The Quick Read: Opening one means passing two reviews, one on you and one on the building, and placing the new line in second position so the existing first mortgage stays exactly as written. Only the first mortgage’s balance, not its low payment terms, shrinks the room left for the line. Everything below is subject to lender guidelines and full file review.
- The first mortgage is untouched. Its balance counts against your combined leverage, and its payment counts in your debt-to-income ratio.
- On an investment-property condo, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line.
- On a primary residence or second home, ceilings run higher, but the top tier requires a 720 score.
- The condo building is underwritten separately from you. Litigation, weak insurance, or heavy investor ownership can sink a strong borrower.
- The line must be titled to an individual or a revocable trust. A condo held in an LLC needs a vesting change or a different product.
What Is This Product, Exactly?
A home equity line of credit is a revolving loan secured by the unit. You draw funds during an interest-only period, then repay the balance over a longer amortizing period. Pricing floats and never converts to fixed.
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.
Behind a low first mortgage, the line is a second lien. The first loan keeps its rate, term, and payment. Only the new money carries new pricing.
That is the appeal for an investor sitting on cheap first-lien debt. You pull equity without refinancing away a loan you could not replace today.
The trade-off is that a second-position line on a rental is a narrow product. Many large retail lenders avoid it, and RentalRealEstate notes that a line secured directly by a rental is offered by fewer lenders and carries stricter requirements. Across Lendmire’s wholesale network, the lenders that write these lines do exist, but they apply tighter rules on occupancy, credit, and vesting than a typical owner-occupant line.
How Does Underwriting Treat a Condo? Step by Step
Underwriting runs in a fixed order, and a failure at any step ends the file. Pre-checking the early steps before paying for anything saves money.
1. Pick the occupancy. Primary residence, second home, and investment property carry different ceilings, credit floors, and caps. The occupancy you declare drives every number that follows.
2. Value the unit. On lines at or below $500,000, the network ordinarily uses an automated valuation with no traditional appraisal, though a higher CLTV can trigger a secondary valuation. Above $500,000, a full appraisal is required, and a borrower may request one at any size.
3. Run the combined-leverage math. Take the unit’s value, multiply by the maximum CLTV for your occupancy and credit tier, then subtract the first mortgage balance. What remains is the most the line can be, before size caps.
4. Underwrite the borrower. The network allows a maximum 50% debt-to-income ratio, or 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. The test counts the first mortgage payment, the association dues, and the new line, calculated on the interest-only payment at the maximum draw.
5. Review the building. Expect an association questionnaire, proof of the master insurance policy, and a check on pending litigation, owner-occupancy mix, and investor concentration. Most lenders pause approvals while the association is in a lawsuit.
6. Confirm title. The unit must be held by the individual borrower or a revocable living trust.
7. Close and fund. At least 75% of the line is drawn at closing. Later draws carry a minimum, commonly $1,000 on one of the network’s two programs.
How Does a Low First Mortgage Change the Sizing?
A low first balance opens room, but a low first rate does not. Lenders count what you owe, not what it costs you.
Consider a condo with a first mortgage equal to 40% of its value. On an investment-property line with a 70% CLTV ceiling, the line could use up to the remaining 30% of value, then hit the $500,000 cap if the unit is valuable enough. Now take the same unit with a first mortgage at 60% of value. Only 10% of value is left, and the line may fall below the lender’s minimum size of $25,000.
Many investors miss one point here. Lenders generally test CLTV against the full credit limit, not the amount you actually draw. Drawing less on day one does not make the test easier.
Credit score matters in a specific way. On investment lines, the 700 minimum keeps you eligible, but scores of 700 and 720-plus both land at the same 70% CLTV. A higher score does not buy more leverage on a rental.
Primary, Second Home, or Rental Condo?
The same building and the same equity produce different answers depending on occupancy. All figures are typical network guidelines, not promises.
| Occupancy | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Investment property | 70% | 700 | $500,000 |
| Second home | Up to 90% at 720+ | 640 | $500,000 |
| Primary residence | Up to 90% at 720+ (to $500,000) | 600 | $750,000 |
On a primary residence, the lower credit tiers step down fast. A 640 score tops out near 80% CLTV, and a 620 score near 70% with a $400,000 line cap. A primary-residence line above $500,000 requires at least a 700 credit profile (720 on the longer-runway structure, introduced below) and caps at 75% CLTV with a full appraisal.
Two wholesale programs sit behind these numbers, and they differ in places. The higher-leverage program allows combined exposure up to $2,000,000 for a borrower. The longer-runway program offers the 25-year repayment structure, caps combined exposure at $750,000, and has stricter tradeline and housing-history standards. Each figure applies only within its own program’s terms.
The federal HELOC booklet adds a rental caution worth reading. The CFPB’s HELOC booklet warns that a line’s terms may prohibit renting the home to others. Consumer forms are written with owner-occupants in mind, so an investor should read the occupancy and use language before signing. Whether a rental qualifies is set by lender and investor guidelines, not by the regulator.
What Does the Building Review Actually Check?
The building is a second underwriting file, and it fails more often than borrowers expect. A strong credit profile cannot offset a weak association.
| Building factor | What the lender wants | Common problem |
|---|---|---|
| Association finances | Funded reserves, low delinquency | Large unpaid dues |
| Master insurance | Adequate hazard and liability | Gaps or lapses |
| Owner-occupancy mix | Reasonable owner share | Investor concentration |
| Litigation | None pending | Active suit pauses approval |
The network accepts condominiums, including non-warrantable ones. Warrantable is a label for projects meeting standard tests on owner-occupancy, association finances, and insurance. Non-warrantable acceptance gives a troubled building a path, though pricing and leverage can adjust.
Co-ops and condotels are not eligible on either program. If the building rents nightly through a hotel-style program, this product is not the route.
Step-by-Step: How to Open the Line
Work in this order so you spend money only after the cheap checks pass.
1. Pull the association documents first. Request the questionnaire, the master insurance certificate, and the budget. Read them for litigation and special assessments before anything else.
2. Read your first mortgage documents. Look for an additional-lien covenant or due-on-sale language. Federal law limits due-on-sale enforcement in some situations, but that protection is usually described as aimed at owner-occupied homes. On a rental, the contract wording matters more.
3. Confirm title. If the unit sits in an LLC, corporation, partnership, or irrevocable, blind, or land trust, it cannot hold title for this line. Moving title can also trigger the first mortgage’s due-on-sale clause, so test that before retitling.
4. Check the first lender’s position. Get the servicer’s stance on a second lien in writing if the unit is a rental.
5. Choose the occupancy and credit tier. Check your credit report age too. The report must be no more than 90 days old at closing, and there are no rescores.
6. Apply and order valuation. Upfront costs can include appraisal, title, and recording fees. Application fees may be non-refundable if you are declined, as the booklet notes.
7. Draw. Plan your first draw knowing that at least 75% of the line is advanced at closing. Treat that as the amount you will carry from day one.
The Federal Register notice confirms that lenders must hand over that booklet at application, so the cost and use disclosures should reach you early.
Where the General Rule Breaks
A few situations flip the usual answer.
The condo is in an LLC. The personal line is closed. A DSCR cash-out refinance replaces the first mortgage and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network, cash-out tops out around 75% LTV on a standard rental, with about six months of seasoning commonly expected. Giving up a low first mortgage is a real cost, which is why the choice depends on how cheap that first loan is. Lendmire’s complete DSCR loans guide walks through that comparison.
You plan to refinance the first later. A new first lender wants first position. The line must then be paid off or subordinated, and the line lender has no duty to subordinate. Ask before you open it.
Your first mortgage is large relative to value. If the first plus the new line would pass the CLTV ceiling, there is no room. The line also has to clear the minimum size.
You hold many financed properties. A borrower is limited to three lines on this network, and owning more than 15 financed properties makes you ineligible. The personal debt-to-income test can also bind before equity does. For an investor with a growing portfolio, property-rent-based lender review may fit better.
The building fails review. The fallback paths differ by failure type.
| Situation | Practical path |
|---|---|
| Litigation pending | Wait for resolution, or use a primary-home line |
| Heavy investor concentration | Ask about non-warrantable acceptance |
| Unit titled to an LLC | Retitle or use a DSCR cash-out |
| Not enough room after the first | Smaller line, or cash-out refinance |
Using a HELOC on the primary home instead. Many investors draw on a primary-home line to fund rental purchases, because it is more widely available than a rental-secured line. The trade-off is that your own residence secures the debt.
Preserve the Low Rate or Get More Cash?
The decision depends on which constraint is binding for you.
If your first mortgage is cheap and has a low balance, a second-lien line is usually the cleaner tool. You keep the locked payment, and only the new draw floats. If your first balance is large relative to value, or the unit is in an LLC, a cash-out refinance may be the only way to get meaningful proceeds.
Remember that a floating line behind a fixed first is a stress-testing exercise. The first payment stays flat, but the second can move. Test your coverage on the line at a higher draw than you plan to use.
One practitioner pattern shows up often across the network. Files fail on vesting and building health far more often than on credit. Pulling association documents and checking the deed before applying is the most affordable screen available.
Drawn funds can also serve as the down payment on a separate DSCR purchase. For that, keep in mind that 1.00 coverage is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, and management sit outside the ratio.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Key Terms Defined
Second lien: a loan that sits behind an existing mortgage and is paid second if the property is sold or foreclosed.
Combined loan-to-value (CLTV): all loans secured by the unit, divided by its value.
Draw period: the interest-only stretch when you can borrow from the line.
Warrantable condo: a project that meets standard tests on owner-occupancy, association finances, and insurance.
Vesting: the legal name in which the property’s title is held.
Frequently Asked Questions
Can I get a HELOC on a condo I rent out?
Yes, on an investment-property line, though it is the narrowest part of the market. The network ceiling is 70% CLTV, with a 700 minimum score and a $500,000 maximum line, and title must be held individually or in a revocable trust. Qualification is subject to lender guidelines and full file review.
Does a low first mortgage rate increase my line?
No. Only the first mortgage balance enters the combined-leverage math. The rate affects your payment and your debt-to-income ratio, but not how much equity is available.
Will the line change my first mortgage?
No. The line is a separate lien, though the first servicer’s documents may carry a covenant about additional liens, so read them before applying.
What if my building is in litigation?
Most lenders pause approvals until the suit resolves. Waiting, or using a line on a different property you own, are the usual paths. A non-warrantable condo can still be eligible once the other building factors check out.
Can an LLC-owned condo get one?
Not directly. LLCs cannot hold title on this line, so the unit needs a vesting change or a DSCR cash-out refinance instead. Moving title can trigger the first mortgage’s due-on-sale clause, so check that first.
