The Quick Read: A HELOC on a rental is underwritten to you personally, so the file turns on equity left under the combined loan-to-value cap, a credit profile at the network floor, title held by an individual, and liquid reserves the lender is willing to count after closing.
- On Lendmire’s wholesale network, an investment-property line caps at 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000.
- Credit above 700 buys eligibility, not extra leverage. A 700 and a 720 reach the same 70% CLTV on an investment property.
- Reserves are set by the lender on each file, not by a regulator. Market surveys describe six months of payments or more as common on rentals.
- LLC-titled rentals cannot hold one of these lines. A DSCR cash-out refinance is the usual path for entity-held property.
Lendmire is a broker. It arranges these lines through select wholesale partners and never lends directly, so every figure here is subject to lender guidelines and a full file review.
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 a HELOC on a Rental Actually Is
An investment-property HELOC is a revolving line of credit secured by a rental you already own. It can sit in first or second lien position, and the lender underwrites it to the borrower rather than to the rent.
NerdWallet notes that the lender pool is smaller than for a primary-home line, that multiple appraisals may be required, and that lenders treat default risk as higher on rentals. Experian adds that the line typically is a second mortgage, and that a default can lead to foreclosure on the rental.
On the network Lendmire works with, the structure is narrow. An investment line runs a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed.
That last point matters for planning. The payment moves, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
Key Terms Defined
CLTV (combined loan-to-value): The first-mortgage balance plus the proposed line limit, divided by the property’s value.
Cash reserves: Liquid assets you still hold after closing, kept as a buffer against vacancy or a payment increase.
Lien position: Whether the line sits first or behind another mortgage in line for repayment.
Draw period: The stretch of the loan when you can borrow against the line and pay interest only.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly obligation of principal, interest, taxes, insurance, and any HOA dues. It is a property-level test, and it is not how a HELOC is underwritten.
How Underwriting Treats It, Step by Step
The deal works through the same checks in the same order, and a failure at any step ends it. Here is how each one works on the network.
1. Equity under the cap. The maximum line is the property value times the CLTV cap, minus what is already owed. On an investment property the cap is 70% CLTV. Take a rental with a first mortgage at 50% of value. The room is up to 20% of value, further limited by the $500,000 maximum line.
2. Minimum line size. The smallest line is $25,000 (Michigan is $10,000). A rental with a first mortgage near 65% of value leaves only about 5% of value under the 70% cap. On a modest-value property, that can fall below the minimum line, and the result is no offer.
3. Valuation. Because an investment line tops out at $500,000, and full appraisals begin only above $500,000, the file is structurally in the automated-valuation lane. A traditional appraisal is commonly skipped, though a higher CLTV may call for a secondary valuation, and a borrower can request a full appraisal anyway.
4. Credit. The floor on an investment property is 700, with no tier beneath it. The network uses a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. There are no rescores.
5. Debt-to-income. The maximum is 50%. Because the lender reviews the file on the interest-only payment at the maximum draw, a line you intend to use lightly still has to pass at full size.
6. Title and vesting. The property must be held by you as an individual or by your revocable living trust. An LLC cannot hold title, and the vesting rules are covered in their own section below.
7. Reserves. The lender looks at what liquid money is left after the transaction. This is the least standardized step, so it gets its own section next.
Those steps are why a rental HELOC reads differently from a DSCR file. Rent does not carry the file here. Some lenders count a portion of rental income, and practice varies by lender, but the question the lender is answering is whether you can carry the debt.
How Cash Reserves Work on a Rental HELOC
Reserves are lender policy, not a regulatory number. No government rule sets a reserve requirement for a line on a rental, so the figure comes from each wholesale lender and shifts with the file. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
NerdWallet reports that lenders often require six months of reserves or more on an investment HELOC, while a primary-home line may not need them unless something else on the file, like a high DTI, calls for them. Treat that as a market-wide statement. On Lendmire’s network, the reserve requirement is set by the wholesale lender on each file, so confirm the figure on your own scenario instead of planning around a survey average.
The calculation itself is simple, and it has the same shape on every file:
1. Identify the monthly obligation the lender counts, which on a rental includes the first mortgage and the new line.
2. Multiply it by the number of reserve months the lender requires.
3. Subtract funds that are already committed, such as the down payment or closing costs on another purchase.
4. What remains in verified liquid accounts must meet or exceed the total.
If a lender asks for six months and the combined monthly obligation is the base, the file needs six times that obligation sitting in accounts after closing. Funds spent at closing generally do not count twice.
Which accounts count is the lender’s call. Cash in checking and savings is the cleanest. Brokerage and retirement balances are treated differently from lender to lender, and some apply a discount to them. Ask before you assume.
Lenders also ask for recent account statements to show the money is yours and has been in place. A deposit that arrived last week, with no paper trail behind it, raises questions that a long-held balance does not.
With several financed properties, reserve rules tend to tighten rather than relax. Some lenders require reserves per financed property, and others scale the requirement with the count. The network also limits you to three lines in total. Combined exposure caps at $750,000 to $2,000,000 depending on the wholesale program, and a borrower with more than 15 financed properties is not eligible.
A lender’s required buffer is a floor. Your own vacancy and repair history may justify holding more.
Primary-Home Line vs. Investment-Property Line
| Factor | Primary residence | Investment property |
|---|---|---|
| Max CLTV on the network | Up to 90% (720+ credit only) | 70% |
| Minimum credit | 600 program floor | 700 |
| Max line | $750,000 | $500,000 |
| Draw structure | 3/17 or 5/25 | 5-year draw, 25-year repayment |
| Reserves | Lender-specific | Lender-specific, commonly required |
NerdWallet puts the typical maximum at 80% on an investment property, with many lenders below 70%. The network figure on an investment property is 70% CLTV, and there is no tier above it. The primary residence column describes owner-occupied lines. Second homes share its 90% ceiling, and only at a 720 or better credit profile.
A line above $500,000 is primary-residence only. It requires a 700 credit profile or better (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal. None of that touches a rental.
Where the General Rule Breaks
LLC-titled rentals. Fee simple or leasehold must be held by you individually or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a different product. The usual substitute is a DSCR cash-out refinance, which is arranged for entity borrowers subject to lender program eligibility and underwrites on rent coverage instead of personal income.
Rental recently listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Property types. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Texas. The 12-day waiting period, the one-lien-at-a-time rule, and 12-month seasoning bind primary residences only. A Texas rental is a non-homestead transaction and follows the standard investment table. Texas properties are limited to 10 acres.
Paid-off rental. With no first lien to subtract, the full CLTV allowance is available, up to the $500,000 line cap.
Availability. These lines are written only in 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 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On an investment file, a foreclosure is seasoned 7 years, and a deed-in-lieu, pre-foreclosure, or short sale 4 years.
The Equity-and-Coverage Test
Strong files clear two separate tests. The first is personal: credit, DTI, reserves, and equity under the cap. The second belongs to the property, because it decides which product fits.
A rental HELOC keeps the existing first mortgage in place. A DSCR cash-out refinance replaces it. If the first lien has terms worth keeping, the line is the natural fit. If the property sits in an entity, or personal DTI is already stretched, the DSCR route often fits better. A DSCR refinance typically tops out around 75% LTV on standard rentals, with about 6 months of seasoning common, and 1.00 coverage is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
Clearing 1.00 on a DSCR file is not the same as positive cash flow. The ratio compares rent to the full monthly obligation only, so repairs, vacancy, management, utilities, and capex sit outside it. The same caution applies to HELOC proceeds: money drawn against a rental still has to be repaid out of the portfolio’s real cash flow.

Misconceptions That Cost Applications
“Any bank will do it.” Few lenders offer a line on a rental, and the pool is smaller than for primary homes, as NerdWallet notes above.
“Rent qualifies me like a DSCR loan.” The line is mainly underwritten to the borrower. Any rent credit is partial and varies by lender.
“Reserves are optional.” They are often required on rentals, unlike many owner-occupied lines.
“Higher credit gets more leverage.” On this network it does not on an investment property. A 700 and a 720 reach the same 70% CLTV, so credit decides eligibility and nothing more.
“A rental HELOC fits any title.” LLC ownership is blocked. See above.
“I can open the line and leave it unused.” At least 75% of the line is drawn at closing, so the line is not a standby facility. It starts carrying interest on most of its limit on day one.
What to Do If You Are Short on Reserves
Shortfalls usually have one of three fixes. The first is to ask for a smaller line, which shrinks the payment base the lender multiplies by its reserve months and the draw it is reviewed around. The second is to move more assets into accounts the lender will count, and let them sit long enough to show on statements. The third is to switch products.
A DSCR cash-out refinance carries its own reserve rule, commonly around six months of PITIA, though that varies by lender, leverage, loan size, and transaction type. A refinance rarely makes sense if your only goal is to avoid reserves, but it can solve an LLC-title problem and a thin-DTI problem in the same move.
A short pre-application checklist saves rework:
- Current first-mortgage statement and an estimate of property value.
- Credit report within the lender’s 90-day window.
- Recent statements for every account you want counted as reserves.
- Lease or rental history on the property.
- Vesting documents showing individual or revocable-trust title.
- Insurance and title information for the rental.
Frequently Asked Questions
Can I get a HELOC on a rental property?
Yes, but through a smaller pool of lenders than for a primary home. On Lendmire’s network, an investment line reaches 70% CLTV with a 700 minimum credit score, up to a $500,000 line. The property must be held by you or your revocable living trust, not by an LLC, and availability is limited to 16 states.
How many months of reserves does a rental HELOC need?
The requirement is set by each lender and varies with the file. Market surveys report six months of payments or more as common on rentals, while primary-home lines may not need any. Confirm the figure for your own scenario before relying on a general range.
Does my rental income count toward qualifying?
Some lenders count a portion of it, but the line is underwritten mainly to your credit, DTI, equity, and reserves. It is not a DSCR-style test of whether rent covers the debt. A DSCR cash-out refinance is the product that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Will I need an appraisal?
Usually not. Because investment lines cap at $500,000, they sit in the automated-valuation lane, though a higher CLTV may require a secondary valuation. You can also request a full appraisal in any case.
What if my rental is in an LLC?
These lines cannot be written on LLC-titled property. You can change the vesting to your name or a revocable living trust, or use a DSCR cash-out refinance, which can be arranged for entity borrowers subject to lender program eligibility.
