The Quick Read: Which providers write a line behind your first mortgage depends on the condo, the title, the building, and your credit, so the practical move is to match your file to a wholesale program that accepts condos in second position while your existing first mortgage stays untouched. A line like this is underwritten on you and the equity, not on the rent. Lendmire is a mortgage broker, not a lender, so the useful question is which program fits your situation, not which company tops a list.
- A new line behind your first mortgage records as a second lien, and the first loan keeps its balance, payment, and terms.
- On an investment condo, the network ceiling is 70% combined loan-to-value (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 this product.
- The building gets reviewed as well as you. Non-warrantable condos are eligible on this network, but condotels are not.
- Providers for investment lines are a thin set, which is why sourcing is the real obstacle.
Why You Won’t Find a Neutral Ranked List
Investment-property HELOCs are a narrow product, and the set of lenders writing them shifts. NerdWallet says not every lender offers them, requirements are strict, and lenders see higher default risk than on a primary home. It adds that more than one appraisal may be required.
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.
Investor discussions on BiggerPockets describe availability that is spotty, with lenders starting and stopping these lines. A list of names goes stale fast. A way to judge a provider does not.
So this article skips the ranking and shows how these lenders think. The strongest program for your file depends on the occupancy, the equity, your credit profile, and the building. Four tests sort providers: lien position, title, condo review, and valuation.
Key Terms Defined
Second lien. A loan recorded behind your existing mortgage. The first lender gets paid first if the property is sold or foreclosed.
CLTV (combined loan-to-value). Your first mortgage balance plus the full new line limit, divided by the property value.
Warrantable condo. A condo building that meets standard project rules on things like owner-occupancy mix, reserves, and litigation. A non-warrantable condo misses one or more of those rules.
Draw period. The stretch when you can borrow from the line, paying interest only on this network’s investment product.
Vesting. How title to the property is held, such as in your own name, a trust, or an LLC.
What Is a HELOC on a Condo Behind a First Mortgage?
It is a standalone line of credit secured by the condo, recorded behind your existing first loan. The Consumer Financial Protection Bureau describes a HELOC as an open-end line you can borrow against repeatedly, with a draw period followed by a repayment period. Equity is the home’s value minus what you owe.
The federal consumer-finance regulator also explains that a HELOC on a mortgaged home is a second mortgage, paid in addition to the first. It notes HELOC pricing usually adjusts, so payments move with the balance. That matters on a thinly covered rental.
The agency’s consumer material is written for people borrowing on their own homes. Use it for definitions, not for investment-property rules.
The alternative is a first-lien line, which would pay off the old mortgage. That defeats the goal if your first loan is one you want to keep.
How Underwriting Treats This Line, Step by Step
Across the wholesale network, a condo second-lien line passes through the same sequence. Each step can end the file.
Step 1: Confirm lien position on purpose. A line behind your first mortgage is a second lien. Before designing anything, read the first note and deed of trust to confirm a junior lien is allowed.
Step 2: Run the CLTV math. The formula is condo value times the allowed CLTV, minus every existing lien. The full line limit counts, not just what you draw. A second lien already on title shrinks the room point for point.
Step 3: Qualify the borrower. This product is reviewed around personal credit and debt-to-income (DTI), not on rent. DTI tops out at 50%, and the payment is calculated on the interest-only amount at the maximum draw. Your first mortgage payment and the new line both count against you.
Step 4: Check credit. Investment lines need a 700 minimum. The score model is a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history on investment files follows a 7-year path, or 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
Step 5: Review title. Fee simple or leasehold held by you or your revocable living trust is eligible. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
Step 6: Review the building. The building is a second approval gate. Reviewers look at the budget, reserves, delinquent dues, master insurance, litigation, the share of commercial space, and the owner-occupied versus investor split. Passing review is not approval of the loan.
Step 7: Value the condo. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal, though a higher CLTV may call for a secondary valuation. You can request a full appraisal in any case. That option helps when a building has few comparable sales or after renovations.
Step 8: Draw and repay. Investment lines run a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats across both periods and never converts to fixed.
The CLTV Math, Shown in Percentages
On an investment condo, the network ceiling is 70% CLTV. Here is how much room remains behind a first mortgage, with the first loan expressed as a share of value.
| First mortgage as % of value | Investment CLTV ceiling | Room for the full line |
|---|---|---|
| 40% | 70% | 30% of value |
| 50% | 70% | 20% of value |
| 60% | 70% | 10% of value |
| 65% | 70% | 5% of value |
Remember that the whole line counts at closing, not only the drawn amount. A condo bought with a small down payment starts above the investment cap, so equity has to build before a line fits.
Primary-residence and second-home lines run on different tables. A second home can reach 90% CLTV only at a 720-or-better profile, and a primary residence reaches 90% only at 720 and up to $500,000. Those figures never describe an investment condo.
Who Writes These Lines, and How to Sort Them
You will meet a few categories of provider. Which one fits depends on your file.
- Credit unions and community banks. Programs vary by institution, and some write only on a primary residence, so ask each one about investment condos directly.
- Large retail lenders. Ask whether they accept investment condos at all or limit lines to a primary home.
- Wholesale network lenders reached through a broker. A broker shops several programs and matches the property, equity, and credit to the one that accepts it.
The wholesale route has one limit. This HELOC product is available only in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint, so confirm that your property sits inside it.
A broker can compare programs side by side. That is the practical case for the broker route: lender appetite for condos in second position differs, and a decline from one program does not tell you much about another. Sort any provider by the same questions:
- Does the program accept your occupancy type and this property type?
- Does it allow your title structure?
- What CLTV ceiling and maximum line apply to your credit tier?
- How does it value the condo?
- How is the line structured, in draw period and repayment?
Where the General Rule Breaks
These are the edge cases that decide files before the math does.
An existing second lien. It cuts CLTV room, and it can make a new junior lien harder to place.
HOA rental caps and minimum-lease terms. Building rules on how many units can be rented, or for how long, can sink a file before CLTV comes up.
Non-warrantable condos. They are eligible on this network. Condotels are not offered, and neither are co-ops.
A condo owned by an LLC. It needs a vesting change, or a DSCR cash-out refinance instead. A DSCR loan can close in an LLC name, subject to lender program eligibility.
Family living there rent-free. That does not earn owner-occupied or second-home treatment. Expect the investment tier.
Portfolio limits. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
A recently listed property. A condo listed for sale, or listed within the past 60 days, is ineligible in several states.
A rent-qualified “DSCR HELOC” variant. Some network lenders offer one that is reviewed on rental income instead. Whether the first-mortgage payment joins the qualifying payment is not published, so confirm the terms before counting on it.
HELOC, Closed-End Second, or Cash-Out Refinance?
If you want to keep a low first mortgage, a second-lien line is one option. A closed-end second (a home equity loan) pays out a lump sum on a fixed schedule. A cash-out refinance replaces the first loan.
| Factor | Second-lien HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Paid off and replaced |
| Underwritten on | Your credit and DTI | Property rent against payment |
| Title | You or a revocable trust | LLC possible, per program terms |
| Leverage | 70% CLTV on investment | Around 75% LTV, standard rentals |
| Seasoning | Varies by program | About 6 months common |
NerdWallet notes cash-out refinances on investment property are usually limited to 70% to 75%. Across Lendmire’s network, a standard-rental cash-out tops out around 75% LTV. Coverage on a DSCR file starts at 1.00 on select programs, and a separate select-lender path goes below 1.00 with leverage and terms adjusted. The complete DSCR loans guide explains how that test works.
A DSCR cash-out gives you property-rent-based lender review and a clean LLC structure, but it replaces your first mortgage. If that first loan is one you want to keep, the second-lien line has a real edge. The tradeoff is that the line is judged on your personal credit, your DTI must absorb the new payment, and its pricing adjusts over time.
What the Investor Decision Looks Like
Run the decision in this order.
1. Check the first mortgage. Confirm it permits a junior lien and note your balance as a share of value.
2. Compute your room. Subtract your first mortgage share from the maximum combined loan-to-value allowed for an investment condo.
3. Check title. If an LLC holds the deed, a vesting change comes first, or DSCR cash-out becomes the route.
4. Check the building. Look at rental caps, reserves, litigation, and the investor share before you spend time on the numbers.
5. Test your DTI. The new line is qualified on the interest-only payment at the maximum draw, on top of your existing obligations.
6. Decide what the money is for. Down payments on the next rental, rehab, and debt payoff are common uses. A line is not a purchase-money loan for the condo itself.
Keep one point straight: a variable-pricing line adds cash-flow risk. A rental that clears 1.00 on DSCR is not necessarily cash-flowing, because repairs, vacancy, management, utilities, and capital expenses sit outside that calculation. A line whose payment moves with the balance can squeeze a thin property.
Next Steps
Gather your first mortgage statement, deed or trust paperwork, a recent credit report, income or bank-statement documentation, and the condo’s budget, HOA rules, and master insurance. If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, your credit profile, combined leverage, and your goals.

Frequently Asked Questions
Can I get a HELOC on a condo without refinancing my first mortgage?
Often, yes, when the program accepts condos in second position. The line records as a second lien, and your first loan keeps its balance, payment, and terms. Your first note must allow a junior lien, and the CLTV room has to be there.
Does a non-warrantable condo disqualify me?
Not on this network. Non-warrantable condos are eligible, subject to lender guidelines and building review. Condotels are not offered. The building’s budget, reserves, insurance, litigation, and investor share still get reviewed, and passing review is not approval.
Can my LLC hold title to the condo?
Not on this product. Fee simple or leasehold must be held by you personally or in a revocable living trust. If the condo is already deeded to an LLC, you would need a vesting change or a DSCR cash-out refinance instead.
Is a credit score of 720 better than 700 on an investment condo?
Not for the ceiling. Both tiers reach the same 70% CLTV and $500,000 maximum on an investment property. The minimum on investment lines is 700. The 90% tier exists only on primary residences and second homes at 720 and above. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Does this line qualify on my rental income?
No, this product is reviewed on your personal credit and DTI. A DSCR loan is the product that tests property rent against the payment. Some network lenders offer a rent-qualified variant, but its first-mortgage treatment is not published, so ask before relying on it.
