credit, a revolving line you can draw on and repay repeatedly.
CLTV: Combined loan-to-value, which divides all liens against the property, including the new line, by its value.
Draw period: The stretch when you can borrow from the line. On investment lines it is five years, interest-only.
Repayment period: The stretch after the draw period when the balance amortizes. On investment lines it is 25 years.
DSCR: Debt service coverage ratio, which compares a rental’s monthly rent to its monthly debt payment.
DTI: Debt-to-income ratio, the share of your income that goes to debt payments.
Frequently Asked Questions
Can I count the HELOC itself as my reserves?
Generally no. Lenders treat reserves as your own liquid assets after closing. At least 75% of an investment line is drawn at closing, and borrowed money does not prove you can carry payments. The lender decides what counts, so ask before you rely on any balance.
Do reserves apply per property or across my whole portfolio?
It depends on the lender. Some measure reserves only on the subject property, and others stack them across every financed property. The network separately limits you to three lines and rules out borrowers with more than 15 financed properties.
Can my LLC borrow on an investment HELOC?
No. LLCs cannot hold title on these lines, and a property already deeded to one needs a vesting change first. A DSCR cash-out refinance can work for LLC-held rentals, subject to lender program eligibility.
Will a HELOC on my rental affect a later DSCR loan?
Yes, it can, because a second lien counts toward the property’s combined leverage, so a later refinance has to account for it. DSCR underwriting leans on property-level rental income rather than personal DTI. Your leverage and credit still matter.
Is an investment HELOC available in every state?
No. Investment lines run in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. DSCR loans run.
